Self-Hosting n8n with Docker Compose: A Step-by-Step Guide for Seamless Workflow Automation

In today’s fast-paced digital world, automating repetitive tasks can save time, reduce errors, and boost productivity. n8n is a powerful, open-source workflow automation tool that lets you connect apps, APIs, and services without writing code. While n8n offers a cloud version, self-hosting it gives you full control over your data and workflows.

In this guide, we’ll walk through how to self-host n8n using Docker Compose for a seamless, scalable, and secure automation setup.

Why Self-Host n8n with Docker Compose?

Self-hosting n8n comes with several advantages:

• Data Privacy: Keep sensitive workflows and data on your own infrastructure.
• Customization: Tailor the setup to your needs, including plugins and integrations.
• Cost-Effective: Avoid subscription fees for the cloud version.
• Scalability: Easily scale resources as your automation needs grow.

Docker Compose simplifies deployment by managing containers and dependencies in a single configuration file, making it ideal for self-hosting n8n.

Prerequisites

Before diving in, ensure you have:

1. Docker and Docker Compose installed on your server or local machine.
2. Basic familiarity with the command line and YAML files.
3. A domain name and SSL certificate (optional but recommended for production).

Step 1: Create a Docker Compose File

Start by creating a docker-compose.yml file to define the n8n service:

```yaml
version: '3'

services:
n8n:
image: n8nio/n8n
restart: unless-stopped
ports:
- "5678:5678"
environment:
- N8N_BASIC_AUTH_ACTIVE=true
- N8N_BASIC_AUTH_USER=
- N8N_BASIC_AUTH_PASSWORD=
volumes:
- n8n_data:/home/node/.n8n
volumes:
n8n_data:
```

Key Configuration Notes:
- ports: Maps port 5678 (n8n’s default) to your host.
- environment: Enables basic authentication for security. Replace <your-username> and <your-password> with your credentials.
- volumes: Persists workflow data between container restarts.

Step 2: Launch n8n

Run the following command in the same directory as your docker-compose.yml file:

bash docker-compose up -d

This starts n8n in detached mode. To verify it’s running, check:

bash docker ps

You should see the n8n container listed.

Step 3: Access the n8n Web Interface

Open your browser and navigate to:

http://<your-server-ip>:5678

Log in using the credentials you set in the docker-compose.yml file.

Step 4: Secure Your Instance (Optional but Recommended)

For production use, consider:

1. SSL/TLS: Use a reverse proxy like Nginx or Traefik with Let’s Encrypt.
2. Firewall Rules: Restrict access to port 5678.
3. Backups: Regularly back up the n8n_data volume.

Step 5: Explore and Automate

With n8n running, you can:
- Create workflows using the visual editor.
- Connect to 300+ integrations (e.g., Slack, Google Sheets, GitHub).
- Schedule or trigger workflows via webhooks.

Troubleshooting Common Issues

• Port Conflicts: Ensure no other service is using port 5678.
• Authentication Errors: Double-check the credentials in docker-compose.yml.
• Data Persistence: Verify the volume is correctly mounted.

Conclusion

Self-hosting n8n with Docker Compose is a straightforward way to take control of your workflow automation. With this setup, you gain flexibility, security, and scalability—all while keeping your data private.
