-## CI/CD

-各服务仓库的 Gitea Actions 负责 build + push 镜像，并通过 `kubectl set image` 更新 Deployment。`regcred` 由 workflow 自动 create/update，`lpt-secrets` 需手动创建一次后保持不变。
+## Traefik
+
+Traefik 以 Docker 容器运行在宿主机，通过 file provider 加载路由规则，转发到 K8s NodePort。
+
+### 更新路由
+
+```bash
+# 将最新配置复制到 Traefik 挂载目录
+sudo cp traefik/dynamic.yml /etc/traefik/dynamic/k8s-lpt.yml
+
+# Traefik 自动检测文件变更，无需重启
+# 或手动验证
+sudo docker exec traefik cat /etc/traefik/dynamic/k8s-lpt.yml
+```
+
+### 端口对照
+
+| 服务 | dev NodePort | prod NodePort |
+|------|-------------|---------------|
+| lpt-fe | 30080 | 30180 |
+| lpt-be (api) | 30082 | 30182 |
+| lpt-ai | ClusterIP | ClusterIP |
