Necessity of `-it --rm` flags when running from docker

[AvantiShri]

Hi, I was trying to run pydesigner on a remote machine via an internal job management system, and was wondering about what happens if the "-it --rm" flags are excluded (the current version of the docs says that we need those flags to "run docker in interative TTY mode"). I ask because my script called the docker container from a shell spawned by python's subprocess module, and because that wasn't a tty shell I had to remove those flags to get the job to run - however, the job has stalled and I am not sure whether it has to do with excluding those flags, so just thought I'd ask in case you have a quick answer.

Thanks, Avanti
