Why is this so heavily downvoted? A clear, legit opinion to have.
In my experience it's even like this: I have never seen any working kubernetes app. But I deployed my own hello world docker swarm app in 2 days. (And that is a fact, not an opinion. The opinion part is up to you.)
Because it's not remotely true, and is very cynical and biased without any evidence. k8s success isn't because of some consultancy marketing, it's because a lot of people are using it very successfully in production, myself included.
