You don’t really need to know a specific language to self-host anything. But things like YAML, JSON, Docker, and some networking basic will go a long way.
If I could do anything different though, it would definitely be to write more documentation. Document the steps taking setting things up, log notes on when you have to fix something, archive webpages and videos that you used along the way. Currently doing that myself now after some time self-hosting.
