Self-Hosting n8n on Docker

Zapier is great for simple tasks, but for enterprise automation, you need control.

The Setup

We'll use Docker Compose to manage both n8n and its PostgreSQL database.

docker-compose.yml

version: '3.8'

services:
  db:
    image: postgres:16
    environment:
      POSTGRES_DB: n8n
      POSTGRES_USER: n8n
      POSTGRES_PASSWORD: ${DB_PASSWORD}

  n8n:
    image: n8nio/n8n:latest
    ports:
      - "5678:5678"
    environment:
      DB_TYPE: postgresdb
      DB_POSTGRESDB_DATABASE: n8n
      DB_POSTGRESDB_HOST: db
      DB_POSTGRESDB_USER: n8n
      DB_POSTGRESDB_PASSWORD: ${DB_PASSWORD}

Deploying this takes less than 5 minutes and gives you unlimited workflow flexibility.
