I'm a minor contributor to mbrubeck's excellent Agate Gemini protocol server, and also wanted to make it available to folks on their Unraid servers.
As the person who helped ship Agate as a docker container, I'll happily offer what support I can on running that container on Unraid here.
(Note: I'm new to contributing apps to Unraid, so I'm posting this before the app is available in Community Applications! PR here)
