    # Step 3 (Part 1):
    # A container will be setup for each job, and each step will
    # be executed in it.
    # This DOCKER_HOST environment variable will be used at each exec
    # in that container, like docker exec -e DOCKER_HOST=tcp://dind_container.docker.internal:2375 <command>
    # When you run the docker CLI or related
    # commands, they'll find this variable and reach out to the DIND
    # container to perform work there.
    DOCKER_HOST: tcp://dind_container.docker.internal:2375
