docker for mac 自从在1.7.12 CE Edge 发行版本后，集成了kubernetes.

你可以在这里下载 （注意，目前只能下载Edge发行版本，才支持kubernetes）：

https://store.docker.com/editions/community/docker-ce-desktop-mac

详细使用文档：

https://docs.docker.com/docker-for-mac/

安装后，先要打开kubernetes选项：

之后，点击 “apply” 就开始安装kubernetes.等右下角“kubernetes staring” 变绿色，就表示安装完成。

客户端工具kubectl 也会自动安装，如果你曾经安装过kubectl并连接其他kubernetes,你需要切换一次context(切换到docker-for-desktop):

mac-temp:~ test$ kubectl config get-contexts
CURRENT   NAME                 CLUSTER                      AUTHINFO             NAMESPACE
          docker-for-desktop   docker-for-desktop-cluster   docker-for-desktop   
*         kubernetes           kubernetes                   admin                


be sure to change context so that kubectl is pointing to docker-for-desktop:
mac-temp:~ test$ kubectl config use-context docker-for-desktop
Switched to context "docker-for-desktop".

检查是否安装的版本：

mac-temp:echo test$ kubectl version
Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.2", GitCommit:"5fa2db2bd46ac79e5e00a4e6ed24191080aa463b", GitTreeState:"clean", BuildDate:"2018-01-18T10:09:24Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.2", GitCommit:"5fa2db2bd46ac79e5e00a4e6ed24191080aa463b", GitTreeState:"clean", BuildDate:"2018-01-18T09:42:01Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"}

查看节点：

mac-temp:echo test$ kubectl get nodes
NAME                 STATUS    ROLES     AGE       VERSION
docker-for-desktop   Ready     master    47m       v1.9.2

 查看集群信息：

mac-temp:echo test$ kubectl cluster-info
Kubernetes master is running at https://localhost:6443
KubeDNS is running at https://localhost:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

参考所有组件：

当你不使用kubernetes，可以暂时禁用它，免得占用系统资源：
