And the production infra for running isn't even available, just a pared down "development server" via SSPL. This is a long way from OSS.
Earlier this year we didn't want folks to roll their own production cloud due to queueing migrations. It would make your life hard. We're entirely responsible for that right now, as we discouraged self hosting.
That's actually coming to a close, and we'll make it easy to spin up prod clusters using this code and eg. MemoryDB, Dragonfly, or what have you.
I've written quite a lot of CI for projects because it's something I believe in and am willing to roll up my sleeves to get done (as a concrete example). I believe strongly that being able to reference the canonical CI build helps contributors since they can see how it's built for different systems and also ensure they don't submit "works on my machine" patches
