Set up n8n workflow automation

n8n Setup

How to use this file: Reference this command in a message to Zo (e.g., "run n8n-setup") 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
Copy

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
Copy

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
