spring-boot - 当在Dockers上部署时，Spring Cloud Config Server在URL -http://localhost:8888上提供了Connect Timeout Exception

Question

我试图将我的spring-boot微服务转移到docker。当在本地系统上的STS上实现时，我的微服务运行得非常好。但是，当我对它们进行dockerize时，会出现连接超时错误。
我在下面分享我的代码段:
Docker撰写:

version: '3.6'
services:
  db:
    image: 'mysql:8.0.18'
    container_name: mysqldb
    ports:

    networks:
      - truyum-nw
  cart-service:
    image: cart-service
    build: ./cart-service
    container_name: cart-service
    ports:
      - '34001:34001'
    depends_on:
      - eureka
      - config-server
      - zuul
      - db
      - menu-item-service
      - auth-service
    networks:

  movie-service:
    image: movie-service
    build: ./movie-service
    container_name: movie-service
    ports:
      - '35000:35000'
    depends_on:
      - eureka
      - config-server
      - db
      - zuul
      - auth-service
    networks:
      - movie-cruiser-nw
  favourite-service:
    image: favourite-service
    build: ./favorite-service
    container_name: favourite-service
    ports:
      - '35001:35001'
    depends_on:
      - eureka
      - config-server
      - db
      - zuul
      - auth-service
      - movie-service
    networks:
      - movie-cruiser-nw
networks:
  truyum-nw:
    name: truyum-nw
    driver: bridge
  movie-cruiser-nw:
    name: movie-cruiser-nw
    driver: bridge

的 application.properties spring-cloud-config-server :

spring.cloud.config.server.git.uri = https://github.com/satyamthedeveloper/Stage4_Week2_841418_SatyamKumar
server.port=8888

的 application.properties Eureka 发现服务器:

spring.application.name=discoveryservice
spring.cloud.config.uri = http://spring-cloud-config-server:8888

 

当我执行docker-compose up并检查http://localhost:8888/discoveryservice/default时，我得到的结果为

{
    "name": "discoveryservice",
    "profiles": [
        "default"
    ],
    "label": null,
    "version": "8450532e432fb103ef30d0002fa254b23d2158d6",
    "state": null,
    "propertySources": [
        {
            "name": "https://github.com/satyamthedeveloper/Stage4_Week2_841418_SatyamKumar/discoveryservice.properties",
            "source": {
                "server.port": "8761",
                "eureka.client.register-with-eureka": "false",
                "eureka.client.fetch-registry": "false",
                "info.app.name": "Spring Eureka Server Application"
            }
        },
        {
            "name": "https://github.com/satyamthedeveloper/Stage4_Week2_841418_SatyamKumar/application.yml",
            "source": {
                "eureka.client.service-url.defaultZone": "http://eureka-discovery:8761/eureka",
                "logging.level.org.springframework.web": "DEBUG",
                "management.endpoints.web.exposure.include": "*"
            }
        }
    ]
}

但是，我的Eureka discovery service从8080开始，因为我没有公开它，所以无法访问。我尝试了其中一些步骤，但无济于事。

尝试在我的云配置启动并准备就绪时停止并重新启动发现服务。

通过创建网络仍然没有用，没有docker-compose分别尝试了它。

我不确定为什么我的服务无法获取可以使用URL轻松获取的链接。

您在 Eureka (eureka)配置中必须为配置服务器引用的名称仅为config-server，因为这是您撰写yaml中的服务名称。
