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我所渴求的，無非是將心中脫穎語出的本性付諸生活，為何竟如此艱難呢 ------赫尔曼·黑塞《德米安》
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。
