本文详细介绍了在腾讯轻服务器上安装K3S系统的过程，包括获取token、配置防火墙、SSH连接，以及使用Kubernetes Dashboard部署服务和管理节点。重点展示了K3S的节点信息、Kubernetes控制面板操作和nerdctl的安装与路径调整问题。

1.腾讯轻服务器K3S系统安装

前端时间买了三年腾讯轻服务器，现在准备学习下K8S，但是服务器资源少，退而求其次的使用腾讯轻服务器默认的K3S系统。

1.获取按照提示，获取token ，

2.防火墙开启9090端口，输入url：http://公网IP:9090登录；

3.开启SSH远程连接:创建密钥，默认下载文件，windows本地重命名增加后缀.pub,CRT通过公钥进行SSH登录。

2.Kubernetes-dashboard

输入url：http://公网IP:9090，可以看到相关菜单

点击右上角“+”，可以创建yaml文件进行服务部署

3.后台查看K3S相关信息
