Minikube安装成功Kubernetes,一次过！

介绍

Minikube 是 K8S 官方为了开发者能在个人电脑上运行 K8S 而提供的一套工具。实现上是通过 Go 语言编写，通过调用虚拟化管理程序，创建出一个运行在虚拟机内的单节点集群。

注：从这里也可以看出，对于 K8S 集群的基本功能而言，节点数并没有什么限制。只有一个节点同样可以创建集群。

大家在实际开发和体验 Kubernetes时，可能会遇到网络访问的原因或者其他的坑导致很多朋友无法使用minikube进行实验。因此我通过撰写这篇博客，让大家少走一点弯路。阿里云提供了一个修改版的Minikube,可以从阿里云的镜像地址来获取Docker镜像和配置。

坑位盘点

1. unable to cache ISO: connection failed because connected host has failed to respond.

   终端报错信息:

   minikube start
   
   o   minikube v0.35.0 on windows (amd64)
   >   Creating virtualbox VM (CPUs=2, Memory=2048MB, Disk=20000MB) ...

   报错原因: 由于无法从外网下载Minikube ISO出现如上报错。

   解决办法: 修改镜像地址为国内资源，解决网络错误。

2. Minikube doesn't run on VirtualBox

   终端报错信息:

   minikube start
