# Production Environment Override
# Usage: docker-compose -f docker-compose.base.yml -f docker-compose.prod.yml up
#
# This file configures services for production deployment:
# - Production-specific service names (production-*)
# - Private registry images (localhost:5000/framework:latest)
# - Git-based code deployment from main branch
# - Traefik integration for michaelschiemer.de domain
# - PostgreSQL connection via postgres-production-internal network
# - Production-grade resource limits and security settings
# - Docker Secrets for sensitive configuration
