 **验证**：重启微服务后，Nacos 控制台应显示真实宿主机 IP（如 `192.168.1.101:9000`、`192.168.1.102:9000`）

+### Q13: Sentinel 控制台显示容器内部 IP 或实例失联
+
+**问题描述**：
+- Sentinel 控制台显示机器列表 IP 为 `172.18.0.x` 等 Docker 内部 IP
+- 部分实例显示"失联"状态，健康实例数不正确
+- 跨节点无法进行限流降级
+
+**原因**：与 Nacos 问题类似，Sentinel 客户端使用容器内部 IP 注册到 Dashboard，导致跨节点无法通信。
+
+**解决方案**：在 docker-compose 中添加 `SPRING_CLOUD_SENTINEL_CLIENT_IP` 环境变量：
+
+```yaml
+# Node-01 (192.168.1.101)
+video-gateway:
+  environment:
+    - SPRING_CLOUD_SENTINEL_CLIENT_IP=${HOST_IP:-192.168.1.101}

+```
+
+**验证**：重启微服务后，Sentinel 控制台应显示真实宿主机 IP，且所有实例状态为"健康"
