在安裝搭建k8s的時候，往往會遇到各種各樣的問題，而安裝k8s的web展示組件kubernetes-dashboard則是困難中的困難，本人在實際搭建中則被整整卡住了2天，Google和百度輪番搜索，各種技術博客和技術視頻反復研究才勉強搭建成功

在安裝好k8s集群之后，確保集群各個節點都處于ready狀態的時候，就可以安裝kubernetes-dashboard了
如果沒有安裝好k8s集群，可以參考之前的文章：centos7.2 安裝k8s v1.11.0

創建kubernetes-dashboard.yaml文件

執行命令創建儀表盤所需要的所有容器

kubectl -n kube-system create -f .

訪問主節點的30090端口即可看到dashboard頁面

這里只是實現了kubernetes-dashboard的基本展示頁面，后續還有一些插件可以安裝，未完待續...
