Deploy and Host n8n (w/ workers) on Railway

n8n is a workflow automation tool that uses a node-based approach to connect services and automate processes. This template deploys n8n with a worker architecture for handling workflow execution at scale.

About Hosting n8n (w/ workers)

n8n (w/ workers) runs as a multi-service architecture where the main instance handles the web interface and API while worker processes execute workflows. The main service manages workflow definitions, user authentication, and the web UI, while workers pull jobs from a Redis queue to execute workflows independently. The Railway template automatically provisions and configures Redis for job queuing and PostgreSQL for workflow storage. Worker scaling allows handling multiple concurrent workflow executions without blocking the main interface.

Common Use Cases

• ETL: Move and transform data between different databases and applications
• Monitoring and Alerting: Set up automated monitoring workflows that trigger alerts based on system conditions

Dependencies for n8n (w/ workers) Hosting

The Railway template includes all required dependencies: Node.js runtime, PostgreSQL database, and Redis message queue.

Deployment Dependencies

• n8n Workflow Demo Video - Key concepts in under 4 minutes
• n8n Documentation - Official documentation
• n8n Integrations - 200+ available nodes

Implementation Details

Architecture Components:

This template deploys four services:

• Primary Service: Main n8n instance serving web UI and API
• Worker Service: Background worker processes for workflow execution
• Redis: Message broker for job queue management
• PostgreSQL: Database for workflow and execution data storage

Worker Configuration:

Workers operate independently from the main service, allowing workflow execution to scale horizontally. The Redis queue coordinates job distribution between the main instance and available workers.

Available Integrations:

n8n provides 200+ nodes for workflow automation. View the complete list at n8n.io/integrations.

Service Configuration:

• Main Instance: Handles web interface, API requests, and workflow management
• Worker Processes: Execute workflows pulled from Redis queue
• Scaling: Add more worker services to handle increased workflow execution load
