using elpy here with a native install and can use e.g. tramp for remote editing/python sessions in most cases (even across machines), but determining docker mount points to edit in-machine not so much..

I suppose one can simply map a local code directory into a runtime environment, but this also makes e.g. interacting with an in-container interpreter a bit bothersome (not so bad actually, but have to set a separate interpreter path to something like 'docker exec -it ctid python'

would like to track this down I suppose
