I wanted the same thing with Kubernetes and ended up using FluxCD. Highly recommend it. It basically syncs a git repo to the cluster, so you just push to github or whatever, and it auto applies the changes you pushed. Also, llm models tend to be good at teaching this topic and even writing yaml files for it, so the initial learning curve was not bad actually.

Now I’m exploring doing this even better with this template: https://github.com/onedr0p/cluster-template
