Bare metal cosmos installation is now recommended instead of the docker container. It’s technically still beta, but I’ve been running it since February and very happy with it. The dev has indicated updates will focus on bare metal installation going forward.

I have found it’s made everything vastly easier for me - the marketplace, integrated reverse proxy and URL manager mean you can literally spin many services up with a single click. Yet it has sub-menus for docker env and compose data that allow you to dig deeper into how the containers work if you’re interested in it.
