@ironoxidizer put the image on docker hub, so its not necessary to compile manually anymore. I also added Lemmy Lite to the Ansible deployment, and to the federation setup. You can test it under https://test.lemmy.ml/lite (s.css is loaded from the wrong location so its broken). You can also try it by running docker/federation/start-local-instances.bash and going to localhost:8540/lite.
Still need to update docker/prod/docker-compose.yml.
