1. create and push docker image

   cd hellonode
   docker image build -t hfrtc/hellonode:1.0 .
   docker login
   docker image push hfrtc/hellonode:1.0

2. create pod

kubectl apply -f hellonode_pod.yaml
kubectl get pods

> NAME         READY   STATUS    RESTARTS   AGE
> hello-node   1/1     Running   0          5m5s

kubectl describe pod hello-node

3. create service

# create local service for hello-node pod
kubectl apply -f hellonode_svc.yaml
kubectl get svc

4. cleanup

kubectl delete pod hello-node
kubectl delete svc hello-svc

5. create deployment

$ kubectl apply -f hellonode-deploy.yaml
$ kubectl get deployments
----------------------------
NAME                READY   UP-TO-DATE   AVAILABLE   AGE
hello-node-deploy   3/3     3            3           6m30s

$ kubectl get pods

hello-node-deploy-86cc5b6bcc-5kdc6   1/1     Running   0          70s
hello-node-deploy-86cc5b6bcc-99hpf   1/1     Running   0          70s
hello-node-deploy-86cc5b6bcc-sntlc   1/1     Running   0          70s

$ kubectl delete pod hello-node-deploy-86cc5b6bcc-5kdc6

$ kubectl get pods

NAME                                 READY   STATUS    RESTARTS   AGE
hello-node-deploy-86cc5b6bcc-99hpf   1/1     Running   0          2m17s
hello-node-deploy-86cc5b6bcc-mx8f7   1/1     Running   0          54s
hello-node-deploy-86cc5b6bcc-sntlc   1/1     Running   0          2m17s
