docker - 通过Docker运行时，Eureka ZUUL “Forwarding error”

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

Eureka :

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

Zuul:

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}

当我在做docker-compose时，它正在正确地旋转容器，没有错误。
但是，当我使用API网关调用REST端点时，出现错误:com.netflix.zuul.exception.ZuulException:转发错误

最佳答案

问题出在我的用户服务应用属性中:

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
