Spring Cloud - Registry Service port customization - spring-cloud

Question

I'd like to customize the Eureka port with Spring Cloud.
With the default port below, the services registry sees itself right (within the provided GUI)
spring:
application:
name: services-registry
server:
port: 8761
eureka:
instance:
hostname: localhost
nonSecurePort: ${server.port}
client:
register-with-eureka: true
fetch-registry: false
service-url:
default-zone: http://${eureka.instance.hostname}:${server.port}/eureka/
But if I just change server.port to 8787, no service can register itself, not even the services registry itself.

Can someone explain this issue and save my day? Thanks!

Answer 1

Ok, got it... the label after service-url property (which can be aliased as serviceUrl in YML) is a HashMap KEY, not a property label. So it has to be kept as a Camel Case tag in any ways!
eureka.client.service-url.defaultZone=http://[myIP#]:8787/eureka
