galaxis-po/docker-compose.prod.yml

# Production Docker Compose
# Usage: docker compose -f docker-compose.prod.yml up -d
#
# DB data is stored in a named volume (galaxis-po_postgres_data).
# This survives container recreation and avoids path resolution issues
# when deploying via CI runners with shared Docker sockets.
# To back up: docker exec galaxis-po-db pg_dump -U $DB_USER $DB_NAME > backup.sql
# Volume is only removed with: docker volume rm galaxis-po_postgres_data
