Deploy and Host n8n Enterprise-Ready Stack on Railway

n8n Enterprise-Ready Stack is a production-grade, self-hosted workflow automation platform combining n8n with PostgreSQL HA and Redis for queue management. Deploy with a single click and get infinite horizontal scaling, automatic failover, and enterprise reliability.

About Hosting n8n Enterprise-Ready Stack

Deploying n8n in production requires a robust database, a queue system for high-volume executions, and the ability to scale workers. This template provides:

• PostgreSQL HA with Primary-Replica replication
• Redis for queue-based execution and scaling
• n8n Main Instance serving web UI and webhooks
• n8n Workers processing executions in parallel
• External Task Runner for secure, isolated code execution (Python/JS)

Everything deploys automatically with proper networking, health checks, and restart policies.

Configuration

🎯 Easy Configuration - Single Source of Truth

Edit environment variables in the n8n service only!

This template uses a Single Source of Truth pattern:

• ✅ Edit environment variables in the n8n service only
• ✅ n8n-worker automatically syncs values from n8n via ${{n8n.VARIABLE}}
• ✅ n8n-task-runner automatically syncs required values from n8n
• ✅ No need to edit ENV in worker or task runner - everything syncs automatically

Example: To change timezone to Asia/Bangkok

1. Go to n8n service → Variables
2. Edit GENERIC_TIMEZONE="Asia/Bangkok" and TZ="Asia/Bangkok"
3. Done! Worker and Task Runner will use the same values automatically

Auto-Generated Variables

Customizable Settings (Edit in n8n service only)

Scaling Guide

Horizontal Scaling

Duplicate n8n-worker service to add more workers.

Getting Started

🚀 Simple 3-Step Installation

1. Deploy

   • Click the "Deploy on Railway" button above
   • Railway will automatically create 7 services:
     • PostgreSQL Primary + Replica + Proxy
     • Redis
     • n8n (Main)
     • n8n-worker
     • n8n-task-runner

2. Wait for Deployment

   • Takes 3-5 minutes
   • Verify all services show "Active" (green status)

3. Access n8n

   • Click on n8n service → Settings → Networking
   • Enable Public Domain URL
   • Create your first admin account

⚙️ Customization (Optional)

Want to change timezone or other settings?

• Go to n8n service → Variables
• Edit the variables you need (e.g., GENERIC_TIMEZONE, TZ)
• Done! No need to edit worker or task runner

Troubleshooting

❌ n8n won't start

• ✅ Verify PostgreSQL Primary is "Active"
• ✅ Wait 2-3 minutes for database initialization
• ✅ Check that N8N_ENCRYPTION_KEY was auto-generated

❌ Workers not processing

• ✅ Verify Redis is "Active"
• ✅ Check that EXECUTIONS_MODE=queue in n8n service
• ✅ Review worker logs for error messages

❌ Database connection errors

• ✅ Wait 2-3 minutes for PostgreSQL Proxy to be ready
• ✅ Verify passwords match across services
• ✅ Restart n8n service after PostgreSQL is ready

💡 Tips

• View logs at each service → Deployments → View Logs
• If issues persist, restart the problematic service
• Edit ENV in n8n service only - workers sync automatically

Why Deploy n8n Enterprise-Ready Stack on Railway?
