Last updated: 2026-03-17 (runners: homelab, calypso, pi5)
## Overview
This guide explains how to run Ansible playbooks in the homelab infrastructure. Ansible is used for automation, configuration management, and system maintenance across all hosts in the Tailscale network.
## Directory Structure
```
/home/homelab/organized/repos/homelab/ansible/
├── inventory.yml # Primary inventory (YAML format)
├── automation/
│ ├── playbooks/ # Automation and maintenance playbooks
│ ├── hosts.ini # Legacy INI inventory
│ ├── host_vars/ # Per-host variables
│ └── group_vars/ # Group-level variables
├── playbooks/ # Deployment and infrastructure playbooks
│ ├── common/ # Reusable operational playbooks
│ └── deploy_*.yml # Per-host deployment playbooks
└── homelab/
├── playbooks/ # Duplicate of above (legacy)

```
## Prerequisites
1. **Ansible installed** on the control node (homelab machine)
2. **SSH access** to target hosts (configured via Tailscale)
3. **Primary inventory**: `ansible/inventory.yml`
## Running Playbooks
### Basic Syntax
```bash
cd /home/homelab/organized/repos/homelab/
# Using the primary YAML inventory
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/<playbook>.yml
# Target specific hosts
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/<playbook>.yml --limit "homelab,pi-5"
# Dry run (no changes)
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/<playbook>.yml --check
# Verbose output
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/<playbook>.yml -vvv

---
## Important Notes & Warnings
- **TrueNAS SCALE**: Do NOT run apt update — use the web UI only. Excluded from `debian_clients`.
- **Home Assistant**: Manages its own packages. Excluded from `debian_clients`.
- **pi-5-kevin**: Frequently offline — expect `UNREACHABLE` errors.
- **Synology**: `ansible_become: false` — DSM does not use standard sudo.
- **InfluxDB on pi-5**: If apt fails with GPG errors, the source file must use `signed-by=/usr/share/keyrings/influxdata-archive.gpg` (the packaged keyring), not a manually imported key.
## Common Workflows
### Weekly Maintenance
```bash
# 1. Check all hosts are reachable
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/ansible_status_check.yml
# 2. Verify APT cache proxy

# 3. Update all debian_clients
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/update_system.yml --limit debian_clients
# 4. Clean up old packages
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/cleanup.yml
# 5. Check Tailscale connectivity
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/tailscale_health.yml
```
### Adding a New Host
```bash
# 1. Add host to ansible/inventory.yml (and to debian_clients if Debian/Ubuntu)
# 2. Test connectivity
ansible -i ansible/inventory.yml <new-host> -m ping
# 3. Add SSH keys
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/add_ssh_keys.yml --limit <new-host>
# 4. Configure APT proxy
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/configure_apt_proxy.yml --limit <new-host>
# 5. Install standard tools
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/install_tools.yml --limit <new-host>
# 6. Update system
ansible-playbook -i ansible/inventory.yml ansible/automation/playbooks/update_system.yml --limit <new-host>
```
## Ad-Hoc Commands
```bash
# Ping all hosts
ansible -i ansible/inventory.yml all -m ping
# Check disk space
ansible -i ansible/inventory.yml all -m shell -a "df -h" --become
# Restart Docker on a host
ansible -i ansible/inventory.yml homelab -m systemd -a "name=docker state=restarted" --become

keys:
your-api-key: your-api-secret
EOF
# Start LiveKit (run in background)
nohup livekit --config livekit.yml > livekit.log 2>&1 &
```
### 9. Start Services
```bash
# Start all Stoatchat services
./manage-services.sh start
# Check status
./manage-services.sh status
# Test API
curl http://localhost:14702/
# Test frontend (after nginx is configured)
curl https://st.vish.gg
```
### 10. Setup Automated Backups
```bash
# Create backup cron job
cat > setup-backup-cron.sh << 'EOF'
#!/bin/bash
# Add daily backup at 2 AM
(crontab -l 2>/dev/null; echo "0 2 * * * cd /root/stoatchat && ./backup.sh >> backup-cron.log 2>&1") | crontab -
echo "✅ Backup cron job added - daily backups at 2 AM"
echo "Current crontab:"
crontab -l
EOF
chmod +x setup-backup-cron.sh
./setup-backup-cron.sh
```
## ✅ Verification Steps
After deployment, verify everything is working:
```bash
# 1. Check all services
./manage-services.sh status
# 2. Test API endpoints
curl http://localhost:14702/
curl https://api.st.vish.gg
# 3. Test email functionality
curl -X POST http://localhost:14702/auth/account/create \
-H "Content-Type: application/json" \
-d '{"email": "test@yourdomain.com", "password": "TestPass123!"}'
# 4. Check SSL certificates
curl -I https://st.vish.gg
# 5. Test backup system
./backup.sh --dry-run
```
## 🔧 Configuration Customization
### Environment-Specific Settings
Update `Revolt.overrides.toml` with your specific values:
```toml
[database]
redis = "redis://127.0.0.1:6380" # Your Redis connection
[api]
url = "https://api.yourdomain.com" # Your API domain
[api.smtp]
host = "smtp.gmail.com"
port = 465
username = "your-email@gmail.com" # Your Gmail address
password = "REDACTED_PASSWORD" # Your Gmail app password
from_address = "your-email@gmail.com"
use_tls = true
[events]
url = "https://events.yourdomain.com" # Your events domain
[autumn]
url = "https://files.yourdomain.com" # Your files domain
[january]
url = "https://proxy.yourdomain.com" # Your proxy domain
[livekit]
url = "https://voice.yourdomain.com" # Your voice domain
api_key = REDACTED_API_KEY # Your LiveKit API key
api_secret = "your-livekit-api-secret" # Your LiveKit API secret
```
### Gmail App Password Setup
1. Enable 2-Factor Authentication on your Gmail account
2. Go to Google Account settings → Security → App passwords
3. Generate an app password for "Mail"
4. Use this password in the SMTP configuration
## 🚨 Troubleshooting
### Common Issues
1. **Build Fails**: Ensure Rust is installed and up to date
2. **Services Won't Start**: Check port availability and logs
3. **SSL Issues**: Verify domain DNS and certificate renewal
4. **Email Not Working**: Check Gmail app password and SMTP settings
### Log Locations
- **Stoatchat Services**: `*.log` files in the application directory
- **Nginx**: `/var/log/nginx/error.log`
- **System**: `/var/log/syslog`

2. **Portainer** automatically deploys from Gitea repositories
3. **Development tools** ensure quality before deployment
## 📋 Prerequisites
### Required Access
- [ ] **Gitea access** - Your Git repository at `git.vish.gg`
- [ ] **Portainer access** - Web UI for container management
- [ ] **SSH access** - To your homelab servers (optional but recommended)
### Required Tools
- [ ] **Git client** - For repository operations
- [ ] **Text editor** - VS Code recommended (supports DevContainer)
- [ ] **Docker** (optional) - For local testing
## 🚀 Quick Start: Deploy a New Service
### Step 1: Set Up Your Development Environment
#### Option A: Using VS Code DevContainer (Recommended)
```bash
# Clone the repository
git clone https://git.vish.gg/Vish/homelab.git
cd homelab
# Open in VS Code
code .
# VS Code will prompt to "Reopen in Container" - click Yes
# This gives you a pre-configured environment with all tools
```
#### Option B: Manual Setup
```bash
# Clone the repository
git clone https://git.vish.gg/Vish/homelab.git
cd homelab
# Install development tools (if needed)
# Most tools are available via Docker or pre-installed
# Set up Git hooks (optional)
pre-commit install
# Set up environment
cp .env.example .env
# Edit .env with your specific values
```
### Step 2: Create Your Service Configuration
1. **Choose the right location** for your service:
```
hosts/
├── synology/atlantis/ # Main Synology NAS
├── synology/calypso/ # Secondary Synology NAS
├── vms/homelab-vm/ # Primary VM
├── physical/concord-nuc/ # Physical NUC server
└── edge/rpi5-vish/ # Raspberry Pi edge device
```
2. **Create your Docker Compose file**:
```bash
# Example: Adding a new service to the main NAS
touch hosts/synology/atlantis/my-new-service.yml
```
3. **Write your Docker Compose configuration**:
```yaml
# hosts/synology/atlantis/my-new-service.yml
version: '3.8'
services:
my-service:
image: my-service:latest
container_name: my-service
restart: unless-stopped
ports:
- "8080:8080"
volumes:
- /volume1/docker/my-service:/data
environment:
- PUID=1000
- PGID=1000
- TZ=America/New_York
networks:
- homelab
networks:
homelab:
external: true
```
### Step 3: Validate Your Configuration
The new development tools will automatically check your work:
```bash
# Manual validation (optional)
./scripts/validate-compose.sh hosts/synology/atlantis/my-new-service.yml
# Check YAML syntax
yamllint hosts/synology/atlantis/my-new-service.yml
# The pre-commit hooks will run these automatically when you commit
```
### Step 4: Commit and Push
```bash
# Stage your changes
git add hosts/synology/atlantis/my-new-service.yml
# Commit (pre-commit hooks run automatically)
git commit -m "feat: Add my-new-service deployment
- Add Docker Compose configuration for my-service
- Configured for Atlantis NAS deployment
- Includes proper networking and volume mounts"
# Push to Gitea
git push origin main
```
### Step 5: Deploy via Portainer
1. **Access Portainer** (usually at `https://portainer.yourdomain.com`)
2. **Navigate to Stacks**:
- Go to "Stacks" in the left sidebar
- Click "Add stack"
3. **Configure Git deployment**:
- **Name**: `my-new-service`
- **Repository URL**: `https://git.vish.gg/Vish/homelab`
- **Repository reference**: `refs/heads/main`
- **Compose path**: `hosts/synology/atlantis/my-new-service.yml`
- **Automatic updates**: Enable if desired
4. **Deploy**:
- Click "Deploy the stack"
- Monitor the deployment logs
## 🔧 Advanced Workflows
### Local Testing Before Deployment
```bash
# Test your compose file locally
cd hosts/synology/atlantis/
docker compose -f my-new-service.yml config # Validate syntax
docker compose -f my-new-service.yml up -d # Test deployment
docker compose -f my-new-service.yml down # Clean up
```
### Using Environment Variables
1. **Create environment file**:
```bash
# hosts/synology/atlantis/my-service.env
MYSQL_ROOT_PASSWORD="REDACTED_PASSWORD"
MYSQL_DATABASE=myapp
MYSQL_USER=myuser
MYSQL_PASSWORD="REDACTED_PASSWORD"
```
2. **Reference in compose file**:
```yaml
services:
my-service:
env_file:
- my-service.env
```
3. **Add to .gitignore** (for secrets):
```bash
echo "hosts/synology/atlantis/my-service.env" >> .gitignore
```
### Multi-Host Deployments
For services that span multiple hosts:
```bash
# Create configurations for each host
hosts/synology/atlantis/database.yml # Database on NAS
hosts/vms/homelab-vm/app-frontend.yml # Frontend on VM
hosts/physical/concord-nuc/app-api.yml # API on NUC
```
## 🛠️ Troubleshooting
### Pre-commit Hooks Failing
```bash
# See what failed
git commit -m "my changes" # Will show errors
# Fix issues and try again
git add .
git commit -m "my changes"
# Skip hooks if needed (not recommended)
git commit -m "my changes" --no-verify
```
### Portainer Deployment Issues
1. **Check Portainer logs**:
- Go to Stacks → Your Stack → Logs
2. **Verify file paths**:
- Ensure the compose path in Portainer matches your file location
3. **Check Git access**:
- Verify Portainer can access your Gitea repository
### Docker Compose Validation Errors
```bash
# Get detailed error information
docker compose -f your-file.yml config
# Common issues:
# - Indentation errors (use spaces, not tabs)
# - Missing quotes around special characters
# - Invalid port mappings
# - Non-existent volume paths
```
## 📚 Best Practices
### File Organization
- **Group related services** in the same directory
- **Use descriptive filenames** (`service-name.yml`)
- **Include documentation** in comments
### Security
- **Never commit secrets** to Git
- **Use environment files** for sensitive data
- **Set proper file permissions** on secrets
### Networking
- **Use the `homelab` network** for inter-service communication
- **Document port mappings** in comments
- **Avoid port conflicts** across services
### Volumes
- **Use consistent paths** (`/volume1/docker/service-name`)
- **Set proper ownership** (PUID/PGID)
- **Document data locations** for backups
## 🔗 Quick Reference
### Common Commands
```bash
# Validate all compose files
./scripts/validate-compose.sh
# Check specific file
./scripts/validate-compose.sh hosts/synology/atlantis/service.yml
# Run pre-commit checks manually
pre-commit run --all-files
# Update pre-commit hooks
pre-commit autoupdate
```
### File Locations
- **Service configs**: `hosts/{host-type}/{host-name}/service.yml`
- **Documentation**: `docs/`
- **Scripts**: `scripts/`
- **Development tools**: `.devcontainer/`, `.pre-commit-config.yaml`, etc.
### Portainer Stack Naming
- Use descriptive names: `atlantis-media-stack`, `homelab-monitoring`
- Include host prefix for clarity
- Keep names consistent with file names
## 🆘 Getting Help
1. **Check existing services** for examples
2. **Review validation errors** carefully
3. **Test locally** before pushing
4. **Use the development environment** for consistent tooling
---
*This workflow ensures reliable, tested deployments while maintaining the flexibility of your GitOps setup.*

# 🛠️ Development Environment Setup
This document describes how to set up a development environment for the Homelab repository with automated validation, linting, and quality checks.
## 🚀 Quick Start
1. **Clone the repository** (if not already done):
```bash
git clone https://git.vish.gg/Vish/homelab.git
cd homelab
```
2. **Run the setup script**:
```bash
./scripts/setup-dev-environment.sh
```
3. **Configure your environment**:
```bash
cp .env.example .env
# Edit .env with your actual values
```
4. **Test the setup**:
```bash
yamllint hosts/
./scripts/validate-compose.sh
```
## 📋 What Gets Installed
### Core Tools
- **yamllint**: YAML file validation and formatting
- **pre-commit**: Git hooks for automated checks
- **ansible-lint**: Ansible playbook validation
- **Docker Compose validation**: Syntax checking for service definitions
### Pre-commit Hooks
The following checks run automatically before each commit:
- ✅ YAML syntax validation
- ✅ Docker Compose file validation
- ✅ Trailing whitespace removal
- ✅ Large file detection (>10MB)
- ✅ Merge conflict detection
- ✅ Ansible playbook linting
## 🔧 Manual Commands
### YAML Linting
```bash
# Lint all YAML files
yamllint .
# Lint specific directory
yamllint hosts/
# Lint specific file
yamllint hosts/atlantis/immich.yml
```
### Docker Compose Validation
```bash
# Validate all compose files
./scripts/validate-compose.sh
# Validate specific file
./scripts/validate-compose.sh hosts/atlantis/immich.yml
# Validate multiple files
./scripts/validate-compose.sh hosts/atlantis/*.yml
```
### Pre-commit Checks
```bash
# Run all checks on all files
pre-commit run --all-files
# Run checks on staged files only
pre-commit run
# Run specific hook
pre-commit run yamllint
# Skip hooks for a commit (use sparingly)
git commit --no-verify -m "Emergency fix"
```
## 🐳 DevContainer Support
For VS Code users, a DevContainer configuration is provided:
1. Install the "Dev Containers" extension in VS Code
2. Open the repository in VS Code
3. Click "Reopen in Container" when prompted
4. The environment will be automatically set up with all tools
### DevContainer Features
- Ubuntu 22.04 base image
- Docker-in-Docker support
- Python 3.11 with all dependencies
- Pre-configured VS Code extensions
- Automatic pre-commit hook installation
## 📁 File Structure
```
homelab/
├── .devcontainer/ # VS Code DevContainer configuration
├── .pre-commit-config.yaml # Pre-commit hooks configuration
├── .yamllint # YAML linting rules
├── .env.example # Environment variables template
├── requirements.txt # Python dependencies
├── scripts/
│ ├── setup-dev-environment.sh # Setup script
│ └── validate-compose.sh # Docker Compose validator
└── DEVELOPMENT.md # This file
```
## 🔒 Security & Best Practices
### Environment Variables
- Never commit `.env` files
- Use `.env.example` as a template
- Store secrets in your local `.env` file only
### Pre-commit Hooks
- Hooks prevent broken commits from reaching the repository
- They run locally before pushing to Gitea
- Failed hooks will prevent the commit (fix issues first)
### Docker Compose Validation
- Validates syntax before deployment
- Checks for common configuration issues
- Warns about potential problems (localhost references, missing restart policies)
## 🚨 Troubleshooting
### Pre-commit Hook Failures
```bash
# If hooks fail, fix the issues and try again
git add .
git commit -m "Fix validation issues"
# To see what failed:
pre-commit run --all-files --verbose
```
### Docker Compose Validation Errors
```bash
# Test a specific file manually:
docker-compose -f hosts/atlantis/immich.yml config
# Check the validation script output:
./scripts/validate-compose.sh hosts/atlantis/immich.yml
```
### YAML Linting Issues
```bash
# See detailed linting output:
yamllint -f parsable hosts/
# Fix common issues:
# - Use 2 spaces for indentation
# - Remove trailing whitespace
# - Use consistent quote styles
```
### Python Dependencies
```bash
# If pip install fails, try:
python3 -m pip install --user --upgrade pip
python3 -m pip install --user -r requirements.txt
# For permission issues:
pip install --user -r requirements.txt
```
## 🔄 Integration with Existing Workflow
This development setup **does not interfere** with your existing Portainer GitOps workflow:
- ✅ Portainer continues to poll and deploy as usual
- ✅ All existing services keep running unchanged
- ✅ Pre-commit hooks only add validation, no deployment changes
- ✅ You can disable hooks anytime with `pre-commit uninstall`
## 📈 Benefits
### Before (Manual Process)
- Manual YAML validation
- Syntax errors discovered after deployment
- Inconsistent formatting
- No automated quality checks
### After (Automated Process)
- ✅ Automatic validation before commits
- ✅ Consistent code formatting
- ✅ Early error detection
- ✅ Improved code quality
- ✅ Faster debugging
- ✅ Better collaboration
## 🆘 Getting Help
If you encounter issues:
1. **Check the logs**: Most tools provide detailed error messages
2. **Run setup again**: `./scripts/setup-dev-environment.sh`
3. **Manual validation**: Test individual files with the validation tools
4. **Skip hooks temporarily**: Use `git commit --no-verify` for emergencies
## 🎯 Next Steps
Once the development environment is working:
1. **Phase 2**: Set up Gitea Actions for CI/CD
2. **Phase 3**: Add automated deployment validation
3. **Phase 4**: Implement infrastructure as code with Terraform
---
*This development setup is designed to be non-intrusive and can be disabled at any time by running `pre-commit uninstall`.*

```bash
# Check DokuWiki accessibility
curl -I http://atlantis.vish.local:8399/doku.php?id=homelab:start
# Verify SSH access to Atlantis
ssh -p 60000 vish@192.168.0.200 "echo 'SSH connection successful'"
# Check DokuWiki data directory permissions
ssh -p 60000 vish@192.168.0.200 "
ls -la /volume1/@appdata/REDACTED_APP_PASSWORD/all_shares/metadata/docker/dokuwiki/dokuwiki/data/pages/
"
```
#### Gitea Wiki API Issues
```bash
# Test API connectivity
curl -H "Authorization: token $GITEA_TOKEN" \
"$GITEA_URL/api/v1/repos/$REPO_OWNER/$REPO_NAME/wiki"
# Verify token permissions
curl -H "Authorization: token $GITEA_TOKEN" \
"$GITEA_URL/api/v1/user"
```
#### Repository Sync Issues
```bash
# Check Git status
git status
git log --oneline -5
# Verify remote connectivity
git remote -v
git fetch origin
```

# Gitea Actions & Runner Guide
*How to use the `calypso-runner` for homelab automation*
## Overview
The `calypso-runner` is a Gitea Act Runner running on Calypso (`gitea/act_runner:latest`).
It picks up jobs from any workflow in any repo it's registered to and executes them in
Docker containers. A single runner handles all workflows sequentially — for a homelab this
is plenty.
**Runner labels** (what `runs-on:` values work):
| `runs-on:` value | Container used |
|---|---|
| `ubuntu-latest` | `node:20-bookworm` |
| `ubuntu-22.04` | `ubuntu:22.04` |
| `python` | `python:3.11` |
Workflows go in `.gitea/workflows/*.yml`. They use the same syntax as GitHub Actions.
---
## Existing workflows
| File | Trigger | What it does |
|---|---|---|
| `mirror-to-public.yaml` | push to main | Sanitizes repo and force-pushes to `homelab-optimized` |
| `validate.yml` | every push + PR | YAML lint + secret scan on changed files |
| `portainer-deploy.yml` | push to main (hosts/ changed) | Auto-redeploys matching Portainer stacks |
| `dns-audit.yml` | daily 08:00 UTC + manual | DNS resolution, NPM↔DDNS cross-reference, CF proxy audit |
---
## Repo secrets
Stored at: **Gitea → Vish/homelab → Settings → Secrets → Actions**
| Secret | Used by | Notes |
|---|---|---|
| `PUBLIC_REPO_TOKEN` | mirror-to-public | Write access to homelab-optimized |
| `PUBLIC_REPO_URL` | mirror-to-public | URL of the public mirror repo |
| `PORTAINER_TOKEN` | portainer-deploy | `ptr_*` Portainer API token |
| `GIT_TOKEN` | portainer-deploy, dns-audit | Gitea token for repo checkout + Portainer git auth |
| `NTFY_URL` | portainer-deploy, dns-audit | Full ntfy topic URL (optional) |
| `NPM_EMAIL` | dns-audit | NPM admin email for API login |
| `NPM_PASSWORD` | dns-audit | NPM admin password for API login |
| `CF_TOKEN` | dns-audit | Cloudflare API token (same one used by DDNS containers) |
| `CF_SYNC` | dns-audit | Set to `true` to auto-patch CF proxy mismatches (optional) |
> Note: Gitea reserves the `GITEA_` prefix for built-in variables — use `GIT_TOKEN`
> not `GITEA_TOKEN`.
---
## Workflow recipes
### DNS record audit
This is a live workflow — see `.gitea/workflows/dns-audit.yml` and the full
documentation at `docs/guides/dns-audit.md`.
It runs the script at `.gitea/scripts/dns-audit.py` which does a 5-step audit:
1. Parses all DDNS compose files for the canonical domain + proxy-flag list
2. Queries the NPM API for all proxy host domains
3. Live DNS checks — proxied domains must resolve to CF IPs, unproxied to direct IPs
4. Cross-references NPM ↔ DDNS (flags orphaned entries in either direction)
5. Cloudflare API audit — checks proxy settings match DDNS config; auto-patches with `CF_SYNC=true`
Required secrets: `GIT_TOKEN`, `NPM_EMAIL`, `NPM_PASSWORD`, `CF_TOKEN` <!-- pragma: allowlist secret -->
Optional: `NTFY_URL` (alert on failure), `CF_SYNC=true` (auto-patch mismatches)
---
### Ansible dry-run on changed playbooks
Validates any Ansible playbook you change before it gets used in production.
Requires your inventory to be reachable from the runner.
```yaml
# .gitea/workflows/ansible-check.yml
name: Ansible Check
on:
push:
paths: ['ansible/**']
pull_request:
paths: ['ansible/**']
jobs:
ansible-lint:
runs-on: ubuntu-22.04
steps:
- uses: actions/checkout@v4
- name: Install Ansible
run: |
apt-get update -q && apt-get install -y -q ansible ansible-lint
- name: Syntax check changed playbooks
run: |
CHANGED=$(git diff --name-only HEAD~1 HEAD | grep 'ansible/.*\.yml$' || true)
if [ -z "$CHANGED" ]; then
echo "No playbooks changed"
exit 0
fi
for playbook in $CHANGED; do
echo "Checking: $playbook"
ansible-playbook --syntax-check "$playbook" -i ansible/homelab/inventory/ || exit 1
done
- name: Lint changed playbooks
run: |
CHANGED=$(git diff --name-only HEAD~1 HEAD | grep 'ansible/.*\.yml$' || true)
if [ -z "$CHANGED" ]; then exit 0; fi
ansible-lint $CHANGED --exclude ansible/archive/
```
---
### Notify on push
Sends an ntfy notification with a summary of every push to main — who pushed,
what changed, and a link to the commit.
```yaml
# .gitea/workflows/notify-push.yml
name: Notify on Push
on:
push:
branches: [main]
jobs:
notify:
runs-on: python
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 2
- name: Send push notification
env:
NTFY_URL: ${{ secrets.NTFY_URL }}
run: |
python3 << 'PYEOF'
import subprocess, requests, os
ntfy_url = os.environ.get('NTFY_URL', '')
if not ntfy_url:
print("NTFY_URL not set, skipping")
exit()
author = subprocess.check_output(
['git', 'log', '-1', '--format=%an'], text=True).strip()
message = subprocess.check_output(
['git', 'log', '-1', '--format=%s'], text=True).strip()
changed = subprocess.check_output(
['git', 'diff', '--name-only', 'HEAD~1', 'HEAD'], text=True).strip()
file_count = len(changed.splitlines()) if changed else 0
sha = subprocess.check_output(
['git', 'rev-parse', '--short', 'HEAD'], text=True).strip()
body = f"{message}\n{file_count} file(s) changed\nCommit: {sha}"
requests.post(ntfy_url,
data=body,
headers={'Title': f'📦 Push by {author}', 'Priority': '2', 'Tags': 'inbox_tray'},
timeout=10)
print(f"Notified: {message}")
PYEOF
```
---
### Scheduled service health check
Pings all your services and sends an alert if any are down. Runs every 30 minutes.
```yaml
# .gitea/workflows/health-check.yml
name: Service Health Check
on:
schedule:
- cron: '*/30 * * * *' # every 30 minutes
workflow_dispatch:
jobs:
health:
runs-on: python
steps:
- name: Check services
env:
NTFY_URL: ${{ secrets.NTFY_URL }}
run: |
pip install requests -q
python3 << 'PYEOF'
import requests, os, sys
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
# Services to check: (name, url, expected_status)
SERVICES = [
('Gitea', 'https://git.vish.gg', 200),
('Portainer', 'https://192.168.0.200:9443', 200),

