n8n Setup

How to use this file: Reference this command in a message to Zo (e.g., "run prompt 'Prompts/n8n-setup.prompt.md'") to automatically set up n8n as a hosted service on your Zo Computer. Zo will follow the steps below to install and configure n8n with a public URL.

This prompt sets up n8n (workflow automation) as a hosted service on your Zo Computer.

What it does

1. •Installs n8n globally via npm
2. •Registers n8n as a managed service with a public URL
3. •Configures n8n with appropriate security settings

Prerequisites

• •Node.js and npm (already installed on Zo Computer)

Steps

1. Install n8n

npm install -g n8n

2. Choose a port

Pick an available port (e.g., 48341 or any other high port).

3. Register as a service

Use register_user_service with:

• •label: n8n
• •protocol: http
• •local_port: your chosen port (e.g., 48341)
• •entrypoint: npx n8n
• •workdir: /home/workspace
• •env_vars:
  • •N8N_PORT: your chosen port (e.g., 48341)
  • •N8N_SECURE_COOKIE: false (since we're behind a proxy)
  • •N8N_HOST: n8n-{username}.zocomputer.io (replace with your actual URL)
  • •GENERIC_TIMEZONE: America/New_York (or your preferred timezone)
  • •N8N_PROXY_HOPS: 1 (for proper IP handling behind the proxy)
  • •WEBHOOK_URL: https://n8n-{username}.zocomputer.io/ (replace with your actual URL)
  • •N8N_RUNNERS_ENABLED: true (enables the runners feature)

4. Access your instance

Once registered, you'll get a public URL like:

https://n8n-{username}.zocomputer.io

Configuration

The service will automatically:

• •Store workflows and credentials in /root/.n8n (created automatically by n8n)
• •Run with your Zo Computer user context
• •Restart automatically if it crashes
• •Provide a public HTTPS endpoint

Notes

• •First time you access n8n, you'll need to create an owner account
• •Workflows and credentials persist in your workspace
• •You can update environment variables using update_user_service
• •Check logs at /dev/shm/n8n.log and /dev/shm/n8n_err.log
