如何在Spring Cloud中从客户端配置多个Eureka服务器

Question

从spring doc,我看到我们可以将peer eureka服务器放在一起,所以对于Eureka1,在application.yml中,我可以:

spring:
  profiles: peer1
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://peer2/eureka/

在Eureka Server 2中,我可以:

spring:
  profiles: peer2
eureka:
  instance:
    hostname: peer2
  client:
    serviceUrl:
      defaultZone: http://peer1/eureka/

现在这两个eureka服务器互相认识,这很好.但是,现在在配置客户端时,当他们再次注册Eureka时,该怎么做？

在我的客户端应用程序中,我有:

eureka:
      instance:
        hostname: ${host.instance.name:localhost}
        nonSecurePort: ${host.instance.port:8080}
        leaseRenewalIntervalInSeconds: 5 #default is 30, recommended to keep default
        metadataMap:
          instanceId: ${spring.application.name}:${spring.application.instance_id:${random.value}}
      client:
        serviceUrl:
          defaultZone: http://(eurekaServerHost):8761/eureka/

    server:
      port: ${host.instance.port:8080}

所以现在我的问题是我应该在客户端application.yml中使用peer1或peer2作为EurekaServerHost吗？

谢谢

使用逗号分隔的对等列表eureka.client.serviceUrl.defaultZone.

eureka.client.serviceUrl.defaultZone=http://<peer1host>:<peer1port>/eureka,http://<peer2host>:<peer2port>/eureka
