MacOS下用minikube安装
安装VirtualBox
https://www.virtualbox.org/wiki/Downloads
下载安装for mac的版本，如 “ VirtualBox 6.0.4 platform packages” 下 的 OSX hosts，然后安装下载的img文件。
之后在下载 VirtualBox 6.0.4 Oracle VM VirtualBox Extension Pack，双击安装。
安装kubectl
brew install kubernetes-cli
安装minikube
brew cask install minikube
完成后测试一下：
$ kubectl version
Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.2", GitCommit:"cff46ab41ff0bb44d8584413b598ad8360ec1def", GitTreeState:"clean", BuildDate:"2019-01-13T23:15:13Z", GoVersion:"go1.11.4", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.2", GitCommit:"cff46ab41ff0bb44d8584413b598ad8360ec1def", GitTreeState:"clean", BuildDate:"2019-01-10T23:28:14Z", GoVersion:"go1.11.4", Compiler:"gc", Platform:"linux/amd64"}
启动minikube
如果是在可以翻墙的环境中，安装最新版本的kubernetes，可以简单执行命令：
minikube start
如果不支持全局翻墙，可以指定镜像地址，也可以指定要安装的kubernetes版本：
minikube start --memory=8192 --cpus=4 --disk-size=20g --registry-mirror=https://docker.mirrors.ustc.edu.cn --kubernetes-version=v1.12.5 --docker-env http_proxy=http://192.168.0.40:8123 --docker-env https_proxy=http://192.168.0.40:8123 --docker-env no_proxy=localhost,127.0.0.1,::1,192.168.0.0/24,192.168.99.0/24
minikube start --memory=8192 --cpus=4 --disk-size=20g --kubernetes-version=v1.12.5
实测下载还是出问题，怀疑是不是要在minikuber start 前面再加 http_proxy=http://192.168.0.40:8123 http_proxys=http://192.168.0.40:8123 稍后验证。
启动dashborad
标准方式，执行命令 minikube dashboard ，然后就会自动打开浏览器访问地址 http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login
备注：之前各个版本都正常，最近用v0.33.1的minikuber安装的kubernetes 1.13.2版本，遇到问题，报错如下：
$ kubectl version

$ minikube version
minikube version: v0.33.1
$ minikube dashboard

http://127.0.0.1:51695/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/ is not responding properly: Temporary Error: unexpected response code: 503
Temporary Error: unexpected response code: 503
Temporary Error: unexpected response code: 503
Temporary Error: unexpected response code: 503
导致无法打开dashboard，只好用 kubeproxy 的方式：
$ kubectl proxy
Starting to serve on 127.0.0.1:8001
然后手动打开地址： http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login
参考：https://stackoverflow.com/questions/52916548/minikube-dashboard-returns-503-error-on-macos
然后又是遇到 dashboard 登录的问题。