if r.status_code == expected or r.status_code in [200, 301, 302, 401, 403]:
print(f"OK {name} ({r.status_code})")
else:
down.append(f"{name}: HTTP {r.status_code}")
print(f"ERR {name}: HTTP {r.status_code}")
except Exception as e:
down.append(f"{name}: unreachable ({e})")
print(f"ERR {name}: {e}")
ntfy_url = os.environ.get('NTFY_URL', '')
if down:
if ntfy_url:
requests.post(ntfy_url,
data='\n'.join(down),
headers={'Title': '🚨 Services Down', 'Priority': '5', 'Tags': 'rotating_light'},
timeout=10)
sys.exit(1)
PYEOF
```
---
### Backup verification
Checks that backup files on your NAS are recent and non-empty. Uses SSH to
check file modification times.
```yaml
# .gitea/workflows/backup-verify.yml
name: Backup Verification
on:
schedule:
- cron: '0 10 * * *' # daily at 10:00 UTC (after nightly backups complete)
workflow_dispatch:
jobs:
verify:
runs-on: ubuntu-22.04
steps:
- name: Check backups via SSH
env:
NTFY_URL: ${{ secrets.NTFY_URL }}
SSH_KEY: ${{ secrets.BACKUP_SSH_KEY }} # add this secret: private SSH key
run: |
# Write SSH key
mkdir -p ~/.ssh
echo "$SSH_KEY" > ~/.ssh/id_rsa
chmod 600 ~/.ssh/id_rsa
ssh-keyscan -H 192.168.0.200 >> ~/.ssh/known_hosts 2>/dev/null
# Check that backup directories exist and have files modified in last 24h
ssh -i ~/.ssh/id_rsa homelab@192.168.0.200 << 'SSHEOF'
MAX_AGE_HOURS=24
BACKUP_DIRS=(
"/volume1/backups/paperless"
"/volume1/backups/vaultwarden"
"/volume1/backups/immich"
)
FAILED=0
for dir in "${BACKUP_DIRS[@]}"; do
RECENT=$(find "$dir" -newer /tmp/.timeref -name "*.tar*" -o -name "*.sql*" 2>/dev/null | head -1)
if [ -z "$RECENT" ]; then
echo "STALE: $dir (no recent backup found)"
FAILED=1
else
echo "OK: $dir -> $(basename $RECENT)"
fi
done
exit $FAILED
SSHEOF
```
> To use this, add a `BACKUP_SSH_KEY` secret containing the private key for a
> user with read access to your backup directories.
---
### Docker image update check
Checks for newer versions of your key container images and notifies you without
automatically pulling — gives you a heads-up to review before Watchtower does it.
```yaml
# .gitea/workflows/image-check.yml
name: Image Update Check
on:
schedule:
- cron: '0 9 * * 1' # every Monday at 09:00 UTC
workflow_dispatch:
jobs:
check:
runs-on: python
steps:
- name: Check for image updates
env:
NTFY_URL: ${{ secrets.NTFY_URL }}
run: |
pip install requests -q
python3 << 'PYEOF'
import requests, os
# Images to track: (friendly name, image, current tag)
IMAGES = [
('Authentik', 'ghcr.io/goauthentik/server', 'latest'),
('Gitea', 'gitea/gitea', 'latest'),
('Immich', 'ghcr.io/immich-app/immich-server', 'release'),
('Paperless', 'ghcr.io/paperless-ngx/paperless-ngx', 'latest'),
('Vaultwarden', 'vaultwarden/server', 'latest'),
('Stoatchat', 'ghcr.io/stoatchat/backend', 'latest'),
]
updates = []
for name, image, tag in IMAGES:
try:
# Check Docker Hub or GHCR for latest digest
if image.startswith('ghcr.io/'):
repo = image[len('ghcr.io/'):]
r = requests.get(
f'https://ghcr.io/v2/{repo}/manifests/{tag}',
headers={'Accept': 'application/vnd.oci.image.index.v1+json'},
timeout=10)
digest = r.headers.get('Docker-Content-Digest', 'unknown')
else:
r = requests.get(
f'https://hub.docker.com/v2/repositories/{image}/tags/{tag}',
timeout=10).json()
digest = r.get('digest', 'unknown')
print(f"OK {name}: {digest[:20]}...")
updates.append(f"{name}: {digest[:16]}...")
except Exception as e:
print(f"ERR {name}: {e}")
ntfy_url = os.environ.get('NTFY_URL', '')
if ntfy_url and updates:
requests.post(ntfy_url,
data='\n'.join(updates),
headers={'Title': '📋 Weekly Image Digest Check', 'Priority': '2', 'Tags': 'docker'},
timeout=10)
PYEOF
```
---
## How to add a new workflow
1. Create a file in `.gitea/workflows/yourname.yml`
2. Set `runs-on:` to one of: `ubuntu-latest`, `ubuntu-22.04`, or `python`
3. Use `${{ secrets.SECRET_NAME }}` for any tokens/passwords
4. Push to main — the runner picks it up immediately
5. View results: **Gitea → Vish/homelab → Actions**
## How to run a workflow manually
Any workflow with `workflow_dispatch:` in its trigger can be run from the UI:
**Gitea → Vish/homelab → Actions → select workflow → Run workflow**
## Cron schedule reference
```
┌─ minute (0-59)
│ ┌─ hour (0-23, UTC)
│ │ ┌─ day of month (1-31)
│ │ │ ┌─ month (1-12)
│ │ │ │ ┌─ day of week (0=Sun, 6=Sat)
│ │ │ │ │
* * * * *
Examples:
0 8 * * * = daily at 08:00 UTC
*/30 * * * * = every 30 minutes
0 9 * * 1 = every Monday at 09:00 UTC
0 2 * * 0 = every Sunday at 02:00 UTC
```
## Debugging a failed workflow
```bash
# View runner logs on Calypso via Portainer API
curl -sk -H "X-API-Key: $PORTAINER_TOKEN" \
"https://192.168.0.200:9443/api/endpoints/443397/docker/containers/json?all=true" | \
jq -r '.[] | select(.Names[0]=="/gitea-runner") | .Id' | \
xargs -I{} curl -sk -H "X-API-Key: $PORTAINER_TOKEN" \
"https://192.168.0.200:9443/api/endpoints/443397/docker/containers/{}/logs?stdout=1&stderr=1&tail=50" | strings
```
Or view run results directly in the Gitea UI:
**Gitea → Vish/homelab → Actions → click any run**

# GitOps Deployment Comprehensive Guide
*Last Updated: March 8, 2026*
## 🎯 Overview
This homelab infrastructure is deployed using **GitOps methodology** with **Portainer Enterprise Edition** as the orchestration platform. All services are defined as Docker Compose files in this Git repository and automatically deployed across multiple hosts.
## 🏗️ GitOps Architecture
### Core Components
- **Git Repository**: Source of truth for all infrastructure configurations
- **Portainer EE**: GitOps orchestration and container management (v2.33.7)
- **Docker Compose**: Service definition and deployment format
- **Multi-Host Deployment**: Services distributed across Synology NAS, VMs, and edge devices
### Current Deployment Status
**Verified Active Stacks**: 81 compose stacks across 5 endpoints — all GitOps-managed
**Total Containers**: 157+ containers across infrastructure
**Management Interface**: https://192.168.0.200:9443 (Portainer EE)
## 📊 Active GitOps Deployments
All 5 endpoints are fully GitOps-managed. Every stack uses the canonical `hosts/` path.

## 🚀 GitOps Workflow
### 1. Service Definition
Services are defined using Docker Compose YAML files in the repository:
```yaml
# Example: Atlantis/new-service.yaml
version: '3.8'
services:
new-service:
image: example/service:latest
container_name: new-service
ports:
- "8080:8080"
environment:
- ENV_VAR=value
volumes:
- /volume1/docker/new-service:/data
restart: unless-stopped
```
### 2. Git Commit & Push
```bash
# Add new service configuration
git add Atlantis/new-service.yaml
git commit -m "Add new service deployment
- Configure new-service with proper volumes
- Set up environment variables
- Enable auto-restart policy"
# Push to trigger GitOps deployment
git push origin main
```
### 3. Automatic Deployment
- Portainer monitors the Git repository for changes
- New commits trigger automatic stack updates
- Services are deployed/updated across the infrastructure
- Health checks verify successful deployment
### 4. Monitoring & Verification
```bash
# Check deployment status
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker compose ls"
# Verify service health
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker ps | grep new-service"
```
## 📁 Repository Structure for GitOps
### Host-Specific Configurations
All stacks use canonical `hosts/` paths. The root-level legacy directories (`Atlantis/`, `Calypso/`, etc.) are symlinks kept only for backwards compatibility — do not use them for new stacks.

ssh -p 60000 vish@192.168.0.200 "sudo rm -rf /volume1/docker/old-service"
```
## 🔍 Monitoring & Troubleshooting
### GitOps Health Checks
#### Check Portainer Status
```bash
# Verify Portainer is running
curl -k -s "https://192.168.0.200:9443/api/system/status"
# Check container status
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker ps | grep portainer"
```
#### Verify Git Sync Status
```bash
# Check if Portainer can access Git repository
# (Check via Portainer UI: Stacks → Repository sync status)
# Verify latest commits are reflected
git log --oneline -5
```
#### Monitor Stack Deployments
```bash
# List all active stacks
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker compose ls"
# Check specific stack status
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker compose -f /path/to/stack.yaml ps"
```
### Common Issues & Solutions
#### Stack Deployment Fails
1. **Check YAML Syntax**
```bash
# Validate YAML syntax
yamllint Atlantis/service.yaml
# Check Docker Compose syntax
docker-compose -f Atlantis/service.yaml config
```
2. **Review Portainer Logs**
```bash
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker logs portainer"
```
3. **Check Resource Constraints**
```bash
# Verify disk space
ssh -p 60000 vish@192.168.0.200 "df -h"
# Check memory usage
ssh -p 60000 vish@192.168.0.200 "free -h"
```
#### Git Repository Access Issues
1. **Verify Repository URL**
2. **Check Authentication credentials**
3. **Confirm network connectivity**
#### Service Won't Start
1. **Check container logs**
```bash
ssh -p 60000 vish@192.168.0.200 "sudo /usr/local/bin/docker logs service-name"
```
2. **Verify port conflicts**
```bash
ssh -p 60000 vish@192.168.0.200 "sudo netstat -tulpn | grep :PORT"
```
3. **Check volume mounts**
```bash
ssh -p 60000 vish@192.168.0.200 "ls -la /volume1/docker/service-name"
```
## 🔐 Security Considerations
### GitOps Security Best Practices
- **Repository Access**: Secure Git repository with appropriate access controls
- **Secrets Management**: Use Docker secrets or external secret management
- **Network Security**: Services deployed on isolated Docker networks
- **Regular Updates**: Watchtower ensures containers stay updated
### Access Control
- **Portainer Authentication**: Multi-user access with role-based permissions
- **SSH Access**: Key-based authentication for server management
- **Service Authentication**: Individual service authentication where applicable
## 📈 Performance & Scaling
### Resource Monitoring
- **Container Metrics**: Monitor CPU, memory, and disk usage
- **Network Performance**: Track bandwidth and connection metrics
- **Storage Utilization**: Monitor disk space across all hosts
### Scaling Strategies
- **Horizontal Scaling**: Deploy services across multiple hosts
- **Load Balancing**: Use Nginx Proxy Manager for traffic distribution
- **Resource Optimization**: Optimize container resource limits
## 🔄 Backup & Disaster Recovery
### GitOps Backup Strategy
- **Repository Backup**: Git repository is the source of truth
- **Configuration Backup**: All service configurations version controlled
- **Data Backup**: Persistent volumes backed up separately
### Recovery Procedures
1. **Service Recovery**: Redeploy from Git repository
2. **Data Recovery**: Restore from backup volumes
3. **Full Infrastructure Recovery**: Bootstrap new hosts with GitOps

# Git Branches Guide for Homelab Repository
Last updated: 2026-02-17
## What Are Git Branches?
Branches are like parallel timelines for your code. They let you make changes without affecting the main codebase. Your `main` branch is the "production" version - stable and working. Other branches let you experiment safely.
## Why Use Branches?
1. **Safety**: Your production services keep running while you test changes
2. **Collaboration**: If someone helps you, they can work on their own branch
3. **Easy Rollback**: If something breaks, just delete the branch or don't merge it
4. **Code Review**: You can review changes before merging (especially useful for risky changes)
5. **Parallel Work**: Work on multiple things at once without conflicts
## Common Use Cases for This Homelab
### 1. Feature Development
Adding new services or functionality without disrupting main branch.
```bash
git checkout -b feature/add-jellyfin
# Make changes, test, commit
git push origin feature/add-jellyfin
# When ready, merge to main
```
**Example**: Adding a new service like Jellyfin - you can configure it, test it, document it all in isolation.
### 2. Bug Fixes
Isolating fixes for specific issues.
```bash
git checkout -b fix/perplexica-timeout
# Fix the issue, test
# Merge when confirmed working
```
**Example**: Like the `fix/admin-acl-routing` branch - fixing specific issues without touching main.
### 3. Experiments/Testing
Try new approaches without risk.
```bash
git checkout -b experiment/traefik-instead-of-nginx
# Try completely different approach
# If it doesn't work, just delete the branch
```
**Example**: Testing if Traefik works better than Nginx Proxy Manager without risking your working setup.
### 4. Documentation Updates
Large documentation efforts.
```bash
git checkout -b docs/monitoring-guide
# Write extensive docs
# Merge when complete
```
### 5. Major Refactors
Restructure code over time.
```bash
git checkout -b refactor/reorganize-compose-files
# Restructure files over several days
# Main stays working while you experiment
```
## Branch Naming Convention
Recommended naming scheme:
- `feature/*` - New services/functionality
- `fix/*` - Bug fixes
- `docs/*` - Documentation only
- `experiment/*` - Testing ideas (might not merge)
- `upgrade/*` - Service upgrades
- `config/*` - Configuration changes
- `security/*` - Security updates
## Standard Workflow
### Starting New Work
```bash
# Always start from updated main
git checkout main
git pull origin main
# Create your branch
git checkout -b feature/new-service-name
# Work, commit, push
git add .
git commit -m "Add new service config"
git push origin feature/new-service-name
```
### When Ready to Merge
```bash
# Update main first
git checkout main
git pull origin main
# Merge your branch (--no-ff creates merge commit for history)
git merge feature/new-service-name --no-ff -m "Merge feature/new-service-name"
# Push and cleanup
git push origin main
git push origin --delete feature/new-service-name
# Delete local branch
git branch -d feature/new-service-name
```
## Real Examples for This Homelab
**Good branch names:**
- `feature/add-immich` - Adding new photo service
- `fix/plex-permissions` - Fixing Plex container permissions
- `docs/ansible-playbook-guide` - Documentation work
- `upgrade/ollama-version` - Upgrading a service
- `experiment/kubernetes-migration` - Testing big changes
- `security/update-vaultwarden` - Security updates
## When to Use Branches
### ✅ Use a branch when:
- Adding a new service
- Making breaking changes
- Experimenting with new tools
- Major configuration changes
- Working on something over multiple days
- Multiple files will be affected
- Changes need testing before production
### ❌ Direct to main is fine for:
- Quick documentation fixes
- Typo corrections
- Emergency hotfixes (but still be careful!)
- Single-line configuration tweaks
## Quick Command Reference
```bash
# List all branches (local and remote)
git branch -a
# Create and switch to new branch
git checkout -b branch-name
# Switch to existing branch
git checkout branch-name
# See current branch
git branch
# Push branch to remote
git push origin branch-name
# Delete local branch
git branch -d branch-name
# Delete remote branch
git push origin --delete branch-name
# Update local list of remote branches
git fetch --prune
# See branch history
git log --oneline --graph --all --decorate
# Create backup branch before risky operations
git checkout -b backup-main-$(date +%Y-%m-%d)
```
## Merge Strategies
### Fast-Forward Merge (default)
Branch commits are simply added to main. Clean linear history.
```bash
git merge feature-branch
```
### No Fast-Forward Merge (recommended)
Creates merge commit showing branch integration point. Better for tracking features.
```bash
git merge feature-branch --no-ff
```
### Squash Merge
Combines all branch commits into one commit on main. Cleaner but loses individual commit history.
```bash
git merge feature-branch --squash
```
## Conflict Resolution
If merge conflicts occur:
```bash
# Git will tell you which files have conflicts
# Edit the files to resolve conflicts (look for <<<<<<< markers)
# After resolving, stage the files
git add resolved-file.yml
# Complete the merge
git commit
```
## Best Practices
1. **Keep branches short-lived**: Merge within days/weeks, not months
2. **Update from main regularly**: Prevent large divergence
3. **One feature per branch**: Don't mix unrelated changes
4. **Descriptive names**: Use naming convention for clarity
5. **Test before merging**: Verify changes work
6. **Delete after merging**: Keep repository clean
7. **Create backups**: Before risky merges, create backup branch
## Recovery Commands
```bash
# Undo last commit (keep changes)
git reset --soft HEAD~1
# Abandon all local changes
git reset --hard HEAD
# Restore from backup branch
git checkout main
git reset --hard backup-main-2026-02-17
# See what changed in merge
git diff main feature-branch
```
## Integration with This Repository
This repository follows these practices:
- `main` branch is always deployable
- Feature branches are merged with `--no-ff` for clear history
- Backup branches created before major merges (e.g., `backup-main-2026-02-17`)
- Remote branches deleted after successful merge
- Documentation changes may go direct to main if minor

# Docker Image Update Strategy
Last updated: 2026-03-17
## Overview
The homelab uses a multi-layered approach to keeping Docker images up to date, combining automated detection, GitOps deployment, and manual controls.
```
Renovate (weekly scan) ──► Creates PR with version bumps
│
Merge PR to main
│
portainer-deploy.yml (CI) ──► Redeploys changed stacks (pullImage=true)
│
Images pulled & containers recreated
│
DIUN (weekly scan) ──────► Notifies via ntfy if images still outdated
│
Watchtower (on-demand) ──► Manual trigger for emergency updates
```
## Update Mechanisms
### 1. Renovate Bot (Recommended — GitOps)
Renovate scans all compose files weekly and creates PRs to bump image tags.
| Setting | Value |
|---------|-------|
| **Schedule** | Mondays 06:00 UTC |
| **Workflow** | `.gitea/workflows/renovate.yml` |
| **Config** | `renovate.json` |
| **Automerge** | No (requires manual review) |
| **Minimum age** | 3 days (avoids broken releases) |
| **Scope** | All `docker-compose` files in `hosts/` |
**How it works:**
1. Renovate detects new image versions in compose files
2. Creates a PR on Gitea (e.g., "Update linuxserver/sonarr to v4.1.2")
3. You review and merge the PR
4. `portainer-deploy.yml` CI triggers and redeploys the stack with `pullImage: true`
5. Portainer pulls the new image and recreates the container
**Manual trigger:**
```bash
# Run Renovate on-demand from Gitea UI:
# Actions → renovate → Run workflow
```
### 2. Portainer GitOps Auto-Deploy (CI/CD)
When compose files are pushed to `main`, the CI workflow auto-redeploys affected stacks.
| Setting | Value |
|---------|-------|
| **Workflow** | `.gitea/workflows/portainer-deploy.yml` |
| **Trigger** | Push to `main` touching `hosts/**` or `common/**` |
| **Pull images** | Yes (`pullImage: true` in redeploy request) |
| **Endpoints** | Atlantis, Calypso, NUC, Homelab VM, RPi 5 |
**All stacks across all endpoints are GitOps-linked (as of 2026-03-17).** Every stack has a `GitConfig` pointing to the repo, so any compose file change triggers an automatic redeploy.
**To update a specific service manually via GitOps:**
```bash
# Edit the compose file to bump the image tag
vim hosts/synology/atlantis/sonarr.yaml
# Change: image: linuxserver/sonarr:latest
# To: image: linuxserver/sonarr:4.1.2
# Commit and push
git add hosts/synology/atlantis/sonarr.yaml
git commit -m "feat: update sonarr to 4.1.2"
git push
# CI auto-deploys within ~30 seconds
```
### 3. DIUN — Docker Image Update Notifier (Detection)
DIUN monitors all running containers and sends ntfy notifications when upstream images have new digests.
| Setting | Value |
|---------|-------|
| **Host** | Atlantis |
| **Schedule** | Mondays 09:00 UTC (3 hours after Renovate) |
| **Compose** | `hosts/synology/atlantis/diun.yaml` |
| **Notifications** | ntfy topic `diun` (https://ntfy.vish.gg/diun) |
DIUN is detection-only — it tells you what's outdated but doesn't update anything. If Renovate missed something (e.g., a `:latest` tag with a new digest), DIUN will catch it.
### 4. Watchtower (On-Demand Manual Updates)
Watchtower runs on 3 endpoints with automatic updates **disabled**. It's configured for manual HTTP API triggers only.
| Setting | Value |
|---------|-------|
| **Hosts** | Atlantis, Calypso, Homelab VM |
| **Schedule** | Disabled (manual only) |
| **Compose** | `common/watchtower-full.yaml` |
| **API port** | 8083 (configurable via `WATCHTOWER_PORT`) |
| **Notifications** | ntfy via shoutrrr |
**Trigger a manual update on a specific host:**
```bash
# Atlantis
curl -X POST http://192.168.0.200:8083/v1/update \
-H "Authorization: Bearer watchtower-metrics-token"
# Calypso
curl -X POST http://192.168.0.250:8083/v1/update \
-H "Authorization: Bearer watchtower-metrics-token"
# Homelab VM
curl -X POST http://localhost:8083/v1/update \
-H "Authorization: Bearer watchtower-metrics-token"
```
This pulls the latest image for every container on that host and recreates any that have newer images. Use sparingly — it updates everything at once.
**Exclude a container from Watchtower:**
```yaml
labels:
- "com.centurylinklabs.watchtower.enable=false"
```
### 5. Portainer UI (Manual Per-Stack)
For individual stack updates via the Portainer web UI:
1. Go to https://192.168.0.200:9443
2. Navigate to Stacks → select the stack
3. Click **Pull and redeploy** (pulls latest images)
4. Or click **Update the stack** → check "Pull latest image"
## Recommended Workflow
### Weekly Routine (Automated)
```
Monday 06:00 UTC → Renovate creates PRs for version bumps
Monday 09:00 UTC → DIUN sends digest change notifications
```
1. Check ntfy for DIUN notifications and Gitea for Renovate PRs
2. Review and merge Renovate PRs (CI auto-deploys)
3. For `:latest` tag updates (no version to bump), redeploy the stack via Portainer
### Updating a Single Service (Step-by-Step)
**Method 1: Portainer Redeploy (simplest, recommended for `:latest` tags)**
1. Open Portainer: https://192.168.0.200:9443
2. Go to Stacks → select the stack
3. Click **Pull and redeploy** (or **Update the stack** → check "Re-pull image")
4. Verify the container is healthy after redeploy
Or via Portainer API:
```bash
# Redeploy a GitOps stack (pulls latest from git + pulls images)
curl -sk -X PUT "https://192.168.0.200:9443/api/stacks/<STACK_ID>/git/redeploy?endpointId=2" \
-H "X-API-Key: "REDACTED_API_KEY" \
-H "Content-Type: application/json" \
-d '{"pullImage": true, "prune": true, "repositoryAuthentication": true, "repositoryUsername": "vish", "repositoryPassword": "<GITEA_TOKEN>"}'
```
Or via MCP (from opencode/Claude Code):
```
redeploy_stack("sonarr-stack")
```
**Method 2: Git commit (recommended for version-pinned images)**
```bash
# 1. Edit the compose file
vim hosts/synology/atlantis/arr-suite/docker-compose.yml
# Change: image: linuxserver/sonarr:4.0.0
# To: image: linuxserver/sonarr:4.1.2
# 2. Commit and push
git add hosts/synology/atlantis/arr-suite/docker-compose.yml
git commit -m "feat: update sonarr to 4.1.2"
git push
# 3. CI auto-deploys within ~30 seconds via portainer-deploy.yml
```
**Method 3: Watchtower (emergency — updates ALL containers on a host)**
```bash
curl -X POST http://192.168.0.200:8083/v1/update \
-H "Authorization: Bearer watchtower-metrics-token"
```
Use sparingly — this pulls and recreates every container on the host.
### Updating All Services on a Host
```bash
# Trigger Watchtower on the host
curl -X POST http://<host-ip>:8083/v1/update \
-H "Authorization: Bearer watchtower-metrics-token"
# Or redeploy all stacks via Portainer API
# (the portainer-deploy CI does this automatically on git push)
```
### Verifying an Update
After any update method, verify the container is healthy:
```bash
# Via MCP
list_stack_containers("sonarr-stack")
check_url("http://192.168.0.200:8989")
# Via CLI
ssh atlantis "/usr/local/bin/docker ps --filter name=sonarr --format '{{.Names}}: {{.Image}} ({{.Status}})'"
```
## Gotchas
### Orphan Containers After Manual `docker compose up`
If you run `docker compose up` directly on a host (not through Portainer), the containers get a different compose project label than the Portainer-managed stack. This creates:
- A "Limited" ghost entry in the Portainer Stacks UI
- Redeploy failures: "container name already in use"
**Fix:** Stop and remove the orphaned containers, then redeploy via Portainer.
**Prevention:** Always update through Portainer (UI, API, or GitOps CI). Never run `docker compose up` directly for Portainer-managed stacks.
### Git Auth Failures on Redeploy
If a stack redeploy returns "authentication required", the Gitea credentials cached in the stack are stale. Pass the service account token in the redeploy request (see Method 1 above).
## Image Tagging Strategy
| Strategy | Used By | Pros | Cons |
|----------|---------|------|------|
| `:latest` | Most services | Always newest, simple | Can break, no rollback, Renovate can't bump |
| `:version` (e.g., `:4.1.2`) | Critical services | Deterministic, Renovate can bump | Requires manual/Renovate updates |
| `:major` (e.g., `:4`) | Some LinuxServer images | Auto-updates within major | May get breaking minor changes |
**Recommendation:** Use specific version tags for critical services (Plex, Sonarr, Radarr, Authentik, Gitea, PostgreSQL). Use `:latest` for non-critical/replaceable services (IT-Tools, theme-park, iperf3).
## Services That CANNOT Be GitOps Deployed
These two services are **bootstrap dependencies** for the GitOps pipeline itself. They must be managed manually via `docker compose` or through Portainer UI — never through the CI/CD workflow.
| Service | Host | Reason |
|---------|------|--------|
| **Gitea** | Calypso | Hosts the git repository. CI/CD pulls code from Gitea, so auto-deploying Gitea via CI creates a chicken-and-egg problem. If Gitea goes down during a redeploy, the pipeline can't recover. |
| **Nginx Proxy Manager** | matrix-ubuntu | Routes all HTTPS traffic including `git.vish.gg`. Removing NPM to recreate it as a GitOps stack kills access to Gitea, which prevents the GitOps stack from being created. |
**To update these manually:**
```bash
# Gitea
ssh calypso
cd /volume1/docker/gitea
sudo /var/packages/REDACTED_APP_PASSWORD/target/usr/bin/docker compose pull
sudo /var/packages/REDACTED_APP_PASSWORD/target/usr/bin/docker compose up -d
# Nginx Proxy Manager
ssh matrix-ubuntu
cd /opt/npm
sudo docker compose pull
sudo docker compose up -d
```
## Services NOT Auto-Updated
These services should be updated manually with care:
| Service | Reason |
|---------|--------|
| **Gitea** | Bootstrap dependency (see above) |
| **Nginx Proxy Manager** | Bootstrap dependency on matrix-ubuntu (see above) |
| **Authentik** | SSO provider — broken update locks out all services |
| **PostgreSQL** | Database — major version upgrades require migration |
| **Portainer** | Container orchestrator — update via DSM or manual Docker commands |
## Monitoring Update Status
```bash
# Check which images are outdated (via DIUN ntfy topic)
# Subscribe to: https://ntfy.vish.gg/diun
# Check Watchtower metrics
curl http://192.168.0.200:8083/v1/metrics \
-H "Authorization: Bearer watchtower-metrics-token"
# Check running image digests vs remote
docker images --digests | grep <image-name>
```

