Is there some way to clean up my kube stuffs for Lab 4.2? When I run k8sMaster.sh, it keeps show the error on "kubeadm init", attached
I follow this:https://stackoverflow.com/questions/44698283/how-to-completely-uninstall-kubernetes
Please read the introduction to the labs. You will note the labs direct you to use different nodes for the first lab, Exercise 2.5, and a new two node cluster for Exercise 4 and beyond. The note after Exercise 3.6, step 6 _and _Exercise 4.1: Overview and Preliminaries speaks to this point. If you already have Kubernetes running you will get the error you are seeing when you try to run kubeadm init again.
