# 02-03 Nginx + 工作节点 + IngressM3
> 场景nginx 随机一台工作节点(`nodeSelector: node-role.kubernetes.io/worker: ""`),跨节点 Ingress 暴露 `/demo-m3`。整合于 `02-05-nginx-验证矩阵-一键部署.md`。
## 前置条件
- 已完成 `01-02-k3s-工作节点.md`
- 工作节点有 `node-role.kubernetes.io/worker` 标签
- 工作节点网络连通8472/udp、firewalld 基线)
## 操作步骤
1. 部署 nginx DeploymentnodeSelector 工作节点标签,随机调度)+ Service
2. 创建 Middleware + Ingress`/demo-m3` -> nginx-m3:80
3. 等待资源就绪
示例 YAML 见 `ansible/files/02-05-nginx-matrix/03-worker-ingress.yaml`
## 部署命令
```bash
kubectl apply -f ansible/files/02-05-nginx-matrix/03-worker-ingress.yaml
```
## 验证命令
```bash
kubectl get pod,svc,ing -n default -o wide
curl -i --max-time 3 http://<入口节点IP>/demo-m3/
```
## 预期
- 返回 200页面包含 Welcome to nginx!
- Pod 落在任一工作节点(随机调度)
## 删除
```bash
kubectl delete -f ansible/files/02-05-nginx-matrix/03-worker-ingress.yaml
```
## 失败排查
- 检查 8472/udp、firewalld 转发flannel.1/cni0 trusted
- 参考 `06-01-k3s-networkpolicy-故障排查.md`
## 下一步
- 返回 `02-05-nginx-验证矩阵-一键部署.md``00-00-构建总览.md`
