Spring Cloud Netflix和Docker Compose-无法向eureka注册服务 [英] Spring Cloud Netflix and Docker Compose - cannot register services with eureka

问题描述

我正在尝试使用docker-compose在本地(Ubuntu)运行2个简单服务:一个eureka服务器和一个配置服务器(这也是一个eureka客户端).两者都具有运行java -jar的简单dockerfile，公开其端口并可以正常工作.我还尝试添加eureka.client.service-url.defaultZone=http://company-service-discovery:8761/eureka来查看它是否可以注册，并且可以正常工作.

I'm trying to use docker-compose to run 2 simple services locally (Ubuntu): a eureka server, and config server (which is also a eureka client). Both of these have simple dockerfiles that run java -jar, expose their ports, and individually work fine. I also tried to add eureka.client.service-url.defaultZone=http://company-service-discovery:8761/eureka to see if it would register itself, and it worked.

我的配置服务器无法成功注册到eureka服务器，我已经对其进行了谷歌搜索，但没有发现有什么能帮助我解决这个问题.

My config server cannot successfully register to the eureka server, and I've googled it and nothing I've seen helped me solve this.

根据docker-compose文档，位于 https://docs.docker.com/compose/networking /:

According to docker-compose documentation at https://docs.docker.com/compose/networking/ :

默认情况下，Compose为您的应用设置一个网络.服务的每个容器都加入默认网络，并且都可以被该网络上的其他容器访问，并且可以在与容器名称相同的主机名下被它们发现.

By default Compose sets up a single network for your app. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.

在下面的示例中，web应该能够使用postgres://db:5432与数据库进行通信.

With the following example web should be able to use postgres://db:5432 to communicate with the database.

version: "3"
services:
  web:
    build: .
    ports:
      - "8000:8000"
  db:
    image: postgres
    ports:
      - "8001:5432"

我使用相同的方法来配置我的服务，但是我的配置服务器在尝试注册时被拒绝连接:

I have used the same method to configure my services, but my config server gets connection refused when trying to register:

version: '3.3'
services:
  company-service-discovery:
    build: company-service-discovery/
    ports:
      - "8761:8761"
  company-config-server:
    build: company-config-server/
    ports:
      - "8888:8888"
    links:
      - company-service-discovery

配置服务器bootstrap.yml

server:
  port: 8888

management:
  security:
    enabled: false

spring:
  application:
    name: company-config-server
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/shared
  profiles:
    include: native

eureka:
  client:
    service-url:
      defaultZone: http://company-service-discovery:8761/eureka

eureka服务器bootstrap.yml

spring:
  application:
    name: company-service-discovery

server:
  port: 8761

management:
  security:
    enabled: false

例外

问题

我的配置有问题吗?我该如何运作?

question

Is there anything wrong with my configuration ? How can I make it work ?

让我知道是否缺少任何信息，我会很乐意提供所有可能的信息.

Let me know if there's any info missing, I'll gladly give any info I can.

推荐答案

也将defaultZone配置添加到Eureka服务器的属性中(并在 配置服务器中将service-url更改为serviceUrl bootstrap.yml ).

Add the defaultZone configuration to the Eureka server's properties too (and change the service-url to serviceUrl in your config server bootstrap.yml).

spring:
  application:
    name: company-service-discovery

eureka:
  client:
    serviceUrl:
      defaultZone: http://company-service-discovery:8761/eureka

server:
  port: 8761

management:
  security:
    enabled: false
