Production Deployment

This section covers production deployment strategies for LUStores, including SSL/HTTPS setup, monitoring, and best practices.

Overview

Production deployment involves several key components:

  • SSL/HTTPS Configuration: Secure transport with Let’s Encrypt

  • Container Orchestration: Docker Compose for multi-service deployment

  • Database Management: PostgreSQL with backup and monitoring

  • Reverse Proxy: Nginx for SSL termination and load balancing

  • Monitoring & Logging: Comprehensive system monitoring

Quick Start

For a complete production deployment with SSL/HTTPS:

# Clone and setup
git clone https://github.com/st7ma784/LUStores.git
cd LUStores

# Configure SSL/HTTPS (see SSL/HTTPS guide for details)
export DOMAIN="inventory.university.edu"
export EMAIL="admin@university.edu"
make ssl-setup DOMAIN=$DOMAIN EMAIL=$EMAIL

# Deploy production services
make ssl-prod

# Verify deployment
curl -I https://$DOMAIN/health

SSL/HTTPS Setup

For comprehensive SSL/HTTPS configuration including:

  • Let’s Encrypt certificate management

  • Nginx reverse proxy setup

  • Security headers and rate limiting

  • Certificate auto-renewal

  • Troubleshooting and monitoring

See the complete guide: SSL/HTTPS Configuration

Container Deployment

The system uses Docker Compose for orchestrating multiple services:

services:
  nginx:      # SSL termination, reverse proxy
  app:        # Node.js/Express application
  db:         # PostgreSQL database
  redis:      # Session storage and caching
  certbot:    # Let's Encrypt certificate management

Production services are configured in: - docker-compose.yml - Base configuration - docker-compose.prod.yml - Production overrides with SSL

Database Management

Production database considerations:

  • Persistent Volumes: Data persistence across container restarts

  • Backup Strategy: Automated backups with retention policies

  • Connection Pooling: Optimized database connections

  • Monitoring: Database performance and health checks

Environment Configuration

Critical environment variables for production:

# Core Application
NODE_ENV=production
DATABASE_URL=postgresql://user:pass@db:5432/university_inventory
SESSION_SECRET=your-secure-session-secret

# SSL/HTTPS
HTTPS=true
FORCE_HTTPS=true
DOMAIN=inventory.university.edu

# OAuth Integration
ISSUER_URL=https://your-oauth-provider.edu/oidc
CLIENT_ID=your-client-id
CLIENT_SECRET=your-client-secret

Load Balancing

For high-availability deployments:

  1. Application Load Balancer: Multiple app instances behind load balancer

  2. Database Clustering: PostgreSQL primary/replica configuration

  3. Session Persistence: Redis cluster for shared session storage

  4. Static Asset CDN: Content delivery network for performance

Security Hardening

Production security checklist:

  • [ ] SSL/HTTPS enabled with strong ciphers

  • [ ] Security headers configured (HSTS, CSP, etc.)

  • [ ] Rate limiting active

  • [ ] Firewall configured (only ports 80, 443 open)

  • [ ] Regular security updates applied

  • [ ] Database access restricted

  • [ ] Secrets managed securely (not in environment files)

Deployment Monitoring

The System Management API provides comprehensive deployment status monitoring:

  • Health Checks: Service availability and status

  • Performance Metrics: Response times, throughput, errors

  • Certificate Monitoring: SSL certificate expiration alerts

  • Database Monitoring: Connection pool, query performance

  • Resource Usage: CPU, memory, disk utilization

For monitoring setup: Monitoring

Backup and Recovery

Production backup strategy:

Database Backups: - Automated daily backups - Point-in-time recovery capability - Encrypted backup storage - Regular restore testing

Application Backups: - Configuration files - SSL certificates - Log files - User uploads (if any)

Recovery Procedures: - Documented rollback procedures - Database restore processes - Certificate recovery - Service restart protocols

Testing Production Deployments

Production deployment testing is covered in the comprehensive test suite:

  • End-to-End Tests: Full user workflows

  • Integration Tests: Service communication

  • Performance Tests: Load and stress testing

  • Security Tests: Vulnerability scanning

See ../testing-guide for complete testing procedures.

Maintenance and Updates

Regular maintenance tasks:

Security Updates: - Container base image updates - Node.js security patches - Database updates - SSL certificate renewal (automated)

Performance Optimization: - Database query optimization - Cache tuning - Resource scaling - Log rotation

Monitoring Review: - Performance metrics analysis - Error rate monitoring - Capacity planning - Alert threshold tuning

Troubleshooting

Common production issues and solutions:

Service Start Failures: - Check Docker container logs - Verify environment variables - Confirm database connectivity - Check SSL certificate validity

Performance Issues: - Monitor resource utilization - Check database query performance - Review nginx access logs - Analyze application metrics

SSL/HTTPS Problems: - Verify certificate validity - Check nginx configuration - Test Let’s Encrypt renewal - Review DNS configuration
