Press “Ctrl + X”, press “Y” and then press “Enter” key

Inside the .env file, define the following environment variables, replacing placeholders with your desired values:

  • POSTGRES_DB: Name of your PostgreSQL database (e.g., my_n8n_database).
  • POSTGRES_NON_ROOT_USER: Username for accessing the database (e.g., n8n_user).
  • POSTGRES_NON_ROOT_PASSWORD: Password for the database user.
  • WEBHOOK_URL: Your domain name or Your Server IP(https://your-domain-name.com)
  • N8N_ENCRYPTION_KEY: A strong encryption key for n8n.
## Paste this below command in terminal for generating "N8N_ENCRYPTION_KEY"
cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 24 | head -n 1

Optional: Environment Variable Customization

n8n offers additional environment variables for fine-tuning its behavior. Explore the official documentation for a comprehensive list: external-link-by-oldietech-com

Start the n8n Services:

Execute the following command in your terminal to initiate the deployment using Docker-compose:

docker-compose up -d

The -d flag instructs Docker-compose to run the containers in detached mode, allowing you to continue using your terminal for other tasks.

Verify Installation:

After running the previous command, n8n, PostgreSQL (the database), and the worker container will launch in the background.

Check if the containers are running properly using the following command:

docker-compose ps

This will display the status of all containers associated with the docker-compose.yml file. Ensure the containers are listed as “Up and Running.”

Accessing Your n8n Instance:

By default, n8n is accessible through your web browser at http://localhost:5678. You’ll encounter the n8n setup wizard, guiding you through the initial configuration steps.

Key Considerations:

  • Port Mapping: The default port for n8n is 5678. If this port conflicts with another application, modify the ports section within the docker-compose.yml file to specify a different port.
  • Persistent Data: The data directory for n8n is not persisted by default within Docker containers. To ensure your workflows and data remain intact after container restarts, consider mounting a volume on the host system.