# Homelab MCP Server Guide
The homelab MCP (Model Context Protocol) server gives Claude Code live access to homelab infrastructure. Instead of copying logs or running curl commands manually, Claude can query and act on real systems directly in the conversation.
## What is MCP?
MCP is a standard that lets Claude connect to external tools and services as "plugins". Each MCP server exposes a set of tools. When Claude is connected to the homelab MCP server, it can call those tools mid-conversation to get live data or take actions.
**Flow:** You ask Claude something → Claude calls an MCP tool → Tool hits a real API → Claude answers with live data.
## Server Location
```
scripts/homelab-mcp/server.py
```
Single Python file using [FastMCP](https://github.com/jlowin/fastmcp). No database, no daemon, no background threads — it only runs while Claude Code is active.

## How Claude Code Connects
The MCP server is registered in Claude Code's project settings:
```json
// .claude/settings.local.json
{
"mcpServers": {
"homelab": {
"command": "python3",
"args": ["scripts/homelab-mcp/server.py"]
}
}
}
```
When you open Claude Code in this repo directory, the MCP server starts automatically. You can verify it's working by asking Claude to list endpoints or check Portainer.
## Resource Usage
The server is a single Python process that starts on-demand. It consumes:
- **Memory:** ~30–50MB while running
- **CPU:** Near zero (only active during tool calls)
- **Network:** Minimal — one API call per tool invocation
No background polling, no persistent connections.
## Adding New Tools
1. Add a helper function (e.g. `_myservice(...)`) at the top of `server.py`
2. Add config constants in the Configuration section
3. Decorate tool functions with `@mcp.tool()`
4. Add a section to this doc
The FastMCP framework auto-generates the tool schema from the function signature and docstring. Args are described in the docstring `Args:` block.

# Operational Notes & Known Issues
*Last Updated: 2026-01-26*
This document contains important operational notes, known issues, and fixes for the homelab infrastructure.
---
## Server-Specific Notes
### Concord NUC (100.72.55.21)
#### Node Exporter
- **Runs on bare metal** (not containerized)
- Port: 9100
- Prometheus scrapes successfully from `100.72.55.21:9100`
- Do NOT deploy containerized node_exporter - it will conflict with the host service
#### Watchtower
- Requires `DOCKER_API_VERSION=1.44` environment variable
- This is because the Portainer Edge Agent uses an older Docker API version
- Without this env var, watchtower fails with: `client version 1.25 is too old`
#### Invidious
- Health check reports "unhealthy" but the application works fine
- The health check calls `/api/v1/trending` which returns HTTP 500
- This is a known upstream issue with YouTube's API changes
- **Workaround**: Ignore the unhealthy status or modify the health check endpoint

## Deployment Architecture
### Git-Linked Stacks
- Most stacks are deployed from Gitea (`git.vish.gg/Vish/homelab`)
- Branch: `wip`
- Portainer pulls configs directly from the repo
- Changes to repo configs will affect deployed stacks on next redeploy/update
### Standalone Containers
The following containers are managed directly in Portainer (NOT Git-linked):
- `portainer` / `portainer_edge_agent` - Infrastructure
- `watchtower` - Auto-updates (on some servers)
- `node-exporter` containers (where not bare metal)
- Various testing/temporary containers
### Bare Metal Services
Some services run directly on hosts, not in containers:
- **Concord NUC**: node_exporter (port 9100)
---
## Common Issues & Solutions
### Issue: Watchtower restart loop on Edge Agent hosts
**Symptom**: Watchtower continuously restarts with API version error
**Cause**: Portainer Edge Agent uses older Docker API
**Solution**: Add `DOCKER_API_VERSION=1.44` to watchtower container environment
### Issue: Port 9100 already in use for node_exporter container
**Symptom**: Container fails to start, "address already in use"
**Cause**: node_exporter running on bare metal
**Solution**: Don't run containerized node_exporter; use the bare metal instance
### Issue: Invidious health check failing
**Symptom**: Container shows "unhealthy" but works fine
**Cause**: YouTube API changes causing /api/v1/trending to return 500
**Solution**: This is cosmetic; the app works. Consider updating health check endpoint.
---
## Maintenance Checklist
- [ ] Check Prometheus targets regularly for DOWN status
- [ ] Monitor watchtower logs for update failures
- [ ] Review Portainer for containers in restart loops
- [ ] Keep Git repo configs in sync with running stacks
- [ ] Document any manual container changes in this file

## 📋 Overview
This guide covers how to interact with the Portainer API for managing the homelab infrastructure, including GitOps deployments, container management, and system monitoring.
## 🔗 API Access Information
### Primary Portainer Instance
- **URL**: https://192.168.0.200:9443
- **API Endpoint**: https://192.168.0.200:9443/api
- **Version**: 2.39.0 (Portainer Enterprise Edition)
- **Instance ID**: dc043e05-f486-476e-ada3-d19aaea0037d
### Authentication
Portainer supports two authentication methods:
**Option A — API Access Token (recommended):**
```bash
# Tokens starting with ptr_ use the X-API-Key header (NOT Bearer)
export PORTAINER_TOKEN="<your-portainer-api-token>"
curl -k -H "X-API-Key: $PORTAINER_TOKEN" https://192.168.0.200:9443/api/stacks
```
**Option B — JWT (username/password):**
```bash
TOKEN=$(curl -k -s -X POST https://192.168.0.200:9443/api/auth \
-H "Content-Type: application/json" \
-d '{"Username":"admin","Password":"YOUR_PASSWORD"}' | jq -r '.jwt')
curl -k -H "Authorization: Bearer $TOKEN" https://192.168.0.200:9443/api/stacks
```
> **Note:** `ptr_` API tokens must use `X-API-Key`, not `Authorization: Bearer`.
> Using `Bearer` with a `ptr_` token returns `{"message":"Invalid JWT token"}`.
### Endpoint IDs
| Endpoint | ID |
|---|---|
| Atlantis | 2 |
| Calypso | 443397 |
| Concord NUC | 443398 |
| Homelab VM | 443399 |
| RPi5 | 443395 |
## 🚀 GitOps Management
### Check GitOps Stack Status
```bash
# List all stacks with Git config
curl -k -s -H "X-API-Key: $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/stacks | \
jq '[.[] | select(.GitConfig.URL) | {id:.Id, name:.Name, status:.Status, file:.GitConfig.ConfigFilePath, credId:.GitConfig.Authentication.GitCredentialID}]'
# Get specific stack details
curl -k -H "X-API-Key: $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/stacks/{stack_id}
```
### Trigger GitOps Deployment
```bash
# Redeploy stack from Git (pass creds inline to bypass saved credential cache)
curl -k -X PUT -H "X-API-Key: $PORTAINER_TOKEN" \
-H "Content-Type: application/json" \
"https://192.168.0.200:9443/api/stacks/{stack_id}/git/redeploy?endpointId={endpoint_id}" \
-d '{"pullImage":true,"prune":false,"repositoryAuthentication":true,"repositoryUsername":"vish","repositoryPassword":"YOUR_GITEA_TOKEN"}'
```
### Manage Git Credentials
```bash
# The saved Git credential used by most stacks is "portainer-homelab" (credId: 1)
# List saved credentials:
curl -k -s -H "X-API-Key: $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/users/1/gitcredentials | jq '.'
# Update the saved credential (e.g. after rotating the Gitea token):
curl -k -s -X PUT \
-H "X-API-Key: $PORTAINER_TOKEN" \
-H "Content-Type: application/json" \
"https://192.168.0.200:9443/api/users/1/gitcredentials/1" \
-d '{"name":"portainer-homelab","username":"vish","password":"YOUR_NEW_GITEA_TOKEN"}'
```
### Scan Containers for Broken Credentials
```bash
# Useful after a sanitization commit — finds any REDACTED values in running container envs
python3 << 'EOF'
import json, urllib.request, ssl
ctx = ssl.create_default_context(); ctx.check_hostname = False; ctx.verify_mode = ssl.CERT_NONE
token = "REDACTED_TOKEN"
base = "https://192.168.0.200:9443/api"
endpoints = {"atlantis":2,"calypso":443397,"nuc":443398,"homelab":443399,"rpi5":443395}
def api(p):
req = urllib.request.Request(f"{base}{p}", headers={"X-API-Key": token})
with urllib.request.urlopen(req, context=ctx) as r: return json.loads(r.read())
for ep_name, ep_id in endpoints.items():
for c in api(f"/endpoints/{ep_id}/docker/containers/json?all=true"):
info = api(f"/endpoints/{ep_id}/docker/containers/{c['Id'][:12]}/json")
hits = [e for e in (info.get("Config",{}).get("Env") or []) if "REDACTED" in e]
if hits: print(f"[{ep_name}] {c['Names'][0]}"); [print(f" {h}") for h in hits]
EOF
```

# Get Portainer metrics (if enabled)
curl -k -H "Authorization: Bearer $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/endpoints/1/docker/containers/json | \
jq '[.[] | {name: .Names[0], state: .State, status: .Status}]'
```
### Alerting Integration
```bash
# Check for unhealthy containers
UNHEALTHY=$(curl -k -s -H "Authorization: Bearer $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/endpoints/1/docker/containers/json | \
jq -r '.[] | select(.State != "running") | .Names[0]')
if [[ -n "$UNHEALTHY" ]]; then
echo "⚠️ Unhealthy containers detected:"
echo "$UNHEALTHY"
fi
```
## 🔐 Security Best Practices
### API Token Management
- **Rotation**: Rotate API tokens regularly (monthly)
- **Scope**: Use least-privilege tokens when possible
- **Storage**: Store tokens securely (environment variables, secrets management)
### Network Security
- **TLS**: Always use HTTPS endpoints
- **Firewall**: Restrict API access to authorized networks
- **Monitoring**: Log all API access for security auditing
## 🚨 Troubleshooting
### Common Issues
#### Authentication Failures
```bash
# Check token validity
curl -k -H "Authorization: Bearer $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/users/me
```
#### Connection Issues
```bash
# Test basic connectivity
curl -k -s https://192.168.0.200:9443/api/status
# Check certificate issues
openssl s_client -connect 192.168.0.200:9443 -servername atlantis.vish.local
```
#### GitOps Sync Issues
```bash
# Check stack deployment logs
curl -k -H "Authorization: Bearer $PORTAINER_TOKEN" \
https://192.168.0.200:9443/api/stacks/{stack_id}/logs
```

# Portainer vs Dockhand — Analysis & Recommendation
*Assessed: March 2026 | Portainer Business Edition 2.39.0 LTS | Dockhand v1.0.20*
---
## 1. Context — How This Homelab Uses Portainer
This homelab runs **Portainer Business Edition** as its container management platform across 5 hosts and ~81 stacks (~157 containers total). It is important to understand the *actual* usage pattern before evaluating alternatives:
**What Portainer is used for here:**
- **Deployment target** — the CI workflow (`portainer-deploy.yml`) calls Portainer's REST API to deploy stack updates; Portainer is the endpoint, not the engine
- **Container UI** — logs, exec, resource view, per-host visibility, container lifecycle
- **Stack inventory** — single pane of glass across all 5 hosts
**What Portainer's built-in GitOps is NOT used for:**
Portainer's own GitOps polling/webhook engine is largely bypassed. The custom CI workflow handles all of:
- Detecting changed files via git diff
- Classifying stacks (GitOps vs detached vs string)
- Injecting secrets at deploy time
- Path translation between legacy and canonical paths
- Notifications via ntfy
This distinction matters: most GitOps-related complaints about Portainer CE don't apply here because those features aren't being relied upon.
---
## 2. Portainer Business Edition — Current State
### Version
**2.39.0 LTS** — the latest stable release as of February 2026. ✅
### Key bugs fixed in recent releases relevant to this setup
| Fix | Version |
|-----|---------|
| GitOps removing containers when image pull fails (data-loss bug) | 2.39.0 |
| Webhook URLs regenerating unexpectedly on stack edits | 2.37.0 |
| Stack update button silently doing nothing | 2.33.4, 2.37.0 |
| CSRF "Origin invalid" error behind reverse proxy | 2.33.0+ |
### Pain points still present (despite BE license)
| Issue | Impact |
|-------|--------|
| Non-root compose path bug (Portainer 2.39 ignores `composeFilePathInRepository`) | Forces `atlantis-arr-stack` and `derper-atl` into "string stack" workaround in CI |
| 17+ stacks reference legacy `Atlantis/` / `Calypso/` symlink paths | Requires path translation logic in CI workflow |
| GUI "Pull and Redeploy" always fails | By design — credentials are injected by CI only, never saved in Portainer |
| `#11015`: GitOps polling silently breaks if stack creator account is deleted | Low risk (single-user setup) but worth knowing |
| No git submodule support | Not currently needed but worth noting |
### BE features available (that CE users lack)
Since you're on Business Edition, these are already unlocked and relevant:
| Feature | Relevance |
|---------|-----------|
| **Relative path volumes** | Eliminates the need for string stack workarounds — compose files can use `./config:/app/config` sourced from the repo. Worth evaluating for `atlantis-arr-stack` migration. |
| **Shared Git credentials** | Credentials defined once, reusable across stacks — reduces per-stack credential management |
| **Image update notifications** | In-UI indicator when a newer image tag is available |
| **Activity + auth logs** | Audit trail for all API and UI actions |
| **GitOps change windows** | Restrict auto-deploys to specific time windows (maintenance windows) |
| **Fleet Governance Policies** | Policy-based management across environments (added 2.37–2.39) |
| **Force redeployment toggle** | Redeploy even when no Git change detected |
---
## 3. Dockhand — What It Is
**GitHub:** https://github.com/Finsys/dockhand
**Launched:** December 2025 (solo developer, Jarek Krochmalski)
**Stars:** ~3,100 | **Open issues:** ~295 | **Latest:** v1.0.20 (Mar 3 2026)
Dockhand is a modern Docker management UI built as a direct Portainer alternative. It is positioned at the homelab/self-hosted market with a clean SvelteKit UI, Git-first stack deployment, and a lighter architectural footprint.
### Key features
- Git-backed stack deployment with webhook and auto-sync
- Real-time logs (full ANSI color), interactive terminal, in-container file browser
- Multi-host via **Hawser agent** (outbound-only connections — no inbound firewall rules needed)
- Vulnerability scanning (Trivy + Grype integration)
- Image auto-update per container
- OIDC/SSO, MFA in free tier
- SQLite (default) or PostgreSQL backend
### Notable gaps
- **No Docker Swarm support** (not planned)
- **No Kubernetes support**
- **RBAC is Enterprise/paid tier**
- **LDAP/AD is Enterprise/paid tier**
- **Mobile UI** is not responsive-friendly
- **~295 open issues** on a 3-month-old project — significant for production use
- **No proven migration path** from Portainer
### Licensing
**Business Source License 1.1 (BSL 1.1)** — source-available, converts to Apache 2.0 on January 1, 2029.
Effectively free for personal/homelab use with no practical restrictions. Not OSI-approved open source.
---
## 4. Comparison Table
| Dimension | Portainer BE 2.39 | Dockhand v1.0 |
|---|---|---|
| Age / maturity | 9 years, battle-tested | 3 months, early adopter territory |
| Proven at 80+ stacks | Yes | Unknown |
| Migration effort | None (already running) | High — 81 stacks re-registration |
| GitOps quality | Buggy built-in, but CI bypasses it | First-class design, also has bugs |
| UI/UX | Functional, aging | Modern, better DX |
| Multi-host | Solid, agent-based | Solid, Hawser agent (outbound-only) |
| Relative path volumes | Yes (BE) | Yes |
| Shared credentials | Yes (BE) | N/A (per-stack only) |
| RBAC | Yes (BE) | Enterprise/paid tier only |
| Audit logging | Yes (BE) | Enterprise/paid tier only |
| OIDC/SSO | Yes (BE) | Yes (free tier) |
| Docker Swarm | Yes | No |
| Kubernetes | Yes (BE) | No |
| Open issue risk | Low (known issues, slow-moving) | High (295 open, fast-moving target) |
| License | Commercial (BE) | BSL 1.1 → Apache 2.0 2029 |
| Production risk | Low | High |
---
## 5. Recommendation
### Now: Stay on Portainer BE 2.39.0
You are already on the latest LTS with the worst bugs fixed. The BE license means the main CE pain points (relative path volumes, shared credentials, audit logs) are already available — many of the reasons people leave Portainer CE don't apply here.
The custom CI workflow already handles everything Dockhand's GitOps would replace, and it is battle-tested across 81 stacks.
**One concrete improvement available now:** The non-root compose path bug forces `atlantis-arr-stack` into the string stack workaround in CI. Since BE includes relative path volumes, it may be worth testing whether a proper GitOps stack with `composeFilePathInRepository` set works correctly on 2.39.0 — the bug was reported against CE and may behave differently in BE.
### In ~6 months: Reassess Dockhand
Dockhand's architectural direction is better than Portainer's in several ways (outbound-only agents, Git-first design, modern UI). At ~3 months old with 295 open issues it is not a safe migration target for a production 81-stack homelab. Revisit when the criteria below are met.
### Dockhand revisit criteria
Watch for these signals before reconsidering:
- [ ] Open issue count stabilises below ~75–100
- [ ] A named "stable" or LTS release exists (not just v1.0.x incrementing weekly)
- [ ] Portainer → Dockhand migration tooling exists (stack import from Portainer API)
- [ ] 6+ months of no breaking regressions reported in `r/selfhosted` or GitHub
- [ ] RBAC available without Enterprise tier (or confirmed single-user use case is unaffected)
- [ ] Relative volume path / host data dir detection bugs are resolved

# Repository Sanitization
This document describes the sanitization process used to create a safe public mirror of the private homelab repository.
## Overview
The `.gitea/sanitize.py` script automatically removes sensitive information before pushing content to the public repository ([homelab-optimized](https://git.vish.gg/Vish/homelab-optimized)). This ensures that while the public repo contains useful configuration examples, no actual secrets, passwords, or private keys are exposed.
## How It Works
The sanitization script runs as part of the [Mirror to Public Repository](../.gitea/workflows/mirror-to-public.yaml) GitHub Actions workflow. It performs three main operations:
1. **Remove sensitive files completely** - Files containing only secrets are deleted
2. **Remove entire directories** - Directories that shouldn't be public are deleted
3. **Redact sensitive patterns** - Searches and replaces secrets in file contents
## Files Removed Completely
The following categories of files are completely removed from the public mirror:
| Category | Examples |
|----------|----------|
| Private keys/certificates | `.pem` private keys, WireGuard configs |
| Environment files | `.env` files with secrets |
| Token files | API token text files |
| CI/CD workflows | `.gitea/` directory |
### Specific Files Removed
- `hosts/synology/atlantis/matrix_synapse_docs/turn_cert/privkey.pem`
- `hosts/synology/atlantis/matrix_synapse_docs/turn_cert/RSA-privkey.pem`
- `hosts/synology/atlantis/matrix_synapse_docs/turn_cert/ECC-privkey.pem`
- `hosts/edge/nvidia_shield/wireguard/*.conf`
- `hosts/synology/atlantis/jitsi/.env`
- `hosts/synology/atlantis/matrix_synapse_docs/turnserver.conf`
- `.gitea/` directory (entire CI/CD configuration)
## Redacted Patterns
The script searches for and redacts the following types of sensitive data:
### Passwords
- Generic `password`, `PASSWORD`, `PASSWD` values
- Service-specific passwords (Jitsi, SNMP, etc.)
### API Keys & Tokens
- Portainer tokens (`ptr_...`)
- OpenAI API keys (`sk-...`)
- Cloudflare API tokens
- Generic API keys and secrets
- JWT secrets and private keys
### Authentication
- WireGuard private keys
- Authentik secrets and passwords
- Matrix/Synapse registration secrets
- OAuth client secrets
### Personal Information
- Personal email addresses replaced with examples
- SSH public key comments
### Database Credentials
- PostgreSQL/MySQL connection strings with embedded passwords
## Replacement Values
All sensitive data is replaced with descriptive placeholder text:
| Original | Replacement |
|----------|-------------|
| Passwords | `REDACTED_PASSWORD` |
| API Keys | `REDACTED_API_KEY` |
| Tokens | `REDACTED_TOKEN` |
| Private Keys | `REDACTED_PRIVATE_KEY` |
| Email addresses | `your-email@example.com` |
## Files Skipped
The following file types are not processed (binary files, etc.):
- Images (`.png`, `.jpg`, `.jpeg`, `.gif`, `.ico`, `.svg`)
- Fonts (`.woff`, `.woff2`, `.ttf`, `.eot`)
- Git metadata (`.git/` directory)
## Running Sanitization Manually
To run the sanitization script locally:
```bash
cd /path/to/homelab
python3 .gitea/sanitize.py
```
The script will:
1. Remove sensitive files
2. Remove sensitive directories
3. Sanitize file contents across the entire repository
## Verification
After sanitization, you can verify the public repository contains no secrets by:
1. Searching for common secret patterns:
```bash
grep -r "password\s*=" --include="*.yml" --include="*.yaml" --include="*.env" .
grep -r "sk-" --include="*.yml" --include="*.yaml" .
grep -r "REDACTED" .
```
2. Checking that `.gitea/` directory is not present
3. Verifying no `.env` files with secrets exist
## Public Repository
The sanitized public mirror is available at:
- **URL**: https://git.vish.gg/Vish/homelab-optimized
- **Purpose**: Share configuration examples without exposing secrets
- **Update Frequency**: Automatically synced on every push to main branch
## Troubleshooting
### Sensitive Data Still Appearing
If you find sensitive data in the public mirror:
1. Add the file to `FILES_TO_REMOVE` in `sanitize.py`
2. Add a new regex pattern to `SENSITIVE_PATTERNS`
3. Run the workflow manually to re-push
### False Positives
If legitimate content is being redacted incorrectly:
1. Identify the pattern causing the issue
2. Modify the regex to be more specific
3. Test locally before pushing

# AI Integrations
**Last updated:** 2026-03-20
Overview of all AI/LLM integrations across the homelab. The primary GPU inference backend is **Olares** (RTX 5090 Max-Q, 24GB VRAM) running Qwen3-Coder via Ollama.
---
## Primary AI Backend — Olares
| Property | Value |
|----------|-------|
| **Host** | Olares (`192.168.0.145`) |
| **GPU** | RTX 5090 Max-Q (24GB VRAM) |
| **Active model** | `qwen3:32b` (30.5B MoE, Q4_K_M) |
| **Ollama endpoint** | `https://a5be22681.vishinator.olares.com` |
| **OpenAI-compat endpoint** | `https://a5be22681.vishinator.olares.com/v1` |
| **Native Ollama API** | `https://a5be22681.vishinator.olares.com/api/...` |
> Port 11434 is not directly exposed — all access goes through the Olares reverse proxy at the above URL.
### Check active models
```bash
curl -s https://a5be22681.vishinator.olares.com/api/tags | python3 -m json.tool
curl -s https://a5be22681.vishinator.olares.com/api/ps # currently loaded in VRAM
```
### Switch models
See `docs/services/individual/olares.md` for scaling operations.
---
## Services Using Olares AI
| Service | Host | Feature | Config |
|---------|------|---------|--------|
| **AnythingLLM** | Atlantis | RAG document assistant | `LLM_PROVIDER=generic-openai`, `GENERIC_OPEN_AI_BASE_PATH=https://a5be22681.vishinator.olares.com/v1`, model=`qwen3:32b` |
| **Perplexica** | homelab-vm | AI-powered search engine | `OLLAMA_BASE_URL=https://a5be22681.vishinator.olares.com`, model set via UI |
| **Reactive Resume v5** | Calypso | AI resume writing assistance | `OPENAI_BASE_URL=https://a5be22681.vishinator.olares.com/v1`, model=`qwen3:32b` |
| **OpenCode (homelab-vm)** | homelab-vm | Coding agent | `~/.config/opencode/opencode.json` → Olares Ollama, model=`qwen3:32b` |
| **OpenCode (moon)** | moon | Coding agent | `/home/moon/.config/opencode/opencode.json` → Olares Ollama, model=`qwen3:32b` (was: vLLM `qwen3-30b` — migrated 2026-03-20) |
### Perplexica config persistence
Perplexica stores its provider config in a Docker volume at `/home/perplexica/data/config.json`. The `OLLAMA_BASE_URL` env var sets the default but the UI/DB config takes precedence. The current config is set to `olares-ollama` provider with `qwen3:32b`.
To reset if the config gets corrupted:
```bash
docker exec perplexica cat /home/perplexica/data/config.json
# Edit and update as needed, then restart
docker restart perplexica
```
---
## Services Using Other AI Backends
| Service | Host | Backend | Notes |
|---------|------|---------|-------|
| **OpenHands** | homelab-vm | Anthropic Claude Sonnet 4 (cloud) | `LLM_MODEL=anthropic/claude-sonnet-4-20250514` — kept on Claude as it's significantly better for agentic coding than local models |
| **Paperless-AI** | Calypso | LM Studio on Shinku (`100.98.93.15:1234`) via Tailscale | Auto-tags/classifies Paperless documents. Model: `llama-3.2-3b-instruct`. Could be switched to Olares for better quality. |
| **Hoarder** | homelab-vm | OpenAI cloud API (`sk-proj-...`) | AI bookmark tagging/summarization. Could be switched to Olares to save cost. |
| **Home Assistant Voice** | Concord NUC | Local Whisper `tiny-int8` + Piper TTS | Voice command pipeline — fully local, no GPU needed |
| **Ollama + Open WebUI** | Atlantis | ROCm GPU (`phi3:mini`, `gemma:2b`) | Separate Ollama instance for Atlantis-local use |
| **LlamaGPT** | Atlantis | llama.cpp (`Nous-Hermes-Llama-2-7B`) | Legacy — likely unused |
| **Reactive Resume (bundled)** | Calypso | Bundled Ollama `Resume-OLLAMA-V5` (`llama3.2:3b`) | Still running but app is now pointed at Olares |
| **Ollama + vLLM** | Seattle VPS | CPU-only (`llama3.2:3b`, `Qwen2.5-1.5B`) | CPU inference, used previously by Perplexica |
| **OpenHands (MSI laptop)** | Edge device | LM Studio (`devstral-small-2507`) | Ad-hoc run config, not a managed stack |
---
## Candidates to Migrate to Olares
| Service | Effort | Benefit |
|---------|--------|---------|
| **Paperless-AI** | Low — change `CUSTOM_BASE_URL` in compose | Better model (30B vs 3B) for document classification |
| **Hoarder** | Low — add `OPENAI_BASE_URL` env var | Eliminates cloud API cost |
---
## Olares Endpoint Reference
| Protocol | URL | Use for |
|----------|-----|---------|
| OpenAI-compat (Ollama) | `https://a5be22681.vishinator.olares.com/v1` | Services expecting OpenAI API format — **primary endpoint** |
| Native Ollama | `https://a5be22681.vishinator.olares.com` | Services with native Ollama support |
| Models list | `https://a5be22681.vishinator.olares.com/api/tags` | Check available models |
| Active models | `https://a5be22681.vishinator.olares.com/api/ps` | Check VRAM usage |
| vLLM (legacy) | `https://04521407.vishinator.olares.com/v1` | vLLM inference — available but not currently used |
> **Note:** Only one large model should be loaded at a time (24GB VRAM limit). If inference is slow or failing, check `api/ps` — another model may be occupying VRAM.
### OpenCode per-host config
OpenCode config lives at `~/.config/opencode/opencode.json` on each machine. All instances use Olares Ollama:
```json
{
"$schema": "https://opencode.ai/config.json",
"provider": {
"olares": {
"npm": "@ai-sdk/openai-compatible",
"name": "Olares Ollama (Qwen3-Coder)",
"options": {
"baseURL": "https://a5be22681.vishinator.olares.com/v1"
},
"models": {
"qwen3:32b": {
"name": "Qwen3 Coder 30.5B Q4_K_M",
"limit": { "context": 40000, "output": 8192 }
}
}
}
},
"model": "olares/qwen3:32b"
}
```
Config locations:
- **homelab-vm**: `/home/homelab/.config/opencode/opencode.json`
- **moon**: `/home/moon/.config/opencode/opencode.json` (migrated from vLLM 2026-03-20)

# 🚨 Alerting & Notification System
**Last Updated**: 2026-01-27
This document describes the homelab alerting stack that provides dual-channel notifications via **ntfy** (mobile push) and **Signal** (encrypted messaging).
---
## Overview
The alerting system monitors your infrastructure and sends notifications through two channels:
| Channel | Use Case | App Required |
|---------|----------|--------------|
| **ntfy** | All alerts (warnings + critical) | ntfy iOS/Android app |
| **Signal** | Critical alerts only | Signal messenger |
### Alert Severity Routing
```
⚠️ Warning alerts → ntfy only
🚨 Critical alerts → ntfy + Signal
✅ Resolved alerts → Both channels (for critical)
```
---
## Architecture
```

