# 安装指定版本，例如：v0.22.3
$ curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.22.3/minikube-darwin-amd64
2、赋二进制文件执行权限
$ chmod +x minikube
3、将二进制文件移到 PATH 中 
$ sudo mv minikube /usr/local/bin/

1、安装最新版
curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/darwin/amd64/kubectl
2、赋二进制文件执行权限
chmod +x ./kubectl
3、将二进制文件移到 PATH 中
sudo mv ./kubectl /usr/local/bin/kubectl

1. Get your GitLab URL by running:
  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc -w gitlab-gitlab-ce'
  export SERVICE_IP=$(kubectl get svc --namespace default gitlab-gitlab-ce -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
  echo http://$SERVICE_IP/
2. Login as the root user:
  Username: root
  Password: 123456hwy
3. Point a DNS entry at your install to ensure that your specified
   external URL is reachable:
   http://my.gitlab.com/
