在Ubuntu上安装Minikube

为了方便开发者体验Kubernetes，社区提供了可以在本地部署的Minikube。由于在国内网络环境内，无法顺利的安装使用Minikube，我们可以从阿里云的镜像地址来获取所需Docker镜像和配置。

  • 安装VirtualBox

sudo apt-get install virtualbox

  • 安装 Minikube

curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v0.35.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
