        #     container's [`CMD`](https://docs.docker.com/engine/reference/builder/#cmd),
        #     if either exists. If this field is not specified and the container does not

        #     If you don't specify this field but do specify the

        #
        #     If you don't specify this field and don't specify the `command` field,
