Hi @<1856869648880898048:profile|CourageousFly32> ,

Is it possible to run an entire docker container from a predefined docker image as a ClearML task (so that it's added to the queue like any other task)?

Yes. You can use the --docker flag in clearml-agent to make it run in agent mode - None

Or is it possible to train remotely using hooks in my MMDetection pipeline?

Can you elaborate?

Any other suggestion or possibilities? Best practices? I have very limited experience with Docker, ClearML and OpenMMLab. Thanks in advance!

I would suggest getting familiarized with Docker concepts and OpenMMLab first. ClearML adds capabilities on top and allows you to manipulate them better.
