Description of errors

I currently play around and try to get a working docker containter. I'm a selfhoster which is interested in do things my own way. While doing this I also learn. But geting a working Dockerfile and compose file was hard work in this case.

To help user get along, I propose to publish a working example with a GPU using application.
Create a working Dockerfile and a compose file.

I propose to either start or end eg. here How To Guide with such an example

Attach any links, screenshots, or additional evidence you think will be helpful.
