🚀 Railway App Replacement Deployment Guide

Overview

This guide provides step-by-step instructions to replace your current Railway deployment with this enhanced Quantum Tasks AI version.

Pre-Deployment Checklist

✅ What's Ready in Enhanced Version

  • 6 AI Agents: Data Analyzer, Weather Reporter, Job Posting Generator, Social Ads Generator, Five Whys Analyzer, Email Writer
  • Production Configuration: Optimized railway.json with Gunicorn settings
  • Database Schema: All migrations ready and tested
  • Static Files: WhiteNoise configuration for production
  • Health Endpoint: /health/ for monitoring and load balancers

  • Component Architecture: Consistent UI/UX across all agents

Step 1: Environment Variables Preparation (15 minutes)

1.1 Export Current Production Variables

  1. Go to your existing Railway project dashboard
  2. Navigate to Variables tab
  3. Export/copy these variables: 
    SECRET_KEY=your_current_secret_key
STRIPE_SECRET_KEY=your_stripe_secret_key
STRIPE_WEBHOOK_SECRET=your_webhook_secret
EMAIL_HOST_USER=your_email@gmail.com
EMAIL_HOST_PASSWORD=your_app_password
N8N_WEBHOOK_DATA_ANALYZER=your_n8n_url
N8N_WEBHOOK_FIVE_WHYS=your_n8n_url
N8N_WEBHOOK_JOB_POSTING=your_n8n_url
N8N_WEBHOOK_SOCIAL_ADS=your_n8n_url
OPENWEATHER_API_KEY=your_api_key

1.2 Verify Required Variables

Ensure you have all variables from RAILWAY_ENV_TEMPLATE.md:

  • ✅ Core security settings (SECRET_KEY, DEBUG=False, ALLOWED_HOSTS)
  • ✅ Email configuration (Gmail SMTP)
  • ✅ Stripe payment configuration (live keys)
  • ✅ N8N webhook URLs (external server)
  • ✅ OpenWeather API key

Step 2: Database Backup (10 minutes)

2.1 Create Database Backup

# From your current Railway project, create a backup
railway login
railway link your-current-project-id
railway run pg_dump $DATABASE_URL > quantum_ai_backup.sql

2.2 Download Backup File

# Download the backup to local machine
railway volume:list
railway run cat quantum_ai_backup.sql > local_backup.sql

Step 3: Deploy Enhanced Version (20 minutes)

3.1 Create New Railway Project (or Update Existing)

Option A: Replace in Same Project (Recommended)

# Clone this enhanced repository
git clone your-enhanced-repo-url
cd quantum_ai

# Link to your existing Railway project
railway login
railway link your-existing-project-id

# Deploy enhanced version
git add .
git commit -m "Deploy enhanced Quantum Tasks AI version"
git push origin main
railway up

Option B: Create New Project

# Create new Railway project
railway login
railway init
railway add postgresql
railway add redis  # Optional but recommended

# Deploy enhanced version
railway up

3.2 Set Environment Variables

In Railway dashboard, set all variables from Step 1.1:

# Core Settings
SECRET_KEY=your_production_secret_key
DEBUG=False
ALLOWED_HOSTS=your-domain.railway.app,quantumtaskai.com
CSRF_TRUSTED_ORIGINS=https://your-domain.railway.app,https://quantumtaskai.com

# Email Configuration
EMAIL_BACKEND=django.core.mail.backends.smtp.EmailBackend
EMAIL_HOST_USER=your-email@gmail.com
EMAIL_HOST_PASSWORD=your-16-char-app-password
DEFAULT_FROM_EMAIL=Quantum Tasks AI <noreply@quantumtaskai.com>

# Stripe Configuration
STRIPE_SECRET_KEY=sk_live_your_live_key
STRIPE_WEBHOOK_SECRET=whsec_your_webhook_secret

# N8N Webhooks (External Server URLs)
N8N_WEBHOOK_DATA_ANALYZER=https://your-n8n.app.n8n.cloud/webhook/data-analyzer
N8N_WEBHOOK_FIVE_WHYS=https://your-n8n.app.n8n.cloud/webhook/five-whys
N8N_WEBHOOK_JOB_POSTING=https://your-n8n.app.n8n.cloud/webhook/job-posting
N8N_WEBHOOK_SOCIAL_ADS=https://your-n8n.app.n8n.cloud/webhook/social-ads

# External APIs
OPENWEATHER_API_KEY=your_openweather_key

Step 4: Database Migration (10 minutes)

4.1 Automatic Migration

Railway deployment automatically runs:

python manage.py migrate --fake-initial || python manage.py migrate
python manage.py populate_agents
python manage.py collectstatic --noinput

4.2 Verify Database Setup

Check Railway deployment logs for:

  • ✅ Migrations applied successfully
  • ✅ Agents populated (6 agents created/updated)
  • ✅ Static files collected
  • ✅ Gunicorn server started

Step 5: Post-Deployment Verification (15 minutes)

5.1 Health Check

curl https://your-domain.railway.app/health/

Expected response:

{
  "status": "healthy",
  "checks": {
    "database": {"status": "healthy", "response_time_ms": 2.5},
    "agents": {"status": "healthy", "active_count": 6}
  }
}

5.2 Core Functionality Tests

  1. Homepage: Visit https://your-domain.railway.app/
  2. User Registration: Create test account
  3. Agent Marketplace: Visit /marketplace/
  4. Payment System: Test wallet top-up with Stripe test card
  5. AI Agents: Test at least 2 agents end-to-end

5.3 Agent-Specific Testing

  • Weather Reporter: Test with a city name
  • Data Analyzer: Upload a CSV file
  • Email Writer: Generate a test email
  • Job Posting Generator: Create a sample job posting
  • Social Ads Generator: Generate social media ad
  • Five Whys Analyzer: Analyze a problem scenario

Step 6: DNS & Domain Configuration (5 minutes)

6.1 Update Domain Settings

If using custom domain (quantumtaskai.com):

  1. Update DNS CNAME record to point to new Railway URL
  2. Verify SSL certificate renewal
  3. Test domain accessibility

6.2 Update External Service Configurations

  1. Stripe Webhooks: Update webhook URL if changed
  2. Email Services: Verify SMTP configuration
  3. N8N Workflows: Ensure webhook URLs are accessible

Step 7: Monitoring & Alerts (5 minutes)

7.1 Set Up Monitoring

  1. Configure uptime monitoring for /health/ endpoint
  2. Set up Railway project alerts
  3. Monitor application logs for errors
  4. Set up email alerts for critical issues

7.2 Performance Baseline

  • Monitor initial response times
  • Check database query performance
  • Verify static file loading speed
  • Monitor memory and CPU usage

Rollback Plan (If Issues Occur)

Immediate Rollback Options

  1. Environment Variables: Quickly disable new features
  2. Railway Rollback: Use Railway's deployment history
  3. Database Restore: Restore from Step 2 backup
  4. DNS Rollback: Point domain back to old deployment

Emergency Commands

# Rollback to previous deployment
railway rollback

# Restore database from backup
railway run psql $DATABASE_URL < local_backup.sql

# Disable problematic features
railway variables:set DEBUG=True  # Temporary for debugging
