docker container user ID issue

[seibert]

It looks like the /home/mpi/shad directory in the quickstart docker images is mounted from the host filesystem, which causes problems following the guide if the host user ID doesn't happen to match the mpi user ID in the container (which is 1000).

It isn't clear to me if there is a good solution for this in Docker (though there are many clunky workarounds proposed on StackOverflow), but at least a note in the README would help users realize what is going on. (I misdiagnosed the problem the first time.) A user workaround would be to ask them to make the host shad directory writeable by all users when testing these containers.

Hello @seibert, honestly it never happened to me :-). It works on my work laptop where I have the ID assigned by our IT. Which system do you have? I would like to reproduce it so that I can try to put a reasonable fix.

Can you provide me os version and docker version?

Thanks!
