I wonder if the "It's simple, just use kops!" etc, have tried to deploy kubernetes to anything other than a cloud service provider. Setting up a production grade Kubernetes cluster integrated on-prem with in-house development and operations teams is no small feat for anything other than a toy deployment. Kubernetes has benefits for some use cases, but I think some of the HN crowd underestimate the rather large investment of time and energy it can take to get there.
