    # ! Use ${GLOBAL_REGISTRY} for a global registry prefix if defined
    # ! If not pulls from Docker Hub by default, use ${GHCR_REGISTRY} for GitHub Container Registry, etc.
    # ! e.g. ${GLOBAL_REGISTRY:-}httpd:${APACHE_VERSION:-2.4.62-alpine3.20}
    # ! Use ${SERVICE_NAME_VERSION} to specify the image version, e.g., 3.2.1
    image: ${GLOBAL_REGISTRY:-}service-image:${SERVICE_NAME_VERSION:-3.2.1}
    # ! Do not add container_name to allow scaling and avoid name conflicts
