# Production Environment Override
# Usage: docker-compose -f docker-compose.base.yml -f docker-compose.production.yml --env-file .env.production up -d
#
# This file overrides base configuration with production-specific settings:
# - Stricter resource limits
# - Production restart policies (always)
# - JSON logging with proper rotation
# - No host mounts (security)
# - Production PostgreSQL configuration
# - Certbot for SSL certificates
# - Production port mappings (80, 443 for Let's Encrypt)
