This is why I primarily see Kubernetes as a set of low-level primitives for a PaaS to build upon.
We don't use Kubernetes at my shop, we've begun to use OpenShift though which layers PaaS tooling on top of it and the developers on my team love it. They create a deployment, point it at the git repository containing their code, set their configuration and the app is live - the underlying primitives are available if we need them still, but that's for me to worry about as the DevOps guy and not the developers.
