通过Docker运行时出现“转发错误”

Question

我正在使用docker compose容器部署3个项目：Eureka、Zuul服务和应用程序。以下是这些项目的配置：

尤里卡：

eureka.client.registerWithEureka = false
eureka.client.fetchRegistry= false
eureka.client.serviceUrl.defaultZone= http://${EUREKA_HOST}:8070/eureka/
eureka.instance.hostname= ${EUREKA_HOST}

祖尔：

eureka:
  client:
    serviceUrl:
      defaultZone: http://${EUREKA_HOST}:8070/eureka/
  instance:
    hostname: ${EUREKA_HOST}

应用

eureka.client.registerWithEureka = true
eureka.client.fetchRegistry= true
eureka.client.serviceUrl.defaultZone= http://${EUREKA_HOST}:8070/eureka/
eureka.instance.hostname= ${EUREKA_HOST}

当我做docker组装时，它正确地旋转容器，没有错误。然而，当我使用API网关调用RESTendpoint时，我得到了一个错误：com。netflix。祖尔。例外ZuuleException:转发错误

问题出在我的用户服务应用程序属性中：

eureka.client.registerWithEureka = true
eureka.client.fetchRegistry= true
eureka.client.serviceUrl.defaultZone= http://${EUREKA_HOST}:8070/eureka/
eureka.instance.hostname= ${EUREKA_HOST}

理想情况下应该是：

eureka.client.registerWithEureka = true
eureka.client.fetchRegistry= true
eureka.client.serviceUrl.defaultZone= http://${EUREKA_HOST}:8070/eureka/
eureka.instance.hostname= user-service
