# Staging Environment Override
# Usage: docker-compose -f docker-compose.base.yml -f docker-compose.staging.yml up
#
# This file overrides base configuration with staging-specific settings:
# - Container names with "staging-" prefix
# - Traefik integration for staging.michaelschiemer.de
# - Git clone functionality for staging branch
# - Staging-specific networks (traefik-public, staging-internal)
# - Staging-specific volumes
