docker - Docker-SpringConfig-连接被拒绝到ConfigServer

Question

我正在尝试使用DockerCompose使用远程存储库部署ConfigServrService和客户端。

docker-compose.yml类似于:

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

在他们部署的那一刻，客户端控制台显示:

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

(代替 http://config-server:8888)

然后，控制台显示:

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

该服务正在尝试连接到 http://localhost:8888/user-server-config/desa而不是 http://config-server:8888。

客户端的application.yml文件为:

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

我不知道为什么uri会在最后包含 / user-server-config / desa 包含 http://localhost:8888 。代替application.yml中指示的 http://server-config:8888

Answer 1

根据spencergibb的建议here并根据official documentation的建议，创建一个bootstrap.yml文件:

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

并从 application.yml中删除上述包含的属性。
