n8n with Docker Swarm

This repository contains a Docker Swarm stack for n8n, a free and open-source workflow automation tool.

Prerequisites

• Docker and Docker Swarm
• Traefik as a reverse proxy
• A domain name for n8n

Installation

1. Fork and clone this repository:

   git clone https://github.com/your-username/n8n.git
   cd n8n

2. Create a .env file from the example:

   cp .env.example .env

3. Edit the .env file and fill in the required values.

4. Deploy the stack:

   docker stack deploy -c docker-compose.yml n8n

Usage

After deploying the stack, you can access the n8n UI at the domain you configured in the docker-compose.yml file (e.g., https://n8n.your-domain.com).

Configuration

The following environment variables need to be set in the .env file:

Variable	Description
POSTGRES_DB	The name of the PostgreSQL database.
POSTGRES_USER	The username for the PostgreSQL database.
POSTGRES_PASSWORD	The password for the PostgreSQL database.
N8N_HOST	The hostname of your n8n instance.
N8N_PROTOCOL	The protocol to use (e.g., https).
N8N_PORT	The port to use (e.g., 5678).
N8N_PROXY_HOPS	The number of proxy hops.
WEBHOOK_URL	The webhook URL for your n8n instance.
GENERIC_TIMEZONE	The timezone to use for your n8n instance.
DB_TYPE	The database type (should be postgresdb).
DB_POSTGRESDB_HOST	The hostname of the PostgreSQL database.
DB_POSTGRESDB_PORT	The port of the PostgreSQL database.
DB_POSTGRESDB_DATABASE	The name of the PostgreSQL database.
DB_POSTGRESDB_USER	The username for the PostgreSQL database.
DB_POSTGRESDB_PASSWORD	The password for the PostgreSQL database.
EXECUTIONS_MODE	The executions mode for n8n (e.g., queue).
QUEUE_BULL_REDIS_HOST	The hostname of the Redis instance.
QUEUE_BULL_REDIS_PORT	The port of the Redis instance.

Traefik Labels

The docker-compose.yml file includes labels for Traefik to automatically configure the reverse proxy. You will need to change the Host rule to match your domain.

      labels:
        - "traefik.enable=true"
        - "traefik.http.routers.n8n.rule=Host(`n8n.your-domain.com`)"
        - "traefik.http.routers.n8n.entrypoints=websecure"
        - "traefik.http.routers.n8n.tls.certresolver=cloudflare"
        - "traefik.http.services.n8n.loadbalancer.server.port=5678"
        - "traefik.docker.network=traefik-public"
