Hacker News loves to make snarky comments about everything to do with K8s and YAML all the time, and yet in my experience the amount of times an issue was caused by actual YAML can be counted on one hand.

Way more often it’s developers who can’t figure out that their http library only supports 2 concurrent connections, or emit garbage/malformed log lines and then bitch that they can’t see their app logs because we dropped them, or can’t be fucked to do “kubectl describe” in their own developer namespace that they have full permission for.

If you truly experience issues with just using YAML then you need to skill up probably.
