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.
Running Microk8s on Ubuntu
We install microk8s with a single and simple command.
sudo snap install microk8s --classicUsing info command we can get the avaliable commands and services.

MicroK8s is a small, fast, secure, single node Kubernetes that installs on just about any Linux
box. Use it for offline development, prototyping, testing, or use it on a VM as a small, cheap,
reliable k8s for CI/CD. It's also a great k8s for appliances - develop your IoT apps for k8s and
deploy them to MicroK8s on your boxes.
