n8n

n8n is a workflow automation platform that allows you to connect various services together.

Architecture

The n8n deployment includes two containers:

• n8n — The main application server
• n8n-postgres — PostgreSQL database for persistent storage

These containers communicate over a dedicated n8n_net Docker network.

Setup

n8n is enabled through the Container Map. No additional configuration is required — the playbook automatically:

1. Creates the required directory structure
2. Generates a 64-character encryption key for n8n
3. Downloads the PostgreSQL initialization script
4. Configures PostgreSQL with default credentials

Accessing

Once running, n8n is accessible via Traefik at n8n.<domain>. The first time you access it, you’ll need to create an owner account.

Default Database Credentials

The PostgreSQL database uses default credentials that are configured in the .env file:

• Root user: n8nroot
• Root password: n8nr00tpassw0rd
• Application user: n8nnonroot
• Application password: n8nnonr00tpassw0rd
• Database name: n8n

Warning

If you need to change the database credentials, use a Container Override to set the environment variables N8N_POSTGRES_USER, N8N_POSTGRES_PASS, N8N_POSTGRES_NON_ROOT_USER, N8N_POSTGRES_NON_ROOT_PASSWORD, and N8N_POSTGRES_DB.
