Container不会在eureka服务中注册

时间：2018-03-24 22:23:56

标签： java spring docker netflix-eureka

我正在使用Docker Toolbox及其附带的Oracle VM。

自动注册在docker之外正常工作。 当我将其作为container运行时，我可以使用192.168.99.100:8761浏览器中的192.168.99.100:8080和VM来查看它们。只是client注册的eureka-service无效。

我还尝试使用network关联它们，当我inspect network时，它向我显示两个容器都在network中。但是客户端仍然没有在eureka-service中注册自己。

EUREKA-SERVICE

application.yml: 

server:
  port: 8761

eureka:
  instance:
    prefer-ip-address: true
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://192.168.99.100:8761/

bootstrap.yml: 

spring:
  application:
    name: eureka-service

MICROSERVICE（客户）

application.properties 

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/shop
spring.datasource.username=shop
spring.datasource.password=shop
server.port=8080

application.yml 

server:
  port: 8080
eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://192.168.99.100:8761/
                     //IP of the VM:EUREKA PORT

docker-compose.yml 

spring:
    jpa:
        database: MYSQL
        hibernate:
            ddl-auto: validate

    datasource:
        url: jdbc:mysql://mysql:3306/shop
        username: shop
        password: shop
        driver-class-name: com.mysql.jdbc.Driver

将日志级别设置为info，并在启动应用程序时检查应用程序日志，注意这些日志：

检查注册状态是否为204。

如果没有找到，请检查网络问题，如果您发现以下情况，是否可以访问eureka：

要检查eureka是否可访问，如果您的eureka是在spring cloud中启动的，请执行curl http://192.168.99.100:8761/eureka/apps以查看是否可以获取服务器列表。
