n8n Automation

A self-hosted n8n automation stack with PostgreSQL 16 as the persistence layer for workflows, credentials, and execution history. n8n is configured with basic authentication and exposes its web editor on port 5678, while PostgreSQL stores all data in a named volume for durability. The stack supports webhook URLs, timezone configuration, and execution pruning out of the box. Both services run on an internal backend network with health checks and resource limits to ensure stable long-running operation. Simply set the environment variables and access the n8n editor to start building automation workflows.

When to Use

This template is ideal for setting up a n8n automation environment. All services are pre-configured with healthchecks, resource limits, and sensible defaults. Customize environment variables before deploying to production.

Tips

Change all default passwords before deploying
Review resource limits for your hardware
Add a reverse proxy for production HTTPS
Configure backup strategies for data volumes