## Configuration Files
### Alertmanager Configuration
```yaml
# ~/docker/monitoring/alerting/alertmanager/alertmanager.yml
global:
resolve_timeout: 5m
route:
group_by: ['alertname', 'severity', 'instance']
group_wait: 30s
group_interval: 5m

- url: 'http://ntfy-bridge:5001/alert'
send_resolved: true
- url: 'http://signal-bridge:5000/alert'
send_resolved: true
```
### Docker Compose (Alerting Stack)
```yaml
# ~/docker/monitoring/alerting/docker-compose.alerting.yml
services:
alertmanager:
image: prom/alertmanager:latest
container_name: alertmanager
ports:
- "9093:9093"

environment:
- SIGNAL_API_URL=http://signal-api:8080
- SIGNAL_SENDER=+REDACTED_PHONE_NUMBER
- SIGNAL_RECIPIENTS=+REDACTED_PHONE_NUMBER
networks:
- monitoring-stack_default
- signal-api-stack_default
```
---
## iOS ntfy Configuration
For iOS push notifications to work with self-hosted ntfy, the upstream proxy must be configured:
```yaml
# ~/docker/ntfy/config/server.yml
base-url: "https://ntfy.vish.gg"
upstream-base-url: "https://ntfy.sh"
```
This routes iOS notifications through ntfy.sh's APNs integration while keeping messages on your self-hosted server.
---
## Testing Notifications
### Test ntfy Alert
```bash
curl -X POST http://localhost:5001/alert -H "Content-Type: application/json" -d '{
"alerts": [{
"status": "firing",
"labels": {"alertname": "TestAlert", "severity": "warning", "instance": "test:9100"},
"annotations": {"summary": "Test alert", "description": "This is a test notification"}
}]
}'
```
### Test Signal Alert
```bash
curl -X POST http://localhost:5000/alert -H "Content-Type: application/json" -d '{
"alerts": [{
"status": "firing",
"labels": {"alertname": "TestAlert", "severity": "critical", "instance": "test:9100"},
"annotations": {"summary": "Test alert", "description": "This is a test notification"}
}]
}'
```
### Test Direct ntfy
```bash
curl -H "Title: Test" -d "Hello from homelab!" https://ntfy.vish.gg/REDACTED_NTFY_TOPIC
```
---
## Troubleshooting
### Alerts not firing
1. Check Prometheus targets: http://homelab-vm:9090/targets
2. Check alert rules: http://homelab-vm:9090/alerts
3. Check Alertmanager: http://homelab-vm:9093
### ntfy notifications not received on iOS
1. Verify `upstream-base-url: "https://ntfy.sh"` is set
2. Restart ntfy container: `docker restart NTFY`
3. Re-subscribe in iOS app
### Signal notifications not working
1. Check signal-api is registered: `docker logs signal-api`
2. Verify phone number is linked
3. Test signal-bridge health: `curl http://localhost:5000/health`
---

**Not backed up (re-downloadable):**
- `/mnt/data/jellyfin` (203 GB), `/mnt/data/llama` (64 GB), `/mnt/data/iso` (556 MB)
**Not yet backed up (manual add):**
- `/mnt/data/guava_turquoise` (3 TB) — see instructions below
**Manual commands:**
```bash
# Backup
sudo restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password \
backup /mnt/data/photos /mnt/data/cocalc /mnt/data/medical \
/mnt/data/website /mnt/data/openproject /mnt/data/fasten
# List snapshots
sudo restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password snapshots
# Verify integrity
sudo restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password check
# Restore (full)
sudo restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password \
restore latest --target /mnt/data/restore
# Restore specific path
sudo restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password \
restore latest --target /tmp/restore --include "/mnt/data/medical"
# Prune old snapshots
sudo restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password \
forget --keep-daily 7 --keep-weekly 4 --keep-monthly 3 --prune
```
### Adding guava_turquoise to the backup
From a `root@guava` shell, follow these steps to add `/mnt/data/guava_turquoise` (3 TB) to the existing B2 backup.
**1. Run a one-time backup of guava_turquoise (initial upload ~25 hrs at 30 MB/s):**
```bash
restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password \
-o rclone.args="serve restic --stdio --b2-hard-delete --transfers 16" \
backup /mnt/data/guava_turquoise
```
**2. Verify the snapshot was created:**
```bash
restic -r rclone:b2:vk-guava/restic \
--password-file /root/.restic-password \
snapshots
```
**3. Update the daily cron job to include guava_turquoise going forward:**
```bash
midclt call cronjob.query
```
Find the cron job ID (currently 1), then update it:
```bash
midclt call cronjob.update 1 '{
"command": "restic -r rclone:b2:vk-guava/restic --password-file /root/.restic-password -o rclone.args=\"serve restic --stdio --b2-hard-delete --transfers 16\" backup /mnt/data/photos /mnt/data/cocalc /mnt/data/medical /mnt/data/website /mnt/data/openproject /mnt/data/fasten /mnt/data/fenrus /mnt/data/passionfruit /mnt/data/guava_turquoise && restic -r rclone:b2:vk-guava/restic --password-file /root/.restic-password -o rclone.args=\"serve restic --stdio --b2-hard-delete --transfers 16\" forget --keep-daily 7 --keep-weekly 4 --keep-monthly 3 --prune"
}'
```
**4. Verify the cron job was updated:**
```bash
midclt call cronjob.query
```
**5. (Optional) Trigger the cron job immediately instead of waiting for 3 AM:**
```bash
midclt call cronjob.run 1
```
**Cost impact:** guava_turquoise adds ~$15/mo to B2 storage (at $5/TB). After the initial upload, daily incrementals will only upload changes.
---
## Portainer Backup (vk-portainer)
Automated daily backups of all Portainer stack configurations:
- **Format**: Encrypted `.tar.gz` archives
- **Retention**: Hide after 30 days, delete after 31 days
- **Source**: Portainer backup API on homelab VM
- **Destination**: `vk-portainer` bucket
---
## Checking Bucket Status
```bash
# Via B2 native API
curl -s -u "$B2_KEY_ID:$B2_APP_KEY" \
https://api.backblazeb2.com/b2api/v3/b2_authorize_account
# Via AWS CLI (S3-compatible)
source ~/.b2_env
aws s3 ls --endpoint-url https://s3.us-west-004.backblazeb2.com
aws s3 ls s3://vk-atlantis/ --endpoint-url https://s3.us-west-004.backblazeb2.com --recursive | sort | tail -20
```
---
## Rotation Policy Changes (2026-03-21)
| Host | Before | After |
|------|--------|-------|
| **Atlantis** | rotate_earliest, max 256 versions | Smart Recycle, max 30 versions |
| **Setillo** | rotate_earliest, max 256 versions | Smart Recycle, max 30 versions |
| **Calypso** | Smart Recycle, max 7 versions | No change |
Old versions will be pruned automatically by Hyper Backup on next scheduled run.
---
## Notes
- All active buckets use `us-west-004` region (Backblaze B2)
- Hyper Backup on Synology hosts handles encryption before upload
- Guava uses restic (AES-256 encryption) — password stored in `/root/.restic-password`
- `vk-games` is a **public** bucket — consider making it private or deleting if unused
- `vk-setillo` has **no data encryption** — only transit encryption
- B2 API key is stored in `~/.b2_env` and is compatible with AWS CLI S3 API
- The `sanitize.py` script redacts B2 credentials before public repo mirroring

# Backup Plan — Decision Document
> **Status**: Planning — awaiting decisions on open questions before implementation
> **Last updated**: 2026-03-13
> **Related**: [backup-strategies.md](backup-strategies.md) (aspirational doc, mostly not yet deployed)
---
## Current State (Honest)
| What | Status |
|---|---|
| Synology Hyper Backup (Atlantis → Calypso) | ✅ Running, configured in DSM GUI |
| Synology Hyper Backup (Atlantis → Setillo) | ✅ Running, configured in DSM GUI |
| Syncthing docker config sync (Atlantis/Calypso/Setillo) | ✅ Running |
| Synology snapshots for media volumes | ✅ Adequate — decided, no change needed |
| Scheduled database backups | ❌ Not deployed (Firefly sidecar is the only exception) |
| Docker volume backups for non-Synology hosts | ❌ Not deployed |
| Cloud (Backblaze B2) | ❌ Account exists, nothing uploading yet |
| Unified backup monitoring / alerting | ❌ Not deployed |
The migration scripts (`backup-matrix.sh`, `backup-mastodon.sh`, `backup.sh`) are
one-off migration artifacts — not scheduled, not monitored.
---
## Recommended Tool: Borgmatic
Borgmatic wraps BorgBackup (deduplicated, encrypted, compressed backups) with a
single YAML config file that handles scheduling, database hooks, and alerting.
| Concern | How Borgmatic addresses it |
|---|---|
| Deduplication | BorgBackup — only changed chunks stored; daily full runs are cheap |
| Encryption | AES-256 at rest, passphrase-protected repo |
| Database backups | Native `postgresql_databases` and `mysql_databases` hooks — calls pg_dump/mysqldump before each run, streams output into the Borg repo |
| Scheduling | Built-in cron expression in config, or run as a container with the `borgmatic-cron` image |
| Alerting | Native ntfy / healthchecks.io / email hooks — fires on failure |
| Restoration | `borgmatic extract` or direct `borg extract` — well-documented |
| Complexity | Low — one YAML file per host, one Docker container |
### Why not the alternatives
| Tool | Reason not chosen |
|---|---|
| Restic | No built-in DB hooks, no built-in scheduler — needs cron + wrapper scripts |
| Kopia | Newer, less battle-tested at this scale; no native DB hooks |
| Duplicati | Unstable history of bugs; no DB hooks; GUI-only config |
| rclone | Sync tool, not a backup tool — no dedup, no versioning, no DB hooks |
| Raw rsync | No dedup, no encryption, no DB hooks, fragile for large trees |
Restic is the closest alternative and would be acceptable if Borgmatic hits issues,
but Borgmatic's native DB hooks are the deciding factor.

## Proposed Architecture
### What to back up per host
**Atlantis** (primary NAS, highest value — do first)
- `/volume2/metadata/docker2/` — all container config/data dirs (~194GB used)
- Databases via hooks:
- `immich-db` (PostgreSQL) — photo metadata
- `vaultwarden` (SQLite) — passwords, via pre-hook tar
- `sonarr`, `radarr`, `prowlarr`, `bazarr`, `lidarr` (SQLite) — via pre-hook
- `tdarr` (SQLite + JSON) — transcode config
- `/volume1/data/media/` — **covered by Synology snapshots, excluded from Borg**
**Calypso** (secondary NAS)
- `/volume1/docker/` — all container config/data dirs
- Databases via hooks:
- `paperless-db` (PostgreSQL)
- `authentik-db` (PostgreSQL)
- `immich-db` (PostgreSQL, Calypso instance)
- `seafile-db` (MySQL)
- `gitea-db` (PostgreSQL) — see open question #5 below
**homelab-vm** (this machine, `100.67.40.126`)
- Docker named volumes — scrutiny, ntfy, syncthing, archivebox, openhands, hoarder, monitoring stack
- Mostly config-weight data, no large databases
**NUC (concord)**
- Docker named volumes — homeassistant, adguard, syncthing, invidious
**Pi-5**
- Docker named volumes — uptime-kuma (SQLite), glances, diun
**Setillo (Seattle VM)** — lower priority, open question (see below)
---
## Options — Borg Repo Destination
All hosts need a repo to write to. Three options:
### Option A — Atlantis as central repo host (simplest)
```
Atlantis (local) → /volume1/backups/borg/atlantis/
Calypso → SSH → Atlantis:/volume1/backups/borg/calypso/
homelab-vm → SSH → Atlantis:/volume1/backups/borg/homelab-vm/
NUC → SSH → Atlantis:/volume1/backups/borg/nuc/
Pi-5 → SSH → Atlantis:/volume1/backups/borg/rpi5/
```
Pros:
- Atlantis already gets Hyper Backup → Calypso + rsync → Setillo, so all Borg
repos get carried offsite for free with no extra work
- Single place to manage retention policies
- 46TB free on Atlantis — ample room
Cons:
- Atlantis is a single point of failure for all repos
### Option B — Atlantis ↔ Calypso cross-backup (more resilient)
```
Atlantis → SSH → Calypso:/volume1/backups/borg/atlantis/
Calypso → SSH → Atlantis:/volume1/backups/borg/calypso/
Other hosts → Atlantis (same as Option A)
```
Pros:
- If Atlantis dies completely, Calypso independently holds Atlantis's backup
- True cross-backup between the two most critical hosts
Cons:
- Two SSH trust relationships to set up and maintain
- Calypso Borg repo would not be on Atlantis, so it doesn't get carried to Setillo
via the existing Hyper Backup job unless the job is updated to include it
### Option C — Local repo per host, then push to Atlantis
- Each host writes a local repo first, then pushes to Atlantis
- Adds a local copy for fast restores without SSH
- Doubles storage use on each host
- Probably unnecessary given Synology's local snapshot coverage on Atlantis/Calypso
**Recommendation: Option A** if simplicity is the priority; **Option B** if you want
Atlantis and Calypso to be truly independent backup failure domains.
---
## Options — Backblaze B2
B2 account exists. The question is what to push there.
### Option 1 — Borg repos via rclone (recommended)
```
Atlantis (weekly cron):
rclone sync /volume1/backups/borg/ b2:homelab-borg/
```
- BorgBackup's chunk-based dedup means only new/changed chunks upload each week
- Estimated size: initial ~50–200GB (configs + DBs only, media excluded), then small incrementals
- rclone runs as a container or cron job on Atlantis after the daily Borg runs complete
- Cost at B2 rates ($0.006/GB/month): ~$1–1.20/month for 200GB
### Option 2 — DB dumps only to B2
- Simpler — just upload the daily pg_dump files
- No dedup — each upload is a full dump
- Less efficient at scale but trivially easy to implement
### Option 3 — Skip B2 for now
- Setillo offsite rsync is sufficient for current risk tolerance
- Add B2 once monitoring is in place and Borgmatic is proven stable
**Recommendation: Option 1** — the dedup makes it cheap and the full Borg repo in B2
means any host can be restored from cloud without needing Setillo to be online.
---
## Open Questions
These must be answered before implementation starts.
### 1. Which hosts to cover?
- [ ] Atlantis
- [ ] Calypso
- [ ] homelab-vm
- [ ] NUC
- [ ] Pi-5
- [ ] Setillo (Seattle VM)
### 2. Borg repo destination
- [ ] Option A: Atlantis only (simplest)
- [ ] Option B: Atlantis ↔ Calypso cross-backup (more resilient)
- [ ] Option C: Local first, then push to Atlantis
### 3. B2 scope
- [ ] Option 1: Borg repos via rclone (recommended)
- [ ] Option 2: DB dumps only
- [ ] Option 3: Skip for now
### 4. Secrets management
Borgmatic configs need: Borg passphrase, SSH private key (to reach Atlantis repo),
B2 app key (if B2 enabled).
Option A — **Portainer env vars** (consistent with rest of homelab)
- Passphrase injected at deploy time, never in git
- SSH keys stored as host-mounted files, path referenced in config
Option B — **Files on host only**
- Drop secrets to e.g. `/volume1/docker/borgmatic/secrets/` per host
- Mount read-only into borgmatic container
- Nothing in git, nothing in Portainer
Option C — **Ansible vault**
- Encrypt secrets in git — fully tracked and reproducible
- More setup overhead
- [ ] Option A: Portainer env vars
- [ ] Option B: Files on host only
- [ ] Option C: Ansible vault
### 5. Gitea chicken-and-egg
CI runs on Gitea. If Borgmatic on Calypso backs up `gitea-db` and Calypso/Gitea
goes down, restoring Gitea is a manual procedure outside of CI — which is acceptable.
The alternative is to exclude `gitea-db` from Borgmatic and back it up separately
(e.g. a simple daily pg_dump cron on Calypso that Hyper Backup then carries).
- [ ] Include gitea-db in Borgmatic (manual restore procedure documented)
- [ ] Exclude from Borgmatic, use separate pg_dump cron
### 6. Alerting ntfy topic
Borgmatic can push failure alerts to the existing ntfy stack on homelab-vm.
- [ ] Confirm ntfy topic name to use (e.g. `homelab-backups` or `homelab`)
- [ ] Confirm ntfy internal URL (e.g. `http://100.67.40.126:<port>`)
---
## Implementation Phases (draft, not yet started)
Once decisions above are made, implementation follows these phases in order:
**Phase 1 — Atlantis**
1. Create `hosts/synology/atlantis/borgmatic.yaml`
2. Config: backs up `/volume2/metadata/docker2`, DB hooks for all postgres/sqlite containers
3. Repo destination per decision on Q2
4. Alert on failure via ntfy
**Phase 2 — Calypso**
1. Create `hosts/synology/calypso/borgmatic.yaml`
2. Config: backs up `/volume1/docker`, DB hooks for paperless/authentik/immich/seafile/(gitea)
3. Repo: SSH to Atlantis (or cross-backup per Q2)
**Phase 3 — homelab-vm, NUC, Pi-5**
1. Create borgmatic stack per host
2. Mount `/var/lib/docker/volumes` read-only into container
3. Repos: SSH to Atlantis
4. Staggered schedule: 02:00 Atlantis / 03:00 Calypso / 04:00 homelab-vm / 04:30 NUC / 05:00 Pi-5
**Phase 4 — B2 cloud egress** (if Option 1 or 2 chosen)
1. Add rclone container or cron on Atlantis
2. Weekly sync of Borg repos → `b2:homelab-borg/`
**Phase 5 — Monitoring**
1. Borgmatic ntfy hook per host — fires on any failure
2. Uptime Kuma push monitor per host — borgmatic pings after each successful run
3. Alert if no ping received in 25h

