检查版本	minikube version
启动集群	minikube start
检查kubectl版本	kubectl version
检查集群信息	kubectl cluster-info
获取nodes	kubectl get nodes
部署应用(Deployment)
创建Deployment	kubectl create deployment kubernetes-bootcamp --image=gcr.io/google-samples/kubernetes-bootcamp:v1
获取Deployment	kubectl get delpoyments
获取代理	kubectl proxy  ● 直接接入Cluster内部，可以不用kubectl而直接通过curl发送api
探索应用程序
列出资源	kubectl get <resource-name>
显示有关资源的详细信息	kubectl describe <resource-name>
获取pods和其中容器的log	kubectl logs <pod-name>
在pod中的容器内运行	kubectl exec <pod-name> <command>

公开应用	kubectl expose
添加标签	kubectl label <resource-type> <resource-name> <label-name>
minikube ip	$(minikube ip)
应用的扩展
增加副本(replica)	kubectl scale <type> <resource-name> --replicas=<count>
