Spring Cloud Eureka using IP addresses for service registration

By default, Eureka uses hostname for service registration and display of service information, so how do we configure it if we use an IP address? The answer is eureka.instance.prefer-ip-address=true .

Purpose: We are configured eureka.instance.prefer-ip-address=true to ensure that Eureka Server hostname use IP addresses when registering with each other while using IP addresses as eureka.client.service-url.defaultZone configuration values.

Eureka Server Cluster Configuration:

Debug:TrueSpring:  Application:    Name:Eureka-serverLogging:  Level :    Com.netflix.eureka: ' off '    Com.netflix.discovery: ' off '---Spring:  Profiles:Manager1Server:  Port:8100Eureka:  instance:    prefer-ip-address:True#以IP地址注册到服务中心, registering each other with an IP address    #ip-address:192.168.1.1 #强制指定IP地址, the default is to get the IP address of the machine  Client:    Service-url:      Defaultzone:http://192.168.1.2:8100/eureka/,http://192.168.1.3:8100/eureka/---Spring:  Profiles:Manager2Server:  Port:8100Eureka:  instance:    prefer-ip-address:TrueClient:    Service-url:      Defaultzone:http://192.168.1.1:8100/eureka/,http://192.168.1.3:8100/eureka/---Spring:  Profiles:Manager3Server:  Port:8100Eureka:  instance:    prefer-ip-address:TrueClient:    Service-url:      Defaultzone:http://192.168.1.1:8100/eureka/,http://192.168.1.2:8100/eureka/

Eureka Client Configuration:

debug: truespring:  application:    name: eureka-clientserver:  port: 8110eureka:  instance:    prefer-ip-address:#以IP地址注册到服务中心    #instance-id: http://192.168.1.4:8110 #服务中心的信息显示（如果IP地址不显示的话，进行配置）  client:    service-url:      defaultZone: http://192.168.1.1:8100/eureka/,http://192.168.1.2:8100/eureka/,http://192.168.1.3:8100/eureka/

Implementation effect (for reference only, does not contain Eureka Server Mutual registration IP addresses):

It is important to note that the above tests are not tested and are theoretically feasible.
