我有一个问题，我使用jhipster生成了3种微服务:网关，uaa和赌博生产者。
当我使用docker-compose一起运行3个服务时，它运行良好，然后我停止了赌博生产者服务，并在localhost上为此服务运行./mvnw，当它们一起工作时不起作用。网关无法提供此服务
我尝试了一些情况:
routes:
gamblingproducer:
url: http://localhost:8081
要么
routes:
gamblingproducer:
path: services/gamblingproducer/**
serviceId: gamblingproducer
引发异常:

请帮我
谢谢
最佳答案
始终将Localhost解析为容器本身的127.0.0.1。将localhost更改为运行eureka的主机ip或容器/服务名称，但不要使用localhost。当容器中的应用程序在分开的远程主机上运行时，请考虑一下它们。除非要循环回到同一个容器(几乎永远不会发生)，否则切勿使用localhost。
更新:
就像我说的，基于注释部分，问题出在“本地主机”及其处理方式上。据我了解，情况看起来像这样:主机上的mvnw正在连接到docker中的eureka，并说:“嗨，我是mnvw，您可以在localhost:8081上与我联系”。但是，eureka在尝试进行验证时会调用localhost，而您的主机会获得eureka的localhost(即容器)。因此，解决您的问题的方法是让mnvw说出可以通过eureka容器(而不是localhost)找到的主机名(或ip)。在容器方面，使用localhost非常棘手，所以要注意!
关于docker - 容器中的jhipster网关无法强制运行在localhost中的微服务，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/59916104/
