I am 100% sure that the author of this post has never "built a kubernetes", holds at least one kubernetes cert, and maybe even works for a company that sells kubernetes products and services. Never been more certain of anything in my life. You could go point by point but its just so tiring arguing with these people. Like, the whole "who will maintain these scripts when you go on vacation" my brother in christ have you seen the kubernetes setups some of these people invent? They are not easier to be read into, this much is absolute. At least a shell script has a chance of encoding all of its behavior in the one file, versus putting a third of its behavior in helm variables, a third in poorly-named and documented YAML keys, and a third in some "manifest orchestrator reconciler service deployment system" that's six major versions behind an open source project that no one knows who maintains anymore because their critical developer was a Belarusian 10x'er who got mad about a code of conduct that asked him to stop mispronouning contributors.
