Railway Deployment Management

Complete deployment workflows for Railway.com including deployment from multiple sources, rollback strategies, health verification, and staging-to-production promotion.

Overview

This skill provides comprehensive deployment management for Railway:

  • Deploy from sources: GitHub auto-deploy, Docker images, local directory
  • Monitor deployments: Real-time logs, status tracking, build progress
  • Verify health: Automated health checks and validation
  • Rollback strategies: Safe rollback to previous deployments
  • Environment management: Staging → production workflows
  • CI/CD integration: Automated deployment pipelines

Prerequisites

  • Railway CLI installed and authenticated (use railway-auth skill)
  • Project linked (use railway-project-management skill)
  • Service created in target environment

When to Use

  • Deploying new code to Railway
  • Redeploying after configuration changes
  • Rolling back failed deployments
  • Promoting staging to production
  • Setting up automated deployments
  • Monitoring deployment progress
  • Verifying deployment health

5-Step Deployment Workflow

Step 1: Prepare Deployment

Verify authentication, project context, and service health before deploying.

Commands:

# Verify authentication
railway whoami

# Check project and environment context
railway status

# List services in current environment
railway list

# Check current deployment status
railway status --json

Pre-deployment checklist:

  • Authenticated with Railway
  • Correct project linked
  • Target environment selected
  • Service exists in environment
  • No pending deployments
  • Environment variables set

Use automation:

.claude/skills/railway-deployment/scripts/pre-deploy-check.sh

Step 2: Deploy

Deploy from GitHub, Docker, or local directory.

Deploy from GitHub (Auto-Deploy)

Setup auto-deploy:

# Link service to GitHub repo
railway add --repo owner/repository

# Configure branch (via dashboard or railway.json)
railway open

Trigger deployment:

# Push to configured branch
git push origin main

# Railway automatically deploys
# Monitor in real-time:
railway logs --deployment

Manual redeploy:

# Redeploy latest commit
railway redeploy

# Redeploy specific deployment ID
railway redeploy --deployment <deployment-id>

Deploy from Local Directory

Deploy current directory:

# Deploy and wait for completion
railway up

# Deploy without waiting (detached)
railway up --detach

# Deploy in CI mode (build logs only)
railway up --ci

# Deploy specific service
railway up --service backend

What happens:

  1. CLI uploads local directory to Railway
  2. Railway detects build configuration (Nixpacks/Dockerfile)
  3. Build starts automatically
  4. Deployment triggers on successful build
  5. Service restarts with new code

Deploy from Docker Image

Public image:

# Deploy Docker Hub image
railway add --image postgres:15

# Deploy with tag
railway add --image myapp/backend:v1.2.3

Private registry:

# Set registry credentials
railway variables set --sealed DOCKER_USERNAME=user
railway variables set --sealed DOCKER_PASSWORD=pass

# Deploy from private registry
railway add --image registry.example.com/app:latest

Update image tag (rollback/upgrade):

# Via environment variable
railway variables set IMAGE_TAG=v1.2.2

# Force redeploy with new tag
railway redeploy

See references/deployment-sources.md for detailed configuration.

Step 3: Monitor Deployment

Track deployment progress and identify issues in real-time.

Real-time logs:

# Follow deployment logs
railway logs --deployment

# Filter by service
railway logs --service backend --deployment

# Show last 100 lines
railway logs --tail 100

# Include timestamps
railway logs --timestamps

Deployment status:

# Check deployment status
railway status

# Get detailed JSON status
railway status --json | jq '.deployments[0]'

# List recent deployments
railway list deployments

# Check specific deployment
railway deployment <deployment-id>

Build progress indicators:

Building... ████████░░░░░░░░ 60%
Installing dependencies...
Running build script...
Optimizing assets...

Watch for issues:

  • Build failures (missing dependencies)
  • Environment variable errors
  • Port binding issues
  • Memory/CPU limits exceeded
  • Health check failures

Automated monitoring:

# Monitor and alert on failures
.claude/skills/railway-deployment/scripts/monitor-deployment.sh

Step 4: Verify Deployment

Validate that deployment is healthy and functioning correctly.

