我已经在 GKE 中部署了 mongo db、Spring Boot BE、Angular 应用程序。我的 FE 服务是一个负载均衡器，它需要与我的 BE 连接才能获取数据，但我在浏览器中收到控制台错误：GET http://contactbe.default.svc.cluster.local/contacts http://contactbe.default.svc.cluster.local/contacts网络::ERR_NAME_NOT_RESOLVED。我的FE需要消耗/联系人端点来获取数据。我在 Angular 应用程序中使用 BE 服务 (contactbe.default.svc.cluster.local) 中的 DNS。这是我用来创建部署的 yml 文件：

我用谷歌搜索了很多，但仍然没有找到如何解决这个问题。如果有人能伸出援手，我将不胜感激。

检查您的负载均衡器是否开放端口 27017 作为向端口 27017 发送请求
否则你可以将服务节点端口更改为80，目标端口将相同
