The concept from this has been incorporated into my docker-base repo: https://github.com/sudo-bmitch/docker-base/blob/master/bin/fix-perms
Run As User
This is an example for how to run Docker containers as the user on the host.
To use this example, mount a volume in your container at /home/myuser. The entrypoint will automatically adjust permissions of the current user and then drop down to running as that user, executing the requested command.
docker build -t run-as-user .
docker run -it --rm -v $(pwd):/home/myuser run-as-user /bin/bash
Inside that container, you can run id and ls -l to see your permisisons
matching that of /home/myuser.
