Are there good guides for hosting Mastodon from 0 to 500-1,000 users (and potentially beyond)? I'm trying to avoid making stupid mistakes, like using a provider's "1-click installer" and then discovering that I'd hit a capacity wall quickly and have to start over, or choosing an architecture that would quickly become prohibitively expensive. Basically, I'm hoping for a map with recommendations and "here there be dragons" information.

Something like masto.host could be interesting, but their prices seem a bit high and all of their plans are currently unavailable anyway. I've read https://docs.joinmastodon.org/user/run-your-own/, but it's missing even basic sizing guidance. I found what appears to be an official Docker image at https://hub.docker.com/r/tootsuite/mastodon, but no instructions on using it.

Any feedback is welcome, thank you!
