[I] [BUG] 快速入门(Docker)：real request与upstreamUrl的示例配置易使新手因网络上下文混淆而连接失败 [shenyu]</span></a></span> </h1> <p class="darkgray font13"> <span class="sender pipe"><a href="/search?l=notifications@shenyu.apache.org&q=from:%22via+GitHub%22" rel="nofollow"><span itemprop="author" itemscope itemtype="http://schema.org/Person"><span itemprop="name">via GitHub</span></span></a></span> <span class="date"><a href="/search?l=notifications@shenyu.apache.org&q=date:20250508" rel="nofollow">Thu, 08 May 2025 20:45:19 -0700</a></span> </p> </div> <div itemprop="articleBody" class="msgBody">  <pre> fantasy-lotus opened a new issue, #6020: URL: <a rel="nofollow" href="https://github.com/apache/shenyu/issues/6020">https://github.com/apache/shenyu/issues/6020</a></pre><pre> ### Is there an existing issue for this? - [x] I have searched the existing issues ### Current Behavior 在阅读了官方README的快速上手部署容器后，我在 macOS 宿主机上启动了一个监听 127.0.0.1:8080 的 HelloWorld 后端服务，并严格按照指南启动 shenyu-admin 和 shenyu-bootstrap 容器（均在 shenyu Docker 网络中）并配置了selectorHandler，当尝试通过网关（<a rel="nofollow" href="http://localhost:9195/helloworld）访问后端服务时，shenyu-bootstrap">http://localhost:9195/helloworld）访问后端服务时，shenyu-bootstrap</a> 容器日志显示它尝试连接自身内部的 127.0.0.1:8080，而不是宿主机上运行的后端服务。这直接导致了 Connection refused 错误❌ ### Expected Behavior 原因是我启动的后端HelloWorld服务在宿主机上，容器内部访问127.0.0.1无法映射到宿主机仔细阅读了文档后，可能的意思是 1. 后端服务被打包并运行在了 shenyu-bootstrap 容器的内部，并且监听了这个容器自己的 127.0.0.1 (localhost) 的 8080 端口（不太可能） 2. 在docker shenyu network中，用户需要自己部署一个后端服务，但文档本身并没有提供启动这个示例后端服务的步骤 🤯新手困惑的原因：在 Docker 环境下，shenyu-bootstrap 容器内的 127.0.0.1:8080 指向的是该容器自身对于Docker 网络上下文不太熟悉的用户（以前的我），可能期望快速上手提供一个无需修改就能直接工作的端到端示例，容易将 127.0.0.1:8080 理解为宿主机的 localhost 💡可能的解决方案： 1. 引导用户在宿主机上启动后端服务并监听localhost:8080, 同时把upstreamUrl改为host.docker.internal:8080 2. 提供在docker shenyu network中启动后端示例服务的步骤 ### Steps To Reproduce 按照快速上手(docker)部署shenyu并配置selectorHandler upstreamUrl为127.0.0.1:8080, 同时在宿主机启动后端服务 ### Environment ```markdown ShenYu version(s):docker latest 运行环境：macOS (Docker Desktop) ``` ### Debug logs [0a883217-38] formatError:Resolved [AnnotatedConnectException: finishConnect(..) failed: Connection refused: /127.0.0.1:8080] for HTTP GET /favicon.ico throwable: io.netty.channel.AbstractChannel$AnnotatedConnectException: finishConnect(..) failed: Connection refused: /127.0.0.1:8080 ### Anything else? _No response_ -- This is an automated message from the Apache Git Service.
