Review Comment:
Thanks @smengcl for the review.
> whoever calls `start_docker_env` **_last_** would have to call
`stop_docker_env` in order to have the logs collected
It's like a `ShutdownHook` in Java. The shell calls `stop_docker_env` when
the test script exits. `start_docker_env` just sets it up.
