eureka客户端没有向eureka服务器注册。

Question

我对码头，春天的框架非常陌生.他们成功地在本地主机环境上运行，现在我想把他们推进码头，但总是给我错误的地方，我被困在它大约一个星期。有人能帮我弄清楚吗！

现在我有了eureka服务器和云配置服务器服务，下面是我的代码：

尤里卡-服务器application.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"]

现在我有了云配置服务器application.yml:在这个文件中，我尝试在github上备份它。从一开始，我就试图将主机名更改为localhost或任何其他主机名，如服务注册、eureka-server等.但不是工作，还有“服务-url”或“serviceUrl”.

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"]

以及docker-compose.yml文件：

version: '3.7'
services:
  service-registration:
    image: service-registration
    networks:
      - eureka-server
    ports:
      - "8761:8761"
    container_name: service-registration
    hostname: service-registration
  cloud-config-server:
    build: cloud-config-server
    networks:
      - eureka-server
    ports:
      - "9291:9291"
    depends_on:
      - service-registration
    container_name: cloud-config-server
    hostname: service-registration
    environment:
      EUREKA_CLIENT_SERVICEURL_DEFAULTZONE: http://service-registration:8761/eureka

networks:
  eureka-server:
    name: eureka-server
    driver: bridge
#  route:
#    image: route
#    ports:
#      - "9191:9191"
#    container_name: api-gateway

#    environment:
#      EUREKA_CLIENT_SERVICEURL_DEFAULTZONE: http://service-registration:8761/eureka

​

这里的错误日志：

好的，我不知道为什么，但是我像这样设置了一个docker-compose.yml文件，它起作用了:注意，我在docker-come.yml文件中设置了关于"service-url“defaultZone的环境。

version: '3.7'
services:
  service-registration:
    container_name: service-registration
    build:
      context: ./service-registration
      dockerfile: Dockerfile
    ports:
      - "8761:8761"
  cloud-config-server:
    container_name: cloud-config-server
    build:
      context: ./cloud-config-server
      dockerfile: Dockerfile
    environment:
      - eureka.client.service-url.defaultZone=http://service-registration:8761/eureka
    depends_on:
      - service-registration
    ports:
      - "9191:9191"
  route:
    container_name: route
    build:
      context: ./route
      dockerfile: Dockerfile
    environment:
      - eureka.client.service-url.defaultZone=http://service-registration:8761/eureka
    depends_on:
      - service-registration
      - employee
      - income
    ports:
      - "9291:9291"
  employee:
    container_name: employee
    build:
      context: ./employee
      dockerfile: Dockerfile
    environment:
      - eureka.client.service-url.defaultZone=http://service-registration:8761/eureka
    depends_on:
      - service-registration
    ports:
      - "9001:9001"
  income:
    container_name: income
    build:
      context: ./income
      dockerfile: Dockerfile
    environment:
      - eureka.client.service-url.defaultZone=http://service-registration:8761/eureka
    depends_on:
      - service-registration
    ports:
      - "9002:9002"

您应该使用您的主机ip地址在本地计算机中运行。对于码头来说，它不应该是localhost

在您的application.properties文件中尝试使用以下配置。

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