## 查看

kubectl get pods
kubectl get pods -o wide

kubectl get services
kubectl get deployments
kubectl get nodes
kubectl get events

kubectl describe pods ${POD_NAME}


# ReplicaSet created by the Deployment
kubectl get rs

## 配置
kubectl config view
kubectl config use-context minikube

## 创建

kubectl create deployment --help

kubectl create deployment kubenetes-bootcmp --image=gcr.io/googles-sample/kubernetes-bootcmp:v1
kubectl create deployment --image=registry.cn-beijing.aliyuncs.com/guolb57/node-demo
kubectl delete deployment kubenetes-bootcmp

kubectl describe deployments/kubernetes-bootcamp

# scale
kubectl scale deployments/kubernetes-bootcamp --replicas=4
# scale down
kubectl scale deployments/kubernetes-bootcamp --replicas=2

## 显示k8sAPI
kubectl proxy

curl http://localhost:8001/version
curl http://localhost:8001

# 通过proxy和app通信
export POD_NAME=$(kubectl get pods -o go-template --template '{{range .items }} {{.metadata.name}} {{"\n"}} {{end}}')
curl http://localhost:8001/api/v1/namespaces/default/pods/demo-8569b86bfd-ptjqj/proxy/home/

# expose app to public

kubectl expose deployment/demo --type="NodePort" --port 8080

# 获取Nodeport port
export NODE_PORT=$(kubectl get services/kubernetes-bootcamp -o go-template='{{(index .spec.ports 0).nodePort}}')
curl $(minikube ip):$NODE_PORT
