zull、eureka服务器、eureka服务和docker

Question

我有一个关于docker和微服务的问题。所以，我创建了ZuulService，EurekaServer + EurekaService，它可以在没有docker的情况下工作。但我正在尝试学习docker，我创建了我的dockerfile，使用Maven创建了jar，并创建并运行了docker-compose.yml。(谢谢，Maven)

Eureka工作，但Zuul说连接被拒绝：

2020-08-01 14:39:12.463  INFO 1 --- [           main] com.netflix.discovery.DiscoveryClient    : Getting all instance registry info from the eureka server
2020-08-01 14:39:12.695 ERROR 1 --- [           main] c.n.d.s.t.d.RedirectingEurekaHttpClient  : Request execution error

com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused (Connection refused)

application.yml

zuul:
  prefix: /api
  routes:
    user:
      path: /cat/**
      serviceId: CAT

    country:
      path: /country/**
      serviceId: COUNTRY

    about:
      path: /about/**
      servcieId: ABOUT

application.properties

spring.application.name=ZuulService
server.port=8080

eureka.client.service-url.defaultZone=http://localhost:8761/eureka
eureka.instance.prefer-ip-address=true

Answer 1

因此，在zuul属性中更改为

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

并运行docker-compose.yml，等待eureka启动，然后重启zuul和其他服务。尤里卡注册了他们。
