docker - zuul， Eureka 服务器， Eureka 服务器和docker

Question

我对Docker和微服务有疑问。因此，我创建了ZuulService，EurekaServer + EurekaService，它在没有docker的情况下也可以正常工作。
但是我正在尝试研究docker，我创建了dockerfile，使用Maven创建了jar，并创建并运行了docker-compose.yml。 (谢谢，Maven)
Eureka (Eureka)有效，但Zuul说拒绝连接:

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，将zuul属性更改为

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

并运行docker-compose.yml，等到eureka启动，然后重新启动zuul和其他服务。 Eureka (Eureka)注册了他们。
