详解通过docker和docker-compose实现eureka高可用

server:
 port: 8900

spring:
 application:
  name: eureka-server
 profiles:
  active: dev

management:
 security:
  enabled: false
 health:
  rabbit:
   enabled: false

spring:
 profiles: dev

eureka:
 client:
  serviceUrl:
   defaultZone: http://localhost:${server.port}/eureka/
  register-with-eureka: false
  fetch-registry: false
 instance:
  hostname: localhost
  prefer-ip-address: true

---
spring:
 profiles: test_ha_1

eureka:
 client:
  serviceUrl:
   defaultZone: http://eurekaserver2:${server.port}/eureka/
 instance:
  hostname: eurekaserver1
#  prefer-ip-address: true 该配置为true表示注册到eureka上的是IP，如果这样的化，eureka服务器就不能通过服务器发现Replicas。
#               故如果想通过Docker实现eureka高可用，该配置最好使用默认值（false）
#               此处配置为true且实现高可用也不是没有办法，就是每个eureka服务需映射到Docker环境外，且知道ip。
