I am trying to use docker-compose to run 2 simple services locally (Ubuntu): eureka server and config server (which is also eureka client). Both of them have simple docker files that run java -jar

, expose their ports, and individually work fine. I also tried adding eureka.client.service-url.defaultZone=http://company-service-discovery:8761/eureka

to see if it would register and it worked.

My config server cannot successfully register with the eureka server and I googled it and nothing I saw helped me solve this problem.

As per the docker composing documentation https://docs.docker.com/compose/networking/ :

By default, Compose sets up one network for your application. Each container for a service joins the network by default and is accessible to and discoverable by other containers on that network by a hostname that is identical to the container name.

The following example web

should be able to use postgres://db:5432

to communicate with the database.

version: "3"
services:
  web:
    build: .
    ports:
      - "8000:8000"
  db:
    image: postgres
    ports:
      - "8001:5432"

      

        
        
        
      

    

I used the same method to configure my services, but my config server gets rejected when trying to register:

docker-compose.yml

version: '3.3'
services:
  company-service-discovery:
    build: company-service-discovery/
    ports:
      - "8761:8761"
  company-config-server:
    build: company-config-server/
    ports:
      - "8888:8888"
    links:
      - company-service-discovery

      

        
        
        
      

    

config server bootstrap.yml

server:
  port: 8888

management:
  security:
    enabled: false

spring:
  application:
    name: company-config-server
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/shared
  profiles:
    include: native

eureka:
  client:
    service-url:
      defaultZone: http://company-service-discovery:8761/eureka

      

        
        
        
      

    

eureka server bootstrap.yml

spring:
  application:
    name: company-service-discovery

server:
  port: 8761

management:
  security:
    enabled: false

      

        
        
        
      

    

An exception

Question

Is there something wrong with my configuration? How can I get it to work?

Let me know if any information is missing, I will happily provide any information I can.
