It's kind of my job to take random apps, deploy them and manage properly, so I'm not a clueless user here. I could press on and figure it out with more time, and I understand they'd be happy with people using the cloud offering / paid support instead. But I also feel like a working docker-compose (or comparable) setup is table stakes these days for an open-source service.
See Loki+Grafana for a good example: https://grafana.com/docs/loki/latest/installation/docker/#in... - it's not a production setup, but it's a valid "play around with it in 2min" setup.
