I was able to get it running with the docker compose CA app and minimal changes to the official docker-compose file (docs). I’m running swag in front of the lemmy proxy with no issues with federation. Ibracorp’s tutorial can help with the compose plugin
You’ll need to make sure the volume locations and ports are appropriate for your unraid install. You’ll also have to update your domain in the compose file. I’m running swag so I needed to make a new reverse proxy configuration per the official docs.
My compose file is below:
