Hi everyone!

I’m making a Docker version of my sharing server for ease of use and it works, but I would like to know if there are some “best practices” when it comes to shared folders.

The ‘problem’ is that the docker image is ran as root in its container, and the user runs as the local user, and they both need read/write access to this file.

So my setup is to create a folder where the file will live, created by the local user, and share it with a docker-compose.yml “volumes” command, and have user: “1000:1000” in there as well (with instructions to get the uid & gid).

This has to be done by the user before running the Docker image though, is there a simpler way?

I have seen groups, running docker in userspace and more, but it all seems so cumbersome. I just want a folder where both entities has read & write access.

    You can switch to the user as part of the Dockerfile, somewhere close to the end of it. Assuming uid 1000 is a pretty sane default, people with different setups will have to define themselves.
