+# 快速入门指南
+
+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。
+
+## 前提条件
+
+- 已安装并配置好的 Kubernetes 集群
+- 安装并配置好的 `kubectl`，并连接至你的 Kubernetes 集群
+
+## 安装步骤
+
+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。
+
+```bash
+$ kubectl apply -f https://raw.githubusercontent.com/jaywcjlove/linux-command/master/deploy/yamls/linux-command.yaml
+```
+
+检查 `Deployment` 状态：
+
+```bash
+$ kubectl get deployments -n linux-command
+NAME            READY   UP-TO-DATE   AVAILABLE   AGE
+linux-command   1/1     1            1           17m
+```
+
+你可以查看 `Pod` 的状态以确保其正常运行：
+
+```bash
+$ kubectl get pods -n linux-command
+NAME                            READY   STATUS    RESTARTS   AGE
+linux-command-fff454654-427zp   1/1     Running   0          12m
+```
+
+验证 `Service` 是否成功创建并获取暴露的端口：
+
+```
+$ kubectl get services -n linux-command
+NAME                    TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE
+linux-command-service   NodePort   10.96.2.225   <none>        9665:30204/TCP   18m
+```
+
+## 访问应用
+
+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：
+
+```
+$ kubectl get svc linux-command-service -n linux-command
+```
+
+根据输出，使用 `EXTERNAL-IP:PORT` 访问服务。例如：
+
+```
+http://<Node-IP>:<NodePort>
+```
+
+## 卸载应用
+
+如果需要删除已部署的资源，可以按以下顺序操作：
+
+```
+kubectl delete -f linux-command.yaml
+```
+
+这将会清理所有创建的 Kubernetes 资源。
