railway_skill

Overview

This skill deploys and manages applications on the Railway platform. It guides CLI-based workflows, project configuration, and service management for containerized apps, databases, volumes, cron jobs, and private networking. Use it to automate deployments, link services, and keep production services healthy and persistent.

How this skill works

The skill uses Railway CLI commands and railway.toml configuration to build and deploy services. It configures builders (nixpacks or Dockerfile), manages environment variables and database services, attaches volumes for persistent storage, and sets up private DNS for internal service communication. It also supports health checks, cron schedules, and multi-service project workflows.

When to use it

• Deploy a new containerized or Node app to Railway quickly using railway up
• Provision and connect managed databases (Postgres, Redis, MySQL) for your app
• Set up private networking so services communicate securely via internal DNS
• Attach persistent volumes to retain state or uploaded files across deploys
• Run periodic tasks with cron schedules or deploy background workers separately

Best practices

• Use railway.toml to declare build, start, and healthcheck settings for reproducible deploys
• Keep secrets out of source by storing them with railway variables and loading from .env when needed
• Prefer healthcheck endpoints so Railway can monitor and restart unhealthy services
• Use Nixpacks for zero-configuration builds or Dockerfile when you need full control
• Organize multi-service projects into separate service folders and deploy them independently

Example use cases

• Deploy a Node/Express API with a Postgres database and attach DATABASE_URL from Railway variables
• Run a worker service for background jobs and a separate frontend service; deploy each folder with railway up
• Bind a persistent volume to store user uploads at /app/data so files survive redeploys
• Deploy with a Dockerfile when you require custom OS packages or a specific runtime
• Configure an internal DNS host like postgres.railway.internal for secure DB connections between services
