+K8s Monitor CronJob 已在集群中运行，每 5 分钟扫描一次。Monitor 启动时会从 Log Center API（`GET /api/v1/projects`）动态拉取项目列表，自动生成 app label -> project_id 的映射。
 
-```python
-# k8s-monitor/monitor.py
-APP_TO_PROJECT = {
-    "rtc-backend": "rtc_backend",       # Pod 的 app label -> project_id
-    "rtc-backend-dev": "rtc_backend",
-    "rtc-web": "rtc_web",
-    "rtc-web-dev": "rtc_web",
-    "log-center-api": "log_center_api",
-    "log-center-web": "log_center_web",
-    # 新项目在此添加映射
-    "your-app": "your_project_id",
-}
-```
+**映射规则**：`project_id` 中的下划线替换为短横线作为 app label，同时生成 `-dev` 后缀变体。
+
+| project_id | 自动生成的 app label |
+|---|---|
+| `rtc_backend` | `rtc-backend`, `rtc-backend-dev` |
+| `rtc_web` | `rtc-web`, `rtc-web-dev` |
+| `log_center_api` | `log-center-api`, `log-center-api-dev` |
+
+**新项目接入 K8s 监控只需两步**：
+1. 在步骤 1 中完成项目注册（确保项目出现在 Log Center 项目列表中）
+2. K8s Deployment 的 `app` label 使用 `project_id` 的短横线形式
 
 确保你的 K8s Deployment 有 `app` label：
