n8n with Cloudflare Tunnel

Simple n8n setup with PostgreSQL and Cloudflare free tunnel for secure public access.

Quick Start

1. Create Tunnel URL

make tunnel

This will:

• Start cloudflared and get a random tunnel URL
• Create .env.local with the WEBHOOK_URL
• Print the public URL

2. Start n8n

docker compose up -d

3. Access n8n

• Local: http://localhost:5678
• Public: https://random-words-1234.trycloudflare.com (from step 1)
• Login: admin / admin

⚠️ Important Warning

If you stop or restart cloudflared, you will lose the tunnel URL!

When this happens:

1. Run make tunnel again to get a new URL
2. Update your webhook URLs in existing workflows
3. Restart n8n: docker compose restart n8n