## 🗃️ Database Backups
### PostgreSQL Automated Backup
```bash
#!/bin/bash
# backup-postgres.sh
BACKUP_DIR="/volume1/backups/databases"
DATE=$(date +%Y%m%d_%H%M%S)
RETENTION_DAYS=14
# List of database containers to backup
DATABASES=(
"immich-db:immich"
"paperless-db:paperless"
"vaultwarden-db:vaultwarden"
"mastodon-db:mastodon_production"
)
for db_info in "${DATABASES[@]}"; do
CONTAINER="${db_info%%:*}"
DATABASE="${db_info##*:}"
echo "Backing up $DATABASE from $CONTAINER..."
docker exec "$CONTAINER" pg_dump -U postgres "$DATABASE" | \
gzip > "$BACKUP_DIR/${DATABASE}_${DATE}.sql.gz"
# Verify backup
if [ $? -eq 0 ]; then
echo "✓ $DATABASE backup successful"
else
echo "✗ $DATABASE backup FAILED"
# Send alert
curl -d "Database backup failed: $DATABASE" ntfy.sh/homelab-alerts
fi
done
# Clean old backups
find "$BACKUP_DIR" -name "*.sql.gz" -mtime +$RETENTION_DAYS -delete
echo "Database backup complete"
```
### MySQL/MariaDB Backup
```bash
#!/bin/bash
# backup-mysql.sh
BACKUP_DIR="/volume1/backups/databases"
DATE=$(date +%Y%m%d_%H%M%S)
# Backup MariaDB
docker exec mariadb mysqldump -u root -p"$MYSQL_ROOT_PASSWORD" \
--all-databases | gzip > "$BACKUP_DIR/mariadb_${DATE}.sql.gz"
```
### Schedule with Cron
```bash
# /etc/crontab or Synology Task Scheduler
# Daily at 2 AM
0 2 * * * /volume1/scripts/backup-postgres.sh >> /var/log/backup.log 2>&1
# Weekly integrity check
0 4 * * 0 /volume1/scripts/verify-backups.sh >> /var/log/backup.log 2>&1
```
---
## 🐳 Docker Volume Backups
### Backup All Named Volumes
```bash
#!/bin/bash
# backup-docker-volumes.sh
BACKUP_DIR="/volume1/backups/docker-volumes"
DATE=$(date +%Y%m%d)
# Get all named volumes
VOLUMES=$(docker volume ls -q)
for volume in $VOLUMES; do
echo "Backing up volume: $volume"
docker run --rm \
-v "$volume":/source:ro \
-v "$BACKUP_DIR":/backup \
alpine tar czf "/backup/${volume}_${DATE}.tar.gz" -C /source .
done
# Clean old backups (keep 7 days)
find "$BACKUP_DIR" -name "*.tar.gz" -mtime +7 -delete
```
### Restore Docker Volume
```bash
#!/bin/bash
# restore-docker-volume.sh
VOLUME_NAME="$1"
BACKUP_FILE="$2"
# Create volume if not exists
docker volume create "$VOLUME_NAME"
# Restore from backup
docker run --rm \
-v "$VOLUME_NAME":/target \
-v "$(dirname "$BACKUP_FILE")":/backup:ro \
alpine tar xzf "/backup/$(basename "$BACKUP_FILE")" -C /target
```
---
## ☁️ Cloud Backup (Backblaze B2)
### Setup with Rclone
```bash
# Install rclone
curl https://rclone.org/install.sh | sudo bash
# Configure B2
rclone config
# Choose: New remote
# Name: b2
# Type: Backblaze B2
# Account ID: <your-account-id>
# Application Key: <your-app-key>
```
### Backup Script
```bash
#!/bin/bash
# backup-to-b2.sh
BUCKET="homelab-backups"
SOURCE="/volume1/backups"
# Sync with encryption
rclone sync "$SOURCE" "b2:$BUCKET" \
--crypt-remote="b2:$BUCKET" \
--crypt-password="REDACTED_PASSWORD" /root/.rclone-password)" \
--transfers=4 \
--checkers=8 \
--bwlimit=50M \
--log-file=/var/log/rclone-backup.log \
--log-level=INFO
# Verify sync
rclone check "$SOURCE" "b2:$BUCKET" --one-way
```
### Cost Estimation
```
Backblaze B2 Pricing:
- Storage: $0.005/GB/month
- Downloads: $0.01/GB (first 1GB free daily)
Example (500GB backup):
- Monthly storage: 500GB × $0.005 = $2.50/month
- Annual: $30/year
Recommended for:
- Photos (Immich): ~500GB
- Documents (Paperless): ~50GB
- Critical configs: ~10GB
```
---
## 🔐 Vaultwarden Backup
### Automated Vaultwarden Backup
```bash
#!/bin/bash
# backup-vaultwarden.sh
BACKUP_DIR="/volume1/backups/vaultwarden"
DATE=$(date +%Y%m%d_%H%M%S)
CONTAINER="vaultwarden"
# Stop container briefly for consistent backup
docker stop "$CONTAINER"
# Backup data directory
tar czf "$BACKUP_DIR/vaultwarden_${DATE}.tar.gz" \
-C /volume1/docker/vaultwarden .
# Restart container
docker start "$CONTAINER"
# Keep only last 30 backups
ls -t "$BACKUP_DIR"/vaultwarden_*.tar.gz | tail -n +31 | xargs -r rm
# Also create encrypted export for offline access
# (Requires admin token)
curl -X POST "http://localhost:8080/admin/users/export" \
-H "Authorization: Bearer $VAULTWARDEN_ADMIN_TOKEN" \
-o "$BACKUP_DIR/vaultwarden_export_${DATE}.json"
# Encrypt the export
gpg --symmetric --cipher-algo AES256 \
-o "$BACKUP_DIR/vaultwarden_export_${DATE}.json.gpg" \
"$BACKUP_DIR/vaultwarden_export_${DATE}.json"
rm "$BACKUP_DIR/vaultwarden_export_${DATE}.json"
echo "Vaultwarden backup complete"
```
---
## 📸 Immich Photo Backup
### External Library Backup Strategy
```yaml
# Immich backup approach:
# 1. Original photos stored on Atlantis
# 2. Syncthing replicates to Calypso (real-time)
# 3. Hyper Backup to Setillo (weekly)
# 4. Optional: rclone to B2 (monthly)
backup_paths:
originals: /volume1/photos/library
database: /volume1/docker/immich/postgres
thumbnails: /volume1/docker/immich/thumbs # Can be regenerated
```
### Database-Only Backup (Fast)
```bash
#!/bin/bash
# Quick Immich database backup (without photos)
docker exec immich-db pg_dump -U postgres immich | \
gzip > /volume1/backups/immich_db_$(date +%Y%m%d).sql.gz
```
---
## ✅ Backup Verification
### Automated Verification Script
```bash
#!/bin/bash
# verify-backups.sh
BACKUP_DIR="/volume1/backups"
ALERT_URL="ntfy.sh/homelab-alerts"
ERRORS=0
echo "=== Backup Verification Report ==="

if [ $ERRORS -eq 0 ]; then
echo "All backup checks passed ✓"
else
echo "$ERRORS backup check(s) FAILED ✗"
curl -d "Backup verification failed: $ERRORS errors" "$ALERT_URL"
fi
```
### Test Restore Procedure
```bash
#!/bin/bash
# test-restore.sh - Monthly restore test
TEST_DIR="/volume1/restore-test"
mkdir -p "$TEST_DIR"
# Test PostgreSQL restore
echo "Testing PostgreSQL restore..."
LATEST_DB=$(ls -t /volume1/backups/databases/immich_*.sql.gz | head -1)
docker run --rm \
-v "$TEST_DIR":/restore \
-v "$LATEST_DB":/backup.sql.gz:ro \
postgres:15 \
bash -c "gunzip -c /backup.sql.gz | psql -U postgres"
# Verify tables exist
if docker exec test-postgres psql -U postgres -c "\dt" | grep -q "assets"; then
echo "✓ PostgreSQL restore verified"
else
echo "✗ PostgreSQL restore failed"
fi
# Cleanup
rm -rf "$TEST_DIR"
```

# Credential Rotation Checklist
**Last audited**: March 2026
**Purpose**: Prioritized list of credentials that should be rotated, with exact locations and steps.
> After rotating any credential, update it in **Vaultwarden** (collection: Homelab) as the source of truth before updating the compose file or Portainer stack.
---
## Priority Legend
| Symbol | Meaning |
|--------|---------|
| 🔴 CRITICAL | Live credential exposed in git — rotate immediately |
| 🟠 HIGH | Sensitive secret that should be rotated soon |
| 🟡 MEDIUM | Lower-risk but should be updated as part of routine rotation |
| 🟢 LOW | Default/placeholder values — change before putting service in production |
---
## 🔴 CRITICAL — Rotate Immediately
### 1. OpenAI API Key
- **File**: `hosts/vms/homelab-vm/hoarder.yaml:15`
- **Service**: Hoarder AI tagging
- **Rotation steps**:
1. Go to [platform.openai.com/api-keys](https://platform.openai.com/api-keys)
2. Delete the old key
3. Create a new key
4. Update `hosts/vms/homelab-vm/hoarder.yaml` — `OPENAI_API_KEY`
5. Save new key in Vaultwarden → Homelab → Hoarder
6. Redeploy hoarder stack via Portainer
### 2. Gmail App Password — Authentik + Joplin SMTP (see Vaultwarden → Homelab → Gmail App Passwords)
- **Files**:
- `hosts/synology/calypso/authentik/docker-compose.yaml` (SMTP password)
- `hosts/synology/atlantis/joplin.yml` (SMTP password)
- **Rotation steps**:
1. Go to [myaccount.google.com/apppasswords](https://myaccount.google.com/apppasswords)
2. Revoke the old app password
3. Create a new app password (label: "Homelab SMTP")
4. Update both files above with the new password
5. Save in Vaultwarden → Homelab → Gmail App Passwords
6. Redeploy both stacks
### 3. Gmail App Password — Vaultwarden SMTP (see Vaultwarden → Homelab → Gmail App Passwords)
- **File**: `hosts/synology/atlantis/vaultwarden.yaml`
- **Rotation steps**: Same as above — create a separate app password per service
1. Revoke old, create new
2. Update `hosts/synology/atlantis/vaultwarden.yaml` — `SMTP_PASSWORD`
3. Redeploy vaultwarden stack
### 4. Gmail App Password — Documenso SMTP (see Vaultwarden → Homelab → Gmail App Passwords)
- **File**: `hosts/synology/atlantis/documenso/documenso.yaml:47`
- **Rotation steps**: Same pattern — revoke, create new, update compose, redeploy
### 5. Gmail App Password — Reactive Resume SMTP (see Vaultwarden → Homelab → Gmail App Passwords)
- **File**: `hosts/synology/calypso/reactive_resume_v5/docker-compose.yml`
- **Rotation steps**: Same pattern
### 6. Gitea PAT — retro-site.yaml (now removed)
- **Status**: ✅ Hardcoded token removed from `retro-site.yaml` — now uses `${GIT_TOKEN}` env var
- **Action**: Revoke the old token `REDACTED_GITEA_TOKEN` in Gitea
1. Go to `https://git.vish.gg/user/settings/applications`
2. Revoke the token associated with `retro-site.yaml`
3. The stack now uses the `GIT_TOKEN` Gitea secret — no file update needed
### 7. Gitea PAT — Ansible Playbook (now removed)
- **Status**: ✅ Hardcoded token removed from `ansible/automation/playbooks/setup_gitea_runner.yml`
- **Action**: Revoke the old token `REDACTED_GITEA_TOKEN` in Gitea
1. Go to `https://git.vish.gg/user/settings/applications`
2. Revoke the associated token
3. Future runs of the playbook will prompt for the token interactively
---
## 🟠 HIGH — Rotate Soon
### 8. Authentik Secret Key
- **File**: `hosts/synology/calypso/authentik/docker-compose.yaml:58,89`
- **Impact**: Rotating this invalidates **all active sessions** — do during a maintenance window
- **Rotation steps**:
1. Generate a new 50-char random key: `openssl rand -base64 50`
2. Update `AUTHENTIK_SECRET_KEY` in the compose file
3. Save in Vaultwarden → Homelab → Authentik
4. Redeploy — all users will need to re-authenticate
### 9. Mastodon SECRET_KEY_BASE + OTP_SECRET
- **File**: `hosts/synology/atlantis/mastodon.yml:67-68`
- **Impact**: Rotating breaks **all active sessions and 2FA tokens** — coordinate with users
- **Rotation steps**:
1. Generate new values:
```bash
docker run --rm tootsuite/mastodon bundle exec rake secret
docker run --rm tootsuite/mastodon bundle exec rake secret
```
2. Update `SECRET_KEY_BASE` and `OTP_SECRET` in `mastodon.yml`
3. Save in Vaultwarden → Homelab → Mastodon
4. Redeploy
### 10. Grafana OAuth Client Secret (Authentik Provider)
- **File**: `hosts/vms/homelab-vm/monitoring.yaml:986`
- **Rotation steps**:
1. Go to Authentik → Applications → Providers → Grafana provider
2. Edit → regenerate client secret
3. Copy the new secret
4. Update `GF_AUTH_GENERIC_OAUTH_CLIENT_SECRET` in `monitoring.yaml`
5. Save in Vaultwarden → Homelab → Grafana OAuth
6. Redeploy monitoring stack
---
## 🟡 MEDIUM — Routine Rotation
### 11. Watchtower HTTP API Token (`REDACTED_WATCHTOWER_TOKEN`)
- **Files** (must update all at once):
- `hosts/synology/atlantis/watchtower.yml`
- `hosts/synology/atlantis/grafana_prometheus/prometheus.yml`
- `hosts/synology/atlantis/grafana_prometheus/prometheus_mariushosting.yml`
- `hosts/synology/calypso/grafana_prometheus/prometheus.yml`
- `hosts/synology/setillo/prometheus/prometheus.yml`
- `hosts/synology/calypso/watchtower.yaml`
- `common/watchtower-enhanced.yaml`
- `common/watchtower-full.yaml`
- **Rotation steps**:
1. Choose a new token: `openssl rand -hex 32`
2. Update `WATCHTOWER_HTTP_API_TOKEN` in all watchtower stack files
3. Update `bearer_token` in all prometheus.yml scrape configs
4. Save in Vaultwarden → Homelab → Watchtower
5. Redeploy all affected stacks (watchtower first, then prometheus)
### 12. Shlink API Key
- **File**: `hosts/vms/homelab-vm/shlink.yml:41`
- **Rotation steps**:
1. Log into Shlink admin UI
2. Generate a new API key
3. Update `DEFAULT_API_KEY` in `shlink.yml`
4. Save in Vaultwarden → Homelab → Shlink
5. Redeploy shlink stack
### 13. Spotify Client ID + Secret (YourSpotify)
- **Files**:
- `hosts/physical/concord-nuc/yourspotify.yaml`
- `hosts/vms/bulgaria-vm/yourspotify.yml`
- **Rotation steps**:
1. Go to [developer.spotify.com/dashboard](https://developer.spotify.com/dashboard)
2. Select the app → Settings → Rotate client secret
3. Update both files with new `SPOTIFY_CLIENT_ID` and `SPOTIFY_CLIENT_SECRET`
4. Save in Vaultwarden → Homelab → Spotify API
5. Redeploy both stacks
### 14. SNMPv3 Auth + Priv Passwords
- **Files**:
- `hosts/synology/atlantis/grafana_prometheus/snmp.yml` (exporter config)
- `hosts/vms/homelab-vm/monitoring.yaml` (prometheus scrape config)
- **Note**: Must match the SNMPv3 credentials configured on the target devices (Synology NAS, switches)
- **Rotation steps**:
1. Change the SNMPv3 user credentials on each monitored device (DSM → Terminal & SNMP)
2. Update `auth_password` and `priv_password` in `snmp.yml`
3. Update the corresponding values in `monitoring.yaml`
4. Save in Vaultwarden → Homelab → SNMP
5. Redeploy monitoring stack
---
## 🟢 LOW — Change Before Production Use
These are clearly placeholder/default values that exist in stacks but are either:
- Not currently deployed in production, or
- Low-impact internal-only services
| Service | File | Credential | Value to Replace |
|---------|------|-----------|-----------------|
| NetBox | `hosts/synology/atlantis/netbox.yml` | Superuser password | see Vaultwarden |
| Paperless | `hosts/synology/calypso/paperless/docker-compose.yml` | Admin password | see Vaultwarden |
| Seafile | `hosts/synology/calypso/seafile-server.yaml` | Admin password | see Vaultwarden |
| Gotify | `hosts/vms/homelab-vm/gotify.yml` | Admin password | `REDACTED_PASSWORD` |
| Invidious (old) | `hosts/physical/concord-nuc/invidious/invidious_old/invidious.yaml` | PO token | Rotate if service is active |
---
## Post-Rotation Checklist
After rotating any credential:
- [ ] New value saved in Vaultwarden under correct collection/folder
- [ ] Compose file updated in git repo
- [ ] Stack redeployed via Portainer (or `docker compose up -d --force-recreate`)
- [ ] Service verified healthy (check Uptime Kuma / Portainer logs)
- [ ] Old credential revoked at the source (Google, OpenAI, Gitea, etc.)
- [ ] `.secrets.baseline` updated if detect-secrets flags the new value:
```bash
detect-secrets scan --baseline .secrets.baseline
git add .secrets.baseline && git commit -m "chore: update secrets baseline after rotation"
```

# 🚀 Service Deployment Guide
**🟡 Intermediate Guide**
This guide covers how to deploy new services in the homelab infrastructure, following established patterns and best practices used across all 176 Docker Compose configurations.
## 🎯 Deployment Philosophy
### 🏗️ **Infrastructure as Code**
- All services are defined in Docker Compose files
- Configuration is version-controlled in Git
- Ansible automates deployment and management
- Consistent patterns across all services
### 🔄 **Deployment Workflow**
```
Development → Testing → Staging → Production
↓ ↓ ↓ ↓
Local PC → Test VM → Staging → Live Host
```
---
## 📋 Pre-Deployment Checklist
### ✅ **Before You Start**
- [ ] Identify the appropriate host for your service
- [ ] Check resource requirements (CPU, RAM, storage)
- [ ] Verify network port availability
- [ ] Review security implications
- [ ] Plan data persistence strategy
- [ ] Consider backup requirements
### 🎯 **Host Selection Criteria**

- /tmp
- /var/tmp
# Capability dropping
cap_drop:
- ALL
cap_add:
- CHOWN # Only add what's needed
```
### 🔑 **Secrets Management**
```yaml
# Use Docker secrets for sensitive data
secrets:
db_password:
"REDACTED_PASSWORD" ./secrets/db_password.txt
services:
app:
secrets:
- db_password
environment:
- DB_PASSWORD_FILE=/run/secrets/db_password
```
### 🌐 **Network Security**
```yaml
# Custom networks for isolation
networks:
frontend:
internal: false # Internet access
backend:
internal: true # No internet access
services:
web:
networks:
- frontend
- backend
database:
networks:
- backend # Database isolated from internet
```
---
## 📊 Monitoring Integration
### 📈 **Health Checks**
```yaml
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
interval: 30s
timeout: 10s
retries: 3
start_period: 60s
```
### 🏷️ **Prometheus Labels**
```yaml
labels:
- "prometheus.io/scrape=true"
- "prometheus.io/port=8080"
- "prometheus.io/path=/metrics"
- "service.category=media"
- "service.tier=production"
```
### 📊 **Logging Configuration**

docker-compose down
# Edit configuration files
docker-compose up -d
# Rolling updates (zero downtime)
docker-compose up -d --no-deps service-name
```
### 🗄️ **Database Migrations**
```bash
# Backup before migration
docker exec db-container pg_dump -U user dbname > backup.sql
# Run migrations
docker-compose exec app python manage.py migrate
# Verify migration
docker-compose exec app python manage.py showmigrations
```
---
## 📊 Performance Optimization
### ⚡ **Resource Tuning**
```yaml
# Optimize for your workload
deploy:
resources:
limits:
memory: 2G # Set based on actual usage
cpus: '1.0' # Adjust for CPU requirements

memory: 512M # Guarantee minimum resources
```
### 🗄️ **Storage Optimization**
```yaml
# Use appropriate volume types
volumes:
# Fast storage for databases
- /volume1/ssd/db:/var/lib/postgresql/data
# Slower storage for archives
- /volume1/hdd/archives:/archives:ro
# Temporary storage
- type: tmpfs

## 🔄 Failover Procedures
### Host-Level Failover
1. Identify primary host failure
2. Deploy stack to alternative host
3. Validate access via Tailscale
4. Update DNS if needed (Cloudflare)
5. Confirm service availability from external access
### Network-Level Failover
1. Switch traffic routing via Cloudflare
2. Update DNS records for affected services
3. Test connectivity from multiple sources
4. Monitor service health in Uptime Kuma
5. Document routing changes
## ⚠️ Known Limitations
### Unbacked Data
- **Jellyfish (RPi 5)**: Photos-only backup, no cloud sync
- **Homelab VM**: Monitoring databases are stateless and rebuildable
- **Concord NUC**: Small config files that can be regenerated
### Recovery Dependencies
- Some services require Tailscale access for proper operation
- External DNS resolution depends on Cloudflare being operational
- Backup restoration assumes sufficient disk space is available

# GitOps Deployment Guide
This guide explains how to apply the fixed dashboard configurations to the production GitOps monitoring stack.
## 🎯 Overview
The production monitoring stack is deployed via **Portainer GitOps** on `homelab-vm` and automatically syncs from this repository. The configuration is embedded in `hosts/vms/homelab-vm/monitoring.yaml`.
## 🔧 Applying Dashboard Fixes
### Current Status
- **Production GitOps**: Uses embedded dashboard configs (may have datasource UID issues)
- **Development Stack**: Has all fixes applied (`docker/monitoring/`)
### Step-by-Step Fix Process
#### 1. Test Fixes Locally
```bash
# Deploy the fixed development stack
cd docker/monitoring
docker-compose up -d
# Verify all dashboards work
./verify-dashboard-sections.sh
# Access: http://localhost:3300 (admin/admin)
```
#### 2. Extract Fixed Dashboard JSON
```bash
# Get the fixed Synology dashboard
cat docker/monitoring/grafana/dashboards/synology-nas-monitoring.json
# Get other fixed dashboards
cat docker/monitoring/grafana/dashboards/node-exporter-full.json
cat docker/monitoring/grafana/dashboards/node-details.json
cat docker/monitoring/grafana/dashboards/infrastructure-overview.json
```
#### 3. Update GitOps Configuration
Edit `hosts/vms/homelab-vm/monitoring.yaml` and replace the embedded dashboard configs:
```yaml
configs:
# Replace this section with fixed JSON
dashboard_synology:
content: |
{
# Paste the fixed JSON from docker/monitoring/grafana/dashboards/synology-nas-monitoring.json
# Make sure to update the datasource UID to: PBFA97CFB590B2093
}
```
#### 4. Key Fixes to Apply
**Datasource UID Fix:**
```json
"datasource": {
"type": "prometheus",
"uid": "PBFA97CFB590B2093" // ← Ensure this matches your Prometheus UID
}
```
**Template Variable Fix:**
```json
"templating": {
"list": [
{
"current": {
"selected": false,
"text": "All",
"value": "$__all" // ← Ensure proper current value
}
}
]
}
```
**Instance Filter Fix:**
```json
"targets": [
{
"expr": "up{instance=~\"$instance\"}", // ← Fix empty instance filters
"legendFormat": "{{instance}}"
}
]
```
#### 5. Deploy via GitOps
```bash
# Commit the updated configuration
git add hosts/vms/homelab-vm/monitoring.yaml
git commit -m "Fix dashboard datasource UIDs and template variables in GitOps
- Updated Synology NAS dashboard with correct Prometheus UID
- Fixed template variables with proper current values
- Corrected instance filters in all dashboard queries
- Verified fixes work in development stack first
Fixes applied from docker/monitoring/ development stack."
# Push to trigger GitOps deployment
git push origin main
```
#### 6. Verify Production Deployment
1. **Check Portainer**: Monitor the stack update in Portainer
2. **Access Grafana**: https://gf.vish.gg
3. **Test Dashboards**: Verify all panels show data
4. **Check Logs**: Review container logs if issues occur
## 🚨 Rollback Process
If the GitOps deployment fails:
```bash
# Revert the commit
git revert HEAD
# Push the rollback
git push origin main
# Or restore from backup
git checkout HEAD~1 -- hosts/vms/homelab-vm/monitoring.yaml
git commit -m "Rollback monitoring configuration"
git push origin main
```
## 📋 Validation Checklist
Before applying to production:
- [ ] Development stack works correctly (`docker/monitoring/`)
- [ ] All dashboard panels display data
- [ ] Template variables function properly
- [ ] Instance filters are not empty
- [ ] Datasource UIDs match production Prometheus
- [ ] JSON syntax is valid (use `jq` to validate)
- [ ] Backup of current GitOps config exists
## 🔍 Troubleshooting
### Dashboard Shows "No Data"
1. Check datasource UID matches production Prometheus
2. Verify Prometheus is accessible from Grafana container
3. Check template variable queries
4. Ensure instance filters are properly formatted
### GitOps Deployment Fails
1. Check Portainer stack logs
2. Validate YAML syntax in monitoring.yaml
3. Ensure Docker configs are properly formatted
4. Verify git repository connectivity
### Container Won't Start
1. Check Docker Compose syntax
2. Verify config file formatting
3. Check volume mounts and permissions
4. Review container logs for specific errors

- **Portainer access**: Role-based access control
- **Service isolation**: Network segmentation
- **Secrets management**: External secret storage
### Security Scanning
```yaml
# Security scanning in CI/CD pipeline
security_scan:
stage: security
script:
- docker run --rm -v $(pwd):/app clair-scanner:latest
- trivy fs --security-checks vuln,config .
- hadolint Dockerfile
```
### Network Security
```yaml
# Network isolation
networks:
frontend:
driver: bridge
internal: false
backend:
driver: bridge
internal: true
database:
driver: bridge
internal: true
```
## Backup and Recovery
### Configuration Backup
```bash
# Backup Portainer configuration
docker exec portainer tar -czf /backup/portainer-config-$(date +%Y%m%d).tar.gz /data
# Backup Git repository
git clone --mirror https://git.vish.gg/Vish/homelab.git /backup/homelab-mirror
```
### Disaster Recovery
1. **Repository restoration**: Clone from backup or remote
2. **Portainer restoration**: Restore configuration and stacks
3. **Service redeployment**: Automatic redeployment from Git
4. **Data restoration**: Restore persistent volumes
5. **Verification**: Comprehensive service testing
### Recovery Testing
```bash
# Regular disaster recovery testing
./scripts/test-disaster-recovery.sh
```
## Troubleshooting
### Common Issues
#### Deployment Failures
```bash
# Check Portainer logs
docker logs portainer
# Verify Git connectivity
git ls-remote https://git.vish.gg/Vish/homelab.git
# Check Docker daemon
docker system info
```
#### Service Health Issues
```bash
# Check container status
docker ps -a
# View service logs
docker logs service-name
# Inspect container configuration
docker inspect service-name
```
#### Network Connectivity
```bash

