Docker - SpringConfig - Connection refused to ConfigServer

问题

I'm trying to deploy a ConfigServrService and a Client with a remote repository using DockerCompose.

The docker-compose.yml is like:

version: '2'

services:

  rabbitmq:
    image: rabbitmq
    ports:
      - "5672:5672"

  config-server:
    image: config-server
    environment:
      - "SPRING_PROFILES_ACTIVE=desa"
    ports:
      - "8888:8888"
    links:
      - rabbitmq
    depends_on:
      - rabbitmq

  user-service-config:
    image: user-service-config
    environment:
      - "SPRING_PROFILES_ACTIVE=desa"
    ports:
      - "8090:8090"
    links:
      - config-server
      - rabbitmq
    depends_on:
      - rabbitmq
      - config-server

At the moment that they are deploying, the client console shows:

c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at: http://localhost:8888

(Instead of http://config-server:8888)

And after that, the console shows:

Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/user-server-config/desa": Connection refused; nested exception is java.net.ConnectException: Connection refused

The service is trying to connet to http://localhost:8888/user-server-config/desa instead of http://config-server:8888.

The application.yml file of the client is:

server:
  port: 8090
spring:
  rabbitmq:
    host: 172.17.0.1
    port: 5672
    username: guest
    password: guest

  application:
    name: user-server-config
  cloud:
    enabled: true
    config:
      uri: http://config-server:8888
      failFast: true
      retry:
        maxAttempts: 20

management:
  security:
    enabled: false

I do not know why the uri contains http://localhost:8888 with /user-server-config/desa at the end. Instead of http://server-config:8888 as is indicated in the application.yml

回答1:

As suggested by spencergibb here, and as the official documentation suggests, create a bootstrap.yml file:

spring:
  cloud:
    enabled: true
    config:
      uri: http://config-server:8888
      failFast: true
      retry:
        maxAttempts: 20

and remove the above included properties from application.yml.
