minikube dashboard #access Kubernetes Dashboard within Minikube

#Use kubectl to interact with the local cluster
kubectl run               hello-minikube --image=k8s.gcr.io/echoserver:1.4 --port=8080
kubectl expose deployment hello-minikube --type=NodePort #Exposing a service as a NodePort

#minikube makes it easy to open this exposed endpoint in your browser
minikube service hello-minikube

#Start a second local cluster:
minikube start -p cluster2
