#By default, your cluster will not schedule pods on the master for security reasons. If you want to be able to schedule pods on the master, e.g. for a single-machine Kubernetes cluster for development, run:
kubectl taint nodes --all node-role.kubernetes.io/master-

kubectl run demo-1 --image=gcr.io/google-samples/kubernetes-bootcamp:v1 --port=8080
kubectl expose deployment demo-1 --type=NodePort --name=demo-service

kubectl create -f deployment-echoserver.yaml
kubectl delete -f deployment-echoserver.yaml
