写在前面

K9s 是一个基于终端UI的 K8S 管理工具
博文内容为 k9s 在 windows、Linux 以及docker 安装Demo
简单的热键使用。
理解不足小伙伴帮忙指正

K9s 是一个基于终端的管理 Kubernetes 集群的工具，旨在简化 Kubernetes 集群管理。和 kubebox 有些类似， K9s 同样可以持续监控集群的变化，并且可以提供与集群资源交互的快捷命令。如果说管理集群受限，只有一个终端你可以使用，那么 k9s 是一个不错的选择.

K9s 有一些特殊功能，可以显示 Kubernetes 资源之间依赖关系的 xray、显示集群高级状态的 pulse，以及扫描和报告已部署资源和配置问题的popeye 。
