# Build and push multiple Docker images to a registry (GHCR or self-hosted)
# Usage:
#   ./build_and_push_ghcr.sh [TAG]
# Environment variables (defaults shown):
#   TAG (arg or env, default: latest)
#   IMAGE_REGISTRY (default: ghcr.io)
#   OWNER (default: marcopedone)
#   SERVICES (space-separated list, default: backend web db)
#   USERNAME (optional): registry username for docker login
#   TOKEN (optional): registry password/token for docker login
#
# The script expects subfolders for services when building from source:
#  - db -> ./apps/db
#  - backend -> ./apps/backend
#  - web -> ./apps/infoalloggi
