Same with me. I played around with the setup a few times on my local machines. It took quite a bit to get it set up, then I saw an error after a couple of days and gave up. Its easier to just pull down the file and run it locally than use collabora.

I'm not at the same computer I used to look it up, so I don't have my search history, but I think this one was pretty decent. I don't use Traefik, but the rest describes the important bits w/ docker compose. I don't know much about the AIO image though (I used separate images).
