MOUNT: permission on host filesystem

[bendikro]

When issuing MOUNT dir/on/host:/var/cache/yum, the directories dir/on/host are created on the host owned by the root user.

Is there a simple solution to have the dir/on/host including files files and directories created inside this directory to be deletable by the user running rocker build?

Hello, @bendikro! Thanks for your question. I'm not sure, but it seems that it is Docker daemon who creates dir/on/host (not Rocker), and since Docker daemon is run as the root user, files and directories are owned by the root user. So, we need to think whether can do something about this.

Just hit this in the Docker, and it is pretty bad if you run as another user. Looks like something Docker isn't going to fix any time soon.

Braindump:

Tried to think of a solution, but really it makes sense if the volumes are created by the user that ran Rockerfile/Dockerfile anything else is surprising.

Another solution could be new syntax -
Add USERVOLUME syntax to Rockerfile

# create volume /src owned by current host user
USERVOLUME /src