# 🔄 GitOps with Portainer
**🟡 Intermediate Guide**
This guide covers the GitOps deployment model used to manage all Docker stacks in the homelab. Portainer automatically syncs with the Git repository to deploy and update services.
## 🎯 Overview
### How It Works
```
┌─────────────┐ push ┌─────────────┐ poll (5min) ┌─────────────┐
│ Git Repo │ ◄────────── │ Developer │ │ Portainer │
│ git.vish.gg │ │ │ │ │
└─────────────┘ └─────────────┘ └──────┬──────┘
│ │
│ ─────────────────────────────────────────────────────────────┘
│ fetch changes
▼
┌─────────────────────────────────────────────────────────────────────────┐
│ Docker Hosts (5 endpoints) │
│ ┌──────────┐ ┌──────────┐ ┌──────────┐ ┌──────────┐ ┌──────────┐ │
│ │ Atlantis │ │ Calypso │ │ Concord │ │ Homelab │ │ RPi5 │ │
│ │ NAS │ │ NAS │ │ NUC │ │ VM │ │ │ │
│ └──────────┘ └──────────┘ └──────────┘ └──────────┘ └──────────┘ │
└─────────────────────────────────────────────────────────────────────────┘
```
### Key Components
| Component | URL/Location | Purpose |
|-----------|--------------|---------|
| **Git Repository** | `https://git.vish.gg/Vish/homelab.git` | Source of truth for all configs |
| **Portainer** | `http://vishinator.synology.me:10000` | Stack deployment & management |
| **Branch** | `refs/heads/main` | Production deployment branch |
---
## 📁 Repository Structure
Stacks are organized by host. The canonical paths are under `hosts/`:
```
homelab/
├── hosts/
│ ├── synology/
│ │ ├── atlantis/ # Atlantis NAS stacks ← use this path
│ │ └── calypso/ # Calypso NAS stacks ← use this path
│ ├── physical/
│ │ └── concord-nuc/ # Intel NUC stacks
│ ├── vms/
│ │ └── homelab-vm/ # Proxmox VM stacks
│ └── edge/
│ └── rpi5-vish/ # Raspberry Pi stacks
├── common/ # Shared configs (watchtower, etc.)
│
│ # Legacy symlinks — DO NOT use for new stacks (see note below)
├── Atlantis -> hosts/synology/atlantis
├── Calypso -> hosts/synology/calypso
├── concord_nuc -> hosts/physical/concord-nuc
├── homelab_vm -> hosts/vms/homelab-vm
└── raspberry-pi-5-vish -> hosts/edge/rpi5-vish
```
> **Note on symlinks:** The root-level symlinks (`Atlantis/`, `Calypso/`, etc.) exist only for
> backwards compatibility and as Git-level convenience aliases. All Portainer stacks across every
> endpoint have been migrated to canonical `hosts/` paths as of March 2026.
>
> **Always use the canonical `hosts/…` path when creating new Portainer stacks.**

## ⚙️ Portainer Stack Settings
### GitOps Updates Configuration
Each stack in Portainer has these settings:
| Setting | Recommended | Description |
|---------|-------------|-------------|
| **GitOps updates** | ✅ ON | Enable automatic sync from Git |
| **Mechanism** | Polling | Check Git periodically (vs webhook) |
| **Fetch interval** | `5m` | How often to check for changes |
| **Re-pull image** | ✅ ON* | Pull fresh `:latest` images on deploy |
| **Force redeployment** | ❌ OFF | Only redeploy when files change |
*Enable "Re-pull image" only for stable services using `:latest` tags.
### When Stacks Update
Portainer only redeploys a stack when:
1. The specific compose file for that stack changes in Git
2. A new commit is pushed that modifies the stack's yaml file
**Important**: Commits that don't touch a stack's compose file won't trigger a redeploy for that stack. This is expected behavior - you don't want every stack restarting on every commit.
---
## 🏷️ Image Tag Strategy
### Recommended Tags by Service Type
| Service Type | Tag Strategy | Re-pull Image |
|--------------|--------------|---------------|
| **Monitoring** (node-exporter, glances) | `:latest` | ✅ ON |
| **Utilities** (watchtower, ntfy) | `:latest` | ✅ ON |
| **Privacy frontends** (redlib, proxitok) | `:latest` | ✅ ON |
| **Databases** (postgres, redis) | `:16`, `:7` (pinned) | ❌ OFF |
| **Critical services** (paperless, immich) | `:latest` or pinned | Case by case |
| **Media servers** (plex, jellyfin) | `:latest` | ✅ ON |
### Stacks with Re-pull Enabled
The following stable stacks have "Re-pull image" enabled for automatic updates:
- `glances-stack` (rpi5)
- `uptime-kuma-stack` (rpi5)
- `watchtower-stack` (all hosts)
- `node-exporter-stack` (Calypso, Concord NUC)
- `diun-stack` (all hosts)
- `dozzle-agent-stack` (all hosts)
- `ntfy-stack` (homelab-vm)
- `redlib-stack` (homelab-vm)
- `proxitok-stack` (homelab-vm)
- `monitoring-stack` (homelab-vm)
- `alerting-stack` (homelab-vm)
- `openhands-stack` (homelab-vm)
- `scrutiny-stack` (homelab-vm)
- `scrutiny-collector-stack` (Calypso, Concord NUC)
- `apt-cacher-ng-stack` (Calypso)
- `paperless-stack` (Calypso)
- `paperless-ai-stack` (Calypso)

## 🔧 Managing Stacks
### Adding a New Stack
1. **Create the compose file** in the appropriate host directory:
```bash
cd hosts/synology/calypso/
vim new-service.yaml
```
2. **Commit and push**:
```bash
git add new-service.yaml
git commit -m "Add new-service to Calypso"
git push origin main
```
3. **Create stack in Portainer**:
- Go to Stacks → Add stack
- Select "Repository"
- Repository URL: `https://git.vish.gg/Vish/homelab.git`
- Reference: `refs/heads/main`
- Compose path: `hosts/synology/calypso/new-service.yaml` (always use canonical `hosts/` path)
- Enable GitOps updates with 5m polling
### Updating an Existing Stack
1. **Edit the compose file**:
```bash
vim hosts/synology/calypso/existing-service.yaml
```
2. **Commit and push**:
```bash
git commit -am "Update existing-service configuration"
git push origin main
```
3. **Wait for auto-sync** (up to 5 minutes) or manually click "Pull and redeploy" in Portainer
### Force Immediate Update
In Portainer UI:
1. Go to the stack
2. Click "Pull and redeploy"
3. Optionally enable "Re-pull image" for this deployment
Via API:
```bash
curl -X PUT \
-H "X-API-Key: YOUR_API_KEY" \
"http://vishinator.synology.me:10000/api/stacks/{id}/git/redeploy?endpointId={endpointId}" \
-d '{"pullImage":true,"repositREDACTED_APP_PASSWORD":"refs/heads/main","prune":false}'
```
### Creating a GitOps Stack via API
To create a new GitOps stack from the repository:
```bash
curl -X POST \
-H "X-API-Key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
"http://vishinator.synology.me:10000/api/stacks/create/standalone/repository?endpointId=443399" \
-d '{
"name": "my-new-stack",
"repositoryURL": "https://git.vish.gg/Vish/homelab.git",
"repositREDACTED_APP_PASSWORD": "refs/heads/main",
"composeFile": "hosts/vms/homelab-vm/my-service.yaml",
"repositoREDACTED_APP_PASSWORD": true,
"reREDACTED_APP_PASSWORD": "",
"reREDACTED_APP_PASSWORD": "YOUR_GIT_TOKEN",
"autoUpdate": {
"interval": "5m",
"forceUpdate": false,
"forcePullImage": false
}
}'
```
**Endpoint IDs:**
| Endpoint | ID |
|----------|-----|
| Atlantis | 2 |
| Calypso | 443397 |
| Homelab VM | 443399 |
| RPi5 | 443395 |
| Concord NUC | 443398 |
---
## 📊 Monitoring Sync Status
### Check Stack Versions
Each stack shows its current Git commit hash. Compare with the repo:
```bash
# Get current repo HEAD
git log -1 --format="%H"
# Check in Portainer
# Stack → GitConfig → ConfigHash should match
```
### Common Sync States
| ConfigHash matches HEAD | Stack files changed | Result |
|------------------------|---------------------|--------|
| ✅ Yes | N/A | Up to date |
| ❌ No | ✅ Yes | Will update on next poll |
| ❌ No | ❌ No | Expected - stack unchanged |
### Troubleshooting Sync Issues
**Stack not updating:**
1. Check if the specific compose file changed (not just any file)
2. Verify Git credentials in Portainer are valid
3. Check Portainer logs for fetch errors
4. Try manual "Pull and redeploy"
**Wrong version deployed:**
1. Verify the branch is `refs/heads/main`
2. Check compose file path matches (watch for symlinks)
3. Clear Portainer's git cache by recreating the stack
---
## 🔐 Git Authentication
Stacks use a shared Git credential configured in Portainer:
| Setting | Value |
|---------|-------|
| **Credential ID** | 1 |
| **Repository** | `https://git.vish.gg/Vish/homelab.git` |
| **Auth Type** | Token-based |
To update credentials:
1. Portainer → Settings → Credentials
2. Update the Git credential
3. All stacks using that credential will use the new token
---
## 📋 Best Practices
### Do ✅
- Use descriptive commit messages for stack changes
- Test compose files locally before pushing
- Keep one service per compose file when possible
- Use canonical `hosts/…` paths in Portainer for new stacks (not symlink paths)
- Enable re-pull for stable `:latest` services
### Don't ❌
- Force redeployment (causes unnecessary restarts)
- Use `latest` tag for databases
- Push broken compose files to main
- Manually edit stacks in Portainer (changes will be overwritten)

# MCP Deployment Workflow — End-to-End Example
This shows the complete workflow for deploying a new container using MCP tools, with annotations explaining REDACTED_APP_PASSWORD and why.
**Example service:** Stirling PDF at `pdf.vish.gg` on Atlantis
---
## The Full Workflow
### 1. Check — Does it exist already?
```
MCP: list_containers(endpoint="atlantis", filter_name="stirling")
MCP: cloudflare_list_dns_records(filter_name="pdf")
```
**Why MCP:** Faster than SSH + docker ps. Gets both Docker state and DNS in parallel. Prevents deploying duplicates.
---
### 2. Write the compose file
```
Tool: Write → hosts/synology/atlantis/stirling-pdf.yaml
```
**Standard Atlantis paths:**
- Config: `/volume2/metadata/docker/<service>/`
- Media: `/volume1/data/media/<type>/`
- Port: pick an unused one (check `list_containers` to see what's taken)
**Key things to include:**
- `restart: unless-stopped`
- `security_opt: no-new-privileges:true`
- LAN DNS servers if the service needs to resolve internal hostnames:
```yaml
dns:
- 192.168.0.200
- 192.168.0.250
```
---
### 3. Create DNS record
```
MCP: cloudflare_create_dns_record(name="pdf", content="184.23.52.14", proxied=True)
```
**Why MCP:** Single call — no need to know the zone ID or handle auth.
**Decision — proxied or not?**
- `proxied=True` (default): for web services — Cloudflare handles DDoS, caching, SSL at edge
- `proxied=False`: for Matrix federation, Headscale, DERP relays, TURN — these need direct IP access
**If proxied=True:** Uses the wildcard CF Origin cert (npm-8) in NPM — no new cert needed.
**If proxied=False:** Needs a real LE cert. Issue via certbot on matrix-ubuntu, add as new `npm-N`.
---
### 4. Check AdGuard — will LAN DNS resolve correctly?
```
MCP: adguard_list_rewrites()
```
Look for the `*.vish.gg → 100.85.21.51` wildcard. This resolves to matrix-ubuntu (`192.168.0.154`) which is where NPM runs — so for most `*.vish.gg` services this is **correct** and no extra rewrite is needed.
**Add a rewrite only if:**
- The service needs to bypass the wildcard (e.g. `pt.vish.gg → 192.168.0.154` was needed because the wildcard mapped to the Tailscale IP, not LAN IP)
- Internal services (Portainer, Atlantis) need to reach this domain and the wildcard points somewhere they can't reach
```
MCP: adguard_add_rewrite(domain="pdf.vish.gg", answer="192.168.0.154") # only if needed
```
---
### 5. Create NPM proxy host
No MCP tool yet for creating proxy hosts — use bash:
```bash
NPM_TOKEN=$(curl -s -X POST "http://192.168.0.154:81/api/tokens" \
-H "Content-Type: application/json" \
-d '{"identity":"your-email@example.com","secret":"..."}' | python3 -c "import sys,json; print(json.load(sys.stdin)['token'])")
curl -s -X POST "http://192.168.0.154:81/api/nginx/proxy-hosts" \
-H "Authorization: Bearer $NPM_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"domain_names": ["pdf.vish.gg"],
"forward_scheme": "http",
"forward_host": "192.168.0.200", # Atlantis LAN IP
"forward_port": 7340,
"certificate_id": 8, # npm-8 = *.vish.gg CF Origin (for proxied domains)
"ssl_forced": true,
"allow_websocket_upgrade": true,
"block_exploits": true,
"locations": []
}'
```
**Cert selection:**
- Proxied `*.vish.gg` → cert `8` (CF Origin wildcard)
- Unproxied `mx.vish.gg` → cert `6` (LE)
- Unproxied `sso.vish.gg` → cert `12` (LE)
- See `docs/admin/mcp-server.md` for full cert table
**After creating**, verify with:
```
MCP: npm_get_proxy_host(host_id=<id>) # check nginx_err is None
MCP: npm_list_proxy_hosts(filter_domain="pdf.vish.gg")
```
---
### 6. Create data directories on the host
```
MCP: ssh_exec(host="atlantis", command="mkdir -p /volume2/metadata/docker/stirling-pdf/configs /volume2/metadata/docker/stirling-pdf/logs")
```
**Why before deploy:** Portainer fails with a bind mount error if the host directory doesn't exist. Always create dirs first.
---
### 7. Commit and push to Git
```bash
git add hosts/synology/atlantis/stirling-pdf.yaml
git commit -m "feat: add Stirling PDF to Atlantis (pdf.vish.gg)"
git push
```
**Why Git first:** Portainer pulls from Git. The file must be in the repo before you create the stack, or Portainer can't find it.
---
### 8. Deploy via Portainer API
```bash
curl -X POST "http://100.83.230.112:10000/api/stacks/create/standalone/repository?endpointId=2" \
-H "X-API-Key: <token>" \
-H "Content-Type: application/json" \
-d '{
"name": "stirling-pdf-stack",
"repositoryURL": "https://git.vish.gg/Vish/homelab.git",
"repositoryReferenceName": "refs/heads/main",
"composeFile": "hosts/synology/atlantis/stirling-pdf.yaml",
"repositoryAuthentication": true,
"repositoryUsername": "Vish",
"repositoryPassword": "<gitea-token>",
"autoUpdate": {"interval": "5m"}
}'
```
**Notes:**
- `endpointId=2` = Atlantis. Use `list_endpoints` to find others.
- `autoUpdate: "5m"` = Portainer polls Git every 5 min and redeploys on changes — this is GitOps.
- The API call often times out (Portainer pulls image + starts container) but the stack is created. Check with `list_stacks` after.
**Alternatively:** Just add the file to Git and wait — if the stack already exists in Portainer with `autoUpdate`, it will pick it up automatically within 5 minutes.
---
### 9. Verify
```
MCP: list_containers(endpoint="atlantis", filter_name="stirling") → running ✓
MCP: check_url(url="https://pdf.vish.gg") → 200 or 401 ✓
MCP: get_container_logs(container_id="stirling-pdf", endpoint="atlantis") → no errors ✓
```
---
### 10. Add Uptime Kuma monitor
```
MCP: kuma_list_groups() → find Atlantis group (ID: 4)
MCP: kuma_add_monitor(
name="Stirling PDF",
monitor_type="http",

parent_id=4,
interval=60
)
MCP: kuma_restart() → required to activate
```
---
## What MCP Replaced
| Step | Without MCP | With MCP |
|------|------------|----------|
| Check if running | `ssh atlantis "sudo /usr/local/bin/docker ps \| grep stirling"` | `list_containers(endpoint="atlantis", filter_name="stirling")` |
| Create DNS | Get CF zone ID → curl with bearer token → parse response | `cloudflare_create_dns_record(name="pdf", content="184.23.52.14")` |
| Check DNS overrides | SSH to Calypso → docker exec AdGuard → cat YAML → grep | `adguard_list_rewrites()` |
| Verify proxy host | Login to NPM UI at 192.168.0.154:81 → navigate to hosts | `npm_get_proxy_host(host_id=50)` |
| Check container logs | `ssh atlantis "sudo /usr/local/bin/docker logs stirling-pdf --tail 20"` | `get_container_logs(container_id="stirling-pdf", endpoint="atlantis")` |
| Add monitor | SSH to pi-5 → docker exec sqlite3 → SQL INSERT → docker restart | `kuma_add_monitor(...)` + `kuma_restart()` |
---
## Common Pitfalls
| Pitfall | Prevention |
|---------|------------|
| Bind mount fails — host dir doesn't exist | `ssh_exec` to create dirs **before** deploying |
| Portainer API times out | Normal — check `list_stacks` after 30s |
| 502 after deploy | Container still starting — check logs, wait 10-15s |
| DNS resolves to wrong IP | Check `adguard_list_rewrites` — wildcard may interfere |
| Wrong cert on proxy host | Check `npm_list_certs` — never reuse an existing `npm-N` |
| Stack not redeploying on push | Check Portainer `autoUpdate` is set on the stack |

# Homelab MCP Server
**Last updated:** 2026-03-21
The homelab MCP (Model Context Protocol) server exposes tools that allow AI assistants (OpenCode/Claude) to interact directly with homelab infrastructure. It runs as a stdio subprocess started by OpenCode on session init.
---
## Location & Config
| Item | Path |
|------|------|
| Server source | `scripts/homelab-mcp/server.py` |
| OpenCode config | `~/.config/opencode/opencode.json` |
| Runtime | Python 3, `fastmcp` library |
| Transport | stdio (started per-session by OpenCode) |
Changes to `server.py` take effect on the **next OpenCode session** (the server is restarted each session).
---
## Tool Categories
### 1. Portainer — Docker orchestration
Manages containers and stacks across all 5 Portainer endpoints.
| Tool | What it does |
|------|-------------|
| `check_portainer` | Health check — version and stack count |
| `list_endpoints` | List all endpoints (Atlantis, Calypso, NUC, Homelab VM, RPi5) |
| `list_stacks` | List all stacks, optionally filtered by endpoint |
| `get_stack` | Get details of a specific stack by name or ID |
| `redeploy_stack` | Trigger GitOps redeploy (pull from Git + redeploy) |
| `list_containers` | List running containers on an endpoint |
| `get_container_logs` | Fetch recent logs from a container |
| `restart_container` | Restart a container |
| `start_container` | Start a stopped container |
| `stop_container` | Stop a running container |
| `list_stack_containers` | List all containers belonging to a stack |
**Endpoints:** `atlantis` (id=2), `calypso` (id=443397), `nuc` (id=443398), `homelab` (id=443399), `rpi5` (id=443395)
---
### 2. Gitea — Source control
Interacts with the self-hosted Gitea instance at `git.vish.gg`.
| Tool | What it does |
|------|-------------|
| `gitea_list_repos` | List all repos in the org |
| `gitea_list_issues` | List open/closed issues for a repo |

---
### 3. AdGuard — Split-horizon DNS
Manages DNS rewrite rules on the Calypso AdGuard instance (`192.168.0.250:9080`).
Critical context: the wildcard `*.vish.gg → 100.85.21.51` (matrix-ubuntu Tailscale IP) requires specific overrides for services that internal hosts need to reach directly (e.g. `pt.vish.gg`, `sso.vish.gg`, `git.vish.gg` all need `→ 192.168.0.154`).
| Tool | What it does |
|------|-------------|
| `adguard_list_rewrites` | List all DNS overrides |
| `adguard_add_rewrite` | Add a new domain → IP override |
| `adguard_delete_rewrite` | Remove a DNS override |
---
### 4. NPM — Nginx Proxy Manager
Manages reverse proxy hosts and SSL certs on matrix-ubuntu (`192.168.0.154:81`).

| `authentik_update_app_launch_url` | Update the dashboard tile URL for an app |
| `authentik_set_provider_cookie_domain` | Set cookie domain on a proxy provider (must be `vish.gg` to avoid redirect loops) |
**Critical:** All Forward Auth proxy providers must have `cookie_domain: vish.gg` or they cause `ERR_TOO_MANY_REDIRECTS`.
---
### 7. Cloudflare — DNS management
Manages DNS records for the `vish.gg` zone.
| Tool | What it does |

# MCP Tool Usage Guide — When and Why
**For Vesper (AI assistant) reference**
This guide explains when to use MCP tools vs other approaches, and how each tool category helps in practice.
---
## The Core Principle
Use the **most targeted tool available**. MCP tools are purpose-built for the homelab — they handle auth, error formatting, and homelab-specific context automatically. Bash + curl is a fallback when no MCP exists.
```
MCP tool available? → Use MCP
No MCP but known API? → Use bash + curl/httpx
Needs complex logic? → Use bash + python3
On a remote host? → Use ssh_exec or homelab_ssh_exec
```
---
## Decision Tree by Task
### "Check if a service is running"
→ `check_url` for HTTP services
→ `list_containers` + `get_container_logs` for Docker containers
→ `ssh_exec` + `systemctl status` for systemd services
### "Deploy a config change"
1. Edit the compose file in the repo (Write tool)
2. `git commit + push` (bash)
3. `redeploy_stack` to trigger GitOps pull
### "Something broke — diagnose it"
→ `get_container_logs` first (fastest)
→ `check_portainer` for overall health
→ `prometheus_query` for metrics
→ `ssh_exec` for deep investigation
### "Add a new service"
1. Write compose file (Write tool)
2. `cloudflare_create_dns_record` for public DNS
3. `adguard_add_rewrite` if it needs a specific LAN override
4. `npm_list_proxy_hosts` + bash NPM API call for reverse proxy
5. `kuma_add_monitor` + `kuma_restart` for uptime monitoring
6. `authentik_list_applications` to check if SSO needed
### "Add a new Tailscale node"
1. `headscale_create_preauth_key` to generate auth key
2. Run `tailscale up --login-server=... --authkey=...` on the new host (ssh_exec)
3. `headscale_list_nodes` to confirm it registered
4. `adguard_add_rewrite` for `hostname.tail.vish.gg → <tailscale_ip>`
5. `kuma_add_monitor` for monitoring
### "Fix a DNS issue"
1. `adguard_list_rewrites` — check current overrides
2. Check if the wildcard `*.vish.gg → 100.85.21.51` is causing interference
3. `adguard_add_rewrite` for specific override before wildcard
4. `cloudflare_list_dns_records` to verify public DNS
### "Fix an Authentik SSO redirect loop"
1. `authentik_list_providers` to find the provider PK
2. `authentik_set_provider_cookie_domain` → set `vish.gg`
3. Check NPM advanced config has `X-Original-URL` header
### "Fix a cert issue"
1. `npm_list_certs` — identify cert IDs and expiry
2. `npm_get_proxy_host` — check which cert a host is using
3. `npm_update_cert` — swap to correct cert
4. **Never reuse an existing npm-N ID** when adding new certs
---
## Tool Category Quick Reference
### When `check_portainer` is useful
- Session start: quick health check before doing anything
- After a redeploy: confirm stacks came up
- Investigating "something seems slow"
### When `list_containers` / `get_container_logs` are useful
- A service is showing errors in the browser
- A stack was redeployed and isn't responding
- Checking if a container is actually running (not just the stack)
### When `adguard_list_rewrites` is essential
Any time a service is unreachable from inside the LAN/Tailscale network:
- `*.vish.gg → 100.85.21.51` wildcard can intercept services
- Portainer, Authentik token exchange, GitOps polling all need correct DNS
- Always check AdGuard before assuming network/firewall issues
### When `npm_*` tools save time
- Diagnosing SSL cert mismatches (cert ID → domain mapping)
- Checking if a proxy host is enabled and what it forwards to
- Swapping certs after LE renewal
### When `headscale_*` tools are needed
- Onboarding a new machine to the tailnet
- Diagnosing connectivity issues (is the node online?)
- Rotating auth keys for automated nodes
### When `authentik_*` tools are needed
- Adding SSO to a new service (check existing providers, create new)
- Fixing redirect loops (cookie_domain)
- Updating dashboard tile URLs after service migrations
### When `cloudflare_*` tools are needed
- New public-facing service needs a domain
- Migrating a service to a different host IP
- Checking if proxied vs unproxied is the issue
### When `kuma_*` tools are needed
- New service deployed → add monitor so we know if it goes down
- Service moved to different URL → update existing monitor
- Organising monitors into host groups for clarity
### When `prometheus_query` helps
- Checking resource usage before/after a change
- Diagnosing "host seems slow" (CPU, memory, disk)
- Confirming a service is being scraped correctly
### When `ssh_exec` is the right choice
- The task requires commands not exposed by any MCP tool
- Editing config files directly on a host
- Running host-specific tools (sqlite3, docker compose, certbot)
- Anything that needs interactive investigation
---
## MCP vs Bash — Specific Examples
| Task | Use MCP | Use Bash |
|------|---------|----------|
| List all Headscale nodes | `headscale_list_nodes` | Only if MCP fails |
| Get container logs | `get_container_logs` | Only for very long tails |
| Add DNS rewrite | `adguard_add_rewrite` | Never — MCP handles auth |
| Check cert on a proxy host | `npm_get_proxy_host` | Only if debugging nginx conf |
| Run SQL on Kuma DB | `kuma_add_monitor` / `kuma_set_parent` | Only for complex queries |
| Redeploy a stack | `redeploy_stack` | Direct Portainer API if MCP times out |
| SSH to a host | `ssh_exec` | `bash + ssh` for interactive sessions |
| Edit a compose file | Write tool + git | Never edit directly on host |
| Check SABnzbd queue | `sabnzbd_queue` | Only if troubleshooting API |
| List all DNS records | `cloudflare_list_dns_records` | Only for bulk operations |
---
## Homelab-Specific Gotchas MCP Tools Handle
### AdGuard wildcard DNS
The `*.vish.gg → 100.85.21.51` wildcard means many `*.vish.gg` domains resolve to matrix-ubuntu's Tailscale IP internally. `adguard_list_rewrites` quickly shows which services have specific overrides and which rely on the wildcard. Before blaming a network issue, always check this.
### NPM cert IDs
Each cert in NPM has a numeric ID (npm-1 through npm-12+). `npm_list_certs` shows the mapping. Overwriting an existing npm-N with a different cert breaks every proxy host using that ID — this happened once and took down all `*.vish.gg` services. `npm_list_certs` prevents this.
### Portainer endpoint IDs
Portainer has 5 endpoints with numeric IDs. The MCP tools accept names (`atlantis`, `calypso`, etc.) and resolve them internally — no need to remember IDs.
### Kuma requires restart
Every DB change to Uptime Kuma requires a container restart — Kuma caches config in memory. `kuma_restart` is always the last step after `kuma_add_monitor` or `kuma_set_parent`.
### Authentik token exchange needs correct DNS
When Portainer (on Atlantis) tries to exchange an OAuth code for a token, it calls `sso.vish.gg`. If AdGuard resolves that to the wrong IP, the exchange times out silently. Always verify DNS before debugging OAuth flows.

