I agree, this was daunting for me too.

I use werf.io now (an opensource project which I am not affiliated with, I am just a user). It deploys my resources and waits to validate whether the deploy succeeded. They call it "giterminism".

You can do this yourself with scripts for sure, but I have not needed to extend any of their built in functionality yet.

Highly recommended for anyone using k8s with CD.
