Many of the posts I read here are about Docker. Is anybody using Kubernetes to manage their self hosted stuff? For those who've tried it and went back to Docker, why?

I'm doing my 3rd rebuild of a K8s cluster after learning things that I've done wrong and wanted to start fresh, but when enhancing my Docker setup and deciding between K8s and Docker Swarm, I decided on K8s for the learning opportunities and how it could help me at work.

What's your story?
