Eureka ZUUL "Forwarding error" when run through Docker

I am using docker-compose containers for deploying 3 projects: Eureka, Zuul Service and application. Below are the configurations for these projects:

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}

Application

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

When i am doing a docker-compose up it is spinning up the containers properly with no errors. However when i call a REST endpoint using API gateway i am getting the error: com.netflix.zuul.exception.ZuulException: Forwarding error

Solution

  • the problem was in my user-service app properties:

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

    which should ideally have been:

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