Health check commands:

# Check service health endpoint
curl https://your-service.railway.app/health

# Verify with custom validation
.claude/skills/railway-deployment/scripts/verify-health.sh

Validation checklist:

  • Service is running (not crashed)
  • Health endpoint returns 200 OK
  • Environment variables loaded correctly
  • Database connections established
  • API endpoints responding
  • Static assets loading
  • No error logs present

Automated validation:

# Run full health check suite
.claude/skills/railway-deployment/scripts/deploy.sh --verify

# Output:
# ✅ Service running
# ✅ Health check passed (200 OK)
# ✅ Environment variables loaded
# ✅ Database connection successful
# ✅ API responding correctly

Common validation issues:

Issue Symptom Solution
Service not starting Status: "crashed" Check logs for startup errors
Health check failing 503 Service Unavailable Verify health endpoint path
Variables missing Application errors Check railway variables list
Port binding error "EADDRINUSE" Ensure PORT variable used
Database connection "ECONNREFUSED" Verify DATABASE_URL set

Step 5: Rollback if Needed

Safely rollback to previous deployment if issues are detected.

Quick rollback:

# Redeploy previous deployment
railway redeploy --deployment <previous-deployment-id>

# List recent deployments to find ID
railway list deployments

Automated rollback:

# Rollback with safety checks
.claude/skills/railway-deployment/scripts/rollback.sh

# Rollback to specific version
.claude/skills/railway-deployment/scripts/rollback.sh v1.2.3

Rollback strategies:

  1. Redeploy Previous Commit (GitHub):

    # Find previous working commit
git log --oneline

# Revert to previous commit
git revert HEAD
git push origin main

# Railway auto-deploys

  2. Redeploy Previous Deployment (any source):

    # List deployments
railway list deployments

# Redeploy specific deployment ID
railway redeploy --deployment dep_abc123xyz

  3. Docker Image Tag Rollback:

    # Update image tag to previous version
railway variables set IMAGE_TAG=v1.2.2

# Redeploy with previous tag
railway redeploy

  4. Environment Variable Rollback:

    # Restore previous variable values
railway variables set API_VERSION=v1
railway variables set FEATURE_FLAGS=old-config

# Redeploy with previous config
railway redeploy

See references/rollback-strategies.md for detailed rollback procedures.

Rollback verification:

# After rollback, verify health
.claude/skills/railway-deployment/scripts/verify-health.sh

# Check logs for errors
railway logs --tail 50

# Verify specific functionality
curl https://your-service.railway.app/api/test

Staging → Production Workflow

Typical promotion flow:

# 1. Deploy to staging first
railway environment staging
railway up

# 2. Verify staging deployment
.claude/skills/railway-deployment/scripts/verify-health.sh

# 3. Run staging tests
npm run test:staging

# 4. Promote to production
railway environment production

# 5. Deploy same code
railway up

# 6. Verify production
.claude/skills/railway-deployment/scripts/verify-health.sh

# 7. Monitor production logs
railway logs --deployment

Automated staging workflow:

# Complete staging → production workflow
.claude/skills/railway-deployment/scripts/promote-to-production.sh

See references/staging-workflow.md for detailed staging strategies.

Advanced Deployment Patterns

Blue-Green Deployment

# 1. Deploy to "green" environment
railway environment green
railway up

# 2. Verify green is healthy
.claude/skills/railway-deployment/scripts/verify-health.sh

# 3. Switch traffic to green
# (Update DNS or load balancer)

# 4. Keep blue as rollback option
railway environment blue
# (Don't delete until green is stable)

Canary Deployment

# 1. Deploy canary version
railway environment canary
railway up

# 2. Route small % of traffic to canary
# (Configure via load balancer)

# 3. Monitor canary metrics
railway logs --service canary

# 4. Gradually increase traffic
# (Adjust load balancer weights)

# 5. Promote to production if successful
railway environment production
railway up

Rolling Deployment

# Deploy to instances one at a time
# (Requires horizontal scaling)

# Railway handles rolling deploys automatically
# when multiple replicas are configured
railway up

# Monitors health and rolls back on failure

Deployment Troubleshooting

Build Failures

# Check build logs
railway logs --deployment

# Common issues:
# - Missing package.json
# - Node/Python version mismatch
# - Build command failures
# - Environment variables not set

# Fix and redeploy
railway up

Deployment Stuck

# Check deployment status
railway status --json

# Cancel stuck deployment
railway deployment cancel <deployment-id>

# Redeploy
railway up

Health Check Failures

# Check service logs
railway logs

# Verify health endpoint exists
curl -v https://your-service.railway.app/health

# Check port configuration
railway variables list | grep PORT

# Verify restart policy
railway open  # Check service settings

Memory/CPU Limits

# Check resource usage
railway metrics

# Increase limits (via dashboard)
railway open

# Or upgrade plan
