+# Nginx 部署文件
+
+此目录包含用于在 k3s 集群中部署 nginx 的 YAML 文件。
+
+## 文件说明
+
+- `nginx-deployment.yaml`: 包含基本的 nginx 部署和服务定义
+- `nginx-deployment-with-ingress.yaml`: 包含带有 ingress 规则的完整 nginx 应用部署
+- `deploy-nginx.sh`: 用于自动部署 nginx 的脚本
+
+## 部署方法
+
+### 方法 1: 使用基本部署文件
+
+```bash
+kubectl apply -f nginx-deployment.yaml
+```
+
+### 方法 2: 使用带 Ingress 的部署文件
+
+```bash
+kubectl apply -f nginx-deployment-with-ingress.yaml
+```
+
+### 方法 3: 使用部署脚本
+
+```bash
+chmod +x deploy-nginx.sh
+./deploy-nginx.sh
+```
+
+## 访问 nginx 服务
+
+如果使用了 LoadBalancer 类型的服务，可以通过外部 IP 访问：
+
+```bash
+kubectl get svc nginx-service
+```
+
+如果使用了 Ingress，可以通过配置的主机名访问（例如 nginx.local）。
+
+## 查看部署状态
+
+```bash
+kubectl get pods,svc,ingress -l app=nginx
+```
+
+## 删除部署
+
+```bash
+kubectl delete -f nginx-deployment.yaml
+```
