    # When using dind service we need to instruct docker, to talk with the
    # daemon started inside of the service. The daemon is available with
    # a network connection instead of the default /var/run/docker.sock socket.
    #
    # The 'docker' hostname is the alias of the service container as described at
    # https://docs.gitlab.com/ee/ci/docker/using_docker_images.html#accessing-the-services
    #
    # Note that if you're using Kubernetes executor, the variable should be set to
    # tcp://localhost:2375 because of how Kubernetes executor connects services
    # to the job container
    DOCKER_HOST: tcp://docker:2375/
    # When using dind, it's wise to use the overlayfs driver for
    # improved performance.
