This directory contains the configuration for deploying n8n with PostgreSQL using Docker Compose.

• Docker or Podman with docker-compose
• Nginx configured as reverse proxy (see nginx-n8n.conf)
• SSL certificates for n8n.sashi.online

1. Deploy n8n with PostgreSQL:

   ./deploy-podman.sh

2. Check the logs:

   podman logs -f n8n
   podman logs -f n8n-postgres

3. Check status:

   podman pod ps
   podman ps --filter pod=n8n-pod

4. Stop the deployment:

   ./stop-podman.sh

1. Stop any existing n8n containers:

   docker-compose down

2. Start the services:

   docker compose up -d

3. Check the logs:

   docker compose logs -f

4. Check service health:

   docker compose ps

Copy .env.example to .env and modify as needed:

cp .env.example .env

1. Change the encryption key in production!
2. Change the admin password before exposing to the internet
3. Update PostgreSQL password for production use

• URL: https://n8n.sashi.online
• Username: admin
• Password: (see N8N_BASIC_AUTH_PASSWORD in docker-compose.yml)

docker-compose exec postgres pg_dump -U n8n n8n > backups/n8n-backup-$(date +%Y%m%d-%H%M%S).sql

docker-compose exec -T postgres psql -U n8n n8n < backups/your-backup-file.sql

docker-compose ps

# All services
docker-compose logs -f

# Just n8n
docker-compose logs -f n8n

# Just postgres
docker-compose logs -f postgres

docker-compose exec postgres psql -U n8n -d n8n -c "SELECT version();"

curl http://localhost:5678/healthz

1. Database not ready error

   • Ensure PostgreSQL container is healthy
   • Check if database was properly initialized
   • Verify database credentials match

2. Port already in use

   • Stop other services using port 5678
   • Check with: netstat -tlnp | grep 5678

3. Permission issues with volumes

   • Ensure proper ownership: chown -R 100999:100999 volumes/

docker-compose pull
docker-compose up -d

docker image prune -a

• n8n health: http://localhost:5678/healthz
• PostgreSQL: Port 5432 (internal only)

The nginx reverse proxy configuration is in nginx-n8n.conf. Ensure:

1. SSL certificates are valid
2. Proxy passes to http://127.0.0.1:5678
3. WebSocket support is enabled

To reload nginx:

sudo nginx -t
sudo systemctl reload nginx
