Description

It's considered bad practice to run a container's processes as the root user.

Two possible solutions:

1. Give the user the ability to set the container process user and group on container creation
2. Run the process as a non-privileged default user. See linuxserver's implementation where the processes run as user "abc" and the mounted file permissions can be set with environment variables PUID and PGID: https://github.com/linuxserver/docker-plex

Setting the user in a compose file like user: "1068:100" does not work. The container fails to start.
