一 官網安裝
官網： https://minikube.sigs.k8s.io/
搜了下網上如何通過Mac 安裝看網上文章很多，但是受限於國內網絡環境，很多都不行，各種下載失敗。如果你有VPN，那麼官方的步驟就容易走通：
$ 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
注意點：
- xhyve 已經不支持了。提示：darwin 不支持驅動程序“xhyve”
- 舊文檔的
brew cask install minikube 不推薦了，報錯：Cask 'minikube' is unavailable: No Cask with this name exists. 去掉cask直接安裝。
brew 本質是也是一整拉取Git的方式，所以還是想用不適用proxy的情況下如何安裝k8s.
我們需要安裝三樣東西：Kubernetes 的命令行客戶端 kubctl、一個可以在本地跑起來的 Kubernetes 環境 Minikube、以及給 Minikube 使用的虛擬化引擎hyperkit.
二 安裝步驟：
安裝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/
這是阿里雲版本：
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/
輸出版本號：minikube version
minikube version: v1.6.2
commit: 54f28ac5d3a815d1196cd5d57d707439ee4bb392
安裝 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
安裝kubectl
brew install kubectl
brew install docker-machine-driver-hyperkit
輸出kubectl --help 信息就OK
三 啓動
這個也很關鍵，網上默認的啓動報錯：
Darwin 10.14.6 上的 minikube v1.6.2

這裏需要在阿里雲有賬戶，開通鏡像加速。
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
參數對應的含義：
--image-mirror-country cn將缺省利用 registry.cn-hangzhou.aliyuncs.com/google_containers 作爲安裝Kubernetes的容器鏡像倉庫，--iso-url=***利用阿里雲的鏡像地址下載相應的 .iso 文件- --registry-mirror= 就是你在阿里雲的鏡像加速地址，必須的，不然很慢。

--image-repository= 不選擇會提示VM is unable to access k8s.gcr.io, you may need to configure a proxy or set --image-repository

新手記錄下自己搭建過程，主要是
minikube star
這裏一開始沒用對參數，各種報錯，然後刪除 ~/.minikube 再加上參數重試。
最後，引用下阿里雲的圖：Minikube利用本地虛擬機環境部署Kubernetes，其基本架構如下圖所示。
好了，開始你的k8s之旅吧。
