Deployment Checklist and Next Steps

This document provides a checklist for deploying the multi-tenant POP3 Forwarder with web interface.

🚀 Pre-Deployment Checklist

1. Environment Setup

Backend Environment Variables (backend/.env)

• Generate secure SECRET_KEY (min 32 characters)

  openssl rand -hex 32
  

• Generate secure ENCRYPTION_KEY (min 32 characters)

  openssl rand -hex 32
  

• Set DATABASE_URL to production PostgreSQL instance
• Configure REDIS_URL for production Redis
• Set CORS_ORIGINS to include production frontend URL
• Set DEBUG=false for production
• Configure LOG_LEVEL=INFO or WARNING

Google OAuth (Optional but Recommended)

• Create Google Cloud Project
• Enable Google+ API
• Create OAuth 2.0 credentials
• Set authorized redirect URIs:
  • Development: http://localhost:3000/auth/callback
  • Production: https://yourdomain.com/auth/callback
• Add GOOGLE_CLIENT_ID to backend/.env
• Add GOOGLE_CLIENT_SECRET to backend/.env
• Add GOOGLE_REDIRECT_URI to backend/.env

Frontend Environment Variables (frontend/.env.local)

• Set NEXT_PUBLIC_API_URL to backend URL
  • Development: http://localhost:8000
  • Production: https://api.yourdomain.com

2. Infrastructure Setup

Docker Host

• Server with Docker installed (20.10+)
• Docker Compose installed (v2.0+)
• Minimum 2 vCPU, 4GB RAM
• 40GB+ available disk space
• Ports 80, 443, 8000, 3000 available

Database

• PostgreSQL 15+ instance running
• Database created: pop3_forwarder
• Connection details configured in backend/.env
• Backups configured

Redis

• Redis 7+ instance running
• Connection details configured in backend/.env
• Persistence enabled (AOF or RDB)

3. SSL/TLS Configuration

Option A: Let's Encrypt with Certbot

sudo apt-get install certbot python3-certbot-nginx
sudo certbot --nginx -d yourdomain.com -d api.yourdomain.com

Option B: Reverse Proxy (Recommended)

• nginx or Traefik configured
• SSL certificates obtained
• Frontend proxied from port 3000
• Backend API proxied from port 8000
• CORS headers properly configured

4. Security Hardening

• Firewall configured (UFW or iptables)
• Only necessary ports open (80, 443, 22)
• SSH key-based authentication
• Fail2ban installed for brute force protection
• Docker containers running as non-root users
• Secrets not committed to version control
• Regular security updates enabled

📦 Deployment Steps

Step 1: Clone Repository

# On production server
cd /opt
sudo git clone https://github.com/christianlouis/pop_puller_to_gmail.git
cd pop_puller_to_gmail

Step 2: Configure Environment

# Backend
cd backend
cp .env.example .env
nano .env  # Edit with production values

# Frontend
cd ../frontend
echo "NEXT_PUBLIC_API_URL=https://api.yourdomain.com" > .env.local

Step 3: Build and Start Services

cd ..
docker-compose -f docker-compose.new.yml build
docker-compose -f docker-compose.new.yml up -d

Step 4: Initialize Database

# Run migrations
docker-compose -f docker-compose.new.yml exec backend alembic upgrade head

# Verify
docker-compose -f docker-compose.new.yml exec backend alembic current

Step 5: Verify Services

# Check all services are running
docker-compose -f docker-compose.new.yml ps

# Check logs
docker-compose -f docker-compose.new.yml logs -f

Step 6: Test Application

# Test backend API
curl https://api.yourdomain.com/health

# Test frontend
curl https://yourdomain.com

# Register test user
curl -X POST https://api.yourdomain.com/api/v1/auth/register \
  -H "Content-Type: application/json" \
  -d '{"email":"test@example.com","password":"testpass123","full_name":"Test User"}'

Step 7: Configure Monitoring

Health Checks

# Add to crontab for monitoring
*/5 * * * * curl -f https://yourdomain.com/health || mail -s "Site Down" admin@yourdomain.com

Log Rotation

# Configure Docker log rotation in /etc/docker/daemon.json
{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "3"
  }
}

🔄 Maintenance

Regular Tasks

Daily

• Monitor error logs
• Check Celery worker status
• Verify email processing is working

Weekly

• Review database size and performance
• Check for security updates
• Rotate logs if necessary

Monthly

• Database backup verification
• Review user feedback and errors
• Update dependencies if needed

Backup Strategy

Database Backups

# Automated daily backup script
cat > /usr/local/bin/backup-pop3-db.sh << 'EOF'
#!/bin/bash
BACKUP_DIR=/var/backups/pop3_forwarder
DATE=$(date +%Y%m%d_%H%M%S)
docker exec pop3-postgres pg_dump -U postgres pop3_forwarder | gzip > $BACKUP_DIR/backup_$DATE.sql.gz
find $BACKUP_DIR -type f -mtime +30 -delete
EOF

chmod +x /usr/local/bin/backup-pop3-db.sh

# Add to crontab
0 2 * * * /usr/local/bin/backup-pop3-db.sh

🐛 Troubleshooting

Common Issues

Frontend Cannot Connect to Backend

Symptoms: CORS errors, network errors Solutions:

1. Verify CORS_ORIGINS includes frontend URL
2. Check backend is accessible from frontend container
3. Verify API URL in frontend .env.local

Database Connection Errors

Symptoms: "Connection refused" or timeout errors Solutions:

1. Check PostgreSQL is running
2. Verify DATABASE_URL is correct
3. Check network connectivity
4. Review PostgreSQL logs

Celery Workers Not Processing

Symptoms: Emails not being forwarded Solutions:

1. Check Redis is running
2. Review celery-worker logs
3. Verify CELERY_BROKER_URL is correct
4. Restart celery-worker container

OAuth Not Working

Symptoms: "Invalid redirect URI" or OAuth errors Solutions:

1. Verify GOOGLE_REDIRECT_URI matches exactly
2. Check OAuth credentials in Google Console
3. Ensure HTTPS is used in production

Log Locations

# Backend logs
docker-compose -f docker-compose.new.yml logs backend

# Frontend logs
docker-compose -f docker-compose.new.yml logs frontend

# Celery worker logs
docker-compose -f docker-compose.new.yml logs celery-worker

# Database logs
docker-compose -f docker-compose.new.yml logs postgres

📊 Monitoring & Observability

Recommended Tools

Application Monitoring

• Uptime Monitoring: UptimeRobot, Pingdom
• Error Tracking: Sentry (can be added to backend)
• Performance: New Relic, DataDog

Infrastructure Monitoring

• Container Health: Docker healthchecks
• Resource Usage: cAdvisor + Prometheus + Grafana
• Log Aggregation: ELK Stack or Loki

Metrics to Monitor

• API response times
• Error rates
• Email processing throughput
• Database connection pool usage
• Redis memory usage
• Disk space utilization
• Container CPU/Memory usage

🔐 Security Considerations

Ongoing Security Tasks

• Regular dependency updates

  # Backend
  cd backend
  pip list --outdated
  
  # Frontend
  cd frontend
  npm outdated
  

• Monitor for security advisories

  • GitHub Dependabot alerts
  • CVE databases
  • Security mailing lists

• Regular security audits
