在安装搭建k8s的时候，往往会遇到各种各样的问题，而安装k8s的web展示组件kubernetes-dashboard则是困难中的困难，本人在实际搭建中则被整整卡住了2天，Google和百度轮番搜索，各种技术博客和技术视频反复研究才勉强搭建成功

在安装好k8s集群之后，确保集群各个节点都处于ready状态的时候，就可以安装kubernetes-dashboard了
如果没有安装好k8s集群，可以参考之前的文章：centos7.2 安装k8s v1.11.0

创建kubernetes-dashboard.yaml文件

执行命令创建仪表盘所需要的所有容器

kubectl -n kube-system create -f .

访问主节点的30090端口即可看到dashboard页面

这里只是实现了kubernetes-dashboard的基本展示页面，后续还有一些插件可以安装，未完待续...
