Hi Karan, It does not seem to me that launching more mesos containers would add more overheads.
If you want to achieve *docker exec* for debugging purpose, Mesos supports that (not in Mesos CLI yet /cc Armand and Kevin), but you could still rely on dc/os CLI <https://docs.mesosphere.com/1.11/monitoring/debugging/task-exec/> to do that given you have the taskId.
