如何安装K8s面板工具:kuboard

wuchangjian2021-11-15 01:16:28编程学习

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.

很多时候我们放弃,以为不过是一段感情,到了最后,才知道,原来那是一生。——匪我思存《佳期如梦》


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

相关镜像下载

curl -Ls https://api.github.com/repos/kubernetes-sigs/metrics-server/tarball/v0.3.6 -o metrics-server-v0.3.6.tar.gz
docker pull mirrorgooglecontainers/metrics-server-amd64:v0.3.6

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
