2+ 
3+ 本指南旨在帮助您在 Kubernetes 中部署基于 ` wcjiang/linux-command `  镜像的 ` linux-command `  应用。该应用提供了一套 ` Deployment ` ,并通过 ` Service `  对外暴露服务端口。
4+ 
5+ ## 前提条件  
6+ 
7+ -  已安装并配置好的 Kubernetes 集群
8+ -  安装并配置好的 ` kubectl ` ,并连接至你的 Kubernetes 集群
9+ 
10+ ## 安装步骤  
11+ 
12+ 我们将使用此存储库中的` kubectl ` 应用 YAML 文件,该文件将安装 ` linux-command `  应用。
13+ 
14+ ``` bash 
15+ $ kubectl apply -f https://raw.githubusercontent.com/jaywcjlove/linux-command/master/deploy/yamls/linux-command.yaml
16+ ``` 
17+ 
18+ 检查 ` Deployment `  状态:
19+ 
20+ ``` bash 
21+ $ kubectl get deployments -n linux-command
22+ NAME            READY   UP-TO-DATE   AVAILABLE   AGE
23+ linux-command   1/1     1            1           17m
24+ ``` 
25+ 
26+ 你可以查看 ` Pod `  的状态以确保其正常运行:
27+ 
28+ ``` bash 
29+ $ kubectl get pods -n linux-command
30+ NAME                            READY   STATUS    RESTARTS   AGE
31+ linux-command-fff454654-427zp   1/1     Running   0          12m
32+ ``` 
33+ 
34+ 验证 ` Service `  是否成功创建并获取暴露的端口:
35+ 
36+ ``` 
37+ $ kubectl get services -n linux-command 
38+ NAME                    TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE 
39+ linux-command-service   NodePort   10.96.2.225   <none>        9665:30204/TCP   18m 
40+ ``` 
41+ 
42+ ## 访问应用  
43+ 
44+ 通过获取 ` NodePort `  的端口来访问应用。以下是获取 ` NodePort `  服务信息的命令:
45+ 
46+ ``` 
47+ $ kubectl get svc linux-command-service -n linux-command 
48+ ``` 
49+ 
50+ 根据输出,使用 ` EXTERNAL-IP:PORT `  访问服务。例如:
51+ 
52+ ``` 
53+ http://<Node-IP>:<NodePort> 
54+ ``` 
55+ 
56+ ## 卸载应用  
57+ 
58+ 如果需要删除已部署的资源,可以按以下顺序操作:
59+ 
60+ ``` 
61+ kubectl delete -f linux-command.yaml 
62+ ``` 
63+ 
64+ 这将会清理所有创建的 Kubernetes 资源。
