k8s安装过程问题

minikube start命令执行失败问题

mac os，在安装完virtualbox以后，启动minikube 的时候，报错的问题

执行以下命令时

minikube start --registry-mirror=https://registry.docker-cn.com

报出错误

	E0222 14:54:38.177121   79361 start.go:529] StartHost: create: creating: Error setting up host only network on machine start: The host-only adapter we just created is not visible. This is a well known VirtualBox bug. You might want to uninstall it and reinstall at least version 5.0.12 that is is supposed to fix this issue

这个问题的原因是安装了virtualbox以后，会在安全性与隐私的通用tab下面画红框的地方，有一个允许oracle安装的应用巴拉巴拉的一段描述（并不显眼），然后还带一个允许按钮，点击打开左下角的小锁头，然后点击允许按钮，然后再重启电脑。有别的文档说要把隐私里的VirtualBox勾上，但是只勾那个并重启后并不管用。

minikube 创建的virtualbox的登录的用户名和密码

使用用户：docker，密码：tcuser登录。比如：
ssh docker@192.168.99.100，然后输入密码
