How can anyone tell if they know kubernetes?
Most people who complain about k8s being complicated, convinced themselves they know it in the first place, and thought it is somehow going to make their life easier down the road. But it is not a plug and play tool as they hoped and unlike most tools where you can learn as you go, with k8s it becomes troubleshooting as you go.
It is like when I tried to use git branches on my first git based plaintext writing project. I thought it is nice and all but when you throw merge conflicts and rebase and remote branches within the first 2 weeks, it shifted from doing the actual thing, to just troubleshooting git. With k8s that is exponentially complicated.
