After a lot of great feedback, I’ve pushed a major update to my n8n_nginx installer—a fully automated setup script for deploying a complete n8n stack. It now runs on Linux, macOS, and Windows, and handles every part of the installation for you:
-
Installs Docker, Docker Compose, n8n, nginx, PostgreSQL (with pgvector), and optionally the Portainer Agent
-
Sets up Let’s Encrypt SSL using a certbot container with DNS-01 challenges (supports Cloudflare, Route53, Google DNS, DigitalOcean)
-
Requires zero manual config editing—just answer the setup prompts
-
Verifies DNS records, IP alignment, and your Docker environment (including auto-installing Docker if missing)
-
Detects LXC environments and provides tailored guidance for Docker inside LXC on Proxmox
-
Automatically retrieves and renews TLS certificates
-
Health-checks all services after installation and generates a clear summary report
A few people asked why I don’t simply terminate SSL at Cloudflare. In our environment, we run internal networks and want to avoid hairpinning traffic back through Cloudflare from inside the office. Using a proper SSL cert on the host avoids CORS issues and keeps everything local. This setup also works perfectly with Cloudflare Tunnels, which we use to securely expose our n8n webhooks.
