一 官网安装

 官网： https://minikube.sigs.k8s.io/

搜了下网上如何通过Mac 安装看网上文章很多，但是受限于国内网络环境，很多都不行，各种下载失败。如果你有VPN，那么官方的步骤就容易走通：

$ brew install kubectl    
$ brew install minikube     
$ brew install docker-machine-driver-hyperkit
$ sudo chown root:wheel /usr/local/opt/docker-machine-driver-hyperkit/bin/docker-machine-driver-hyperkit
$ sudo chmod u+s /usr/local/opt/docker-machine-driver-hyperkit/bin/docker-machine-driver-hyperkit
$ minikube start --vm-driver hyperkit

注意点：

• xhyve 已经不支持了。提示：darwin 不支持驱动程序“xhyve”
• 旧文档的brew cask install minikube  不推荐了，

  报错：Cask 'minikube' is unavailable: No Cask with this name exists.   去掉cask直接安装。

brew 本质是也是一整拉取Git的方式，所以还是想用不适用proxy的情况下如何安装k8s.

我们需要安装三样东西：Kubernetes 的命令行客户端 kubctl、一个可以在本地跑起来的 Kubernetes 环境 Minikube、以及给 Minikube 使用的虚拟化引擎hyperkit.

二  安装步骤：

  

安装minikube

curl -Lo minikube https://github.com/kubernetes/minikube/releases/download/v1.6.2/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

这是阿里云版本：

curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v0.30.0/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

输出版本号：minikube version

minikube version: v1.6.2
commit: 54f28ac5d3a815d1196cd5d57d707439ee4bb392

安装 hyperkit

curl -LO https://storage.googleapis.com/minikube/releases/latest/docker-machine-driver-hyperkit \
&& chmod +x docker-machine-driver-hyperkit \
&& sudo mv docker-machine-driver-hyperkit /usr/local/bin/ \
&& sudo chown root:wheel /usr/local/bin/docker-machine-driver-hyperkit \
&& sudo chmod u+s /usr/local/bin/docker-machine-driver-hyperkit

 安装kubectl

brew install kubectl
brew install docker-machine-driver-hyperkit

输出kubectl --help 信息就OK

三 启动

   这个也很关键，网上默认的启动报错：

这里需要在阿里云有账户，开通镜像加速。

minikube start --image-mirror-country=cn   --iso-url=https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/iso/minikube-v1.6.2.iso  --registry-mirror=https://XXXX.mirror.aliyuncs.com  --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers

参数对应的含义：

• --image-mirror-country cn 将缺省利用 registry.cn-hangzhou.aliyuncs.com/google_containers 作为安装Kubernetes的容器镜像仓库，
• --iso-url=*** 利用阿里云的镜像地址下载相应的 .iso 文件
• --registry-mirror= 就是你在阿里云的镜像加速地址，必须的，不然很慢。

• --image-repository=  不选择会提示VM is unable to access k8s.gcr.io, you may need to configure a proxy or set --image-repository

新手记录下自己搭建过程，主要是

minikube star

这里一开始没用对参数，各种报错，然后删除 ~/.minikube 再加上参数重试。

最后，引用下阿里云的图：Minikube利用本地虚拟机环境部署Kubernetes，其基本架构如下图所示。

好了，开始你的k8s之旅吧。
