## Workflow Auto-Reload System

### Configuration
The system includes an automatic workflow reload mechanism that ensures workflows persist across container restarts:

- **Service:** `n8n-workflow-reload.service` (systemd)
- **Status:** ✅ Enabled and configured
- **Trigger:** Runs on LXC container start
- **Template:** `/opt/customer-stack/workflow-template.json`
- **Script:** `/opt/customer-stack/reload-workflow.sh`

### How It Works
1. On container restart, systemd triggers the reload service
2. Service waits for n8n to be ready
3. Automatically recreates credentials (PostgreSQL, Ollama)
4. Re-imports workflow from template
5. Activates the workflow
6. No manual intervention required

---

## Next Steps

### 1. Verify Ollama Connectivity ⚠️
```bash
# Test from Proxmox host
curl http://192.168.45.3:11434/api/tags

# Test from container
pct exec 769276659 -- bash -lc "curl http://192.168.45.3:11434/api/tags"
```

### 2. Configure NGINX Reverse Proxy
The installation script attempted to configure the NGINX reverse proxy on OPNsense. Verify:

```bash
# Check if proxy was configured
curl -I https://sb-1769276659.userman.de
```

If not configured, run manually:
```bash
./setup_nginx_proxy.sh --ctid 769276659 --hostname sb-1769276659 \
  --fqdn sb-1769276659.userman.de --backend-ip 192.168.45.45 --backend-port 5678
```

### 3. Test RAG Workflow

#### Upload a Document
1. Access the upload form: `https://sb-1769276659.userman.de/form/rag-upload-form`
2. Upload a PDF document
3. Verify it's processed and stored in the vector database

#### Test Chat Interface
1. Access the chat webhook: `https://sb-1769276659.userman.de/webhook/rag-chat-webhook/chat`
2. Send a test message
3. Verify the AI responds using the uploaded documents

#### Verify Vector Storage
```bash
# Check documents in database
pct exec 769276659 -- bash -lc "docker exec customer-postgres psql -U customer -d customer -c 'SELECT COUNT(*) FROM documents;'"

# Check via PostgREST API
curl http://192.168.45.45:3000/documents
```

### 4. Monitor System Health

#### View Logs
```bash
# Installation log
tail -f logs/sb-1769276659.log

# Container logs (all services)
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose logs -f"

# Individual service logs
pct exec 769276659 -- bash -lc "docker logs -f customer-postgres"
pct exec 769276659 -- bash -lc "docker logs -f customer-postgrest"
pct exec 769276659 -- bash -lc "docker logs -f n8n"
```

#### Check Container Status
```bash
# Container status
pct status 769276659

# Docker containers
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose ps"

# Resource usage
pct exec 769276659 -- bash -lc "free -h && df -h"
```

### 5. Backup Strategy

#### Important Directories to Backup
```
/opt/customer-stack/volumes/postgres/data  # Database data
/opt/customer-stack/volumes/n8n-data       # n8n workflows and settings
/opt/customer-stack/.env                   # Environment configuration
/opt/customer-stack/workflow-template.json # Workflow template
```

#### Backup Commands
```bash
# Backup PostgreSQL
pct exec 769276659 -- bash -lc "docker exec customer-postgres pg_dump -U customer customer > /tmp/backup.sql"

# Backup n8n data
pct exec 769276659 -- bash -lc "tar -czf /tmp/n8n-backup.tar.gz /opt/customer-stack/volumes/n8n-data"
```

---

## Troubleshooting

### Container Won't Start
```bash
# Check container status
pct status 769276659

# Start container
pct start 769276659

# View container logs
pct exec 769276659 -- journalctl -xe
```

### Docker Services Not Running
```bash
# Check Docker status
pct exec 769276659 -- systemctl status docker

# Restart Docker
pct exec 769276659 -- systemctl restart docker

# Restart stack
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose restart"
```

### n8n Not Accessible
```bash
# Check n8n container
pct exec 769276659 -- docker logs n8n

# Restart n8n
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose restart n8n"

# Check port binding
pct exec 769276659 -- netstat -tlnp | grep 5678
```

### Database Connection Issues
```bash
# Test PostgreSQL
pct exec 769276659 -- docker exec customer-postgres pg_isready -U customer

# Check PostgreSQL logs
pct exec 769276659 -- docker logs customer-postgres

# Restart PostgreSQL
pct exec 769276659 -- bash -lc "cd /opt/customer-stack && docker compose restart postgres"
```

## Performance Optimization

### Recommended Settings
- **Memory:** 4GB is sufficient for moderate workloads
- **CPU:** 4 cores recommended for concurrent operations
- **Storage:** Monitor disk usage, especially for vector embeddings

### Monitoring Commands
```bash
# Container resource usage
pct exec 769276659 -- bash -lc "docker stats --no-stream"

# Database size
pct exec 769276659 -- bash -lc "docker exec customer-postgres psql -U customer -d customer -c 'SELECT pg_size_pretty(pg_database_size(current_database()));'"

# Document count
pct exec 769276659 -- bash -lc "docker exec customer-postgres psql -U customer -d customer -c 'SELECT COUNT(*) FROM documents;'"
```
