    # Prefer "1" or "1.x.y" in production.
    #
    # - "1" tracks the latest stable release whose major version is 1
    # - "1.x.y" pins one specific stable version
    # - "latest" moves to each new stable release and may pick up breaking
    #   changes in a future major release, so it is not recommended in production
    # - "edge" tracks the latest unreleased development build
    network_mode: host
    # Optional. This bypasses network isolation and makes IPv6 easier.
    # See "Use IPv6 without sharing the host network".
