Mac系统上安装

依赖kubectl

heartide@mac> kubectl version
Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.5", GitCommit:"32ac1c9073b132b8ba18aa830f46b77dcceb0723", GitTreeState:"clean", BuildDate:"2018-06-22T05:40:13Z", GoVersion:"go1.9.7", Compiler:"gc", Platform:"darwin/amd64"}

Server Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.0", GitCommit:"fc32d2f3698e36b93322a3465f63a14e9f0eaead", GitTreeState:"clean", BuildDate:"2018-04-10T12:46:31Z", GoVersion:"go1.9.4", Compiler:"gc", Platform:"linux/amd64"}

安装minikube

# 下载
brew cask install minikube

# 查看版本
heartide@mac> minikube version
minikube version: v0.28.0

装完0.28.0之后，执行后续的minikube start总是失败，详见：https://coding.imooc.com/lear...

因此

minikube stop
minikube delete
brew cask uninstall --force minikube
brew cask edit minikube
#See below for file 使用下面的配置覆盖该文件
brew cask install minikube

配置

cask 'minikube' do
  version '0.25.2'
