Sure, I can take a look, I'd love to get this running. I'm not familiar with these, but I've got LLM on my side.

you would want to replace the host settings (line 28) with your domain/subdomain. Starting both services should be fine. Also I reduced the size of the final docker image.
I'm going to look into that, I think I need to learn docker. For now I have it successfully connecting over wss! Except it just gives errors. OK 😅
