$ curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.24.1/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

$ minikube version
minikube version: v0.24.1

启动集群

1
$ minikube start --vm-driver=xhyve --registry-mirror=https://registry.docker-cn.com

$ kubectl get node
NAME       STATUS    ROLES     AGE       VERSION
minikube   Ready     <none>    13d       v1.8.0

进入集群

1
$ minikube ssh

或者使用 Minikube Docker 守护进程：

1
$ eval $(minikube docker-env)

如果不使用 Minikube，可以通过运行 eval $(minikube docker-env -u) 来撤消此更改。

确保以下镜像已经预先下载（查源码），可以使用这个脚本。
