1. Zero-ops Single node Kubernetes on any Linux box! Milindu Kumarage Senior Software Engineer Microk8s

2. The problem Why???!

6. Stopping and starting MicroK8s $ microk8s.stop $ microk8s.start

7. Using MicroK8s $ microk8s.kubectl get nodes

8. Using MicroK8s $ microk8s.kubectl get nodes Waiit?! What? `microk8s.kubectl` ??!1

9. Alias to Kubectl $ snap alias microk8s.kubectl kubectl $ kubectl # Now this is microk8s.kubectl $ snap unalias kubectl $ microk8s.kubectl config view --raw > ~/.kube/config

10. Switching Kubernetes versions! $ snap install microk8s --classic --channel=1.13/beta $ snap refresh --channel=1.12/stable microk8s ` $ snap install microk8s` will automatically upgrade
