参考：

http://batizhao.github.io/2018/01/18/Running-Kubernetes-Locally-via-Minikube/

https://www.kubernetes.org.cn/installkubectl

使用Kubernetes命令行工具kubectl在Kubernetes上部署和管理应用程序。使用kubectl，可以检查集群资源; 创建，删除和更新组件。

准备工作

说明：安装 xhyve 驱动程序。此处可以不用安装，因为事先快已安装visualBox。

Step1:安装 kubectl

$ curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/darwin/amd64/kubectl

$ chmod +x ./kubectl
$ sudo mv ./kubectl /usr/local/bin/kubectl

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.1", GitCommit:"3a1c9449a956b6026f075fa3134ff92f7d55f812", GitTreeState:"clean", BuildDate:"2018-01-04T11:52:23Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"darwin/amd64"}

Step2:安装 Minikube

$ curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.24.1/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

$ minikube version
