Yeah I agree it can be quite daunting, I recommend starting out small and trying to understand and getting one piece working at a time.

That is the approach I've taken while migrating my workloads from manually deployed services on old PC hardware into a fully declarative Kubernetes setup on a more energy efficient mini PC. Sounds scary but it's been a lot of fun actually!

I tried writing down some help on getting started, as well as short explanations on most of the infrastructure here in my homelab git repo: https://github.com/FruitieX/homelab/blob/main/docs/configuration.md

Hopefully that's helpful if you decide to try setting up something similar! 😎
