Implements comprehensive Docker containerization for the entire VIP Coordinator application, enabling single-command production deployment. Backend Containerization: - Multi-stage Dockerfile (dependencies → builder → production) - Automated database migrations via docker-entrypoint.sh - Health checks and non-root user for security - Optimized image size (~200-250MB vs ~500MB) - Includes OpenSSL, dumb-init, and netcat for proper operation Frontend Containerization: - Multi-stage Dockerfile (builder → nginx) - Nginx configuration with SPA routing and API proxying - Security headers and gzip compression - Optimized image size (~45-50MB vs ~450MB) - Health check endpoint at /health Infrastructure: - docker-compose.prod.yml orchestrating 4 services: * PostgreSQL 16 (database) * Redis 7 (caching) * Backend (NestJS API) * Frontend (Nginx serving React SPA) - Service dependencies with health check conditions - Named volumes for data persistence - Dedicated bridge network for service isolation - Comprehensive logging configuration Configuration: - .env.production.example template with all required variables - Build-time environment injection for frontend - Runtime environment injection for backend - .dockerignore files for optimal build context Documentation: - Updated README.md with complete Docker deployment guide - Quick start instructions - Troubleshooting section - Production enhancement recommendations - Updated project structure diagram Deployment Features: - One-command deployment: docker-compose up -d - Automatic database migrations on backend startup - Optional database seeding via RUN_SEED flag - Rolling updates support - Zero-config service discovery - Health checks prevent premature traffic Image Optimizations: - Backend: 60% size reduction via multi-stage build - Frontend: 90% size reduction via nginx alpine - Total deployment: <300MB (excluding volumes) - Layer caching for fast rebuilds Security Enhancements: - Non-root users in all containers - Minimal attack surface (Alpine Linux) - No secrets in images (runtime injection) - Health checks ensure service readiness Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
