- 学习K8s，整理记忆
- 博文内容涉及
- K8s面板工具dashboard和Kuboard.
- dashboard以及Kuboard部署Demo
- 部分地方使用了Ansible，只用了shell，copy模块
- 部分内容参考 dashboard K8s官方文档：https://Kubernetes.io/zh/docs/tasks/access-application-cluster/web-ui-dashboard/kuboard官网： http://press.demo.kuboard.cn/overview/share-coder.html
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、环境准备
无论是dashboard还是Kuboard，为了在页面上显示系统资源的使用情况，需要部署K8s核心指标监控工具Metrics Server,所以我们先来安装metric-server

kubernetes-dashboard是 Kubernetes的Web UI网页管理工具，可提供部署应用、资源对象管理、容器日志查询、系统监控等常用的集群管理功能。为了在页面上显示系统资源的使用情况，需要部署K8s核心指标监控工具Metrics Server
Github主页： https://github.com/kubernetes/dashboard
安装步骤资源文件(需要科学上网)：https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.0/aio/deploy/recommended.yaml
这里如果可以科学上网的小伙伴可以用这个，如果不行的话，用我的那个，yaml文件太大了，我放到了文末。
环境准备，工作节点push相关的镜像,这里因为有些镜像push不下来，所以替换为可以访问的镜像仓库来处理。
