> Docker image may have ENTRY_POINT predefined, but this is not supported in the current implementation.  It would be nice if we can detect existence of {{launch_command}} and base on this variable launch docker container in different ways:
> h3. Launch command exists
> {code}
> docker run [image]:[version]
> docker exec [container_id] [launch_command]
> {code}
> h3. Use ENTRY_POINT
> {code}
> docker run [image]:[version]
> {code}
