How to Trigger Railway Redeploy

There are several ways to trigger a redeployment on Railway. Choose the method that works best for your situation.

Method 1: Push a New Commit (Recommended)

If Railway is connected to your GitHub repository, pushing any commit to the connected branch (usually main) will automatically trigger a redeploy.

# Make a small change or empty commit
git commit --allow-empty -m "Trigger Railway redeploy"
git push origin main

Pros: Simple, uses existing GitHub integration Cons: Creates a commit in history

Method 2: Railway Dashboard (Easiest)

1. Go to Railway Dashboard
2. Select your project
3. Click on your backend service
4. Go to the Deployments tab
5. Click "Redeploy" or "Deploy" button on the latest deployment
6. Or click the "..." menu on any deployment and select "Redeploy"

Pros: No code changes needed, instant Cons: Requires dashboard access

Method 3: Railway CLI

If you have Railway CLI installed:

# Install Railway CLI (if not installed)
npm install -g @railway/cli

# Login to Railway
railway login

# Link to your project (if not already linked)
cd apps/backend
railway link

# Trigger redeploy
railway up

Pros: Command-line control, can be scripted Cons: Requires CLI setup

Method 4: Empty Commit via Git

Create an empty commit to trigger redeploy without code changes:

git commit --allow-empty -m "chore: trigger Railway redeploy"
git push origin main

Pros: Works with GitHub integration, no code changes Cons: Adds commit to history

Method 5: Update Environment Variables

Changing environment variables in Railway dashboard will trigger a redeploy:

1. Go to Railway Dashboard → Your Service → Variables
2. Add, remove, or modify any environment variable
3. Save changes
4. Railway will automatically redeploy

Pros: Useful when you need to update env vars anyway Cons: Changes your environment variables

Method 6: GitHub Actions (If Configured)

If you've set up Railway deployment via GitHub Actions, you can:

1. Go to GitHub → Actions tab
2. Select "Deploy Backend to Railway" workflow
3. Click "Run workflow"
4. Select branch and click "Run workflow"

Pros: Uses CI/CD pipeline Cons: Requires GitHub Actions setup

Troubleshooting

Redeploy Not Triggering?

1. Check GitHub Connection:

   • Railway Dashboard → Project Settings → Source
   • Ensure GitHub repo is connected
   • Check which branch is connected (usually main)

2. Check Service Settings:

   • Railway Dashboard → Your Service → Settings
   • Verify Root Directory is set to apps/backend
   • Check Build Command matches railway.json

3. Check Deployment Logs:

   • Railway Dashboard → Your Service → Deployments
   • Click on latest deployment to see logs
   • Look for errors or build failures

4. Manual Trigger:

   • Use Method 2 (Dashboard) for immediate redeploy
   • Or Method 3 (CLI) if you have it set up

Build Failures

If redeploy fails:

1. Check build logs in Railway dashboard
2. Test build locally first: cd apps/backend && npm run build
3. Fix any errors before redeploying
4. See TESTING_BUILDS.md for build testing

Quick Reference

Fastest Method: Railway Dashboard → Service → Redeploy button

Most Common: Push a commit to main branch

For CI/CD: Use GitHub Actions workflow dispatch

For Automation: Use Railway CLI in scripts

Note: Railway automatically redeploys on every push to the connected branch. If you need to redeploy without code changes, use the dashboard or create an empty commit.
