If you want to wipe out your local Minikube cluster and restart, it is very easy to do so. Issuing a command to delete and then start Minikube will wipe out the environment and reset it to a blank slate:
minikube delete
Deleting local Kubernetes cluster...
Machine deleted.
minikube start
Starting local Kubernetes v1.7.5 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
Kubectl is now configured to use the cluster.
