搜集了 kubernets部署Dashboard的必要服务！史上最全，一次成功

kubernetes集群部署，如果想更直观地管理和监控k8s集群状况，kubernets-dashboard是一个普遍的方式。dashboard提供了一个WEB界面，使我们可以在网页上查看kubernetes的集群状态以及对集群进行相关的操作，方便了我们管理k8s集群。

在部署Dashboard的时候，遇到了很多问题，如网络问题，rbac权限的问题，由于官网上下在的yaml文件并不全面，上网查资料，也是不全面的，辗转于多个博客，论坛，终于把Dashboard部署的配置项整理齐全，终于部署成功。本人安装过多次，没有问题！所谓取之于互联网，用之于互联网。现把文件发布！希望让广大程序员少踩坑！

这里就介绍一下dashboard的部署。

ps：关于Dashboard的涉及的理论知识，请各位自行到k8s官网查阅！下面是yaml代码
