Thank you for your interest in HTCondor and Docker Universe -- this is an interesting use case for us.

This is correct, that the Docker universe in condor currently doesn't create GPU devices in the container.

One quick workaround might be to have docker run map all of the GPU devices inside the container, and rely on the Condor fungible custom resources code to set the nvidia environment variable appropriate for the selected GPU(s). Would this work for your needs?
