Railway Deploy Skill

Description

Automated Railway deployment and configuration management. Handles environment variables, service deployment, health checks, and rollback procedures.

Capabilities

  • Set/update environment variables
  • Trigger redeployments
  • Check deployment status
  • View deployment logs
  • Verify service health
  • Rollback to previous deployments
  • Manage multiple services (backend, auth server, database)

Inputs

  • --service (required): Service to deploy (backend|auth-server|all)
  • --action (required): Action to perform (deploy|config|status|rollback)
  • --env-vars (optional): Environment variables to set (KEY=VALUE format, comma-separated)
  • --wait (optional): Wait for deployment to complete (default: true)
  • --health-check (optional): Run health checks after deployment (default: true)

Process

Action: config (Set Environment Variables)

1. Parse environment variables from --env-vars
2. For each KEY=VALUE pair:
   a. Validate variable name (no spaces, valid characters)
   b. Set in Railway using CLI or API
   c. Confirm variable is set
3. Optionally trigger redeploy (--redeploy flag)

Action: deploy (Deploy Service)

1. Check current deployment status
2. Trigger new deployment:
   a. Push latest code to GitHub (if needed)
   b. Railway auto-deploys or use `railway up`
3. Monitor deployment progress:
   a. Check build logs
   b. Wait for "Deployed" status
   c. Capture any build errors
4. Run health checks:
   a. GET {service_url}/health
   b. Verify 200 OK response
   c. Check response time
5. Verify service functionality:
   a. Backend: Test /api/health endpoint
   b. Auth Server: Test /health endpoint
   c. Check database connectivity

Action: status (Check Deployment Status)

1. Get latest deployment info:
   a. Deployment ID
   b. Status (Building, Deployed, Failed)
   c. Commit hash
   d. Deployed timestamp
2. Get service metrics:
   a. CPU usage
   b. Memory usage
   c. Request count
3. Check service health:
   a. Uptime
   b. Recent errors
   c. Response times

Action: rollback (Rollback Deployment)

1. List recent deployments (last 10)
2. Select previous stable deployment
3. Redeploy that version
4. Wait for rollback to complete
5. Run health checks
6. Verify service is working

Example Usage

Set Environment Variable

bash
claude-code /railway-deploy --service backend --action config --env-vars "AUTH_SERVER_URL=https://auth-server-production-8251.up.railway.app"

Deploy Backend

bash
claude-code /railway-deploy --service backend --action deploy --wait true --health-check true

Deploy All Services

bash
claude-code /railway-deploy --service all --action deploy

Check Status

bash
claude-code /railway-deploy --service backend --action status

Rollback

bash
claude-code /railway-deploy --service backend --action rollback

Set Multiple Variables and Deploy

bash
claude-code /railway-deploy --service backend --action config --env-vars "AUTH_SERVER_URL=https://auth.railway.app,CORS_ORIGINS=https://frontend.vercel.app" --redeploy

Environment Variables Management

Critical Backend Variables

bash
# Auth Server URL (REQUIRED)
AUTH_SERVER_URL=https://auth-server-production-8251.up.railway.app

# Database (auto-set by Railway)
DATABASE_URL=postgresql://...

# CORS Origins
CORS_ORIGINS=https://frontend-peach-xi-69.vercel.app,http://localhost:3000

Critical Auth Server Variables

bash
# Database (auto-set by Railway)
DATABASE_URL=postgresql://...

# Better Auth Secret (REQUIRED)
BETTER_AUTH_SECRET=<random-secret>

# CORS Origins
CORS_ORIGINS=https://frontend-peach-xi-69.vercel.app,https://tda-backend-production.up.railway.app

Health Check Verification

Backend Health Check

bash
curl https://tda-backend-production.up.railway.app/health
# Expected: {"status":"healthy"}

Auth Server Health Check

bash
curl https://auth-server-production-8251.up.railway.app/health
# Expected: {"status":"healthy"}

Database Connectivity

bash
# Check backend logs for:
✅ Using database: postgresql://...
✅ Database connection pool initialized

Common Issues & Solutions

Issue: Deployment Stuck in "Building"

Cause: Build hanging, dependency issues Solution:

bash
claude-code /railway-deploy --service backend --action rollback
# Then check logs to identify build issue

Issue: Service Healthy but Not Responding

Cause: Port configuration, firewall rules Solution: Check Railway service settings, ensure PORT is set correctly

Issue: Environment Variable Not Applied

Cause: Typo in variable name, redeployment needed Solution:

bash
# Re-set variable
claude-code /railway-deploy --service backend --action config --env-vars "VAR_NAME=value" --redeploy

Issue: Database Connection Timeout

Cause: DATABASE_URL incorrect, network issues Solution: Verify DATABASE_URL in Railway, check Neon database status

Deployment Best Practices

1. Pre-Deployment Checklist

  • ✅ All tests passing locally
  • ✅ Dependencies updated
  • ✅ Environment variables documented
  • ✅ Database migrations ready

2. Deployment Steps

bash
# 1. Deploy backend first
claude-code /railway-deploy --service backend --action deploy

# 2. Deploy auth server
claude-code /railway-deploy --service auth-server --action deploy

# 3. Run health checks
claude-code /railway-deploy --service all --action status

# 4. Test authentication flow
claude-code /browser-test-auth --url https://frontend-peach-xi-69.vercel.app

3. Post-Deployment Verification

  • ✅ All services show "Deployed" status
  • ✅ Health checks return 200 OK
  • ✅ Authentication test passes
  • ✅ No errors in logs

4. Rollback Procedure

bash
# If deployment fails:
claude-code /railway-deploy --service backend --action rollback
claude-code /railway-deploy --service backend --action status
# Verify service is working
