But this also isn't true. Everything k8s has caveats. You can't deploy a Percona MySQL DB on ARM for instance. Various operators have various issues which require manual intervention. It's all pretty much a clusterfuck. Then debugging reasons why this service works locally with a systemd service but not on k8s is also time intensive and difficult. And the steadily changing features and frequent version bumps. It's a full time job. And many helm charts aren't that great to begin with.

And what when someone deployment hangs and can't be deleted but still allocates resources? This is a common issue.
