写在前面
- 自己搭CICD平台玩，但是少一个k8s的web端工具，请教老师之后发了这个给我，K8s的面板工具还是蛮多的，自己研究下
- 博文主要是
kuboard的安装，前提需要一个已经运行起来K8s集群。 - 另，因为涉及多机器操作，为了方便我配了ansible，这个不是必须.

一、简单介绍
Kuboard，是一款免费的 Kubernetes 图形化管理工具，Kuboard 力图帮助用户快速在 Kubernetes 上落地微服务..
官网： http://press.demo.kuboard.cn/overview/share-coder.html
二、安装 kuboard
1.安装 metric-server
查看节点状态,我们使用docker的话可以通过docker stats.那使用k8s的话，我们可以通过metric server来查看
docker 方式

两种方式任选其一，我们这里已经下载了镜像，所以直接导入，使用ansible所以机器执行
