I keep my server config in a public git repo, but I don't think you have to do anything really special to make it work with lemmy. Since I use Traefik I followed the guide for setting up Anubis with Traefik.

I don't expect to run into issues as Anubis specifically looks for user-agent strings that appear like human users (i.e. they contain the word "Mozilla" as most graphical web browsers do) any request clearly coming from a bot that identifies itself is left alone, and lemmy identifies itself as "Lemmy/{version} +{hostname}" in requests.