- **proxmox-node**: 100.87.12.28:9100 ✅ UP
#### Metrics Collection
- Seattle machine metrics are being successfully scraped
- CPU, memory, disk, and network metrics available
- Historical data collection started immediately after configuration
## Technical Details
### Network Configuration
- **Tailscale Network**: 100.64.0.0/10
- **Seattle IP**: 100.82.197.124
- **Monitoring Port**: 9100 (node_exporter)
- **Protocol**: HTTP (internal network)
### Service Architecture
```
Prometheus (homelab) → Tailscale Network → Seattle Machine:9100 (node_exporter)
```
### Configuration Files Updated
1. `/home/homelab/docker/monitoring/prometheus/prometheus.yml` - Production config
2. `/home/homelab/organized/repos/homelab/prometheus/prometheus.yml` - Repository config
3. Fixed YAML indentation issues for alertmanager targets
## Verification Steps Completed
1. ✅ SSH connectivity to Seattle machine
2. ✅ Node exporter service running and accessible
3. ✅ Firewall rules configured for Tailscale access
4. ✅ Prometheus configuration updated and reloaded
5. ✅ Target health verification (UP status)
6. ✅ Metrics scraping confirmed
7. ✅ Repository configuration synchronized
8. ✅ Git commit with detailed change log
## Monitoring Capabilities
The Seattle machine now provides the following metrics:
- **System**: CPU usage, load average, uptime
- **Memory**: Total, available, used, cached
- **Disk**: Usage, I/O statistics, filesystem metrics
- **Network**: Interface statistics, traffic counters
- **Process**: Running processes, file descriptors
## Alert Coverage
The Seattle machine is now covered by all existing alert rules:
- **InstanceDown**: Triggers if node_exporter becomes unavailable
- **HighCPUUsage**: Alerts when CPU usage > 80% for 2+ minutes
- **HighMemoryUsage**: Alerts when memory usage > 90% for 2+ minutes
- **DiskSpaceLow**: Alerts when root filesystem < 10% free space
## Next Steps
1. **Monitor Performance**: Watch Seattle machine metrics for baseline establishment
2. **Alert Tuning**: Adjust thresholds if needed based on Seattle machine characteristics
3. **Documentation**: This update is documented in the homelab repository
4. **Backup Verification**: Ensure Seattle machine is included in backup monitoring
## Rollback Plan
If issues arise, the configuration can be quickly reverted:
```bash
# Revert Prometheus config
cd /home/homelab/docker/monitoring
git checkout HEAD~1 prometheus/prometheus.yml
docker compose restart prometheus
```

# 🔔 ntfy Notification System Documentation
**Last Updated**: January 2025
**System Status**: Active and Operational
This document provides a complete overview of your homelab's ntfy notification system, including configuration, sources, and modification procedures.
---
## 📋 System Overview
Your homelab uses **ntfy** (pronounced "notify") as the primary notification system. It's a simple HTTP-based pub-sub notification service that sends push notifications to mobile devices and other clients.
### Key Components
| Component | Location | Port | Purpose |
|-----------|----------|------|---------|
| **ntfy Server** | homelab-vm | 8081 | Main notification server |
| **Alertmanager** | homelab-vm | 9093 | Routes monitoring alerts |
| **ntfy-bridge** | homelab-vm | 5001 | Formats alerts for ntfy |
| **signal-bridge** | homelab-vm | 5000 | Forwards critical alerts to Signal |
| **gitea-ntfy-bridge** | homelab-vm | 8095 | Git repository notifications |
### Access URLs
- **ntfy Web Interface**: http://atlantis.vish.local:8081 (internal) or https://ntfy.vish.gg (external)
- **Alertmanager**: http://atlantis.vish.local:9093
- **Grafana**: http://atlantis.vish.local:3300

## 🔧 Current Configuration
### ntfy Server Configuration
**File**: `/home/homelab/docker/ntfy/config/server.yml` (on homelab-vm)
Key settings:
```yaml
base-url: "https://ntfy.vish.gg"
upstream-base-url: "https://ntfy.sh" # Required for iOS push notifications
```
**Docker Compose**: `hosts/vms/homelab-vm/ntfy.yaml`
- **Container**: `NTFY`
- **Image**: `binwiederhier/ntfy`
- **Internal Port**: 80
- **External Port**: 8081
- **Volume**: `/home/homelab/docker/ntfy:/var/cache/ntfy`
### Notification Topic
**Primary Topic**: `homelab-alerts`
All notifications are sent to this single topic, which you can subscribe to in the ntfy mobile app.
---
## 📨 Notification Sources
### 1. Monitoring Alerts (Prometheus → Alertmanager → ntfy-bridge)
**Stack**: `alerting-stack` (Portainer ID: 500)
**Configuration**: `hosts/vms/homelab-vm/alerting.yaml`
**Alert Routing**:
- ⚠️ **Warning alerts** → ntfy only
- 🚨 **Critical alerts** → ntfy + Signal
- ✅ **Resolved alerts** → Both channels (for critical)
**ntfy-bridge Configuration**:
```python
NTFY_URL = "http://NTFY:80"
NTFY_TOPIC = "REDACTED_NTFY_TOPIC"
```
**Alert Types Currently Configured**:
- Host down/unreachable
- High CPU/Memory/Disk usage
- Service failures
- Container resource issues
### 2. Git Repository Events (Gitea → gitea-ntfy-bridge)
**Stack**: `ntfy-stack`
**Configuration**: `hosts/vms/homelab-vm/ntfy.yaml`
**Bridge Configuration**:
```python
NTFY_URL = "https://ntfy.vish.gg"
NTFY_TOPIC = "REDACTED_NTFY_TOPIC"
```
**Supported Events**:
- Push commits
- Pull requests (opened/closed)
- Issues (created/closed)
- Releases
- Branch creation/deletion
### 3. Container Updates (Watchtower)
**Stack**: `watchtower-stack`
**Configuration**: `common/watchtower-full.yaml`
Watchtower sends notifications directly to ntfy when containers are updated.
---
## 🛠️ How to Modify Notifications
### Changing Notification Topics
1. **For Monitoring Alerts**:
```bash
# Edit the alerting stack configuration
vim /home/homelab/organized/scripts/homelab/hosts/vms/homelab-vm/alerting.yaml
# Find line 69 and change:
NTFY_TOPIC = os.environ.get('NTFY_TOPIC', 'your-new-topic')
```
2. **For Git Events**:
```bash
# Edit the ntfy stack configuration
vim /home/homelab/organized/scripts/homelab/hosts/vms/homelab-vm/ntfy.yaml
# Find line 33 and change:
- NTFY_TOPIC="REDACTED_NTFY_TOPIC"
```
3. **Apply Changes via Portainer**:
- Go to http://atlantis.vish.local:10000
- Navigate to the relevant stack
- Click "Update the stack" (GitOps will pull changes automatically)
### Adding New Alert Rules
1. **Edit Prometheus Configuration**:
```bash
# The monitoring stack doesn't currently have alert rules configured
# You would need to add them to the prometheus_config in:
vim /home/homelab/organized/scripts/homelab/hosts/vms/homelab-vm/monitoring.yaml
```
2. **Add Alert Rules Section**:
```yaml
rule_files:
- "/etc/prometheus/alert-rules.yml"
alerting:
alertmanagers:
- static_configs:
- targets:
- alertmanager:9093
```
3. **Create Alert Rules Config**:
```yaml
# Add to configs section in monitoring.yaml
alert_rules:
content: |
groups:
- name: homelab-alerts
rules:
- alert: HighCPUUsage
expr: 100 - (avg by(instance) (rate(node_cpu_seconds_total{mode="idle"}[5m])) * 100) > 80
for: 5m
labels:
severity: warning
annotations:
summary: "High CPU usage on {{ $labels.instance }}"
description: "CPU usage is above 80% for 5 minutes"
```
### Modifying Alert Severity and Routing
**File**: `hosts/vms/homelab-vm/alerting.yaml`
1. **Change Alert Routing**:
```yaml
# Lines 30-37: Modify routing rules
routes:
- match:
severity: critical
receiver: 'critical-alerts'
- match:
severity: warning
receiver: 'ntfy-all'
```
2. **Add New Receivers**:
```yaml
# Lines 39-50: Add new notification channels
receivers:
- name: 'email-alerts'
email_configs:
- to: 'admin@yourdomain.com'
subject: 'Homelab Alert: {{ .GroupLabels.alertname }}'
```
### Customizing Notification Format
**File**: `hosts/vms/homelab-vm/alerting.yaml` (lines 85-109)
The `format_alert()` function controls how notifications appear:
```python
def format_alert(alert):
# Customize title format
title = f"{alertname} [{status_text}] - {instance}"
# Customize message body
body_parts = []
if summary:
body_parts.append(f"📊 {summary}")
if description:
body_parts.append(f"📝 {description}")
# Add custom fields
body_parts.append(f"🕐 {datetime.now().strftime('%H:%M:%S')}")
return title, body, severity, status
```

## 🔍 Troubleshooting
### Common Issues
1. **Notifications not received on iOS**:
- Verify `upstream-base-url: "https://ntfy.sh"` is set in server config
- Restart ntfy container: `docker restart NTFY`
- Re-subscribe in iOS app
2. **Alerts not firing**:
- Check Prometheus targets: http://atlantis.vish.local:9090/targets
- Check Alertmanager: http://atlantis.vish.local:9093
- Verify bridge health: `curl http://atlantis.vish.local:5001/health`
3. **Signal notifications not working**:
- Check signal-api container: `docker logs signal-api`
- Test signal-bridge: `curl http://atlantis.vish.local:5000/health`
### Container Status Check
```bash
# Via Portainer API
curl -s -H "X-API-Key: "REDACTED_API_KEY" \
"http://atlantis.vish.local:10000/api/endpoints/443399/docker/containers/json" | \
jq '.[] | select(.Names[0] | contains("ntfy") or contains("alert")) | {Names: .Names, State: .State, Status: .Status}'
```
### Log Access
- **ntfy logs**: Check via Portainer → Containers → NTFY → Logs
- **Bridge logs**: Check via Portainer → Containers → ntfy-bridge → Logs
- **Alertmanager logs**: Check via Portainer → Containers → alertmanager → Logs

## 🔐 Security Considerations
1. **ntfy Server**: Publicly accessible at https://ntfy.vish.gg
2. **Topic Security**: Uses a single topic `homelab-alerts` - consider authentication if needed
3. **Signal Integration**: Uses encrypted Signal messaging for critical alerts
4. **Internal Network**: Most bridges communicate over internal Docker networks

