1 - 安裝 minikube
宿主機環境
- 操作系統： Windows 10
- 虛擬化： VirtualBox 6.1.14
Install kubectl
下載kubectl.exe,然後加入到系統環境變量PATH
Install minikube
下載 minikube-windows-amd64.exe 文件，並重命名爲minikube.exe,然後加入到系統環境變量PATH
- https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v1.13.0/minikube-windows-amd64.exe
從github下載
- kubectl： https://github.com/kubernetes/kubernetes/releases (在
CHANGELOG-*.*.md鏈接的“Client Binaries”區域) - minikube: https://github.com/kubernetes/minikube/releases
驗證
$ kubectl version

2 - 創建集羣
命令
minikube start --vm-driver=virtualbox --image-mirror-country=cn --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers --iso-url=https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/iso/minikube-v1.7.3.iso --registry-mirror=https://reg-mirror.qiniu.com
選項說明
--vm-driver: 虛擬機驅動，默認自動檢測，可選值 virtualbox, vmwarefusion, hyperv, vmware--image-mirror-country: 鏡像國家碼，默認使用全球代碼，中國大陸用戶可設置爲 cn--image-repository: 拉取集羣所需鏡像的倉庫--iso-url: 加速下載虛擬機安裝和啓動所需的ISO文件--registry-mirror: docker registry 的鏡像源，集羣安裝後拉取鏡像加速用，可以使用其它加速器地址--cpu: 虛擬機CPU數量--memory: 虛擬機內存大小--disk-size: 虛擬機磁盤大小- 更多選項
minikube start --help
