Microk8s
Zero Ops needed with a single k8s cluster done right. That's the marketing of microk8s. In practices, the product works very well but I found a bit slow(start and stop). However installing istio, is 1 command line away from happiness. Microk8s supports several versions of Kubernetes from 1.10+ to 1.13+ right now(20/04/2019) - k8s is 1.14+. If you are a hardcore Linux user you must try mcirok8s.
