1.Create a cluster

minikube version
minikube start
kubectl version
kubectl cluster-info
kubectl get nodes

2.Deploy an App

kubectl get nodes --help
kubectl run DEPLOYMENT_NAME --image=mysql:5.7 --port=8080
kubectl get deployments
kubectl get pods

3.Explore your App

* kubectl get - list resources
* kubectl describe - show detailed information about a resource
* kubectl logs - print the logs from a container in a pod
* kubectl exec - execute a command on a container in a pod
kubectl proxy

4.Expose your App publicly

kubectl get services
kubectl expose deployment/kubernetes-bootcamp --type="NodePort" --port 8080
kubectl describe services/kubernetes-bootcamp
kubectl get pods -l run=kubernetes-bootcamp
kubectl get services -l run=kubernetes-bootcamp
export POD_NAME=$(kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}')
export NODE_PORT=$(kubectl get services/kubernetes-bootcamp -o go-template='{{(index .spec.ports 0).nodePort}}')
kubectl label pod $POD_NAME app=v1
kubectl describe pods $POD_NAME
kubectl get pods -l app=v1
kubectl delete service -l run=kubernetes-bootcamp
kubectl exec -ti $POD_NAME curl localhost:8080

5.Scale your App

kubectl scale deployments/kubernetes-bootcamp --replicas=4
kubectl get pods -o wide
kubectl describe deployments/kubernetes-bootcamp
kubectl describe services/kubernetes-bootcamp

6.Update your App

kubectl set image deployments/kubernetes-bootcamp kubernetes-bootcamp=jocatalin/kubernetes-bootcamp:v2
kubectl rollout status deployments/kubernetes-bootcamp //验证是否更新完成
kubectl rollout undo deployments/kubernetes-bootcamp //取消更新/回退
