 2 | 
 3 | Golang实现登入k8s中指定pod内容器的Webshell功能，基于GIN框架、k8s/client-go，预留组内鉴权中间件。
 4 | 
 5 | Golang implements the webshell function of logging in k8s to specify pod content device. Based on gin framework and k8s/client-go, the authentication Middleware in the group is reserved
 6 | 
 7 | ## 快速开始
 8 | 1. 将项目根目录下的YOUR_K8S.conf替换为你自己的KUBECONFIG，如果是yaml文件直接将内容复制进.conf内即可
 9 | 2. 修改init_client.go中的ioutil.ReadFile("./YOUR_K8S.conf")中的文件名称
10 | 3. 确保你的KUBECONFIG正确,能在终端中通过kubectl get pod 获取pod
11 | 
12 | ## 流程
13 | - web端GET请求，server端响应前端资源
14 | - webshell发起websocket请求，server端升级连接
15 | - K8s/client-go 建立与container的ssh长连接，通过 websocket 连接实现PtyHandle接口的读写方法。
16 | - 使用组内中间件进行鉴权
17 | 
18 | 具体流程如下图所示:
19 | 
20 | ![image](https://github.com/GanonYou/k8s-webshell-gin/blob/master/k8s-webshell%20.jpg)
21 | 
22 | ## Quick Start
23 | 1. Replace YOUR_K8S.conf with your own kubeconfig. If it is a yaml file, copy the contents into .conf file directly
24 | 2. Modify init_client.go with correct .conf name
25 | 3. Make sure your kubeconfig can work and you can get the pod through 'kubectl get pod' in the terminal
26 | 
27 | ## Process
28 | - Web side get request, server side response front-end resources
29 | - Webshell initiates a websocket request and the server upgrades the connection
30 | - K8s/client-go establishes SSH long connection with container, and realizes reading and writing method of PtyHandle interface through websocket connection.
31 | - Use the middleware in the group for authentication
32 | 
33 | The specific process is shown in the following figure:
