./deploy.sh deploy           # Full deployment
./deploy.sh setup-ollama     # Setup AI model only

# Management
./deploy.sh status           # Check all services

## 🌐 Network Configuration

### Router Port Forwarding
Configure your router to forward:
- **Port 80** → **192.168.0.250:8880** (HTTP)
- **Port 443** → **192.168.0.250:8443** (HTTPS)

### NPM Proxy Host Configuration
In NPM Admin UI (http://192.168.0.250:81):

1. **rx.vish.gg**:
   - Forward Hostname/IP: `192.168.0.250`
   - Forward Port: `9751`
   - Enable SSL with Cloudflare Origin Certificate

2. **rxdl.vish.gg** (Download Service):
   - Forward Hostname/IP: `192.168.0.250`
   - Forward Port: `9753`
   - Enable SSL with Cloudflare Origin Certificate

## 🔍 Troubleshooting

### AI Features Not Working
```bash
# Check Ollama service
./deploy.sh logs | grep ollama

# Verify model is loaded
ssh Vish@192.168.0.250 -p 62000 "sudo /usr/local/bin/docker exec Resume-OLLAMA-V5 ollama list"

# Test AI API directly
curl http://192.168.0.250:11434/api/generate -d '{
  "model": "llama3.2:3b",
  "prompt": "Write a professional summary for a software engineer",
  "stream": false
}'
```

### External Access Issues
```bash
# Test DNS resolution
nslookup rx.vish.gg

# Test external connectivity
curl -I https://rx.vish.gg

# Check NPM proxy configuration
./deploy.sh status
```

### Service Health Check
```bash
# Check all containers
ssh Vish@192.168.0.250 -p 62000 "sudo /usr/local/bin/docker ps"

# Check specific service logs
ssh Vish@192.168.0.250 -p 62000 "sudo /usr/local/bin/docker logs Resume-ACCESS-V5"
```

## 📊 Performance Metrics

### Resource Usage (Typical)
- **CPU**: 2-4 cores during AI inference
- **RAM**: 6-8GB total (4GB for Ollama + 2-4GB for other services)
- **Storage**: ~15GB (2GB model + 3GB images + data)
- **Network**: Minimal (all AI processing local)

### Response Times
- **App Load**: <2s
- **AI Suggestions**: 3-10s (depending on prompt complexity)
- **PDF Generation**: 2-5s
- **File Upload**: <1s (local S3)

## 🔐 Security Considerations

### Access Control
- All services behind NPM reverse proxy
- External access only via HTTPS
- AI processing completely local (no data leaves network)
- Database credentials environment-specific

### SSL/TLS
- Cloudflare Origin Certificates in NPM
- End-to-end encryption for external access
- Internal services use HTTP (behind firewall)

## 🔄 Backup & Recovery

### Critical Data Locations
```bash
# Database backup
/volume1/docker/rxv5/db/

# File storage backup  
/volume1/docker/rxv5/seaweedfs/

# AI model data
/volume1/docker/rxv5/ollama/

# NPM configuration
/volume1/docker/nginx-proxy-manager/data/
```

### Backup Commands
```bash
# Create backup
ssh Vish@192.168.0.250 -p 62000 "sudo tar -czf /volume1/backups/rxv5-$(date +%Y%m%d).tar.gz /volume1/docker/rxv5/"

# Restore from backup
ssh Vish@192.168.0.250 -p 62000 "sudo tar -xzf /volume1/backups/rxv5-YYYYMMDD.tar.gz -C /"
```

## 📈 Monitoring

### Health Endpoints
- **Application**: http://192.168.0.250:9751/health
- **Database**: PostgreSQL health checks via Docker
- **AI Service**: http://192.168.0.250:11434/api/tags
- **Storage**: SeaweedFS S3 API health

### Log Locations
```bash
# Application logs
sudo /usr/local/bin/docker logs Resume-ACCESS-V5

# AI service logs  
sudo /usr/local/bin/docker logs Resume-OLLAMA-V5

# Database logs
sudo /usr/local/bin/docker logs Resume-DB-V5
```

## 🎉 Success Criteria

✅ **External Access**: https://rx.vish.gg responds with 200  
✅ **AI Integration**: Ollama model loaded and responding  
✅ **PDF Generation**: Browserless service healthy  
✅ **File Storage**: SeaweedFS S3 API functional  
✅ **Database**: PostgreSQL healthy and accessible
