Install Minikube On Macbook

在MacBook Pro 上安装minikube

根据官方文档操作。

检查macos是否支持虚拟机技术。

若要检查您的 macOS 是否支持虚拟化技术，请运行下面的命令：
sysctl -a | grep -E --color 'machdep.cpu.features|VMX'
如果你在输出结果中看到了 VMX （应该会高亮显示）的字眼，说明您的电脑已启用 VT-x 特性。

安装kubectl。

通过curl命令安装kubectl 可执行文件

通过以下命令下载 kubectl 的最新版本：
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl
若需要下载特定版本的 kubectl，请将上述命令中的 $(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt) 部分替换成为需要下载的 kubectl 的具体版本即可。

例如，如果需要下载 v1.18.0 版本在 macOS 系统上,需要使用如下命令：
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.18.0/bin/darwin/amd64/kubectl
修改所下载的 kubectl 二进制文件为可执行模式。
chmod +x ./kubectl
将 kubectl 可执行文件放置到你的 PATH 目录下。
sudo mv ./kubectl /usr/local/bin/kubectl

安装hypervisor

可选的hypervisor有HyperKit、VirutalBox、VMware Fusion，因为对VirutalBox比较熟悉，就选择安装了VirtualBox。

macOS安装VirtualBox时，会因为权限问题安装失败，在系统偏好设置中修改配置，允许安装oracle公司的软件，重新安装就可以安装成功了。

安装Minikube

macOS安装Minikube最简单的方法是使用Homebrew：
brew install minikube

以下是安装过程，非常非常慢。

安装确认

要确认 hypervisor 和 Minikube 均已成功安装，可以运行以下命令来启动本地 Kubernetes 集群

说明：若要为 minikube start 设置 –vm-driver，在下面提到的地方，用小写字母输入你安装的 hypervisor 的名称。指定 VM 驱动程序列举了 --vm-driver 值的完整列表。

说明：由于国内无法直接连接 k8s.gcr.io，推荐使用阿里云镜像仓库，在 minikube start 中添加 –image-repository 参数。
minikube start --driver=virtualbox --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers

dreamPython@MacBook-Pro killedman.github.io % minikube start --driver=virtualbox --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers
