n8n Workflow: Complete Self-Hosted Deployment Guide

How This Blueprint Works

Deploy n8n on your own infrastructure for complete control over data, costs, and scaling. This blueprint provides the Docker Compose configuration, PostgreSQL setup, Nginx reverse proxy with SSL, and production-hardening steps needed for a self-hosted n8n instance.

The Execution Sequence

1. Docker Setup — Create a docker-compose.yml with three services: n8n (docker.n8n.io/n8nio/n8n:latest), PostgreSQL 15, and Traefik for reverse proxy. Mount volumes for n8n_data, postgres_data, and traefik_data for persistence.
2. Database Configuration — n8n uses SQLite by default. For production, configure PostgreSQL with environment variables: DB_TYPE=postgresdb, DB_POSTGRESDB_DATABASE=n8n, DB_POSTGRESDB_USER=n8n, DB_POSTGRESDB_PASSWORD=strong_password, DB_POSTGRESDB_HOST=postgres.
3. Nginx + SSL — Traefik auto-proxies and provisions Let’s Encrypt TLS certificates. Configure labels on the n8n container: traefik.enable=true, traefik.http.routers.n8n.rule=Host(n8n.yourdomain.com). Certificates renew automatically.
4. Backup Strategy — Add a cron job on the host that runs pg_dump and tar-s the SQLite .n8n directory. Upload backups to S3-compatible storage using rclone. Retain 7 daily, 4 weekly, and 12 monthly snapshots.
5. Security Hardening — Set N8N_ENCRYPTION_KEY (32-byte hex), enable N8N_METRICS=false, configure N8N_ALLOW_UNAUTHORIZED_EMITTER_CONNECTIONS=false, and set N8N_BLOCK_FILE_ACCESS_TO_N8N_FOLDER_FILES=true in production.

FAQ

What are the minimum server requirements for self-hosted n8n?

1 vCPU, 2 GB RAM, 20 GB SSD for light usage. For production with 10+ concurrent executions: 2 vCPU, 4 GB RAM, 50 GB SSD. Use AWS EC2 t3.medium or equivalent.

Can I scale n8n horizontally?

Yes. n8n supports worker nodes for parallel execution. Configure N8N_EXECUTORS_PROCESS=1 and add additional n8n-worker containers. Share a single PostgreSQL and Redis instance.

How do I update my self-hosted n8n instance?

Pull the latest image (docker compose pull), restart (docker compose up -d), and run database migrations automatically. Check the changelog for breaking changes before upgrading major versions.
