如何在Spring Cloud中从客户端配置多个Eureka服务器

Question

从spring文档中，我看到我们可以一起拥有对等eureka服务器，因此对于Application.yml中的Eureka1，我可以拥有：

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

在Eureka服务器2中，我可以：

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

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}

Answer 1

在eureka.client.serviceurl.defaultzone中使用逗号分隔的对等项列表。

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