here bootstrap.yml:

    info:       description: fii user interface mock service      spring:       application:         name: fii-rest-mocker       cloud:         config:           failfast: true           discovery:             enabled: true             serviceid: config-server           username: user           password: password      logging:       level:         com.netflix.discovery: 'off'         org.springframework.cloud: 'debug'      eureka:       instance:         leaserenewalintervalinseconds: 10         metadatamap:           instanceid: ${spring.application.name}:${spring.application.instance_id:${random.value}}       client:         serviceurl:           defaultzone: ${vcap.services.${prefix:}eureka.credentials.uri:http://user:password@localhost:8761}/eureka/      server:       port: 0 

if remove server.port bootstrap.yml , place in fii-rest-mocker.yml inside configuration server, service starts on random port, registered on 8080 in eureka.

i running 1 eureka server , 1 config server. services running on same machine.

so, how 1 service boot , register in eureka on random port?

i'm using 1.0.0.release version of spring-cloud , 1.2.2.release of spring-boot.

random ports not compatible spring.cloud.config.discovery.enabled: true @ moment.
