do not use root user

[runningman84]

I think this container would also run just fine if it would run as user nobody. I would advice to add a user directive to the Dockerfile.

Yes. That's totally right. Would you like to update the documentation?

I can send you a pull request for the Dockerfile. I would also add tini as an entrypoint which is also best practice.
