<!-- Please use this template while reporting a bug and provide as much info as possible. Not doing so may result in your bug not being addressed in a timely manner. Thanks! --> **What happened**: 在 [dubbo-go xds 文档中](https://dubbogo.github.io/zh-cn/docs/user/tasks/mesh/app.html) 有说明：”对于一个只有客户端的应用，可以不创建sevice，可以由开发者在模板中修改，本教程中我们默认创建。“， 但是在最新版本的 `dubbo-go` 项目中情况与该文档描述不一致。 启动一个只有 consumer 的应用，会报 "panic: Discovery local Pod's host from xds, failed please register service with endpoint to k8s" 的错误。 通过查阅源码，发现问题出现在初始化 xds registry 过程中，具体出问题的代码如下： 该处代码总是会等待通过 xDS 查询到 localIP，直到超时。 ``` go // file: remoting/xds/client.go:454 // 2. found local hostAddr // todo: When would eds level watch be canceled? cancel2 = w.xdsClient.WatchEndpoints(update.ClusterName, func(endpoint resource.EndpointsUpdate, err error) { if foundLocal { return } for _, v := range endpoint.Localities { for _, e := range v.Endpoints { logger.Infof("[XDS Wrapped Client] Sniffing Found eds endpoint = %+v", e) if xdsCommon.NewHostNameOrIPAddr(e.Address).HostnameOrIP == w.localIP { cluster := xdsCommon.NewCluster(update.ClusterName) w.hostAddr = cluster.Addr foundLocal = true close(foundLocalStopCh) } } } }) ``` **What you expected to happen**: **How to reproduce it (as minimally and precisely as possible)**: **Anything else we need to know?**: -- This is an automated message from the Apache Git Service.
