## Architecture

```
              Internet
                 |
          Cloudflare (proxied)
                 |
              nb.vish.gg
                 |
      NPM (matrix-ubuntu:443) --- SSL: *.vish.gg LE wildcard cert
                 |
    http://192.168.0.210:8443 (LAN)
                 |
         +-------+-------+
         |       |       |

```

NPM on matrix-ubuntu reaches homelab-vm via its **LAN IP** (192.168.0.210).

## Components

| Container | Image | Purpose |
|-----------|-------|---------|
| `netbox` | linuxserver/netbox:latest | Web UI + API + background worker |
| `netbox-db` | postgres:16-alpine | PostgreSQL database |
| `netbox-redis` | redis:7-alpine | Caching and task queue |

## DNS & Reverse Proxy

- **Cloudflare**: `nb.vish.gg` A record (proxied), auto-updated by DDNS
- **DDNS**: Listed in `ddns-vish-proxied` service (`hosts/synology/atlantis/dynamicdnsupdater.yaml`)
- **NPM** (matrix-ubuntu): Proxy host ID 46 -- `nb.vish.gg` -> `http://192.168.0.210:8443`
  - SSL: Let's Encrypt wildcard certificate (`*.vish.gg`)
  - Force SSL: yes
  - Block exploits: yes

## Deployment

Deployed via `docker compose` with env vars for secrets:

```bash
cd /home/homelab/organized/repos/homelab/hosts/vms/homelab-vm

SUPERUSER_EMAIL=your-email@example.com \
SUPERUSER_PASSWORD="REDACTED_PASSWORD" \
DB_PASSWORD="REDACTED_PASSWORD" \
REDIS_PASSWORD="REDACTED_PASSWORD" \
docker compose -f netbox.yaml -p netbox up -d
```

First startup takes several minutes (DB migrations + static file collection).

## Configuration

Main config persisted at: `/home/homelab/docker/netbox/config/configuration.py`

Key settings:
- `ALLOWED_HOSTS = ['*']` -- NPM handles domain routing
- `TIME_ZONE = 'UTC'`
- `LOGIN_REQUIRED = False` (change to `True` to require auth for read access)
- `SECRET_KEY` -- auto-generated on first run, do not change

To edit:
```bash
sudo nano /home/homelab/docker/netbox/config/configuration.py
docker restart netbox
```

## Authentication (Authentik OIDC)

NetBox uses Authentik SSO via OpenID Connect.

| Setting | Value |
|---------|-------|
| **Provider** | NetBox (PK: 23, OAuth2/OIDC) |
| **Application slug** | `netbox` |
| **Discovery URL** | `https://sso.vish.gg/application/o/netbox/` |
| **Client ID** | `BB7PiOu8xFOl58H2MUfl9IHISVLuJ4UwwMGvmJ9N` |
| **Redirect URI** | `https://nb.vish.gg/oauth/complete/oidc/` |
| **Scopes** | openid, profile, email |
| **User mapping** | `associate_by_email` pipeline -- matches Authentik email to NetBox user |

Login page shows "OpenID Connect" button. The `vish` Authentik user is mapped to a superuser account.

Configuration in `/home/homelab/docker/netbox/config/configuration.py`:
```python
REMOTE_AUTH_ENABLED = True
REMOTE_AUTH_BACKEND = 'social_core.backends.open_id_connect.OpenIdConnectAuth'
REMOTE_AUTH_AUTO_CREATE_USER = True
SOCIAL_AUTH_OIDC_OIDC_ENDPOINT = 'https://sso.vish.gg/application/o/netbox/'
SOCIAL_AUTH_OIDC_KEY = '<client-id>'
SOCIAL_AUTH_OIDC_SECRET = '<client-secret>'
```

## Inventory Data

NetBox is pre-populated with the full homelab inventory:

| Category | Count |
|----------|-------|
| Sites | 3 (Home, Seattle, Contabo VPS) |
| Devices | 19 (NAS, VMs, switches, workstations, RPis) |
| Services | 110 (all Docker containers with ports) |
| IP Addresses | 28 (LAN + Tailscale for all hosts) |
| IP Prefixes | 5 (LAN, Tailscale, Docker, K8s) |
| Interfaces | 39 (10GbE, 1GbE, virtual, Tailscale, switch ports) |
| MAC Addresses | 17 (all physical NICs with SSH access) |
| Cables | 4 (10GbE switch connections) |
| Clusters | 3 (Portainer Docker, Olares K8s, Headscale) |
| Virtual Machines | 3 (homelab-vm, matrix-ubuntu, tdarr-node) |
| Tags | 17 (media, monitoring, devops, ai-ml, etc.) |

## MAC Addresses

NetBox v4.2+ stores MAC addresses as separate objects (`/api/dcim/mac-addresses/`), not as
fields on interfaces. Each MAC is linked to an interface via `assigned_object_type` +
`assigned_object_id`.

Populated MACs (2026-03-30):

| Device | Interface | MAC Address |
|--------|-----------|-------------|
| atlantis | eth0 | 90:09:D0:8B:0C:E9 |
| atlantis | eth1 | 90:09:D0:8B:0C:EA |
| atlantis | ovs_eth2 | 90:09:D0:8B:0C:EB |
| calypso | eth0 | 90:09:D0:5D:DD:DE |
| calypso | ovs_eth2 | 90:09:D0:5B:DC:70 |
| concord-nuc | eno1 | F4:4D:30:65:52:56 |
| guava | enp1s0f0np0 | E8:EB:D3:C1:11:D8 |

| jellyfish | eth0 | 2C:CF:67:24:39:D6 |
| homeassistant | end0 | 20:F8:3B:02:29:A1 |

Devices without MACs (no SSH access): archer-be800, msi-prestige, pi-5-kevin, shield-tv, shinku-ryuu (offline).

## API

REST API at `/api/`, GraphQL at `/graphql/`.

NetBox v4 uses v2 API tokens with the `Bearer` keyword:
```bash
# Create a token via Django shell (plaintext only shown once):
docker exec netbox python3 /app/netbox/netbox/manage.py shell -c "
from users.models import Token, User
admin = User.objects.get(username='admin')
t = Token(user=admin, description='my-token', write_enabled=True)
t.save()
print(f'nbt_{t.key}.{t._token}')
"

# Use the token:
curl -H "Authorization: Bearer nbt_<key>.<plaintext>" https://nb.vish.gg/api/dcim/devices/
```

Note: `API_TOKEN_PEPPERS` must be configured in `configuration.py` for v2 tokens to work.

Key API endpoints:
- `/api/dcim/devices/` -- devices
- `/api/dcim/interfaces/` -- network interfaces
- `/api/dcim/mac-addresses/` -- MAC addresses (v4.2+ separate model)
- `/api/ipam/ip-addresses/` -- IP addresses
- `/api/dcim/cables/` -- physical cabling

## Maintenance

```bash
# Logs
docker logs netbox --tail 50

# Restart
docker restart netbox

# Upgrade
docker compose -f netbox.yaml -p netbox pull && \
docker compose -f netbox.yaml -p netbox up -d

# Backup database
docker exec netbox-db pg_dump -U netbox netbox > /home/homelab/docker/netbox/backup-$(date +%Y%m%d).sql
```