- **Topic**: `homelab-alerts`
- **Portainer**: http://atlantis.vish.local:10000
## 🔧 Quick Modifications
### Change Notification Topic
1. **For Monitoring Alerts**:
```bash
# Edit: hosts/vms/homelab-vm/alerting.yaml (line 69)
NTFY_TOPIC = os.environ.get('NTFY_TOPIC', 'NEW-TOPIC-NAME')
```
2. **For Git Events**:
```bash
# Edit: hosts/vms/homelab-vm/ntfy.yaml (line 33)
- NTFY_TOPIC="REDACTED_NTFY_TOPIC"
```
3. **Apply via Portainer**: Stack → Update (GitOps auto-pulls)
### Add New Alert Rules
```yaml
# Add to monitoring.yaml prometheus_config:
rule_files:
- "/etc/prometheus/alert-rules.yml"
alerting:
alertmanagers:
- static_configs:
- targets: ["alertmanager:9093"]
```
### Test Notifications
```bash
# Direct test
curl -H "Title: Test" -d "Hello!" https://ntfy.vish.gg/REDACTED_NTFY_TOPIC
# Alert bridge test
curl -X POST http://atlantis.vish.local:5001/alert \
-H "Content-Type: application/json" \

### Current Backup Configuration ✅
| Setting | Value |
|---------|-------|
| **Destination** | Backblaze B2 (`vk-portainer` bucket) |
| **Schedule** | Daily at 3:00 AM |
| **Retention** | 30 days (auto-delete lifecycle rule) |
| **Encryption** | Yes (AES-256) |
| **Backup Size** | ~30 MB per backup |
| **Max Storage** | ~900 MB |
| **Monthly Cost** | ~$0.005 |
### What's Backed Up
| Component | Location | Backup Method | Frequency |
|-----------|----------|---------------|-----------|
| Portainer DB | Atlantis:/portainer | **Backblaze B2** | Daily 3AM |
| Stack definitions | Git repo | Already versioned | On change |
| Container volumes | Per-host | Scheduled rsync | Daily |
| Secrets/Env vars | Portainer | Included in B2 backup | Daily |
---
## Portainer Server Backup
### Active Configuration: Backblaze B2 ✅
Automatic backups are configured via Portainer UI:
- **Settings → Backup configuration → S3 Compatible**
**Current Settings:**
```
S3 Host: https://s3.us-west-004.backblazeb2.com
Bucket: vk-portainer
Region: us-west-004
Schedule: 0 3 * * * (daily at 3 AM)
Encryption: Enabled
```
### Manual Backup via API
```bash
# Trigger immediate backup
curl -X POST "http://vishinator.synology.me:10000/api/backup/s3/execute" \
-H "X-API-Key: "REDACTED_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"accessKeyID": "004d35b7f4bf4300000000001",
"secretAccessKey": "K004SyhG7s+Xv/LDB32SAJFLKhe5dj0",
"region": "us-west-004",
"bucketName": "vk-portainer",
"password": "portainer-backup-2026",
"s3CompatibleHost": "https://s3.us-west-004.backblazeb2.com"
}'
# Download backup locally
curl -X GET "http://vishinator.synology.me:10000/api/backup" \
-H "X-API-Key: "REDACTED_API_KEY" \
-o portainer-backup-$(date +%Y%m%d).tar.gz
```
### Option 2: Volume Backup (Manual)
```bash
# On Atlantis (where Portainer runs)
# Stop Portainer temporarily
docker stop portainer
# Backup the data volume
tar -czvf /volume1/backups/portainer/portainer-$(date +%Y%m%d).tar.gz \
/volume1/docker/portainer/data
# Restart Portainer
docker start portainer
```
### Option 3: Scheduled Backup Script
Create `/volume1/scripts/backup-portainer.sh`:
```bash
#!/bin/bash
BACKUP_DIR="/volume1/backups/portainer"
DATE=$(date +%Y%m%d_%H%M%S)
RETENTION_DAYS=30
# Create backup directory
mkdir -p $BACKUP_DIR
# Backup Portainer data (hot backup - no downtime)
docker run --rm \
-v portainer_data:/data \
-v $BACKUP_DIR:/backup \
alpine tar -czvf /backup/portainer-$DATE.tar.gz /data
# Cleanup old backups
find $BACKUP_DIR -name "portainer-*.tar.gz" -mtime +$RETENTION_DAYS -delete
echo "Backup completed: portainer-$DATE.tar.gz"
```
Add to crontab:
```bash
# Daily at 3 AM
0 3 * * * /volume1/scripts/backup-portainer.sh >> /var/log/portainer-backup.log 2>&1
```
---
## Stack Definitions Backup
All stack definitions are stored in Git (git.vish.gg/Vish/homelab), providing:
- ✅ Version history
- ✅ Change tracking
- ✅ Easy rollback
- ✅ Multi-location redundancy
### Git Repository Structure
```
homelab/
├── Atlantis/ # Atlantis stack configs
├── Calypso/ # Calypso stack configs
├── homelab_vm/ # Homelab VM configs
│ ├── monitoring.yaml
│ ├── openhands.yaml
│ ├── ntfy.yaml
│ └── prometheus_grafana_hub/
│ └── alerting/
├── concord_nuc/ # NUC configs
└── docs/ # Documentation
```
### Backup Git Repo Locally
```bash
# Clone full repo with history
git clone --mirror https://git.vish.gg/Vish/homelab.git homelab-backup.git
# Update existing mirror
cd homelab-backup.git && git remote update
```
---
## Container Volume Backup Strategy
### Critical Volumes to Backup
| Service | Volume Path | Priority | Size |
|---------|-------------|----------|------|
| Grafana | /var/lib/grafana | High | ~500MB |
| Prometheus | /prometheus | Medium | ~2GB |
| ntfy | /var/cache/ntfy | Low | ~100MB |
| Alertmanager | /alertmanager | Medium | ~50MB |
### Backup Script for Homelab VM
Create `/home/homelab/scripts/backup-volumes.sh`:
```bash
#!/bin/bash
BACKUP_DIR="/home/homelab/backups"
DATE=$(date +%Y%m%d)
REMOTE="atlantis:/volume1/backups/homelab-vm"
# Create local backup
mkdir -p $BACKUP_DIR/$DATE
# Backup critical volumes
for vol in grafana prometheus alertmanager; do
docker run --rm \
-v ${vol}_data:/data \
-v $BACKUP_DIR/$DATE:/backup \
alpine tar -czvf /backup/${vol}.tar.gz /data
done
# Sync to remote (Atlantis NAS)
rsync -av --delete $BACKUP_DIR/$DATE/ $REMOTE/$DATE/
# Keep last 7 days locally
find $BACKUP_DIR -maxdepth 1 -type d -mtime +7 -exec rm -rf {} \;
echo "Backup completed: $DATE"
```
---
## Disaster Recovery Procedures
### Scenario 1: Portainer Server Failure
**Recovery Steps:**
1. Deploy new Portainer instance on Atlantis
2. Restore from backup
3. Re-add edge agents (they will auto-reconnect)
```bash
# Deploy fresh Portainer
docker run -d -p 10000:9000 -p 8000:8000 \
--name portainer --restart always \
-v /var/run/docker.sock:/var/run/docker.sock \
-v portainer_data:/data \
portainer/portainer-ee:latest
# Restore from backup
docker stop portainer
tar -xzvf portainer-backup.tar.gz -C /
docker start portainer
```
### Scenario 2: Edge Agent Failure (e.g., Homelab VM)
**Recovery Steps:**
1. Reinstall Docker on the host
2. Install Portainer agent
3. Redeploy stacks from Git
```bash
# Install Portainer Edge Agent
docker run -d \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /var/lib/docker/volumes:/var/lib/docker/volumes \
-v portainer_agent_data:/data \
--name portainer_edge_agent \
--restart always \
-e EDGE=1 \
-e EDGE_ID=<edge-id> \
-e EDGE_KEY=<edge-key> \
-e EDGE_INSECURE_POLL=1 \
portainer/agent:latest
# Stacks will auto-deploy from Git (if AutoUpdate enabled)
# Or manually trigger via Portainer API
```
### Scenario 3: Complete Infrastructure Loss
**Recovery Priority:**
1. Network (router, switch)
2. Atlantis NAS (Portainer server)
3. Git server (Gitea on Calypso)
4. Edge agents
**Full Recovery Checklist:**
- [ ] Restore network connectivity
- [ ] Boot Atlantis, restore Portainer backup
- [ ] Boot Calypso, verify Gitea accessible
- [ ] Start edge agents on each host
- [ ] Verify all stacks deployed from Git
- [ ] Test alerting notifications

# Secrets Management Strategy
**Last updated**: March 2026
**Status**: Active policy
This document describes how credentials and secrets are managed across the homelab infrastructure.
---
## Overview
The homelab uses a **layered secrets strategy** with four components:
| Layer | Tool | Purpose |
|-------|------|---------|
| **Source of truth** | Vaultwarden | Store all credentials; accessible via browser + Bitwarden client apps |
| **CI/CD secrets** | Gitea Actions secrets | Credentials needed by workflows (Portainer token, CF token, etc.) |
| **Runtime injection** | Portainer stack env vars | Secrets passed into containers at deploy time without touching compose files |
| **Public mirror protection** | `sanitize.py` | Strips secrets from the private repo before mirroring to `homelab-optimized` |
---
## Vaultwarden — Source of Truth
All credentials **must** be saved in Vaultwarden before being used anywhere else.
- **URL**: `https://vault.vish.gg` (or via Tailscale: `vault.tail.vish.gg`)
- **Collection structure**:
```
Homelab/
├── API Keys/ (OpenAI, Cloudflare, Spotify, etc.)
├── Gitea API Tokens/ (PATs for automation)
├── Gmail App Passwords/
├── Service Passwords/ (per-service DB passwords, admin passwords)
├── SMTP/ (app passwords, SMTP configs)
├── SNMP/ (SNMPv3 auth and priv passwords)
└── Infrastructure/ (Watchtower token, Portainer token, etc.)
```
**Rule**: If a credential isn't in Vaultwarden, it doesn't exist.
---
## Gitea Actions Secrets
For credentials used by CI/CD workflows, store them as Gitea repository secrets at:
`https://git.vish.gg/Vish/homelab/settings/actions/secrets`
### Currently configured secrets
| Secret | Used by | Purpose |
|--------|---------|---------|
| `GIT_TOKEN` | All workflows | Gitea PAT for repo checkout and Portainer git auth |
| `PORTAINER_TOKEN` | `portainer-deploy.yml` | Portainer API token |
| `PORTAINER_URL` | `portainer-deploy.yml` | Portainer base URL |
| `CF_TOKEN` | `portainer-deploy.yml`, `dns-audit.yml` | Cloudflare API token |
| `NPM_EMAIL` | `dns-audit.yml` | Nginx Proxy Manager login email |
| `NPM_PASSWORD` | `dns-audit.yml` | Nginx Proxy Manager password |
| `NTFY_URL` | `portainer-deploy.yml`, `dns-audit.yml` | ntfy notification topic URL |
| `HOMARR_SECRET_KEY` | `portainer-deploy.yml` | Homarr session encryption key |
| `IMMICH_DB_USERNAME` | `portainer-deploy.yml` | Immich database username |
| `IMMICH_DB_PASSWORD` | `portainer-deploy.yml` | Immich database password |
| `IMMICH_DB_DATABASE_NAME` | `portainer-deploy.yml` | Immich database name |
| `IMMICH_JWT_SECRET` | `portainer-deploy.yml` | Immich JWT signing secret |
| `PUBLIC_REPO_TOKEN` | `mirror-to-public.yaml` | PAT for pushing to `homelab-optimized` |
| `RENOVATE_TOKEN` | `renovate.yml` | PAT for Renovate dependency bot |
### Adding a new Gitea secret
```bash
# Via API
TOKEN="your-gitea-pat"
curl -X PUT "https://git.vish.gg/api/v1/repos/Vish/homelab/actions/secrets/MY_SECRET" \
-H "Authorization: token $TOKEN" \
-H "Content-Type: application/json" \
-d '{"data": "actual-secret-value"}'
```
Or via the Gitea web UI: Repository → Settings → Actions → Secrets → Add Secret.
---
## Portainer Runtime Injection
For secrets needed inside containers at runtime, Portainer injects them as environment variables at deploy time. This keeps credentials out of compose files.
### How it works
1. The compose file uses `${VAR_NAME}` syntax — no hardcoded value
2. `portainer-deploy.yml` defines a `DDNS_STACK_ENV` dict mapping stack names to env var lists
3. On every push to `main`, the workflow calls Portainer's redeploy API with the env vars from Gitea secrets
4. Portainer passes them to the running containers
### Currently injected stacks
| Stack name | Injected vars | Source secret |
|------------|--------------|---------------|
| `dyndns-updater` | `CLOUDFLARE_API_TOKEN` | `CF_TOKEN` |
| `dyndns-updater-stack` | `CLOUDFLARE_API_TOKEN` | `CF_TOKEN` |
| `homarr-stack` | `HOMARR_SECRET_KEY` | `HOMARR_SECRET_KEY` |
| `retro-site` | `GIT_TOKEN` | `GIT_TOKEN` |
| `immich-stack` | `DB_USERNAME`, `DB_PASSWORD`, `DB_DATABASE_NAME`, `JWT_SECRET`, etc. | `IMMICH_DB_*`, `IMMICH_JWT_SECRET` |
### Adding a new injected stack
1. Add the secret to Gitea (see above)
2. Add it to the workflow env block in `portainer-deploy.yml`:
```yaml
MY_SECRET: ${{ secrets.MY_SECRET }}
```
3. Read it in the Python block:
```python
my_secret = os.environ.get('MY_SECRET', '')
```
4. Add the stack to `DDNS_STACK_ENV`:
```python
'my-stack-name': [{'name': 'MY_VAR', 'value': my_secret}],
```
5. In the compose file, reference it as `${MY_VAR}` — no default value
---
## `.env.example` Pattern for New Services
When adding a new service that needs credentials:
1. **Never** put real values in the compose/stack YAML file
2. Create a `.env.example` alongside the compose file showing the variable names with `REDACTED_*` placeholders:
```env
# Copy to .env and fill in real values (stored in Vaultwarden)
MY_SERVICE_DB_PASSWORD="REDACTED_PASSWORD"
MY_SERVICE_SECRET_KEY=REDACTED_SECRET_KEY
MY_SERVICE_SMTP_PASSWORD="REDACTED_PASSWORD"
```
3. The real `.env` file is blocked by `.gitignore` (`*.env` rule)
4. Reference variables in the compose file: `${MY_SERVICE_DB_PASSWORD}`
5. Either:
- Set the vars in Portainer stack environment (for GitOps stacks), or
- Add to `DDNS_STACK_ENV` in `portainer-deploy.yml` (for auto-injection)
---
## Public Mirror Protection (`sanitize.py`)
The private repo (`homelab`) is mirrored to a public repo (`homelab-optimized`) via the `mirror-to-public.yaml` workflow. Before pushing, `.gitea/sanitize.py` runs to:
1. **Delete** files that contain only secrets (private keys, `.env` files, credential docs)
2. **Delete** the `.gitea/` directory itself (workflows, scripts)
3. **Replace** known secret patterns with `REDACTED_*` placeholders across all text files
### Coverage
`sanitize.py` handles:
- All password/token environment variable patterns (`_PASSWORD=`, `_TOKEN=`, `_KEY=`, etc.)
- Gmail app passwords (16-char and spaced `REDACTED_APP_PASSWORD` formats)
- OpenAI API keys (`sk-*` including newer `sk-proj-*` format)
- Gitea PATs (40-char hex, including when embedded in git clone URLs as `https://<token>@host`)
- Portainer tokens (`ptr_` prefix)
- Cloudflare tokens
- Service-specific secrets (Authentik, Mastodon, Matrix, LiveKit, Invidious, etc.)
- Watchtower token (`REDACTED_WATCHTOWER_TOKEN`)
- Public WAN IP addresses
- Personal email addresses
- Signal phone numbers
### Adding a new pattern to sanitize.py
When you add a new service with a credential that `sanitize.py` doesn't catch, add a pattern to `SENSITIVE_PATTERNS` in `.gitea/sanitize.py`:
```python
# Add to SENSITIVE_PATTERNS list:
(
r'(MY_VAR\s*[:=]\s*)["\']?([A-Za-z0-9_-]{20,})["\']?',
r'\1"REDACTED_MY_VAR"',
"My service credential description",
),
```
**Test the pattern before committing:**
```bash
python3 -c "
import re
line = 'MY_VAR=actual-secret-value'
pattern = r'(MY_VAR\s*[:=]\s*)[\"\']?([A-Za-z0-9_-]{20,})[\"\']?'
print(re.sub(pattern, r'\1\"REDACTED_MY_VAR\"', line))
"
```
### Verifying the public mirror is clean
After any push, check that `sanitize.py` ran successfully:
```bash
# Check the mirror-and-sanitize workflow in Gitea Actions
# It should show "success" for every push to main
https://git.vish.gg/Vish/homelab/actions
```
To manually verify a specific credential isn't in the public mirror:
```bash
git clone https://git.vish.gg/Vish/homelab-optimized.git /tmp/mirror-check
grep -r "sk-proj\|REDACTED_APP_PASSWORD\|REDACTED_WATCHTOWER_TOKEN" /tmp/mirror-check/ || echo "Clean"
rm -rf /tmp/mirror-check
```
---
## detect-secrets
The `validate.yml` CI workflow runs `detect-secrets-hook` on every changed file to prevent new unwhitelisted secrets from being committed.
### Baseline management
If you add a new file with a secret that is intentionally there (e.g., `# pragma: allowlist secret`):
```bash
# Update the baseline to include the new known secret
detect-secrets scan --baseline .secrets.baseline
git add .secrets.baseline
git commit -m "chore: update secrets baseline"
```
If `detect-secrets` flags a false positive in CI:
1. Add `# pragma: allowlist secret` to the end of the offending line, OR
2. Run `detect-secrets scan --baseline .secrets.baseline` locally and commit the updated baseline
### Running a full scan
```bash
pip install detect-secrets
detect-secrets scan > .secrets.baseline.new
# Review diff before replacing:
diff .secrets.baseline .secrets.baseline.new
```
---
## Security Scope
### What this strategy protects
- **Public mirror**: `sanitize.py` ensures no credentials reach the public `homelab-optimized` repo
- **CI/CD**: All workflow credentials are Gitea secrets — never in YAML files
- **New commits**: `detect-secrets` in CI blocks new unwhitelisted secrets
- **Runtime**: Portainer env injection keeps high-value secrets out of compose files
### What this strategy does NOT protect
- **Private repo history**: The private `homelab` repo on `git.vish.gg` contains historical plaintext credentials in compose files. This is accepted risk — the repo is access-controlled and self-hosted. See [Credential Rotation Checklist](credential-rotation-checklist.md) for which credentials should be rotated.
- **Portainer database**: Injected env vars are stored in Portainer's internal DB. Protect Portainer access accordingly.
- **Container environment**: Any process inside a container can read its own env vars. This is inherent to the Docker model.
---

# 🔒 Security Hardening Guide
This guide details comprehensive security measures and best practices for securing the homelab infrastructure. Implementing these recommendations will significantly improve the security posture of your network.
## 🛡️ Network Security
### Firewall Configuration
- Open only necessary ports (80, 443) at perimeter
- Block all inbound traffic by default
- Allow outbound access to all services
- Regular firewall rule reviews
### Network Segmentation
- Implement VLANs for IoT and guest networks where possible
- Use WiFi-based isolation for IoT devices (current implementation)
- Segment critical services from general access
- Regular network topology audits
### Tailscale VPN Implementation
- Leverage Tailscale for mesh VPN with zero-trust access
- Configure appropriate ACLs to limit service access
- Monitor active connections and node status
- Rotate pre-authentication keys regularly
## 🔐 Authentication & Access Control
### Multi-Factor Authentication (MFA)
- Enable MFA for all services:
- Authentik SSO (TOTP + FIDO2)
- Portainer administrative accounts
- Nginx Proxy Manager (for internal access only)
- Gitea Git hosting
- Vaultwarden password manager
### Service Authentication Matrix
| Service | Authentication | MFA Support | Notes |
|---------|----------------|-------------|--------|
| Authentik SSO | Local accounts | Yes | Centralized authentication |
| Portainer | Local admin | Yes | Container management |
| Nginx Proxy Manager | Local admin | No | Internal access only |
| Gitea Git | Local accounts | Yes | Code repositories |
| Vaultwarden | Master password | Yes | Password storage |
| Prometheus | Basic auth | No | Internal use only |
### Access Control Lists
- Limit service access to only necessary hosts
- Implement granular Tailscale ACL rules
- Use Portainer role-based access control where available
- Regular review of access permissions
## 🗝️ Secrets Management
### Password Security
- Store all passwords in Vaultwarden (self-hosted Bitwarden)
- Regular password rotations for critical services
- Use unique, strong passwords for each service
- Enable 2FA for Vaultwarden itself
### Environment File Protection
- Ensure all `.env` files have restrictive permissions (`chmod 600`)
- Store sensitive environment variables in Portainer or service-specific locations
- Never commit secrets to Git repositories
- Secure backup of environment files (encrypted where possible)
### Key Management
- Store SSH keys securely with proper permissions
- Rotate SSH keys periodically
- Use hardware security modules where possible for key storage
## 🛡️ Service Security
### Container Hardening
- Run containers as non-root users when possible
- Regularly update container images to latest versions
- Scan for known vulnerabilities using image scanners
- Review and minimize container permissions
### SSL/TLS Security
- Use wildcard certificates via Cloudflare (NPM)
- Enable HSTS for all public services
- Maintain modern cipher suites only
- Regular certificate renewal checks
- Use Let's Encrypt for internal services where needed
### Logging & Monitoring
- Enable logging for all services
- Implement centralized log gathering (planned: Logstash/Loki)
- Monitor for suspicious activities and failed access attempts
- Set up alerts for authentication failures and system anomalies
## 🔍 Audit & Compliance
### Regular Security Audits
- Monthly review of access permissions and user accounts
- Quarterly vulnerability scanning of active services
- Annual comprehensive security assessment
- Review of firewall rules and network access control lists
### Compliance Requirements
- Maintain 3-2-1 backup strategy (3 copies, 2 media types, 1 offsite)
- Regular backup testing for integrity verification
- Incident response documentation updates
- Security policy compliance verification
## 🛠️ Automated Security Processes
### Updates & Patching
- Set up automated vulnerability scanning for containers
- Implement patch management plan for host systems
- Monitor for security advisories affecting services
- Test patches in non-production environments first
### Backup Automation
- Configure HyperBackup tasks with appropriate retention policies
- Enable automatic backup notifications and alerts
- Automate backup integrity checks
- Regular manual verification of critical backup restores
## 🔧 Emergency Security Procedures
### Compromise Response Plan
1. **Isolate**: Disconnect affected systems from network immediately
2. **Assess**: Determine scope and extent of compromise
3. **Contain**: Block attacker access, change all credentials
4. **Eradicate**: Remove malware, patch vulnerabilities
5. **Recover**: Restore from known-good backups
6. **Review**: Document incident, improve defenses
### Emergency Access
- Document physical access procedures for critical systems
- Ensure Tailscale works even during DNS outages
- Maintain out-of-band access methods (IPMI/iLO)
- Keep emergency access documentation securely stored

# Block everything else by default
Deny: All
# Specific port rules
Allow: TCP 443 from Cloudflare IPs only
Allow: TCP 80 from Cloudflare IPs only (redirect to 443)
```
### Cloudflare Configuration
```yaml
# Cloudflare Security Settings
ssl_mode: full_strict # End-to-end encryption
min_tls_version: "1.2"
always_use_https: true
# WAF Rules
waf_enabled: true
bot_management: enabled

```
### Port Exposure
```yaml
# Only these ports exposed to internet (via Cloudflare)
exposed_ports:
- 443/tcp # HTTPS (Nginx Proxy Manager)
# Everything else via Tailscale/VPN only
internal_only:
- 22/tcp # SSH
- 8080/tcp # Portainer
- 9090/tcp # Prometheus
- 3000/tcp # Grafana
- All Docker services
```
---
## 🔒 Secrets Management
### Vaultwarden
Central password manager for all credentials:
```yaml
# Vaultwarden Security Settings
vaultwarden:
admin_token: # Argon2 hashed
signups_allowed: false
invitations_allowed: true
# Password policy
password_hints_allowed: false
password_iterations: 600000 # PBKDF2 iterations
# 2FA enforcement
require_device_email: true
# Session security
login_ratelimit_seconds: 60
login_ratelimit_max_burst: 10
```
### Environment Variables
```bash
# Never store secrets in docker-compose.yml
# Use Docker secrets or environment files
# Bad ❌
environment:
- DB_PASSWORD="REDACTED_PASSWORD"
# Good ✅ - Using .env file
environment:
- DB_PASSWORD="REDACTED_PASSWORD"
# Better ✅ - Using Docker secrets
secrets:
- db_password
```
### Secret Rotation
```yaml
# Secret rotation schedule
rotation_schedule:
api_tokens: 90 days
oauth_secrets: 180 days
database_passwords: 365 days
ssl_certificates: auto (Let's Encrypt)
ssh_keys: on compromise only
```
---
## 🐳 Container Security
### Docker Security Practices
```yaml
# docker-compose.yml security settings
services:
myservice:
# Run as non-root
user: "1000:1000"
# Read-only root filesystem
read_only: true
# Disable privilege escalation
security_opt:
- no-new-privileges:true
# Limit capabilities
cap_drop:
- ALL
cap_add:
- NET_BIND_SERVICE # Only if needed
# Resource limits
deploy:
resources:
limits:
cpus: '1.0'
memory: 512M
```
### Container Scanning
```bash
# Scan images for vulnerabilities
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
aquasec/trivy image myimage:latest
# Scan all running containers
for img in $(docker ps --format '{{.Image}}' | sort -u); do
echo "Scanning: $img"
docker run --rm aquasec/trivy image "$img" --severity HIGH,CRITICAL
done
```
### Image Security
```yaml
# Only use trusted image sources
trusted_registries:
- docker.io/library/ # Official images
- ghcr.io/ # GitHub Container Registry
- lscr.io/linuxserver/ # LinuxServer.io
# Always pin versions
# Bad ❌
image: nginx:latest
# Good ✅
image: nginx:1.25.3-alpine
```
---
## 🛡️ Backup Security
### Encrypted Backups
```bash
# Hyper Backup encryption settings
encryption:
enabled: true
type: client-side # Encrypt before transfer
algorithm: AES-256-CBC
key_storage: local # Never store key on backup destination
# Verify encryption
# Check that backup files are not readable without key
file backup.hbk
# Should show: "data" not "text" or recognizable format
```
### Backup Access Control
```yaml
# Separate credentials for backup systems
backup_credentials:
hyper_backup:
read_only: true # Cannot delete backups
separate_user: backup_user
syncthing:
ignore_delete: true # Prevent sync of deletions
offsite:
encryption_key: stored_offline
access: write_only # Cannot read existing backups
```
---
## 📊 Security Monitoring
### Log Aggregation
```yaml
# Critical logs to monitor
security_logs:
- /var/log/auth.log # Authentication attempts
- /var/log/nginx/access.log # Web access
- Authentik audit logs # SSO events
- Docker container logs # Application events
```
### Alerting Rules
```yaml
# prometheus/rules/security.yml
groups:
- name: security
rules:
- alert: REDACTED_APP_PASSWORD
expr: increase(authentik_login_failures_total[1h]) > 10
labels:

# Service Deprecation Policy
*Guidelines for retiring services in the homelab*
---
## Purpose
This policy outlines the process for deprecating and removing services from the homelab infrastructure.
---
## Reasons for Deprecation
### Technical Reasons
- Security vulnerabilities with no fix
- Unsupported upstream project
- Replaced by better alternative
- Excessive resource consumption
### Operational Reasons
- Service frequently broken
- No longer maintained
- Too complex for needs
### Personal Reasons
- No longer using service
- Moved to cloud alternative
---
## Deprecation Stages
### Stage 1: Notice (2 weeks)
- Mark service as deprecated in documentation
- Notify active users
- Stop new deployments
- Document in CHANGELOG
### Stage 2: Warning (1 month)
- Display warning in service UI
- Send notification to users
- Suggest alternatives
- Monitor usage
### Stage 3: Archive (1 month)
- Export data
- Create backup
- Move configs to archive/
- Document removal in CHANGELOG
### Stage 4: Removal
- Delete containers
- Remove from GitOps
- Update documentation
- Update service inventory
---
## Decision Criteria
### Keep Service If:
- Active users > 1
- Replaces paid service
- Critical infrastructure
- Regular updates available
### Deprecate Service If:
- No active users (30+ days)
- Security issues unfixed
- Unmaintained (>6 months no updates)
- Replaced by better option
### Exceptions
- Critical infrastructure (extend timeline)
- Security vulnerability (accelerate)
- User request (evaluate)
---
## Archive Process
### Before Removal
1. **Export Data**
```bash
# Database
docker exec <db> pg_dump -U user db > backup.sql
# Files
tar -czf service-data.tar.gz /data/path
# Config
cp -r compose/ archive/service-name/
```
2. **Document**
- Date archived
- Reason for removal
- Data location
- Replacement (if any)
3. **Update Dependencies**
- Check for dependent services
- Update those configs
- Test after changes
### Storage Location
```
archive/
├── services/
│ └── <service-name>/
│ ├── docker-compose.yml
│ ├── config/
│ └── README.md (removal notes)
└── backups/
└── <service-name>/
└── (data backups)
```
---
## Quick Removal Checklist
- [ ] Notify users
- [ ] Export data
- [ ] Backup configs
- [ ] Remove from Portainer
- [ ] Delete Git repository
- [ ] Remove from Nginx Proxy Manager
- [ ] Remove from Authentik (if SSO)
- [ ] Update documentation

- [ ] Document in CHANGELOG
---
## Emergency Removal
For critical security issues:
1. **Immediate** - Stop service
2. **Within 24h** - Export data
3. **Within 48h** - Remove from Git
4. **Within 1 week** - Full documentation
---
## Restoring Archived Services
If service needs to be restored:
1. Copy from archive/
2. Review config for outdated settings
3. Test in non-production first
4. Update to latest image
5. Deploy to production
---
## Service Inventory Review
Quarterly review all services:
| Service | Last Used | Users | Issues | Decision |
|---------|-----------|-------|--------|----------|
| Service A | 30 days | 1 | None | Keep |
| Service B | 90 days | 0 | None | Deprecate |
| Service C | 7 days | 2 | Security | Migrate |

---
## Known Issues / Quirks
### Vaultwarden SSO
- Requires `vaultwarden/server:testing` image (SSO not compiled into `:latest`)
- `SSO_AUTHORITY` must include trailing slash to match Authentik's issuer URI
- `SSO_ALLOW_UNKNOWN_EMAIL_VERIFICATION=true` required (Authentik sends `email_verified: False` by default)
- A custom email scope mapping `email_verified true` (pk=`51d15142`) returns `True` for Authentik
- SSO login works but local login kept as primary due to security key/2FA dependency
### Authentik email scope
- Default Authentik email mapping hardcodes `email_verified: False`
- Custom mapping `email_verified true` (pk=`51d15142`) created and applied to Vaultwarden provider
- All other providers use the default mapping (most apps don't check this field)
### Gitea OAuth2 source name case
- Gitea sends `Authentik` (capital A) as the callback path
- Both `authentik` and `Authentik` redirect URIs registered in Authentik provider pk=2
### Portainer
- Migrated from `http://vishinator.synology.me:10000` to `https://pt.vish.gg` on 2026-03-16
- Client secret was stale — resynced from Authentik provider
### Immich (Atlantis) network issues
- Container must be on `immich-stack_default` network (not `immich_default` or `atlantis_default`)
- When recreating container manually, always reconnect to `immich-stack_default` before starting

# 🔐 Synology NAS SSH Access Guide
**🟡 Intermediate Guide**
This guide documents SSH access configuration for Calypso and Atlantis Synology NAS units.
---
## 📋 Quick Reference
| Host | Local IP | Tailscale IP | SSH Port | User |
|------|----------|--------------|----------|------|
| **Calypso** | 192.168.0.250 | 100.103.48.78 | 62000 | Vish |
| **Atlantis** | 192.168.0.200 | 100.83.230.112 | 60000 | vish |
---
## 🔑 SSH Key Setup
### Authorized Key
The following SSH key is authorized on both NAS units:
```
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIBuJ4f8YrXxhvrT+4wSC46myeHLuR98y9kqHAxBIcshx admin@example.com
```
### Adding SSH Keys
On Synology, add keys to the user's authorized_keys:
```bash
mkdir -p ~/.ssh
echo "ssh-ed25519 YOUR_KEY_HERE" >> ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
```
---
## 🖥️ Connection Examples
### Direct Connection (Same LAN)
```bash
# Calypso
ssh -p 62000 Vish@192.168.0.250
# Atlantis
ssh -p 60000 vish@192.168.0.200
```
### Via Tailscale (Remote)
```bash
# Calypso
ssh -p 62000 Vish@100.103.48.78
# Atlantis
ssh -p 60000 vish@100.83.230.112
```
### SSH Config (~/.ssh/config)
```ssh-config
Host calypso
HostName 100.103.48.78
User Vish
Port 62000
Host atlantis
HostName 100.83.230.112
User vish
Port 60000
```
Then simply: `ssh calypso` or `ssh atlantis`
---
## 🔗 Chaining SSH (Calypso → Atlantis)
To SSH from Calypso to Atlantis (useful for network testing):
```bash
# From Calypso
ssh -p 60000 vish@192.168.0.200
```
With SSH agent forwarding (to use your local keys):
```bash
ssh -A -p 62000 Vish@100.103.48.78
# Then from Calypso:
ssh -A -p 60000 vish@192.168.0.200
```
---
## ⚙️ Enabling SSH on Synology
If SSH is not enabled:
1. Open **DSM** → **Control Panel** → **Terminal & SNMP**
2. Check **Enable SSH service**
3. Set custom port (recommended: non-standard port)
4. Click **Apply**
---
## 🛡️ Security Notes
- SSH ports are non-standard (60000, 62000) for security
- Password authentication is enabled but key-based is preferred
- SSH access is available via Tailscale from anywhere
- Consider disabling password auth once keys are set up:
Edit `/etc/ssh/sshd_config`:
```
PasswordAuthentication no
```
---

## 🟢 Verified Online Nodes (March 2026)
As of March 11, 2026, all 16 active nodes verified reachable via ping:
| Node | Tailscale IP | Role |
|------|-------------|------|
| atlantis | 100.83.230.112 | Primary NAS, exit node |
| calypso | 100.103.48.78 | Secondary NAS, Headscale host |
| setillo | 100.125.0.20 | Remote NAS, Tucson |
| homelab | 100.67.40.126 | Main VM (this host) |
| pve | 100.87.12.28 | Proxmox hypervisor |
| vish-concord-nuc | 100.72.55.21 | Intel NUC, exit node |
| pi-5 | 100.77.151.40 | Raspberry Pi 5 |
| matrix-ubuntu | 100.85.21.51 | Atlantis VM |
| guava | 100.75.252.64 | TrueNAS Scale |
| jellyfish | 100.69.121.120 | Pi 5 media/NAS |
| gl-mt3000 | 100.126.243.15 | GL.iNet Beryl AX (travel router, repeater behind GL-MT3600BE, exit node) |
| gl-be3600 | 100.105.59.123 | GL.iNet Slate 7 (travel router, exit node) |
| gl-mt3600be | 100.64.0.10 | GL.iNet Beryl 7 (remote primary gateway, subnet + exit node) |
| homeassistant | 100.112.186.90 | HA Green (via remote subnet, behind GL-MT3600BE) |
| seattle | 100.82.197.124 | Contabo VPS, exit node |
| shinku-ryuu | 100.98.93.15 | Desktop workstation (Windows) |
| moon | 100.64.0.6 | Debian x86_64, remote subnet (`192.168.12.223`, behind GL-MT3600BE) |
| jellyfish | 100.69.121.120 | Remote workstation (behind GL-MT3600BE) |
| headscale-test | 100.64.0.1 | Headscale test node |
### Notes
- **moon** was migrated from public Tailscale (`dvish92@`) to Headscale on 2026-03-14. It is on the `192.168.12.0/24` subnet, now behind the GL-MT3600BE (Beryl 7) router (replaced GL-MT3000 on 2026-04-16). `accept_routes=true` is enabled so it can reach `192.168.0.0/24` (home LAN) via Calypso's subnet advertisement.
- **guava** has `accept_routes=false` to prevent Calypso's `192.168.0.0/24` route from overriding its own LAN replies. See `docs/troubleshooting/guava-smb-incident-2026-03-14.md`.
- **shinku-ryuu** also has `accept_routes=false` for the same reason.

**Last Updated:** April 2026
**Note:** The Feb 2026 alerts (homelab-node and vmi2076105-node offline) were resolved. Both nodes are now online.
