alt Hacker NewsSomehow we were doing that with deployment scripts and VM management tooling before Kubernetes became a thing, and without having to deal with YAML spaghetti.

Yes but Kubernetes takes these battle-tested scripts, and allow everyone to use them with a few lines of YAML ;)
I understand the dislike of YAML but a Kubernetes deployment is ~50 lines, if I had to build my own scripts with a similar feature set I don't think I would be able to get it down much more than that.

Yes, and Kubernetes came around as another player in that ecosystem and became popular for a reason, largely so we didn't have to manage clusters with imperative non-idempotent scripts with no runtime introspection or self-healing. I've done light devops (lab scale, not enterprise) off and on since cfengine was a thing, and while I'm no fan of the explosion of YAML (there's a special place in hell for helm in particular for using text/template to generate yaml), I'll take the controller loop design any day over most of the alternatives. Just having a sane API alone is a godsend: you ever try scripting vSphere?
