Spring微服务eureka客户端未在eureka服务器上注册

Question

我对docker，Spring框架的一切都很陌生…它们成功地在localhost环境中运行，现在我想把它们推送到docker中，但是总是给我错误，我在那里卡住了大约一周。有人能帮我弄清楚吗！！！

现在我有 eureka 服务器和云配置服务器服务，这是我的代码：

尤里卡服务器应用程序.yml

server:
  port: 8761
spring:
  application:
    name: service-registration
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
management:
  security:
    enabled: false

和 Dockerfile：

FROM openjdk:11
COPY target/service-registration-0.0.1-SNAPSHOT.jar service-registration.jar
EXPOSE 8761
CMD ["java", "-jar", "service-registration.jar"]

现在我有云配置服务器应用程序.yml：在这个文件中，我试图在github上备份它。从一开始，我就尝试将主机名更改为本地主机或任何其他主机名，如服务注册、尤里卡服务器等......但不是工作，并且“服务网址”或“服务网址”....

server:
  port: 9291

spring:
  application:
    name: cloud-config-server
  profiles:
    active: production
#  cloud:
#    config:
#      server:
#        git:
#          uri: https://github.com/sshaunn/config-server
#          clone-on-start: true

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    serviceUrl:
      defaultZone: http://service-registration:8761/eureka/
  instance:
#    prefer-ip-address: true
#    ip-address: http://eureka-server:8761/eureka/å
    hostname: service-registration

Dockerfile:

FROM openjdk:11
COPY target/cloud-config-server-0.0.1-SNAPSHOT.jar cloud-config-server.jar
EXPOSE 9291
ENTRYPOINT ["java", "-jar", "cloud-config-server.jar"]

和 docker-compose.yml 文件：

version: '3.7'
services:
  service-registration:
    image: service-registration
    networks:
      - eureka-server
    ports:

    depends_on:
      - service-registration
    container_name: cloud-config-server
    hostname: service-registration
    environment:

Answer 1

您应该使用您的主机ip地址在您的本地机器上运行。对于docker，它不应该是< code>localhost

请尝试在您的< code > application . properties 文件中使用以下配置。

eureka.client.service-url.defaultZone=http://host.docker.internal:8761/eureka/

好吧，我不知道为什么，但我建立了一个docker-compose.yml文件，它是这样的:注意，我在docker-compose.yml文件中设置了关于“服务URL”default zone的环境。

  service-registration:
    container_name: service-registration
