Java 与docker和kubernetes一起部署的Spring boot微服务应用程序：服务不通信

我在让我的应用程序服务相互通信时遇到问题。我所拥有的是一个由身份验证服务、发现服务器、api网关、商户服务组成的应用程序。我使用eureka服务器和客户端依赖项进行服务发现。每个服务都使用docker进行集装箱化，我使用K8进行编排

当我向服务器发送请求时，我得到的响应如下：

根据docker网络模型，docker容器在一个隔离的网络名称空间中运行

根据kubernetes网络模型，服务间通信可以通过多种方式实现：

• 容器到容器网络
• 点对点网络
• Pod到服务网络

只有在容器到容器联网的情况下，才能使用localhost解析微服务/应用程序

假设在这种情况下，没有两个容器在同一个Pod中运行，这是Pod到Pod网络/Pod到服务网络

在这种情况下，通过将eureka服务器区域感知url设置为kubernetes服务

ex:http://eureka-server:8080

以下是供您参考的样本：

注意：这是实现它的方法之一，服务注册/服务发现是kubernetes的现成功能，因此，eureka服务器的使用是可选的，完全取决于技术堆栈和要求。

请共享eureka属性集和kubernetes资源文件，通过查看日志获得帮助

serviceUrl=http://localhost:8761/eureka/

这在docker/kubernetes中不起作用，因为容器的部署方式和其网络模型。请验证其他重复的堆栈帖子和
