kubectl expose deployment hello-world --type=NodePort --name=example-service
kubectl get services
minikube service hello-node

minikube stop
minikube delete

kubectl -s http://localhost:8080 run nginx --image=nginx  --replicas=3 --port=80
kubectl get rc
kubectl get services
kubectl get deployments
kubectl get pods

kubectl get services
kubectl describe svc nginx

minikube ip

minikube service nginx --url

Test Hello World

kubectl apply -f https://k8s.io/examples/service/access/hello-application.yaml
kubectl get deployments hello-world
kubectl describe deployments hello-world
kubectl get replicasets
kubectl describe replicasets
kubectl expose deployment hello-world --type=NodePort --name=example-service
kubectl get pods --selector="run=load-balancer-example" --output=wide

kubectl cluster-info
curl http://<public-node-ip>:<node-port>

Test Hello Apps

kubectl create deployment web --image=gcr.io/google-samples/hello-app:1.0
kubectl expose deployment web --type=NodePort --port=8080
kubectl get service web
minikube service web --url
curl <URL>

Create an Ingress Resource

kubectl apply -f https://k8s.io/examples/service/networking/example-ingress.yaml
kubectl get ingress
minikube ip

edit sudo vi /etc/hosts

curl http://hello-world.info

2nd Deployment

kubectl create deployment web2 --image=gcr.io/google-samples/hello-app:2.0

Etc
