"prefer-ip-address" of Eureka client not work in docker container
I'm using the same version of spring-boot and have a similar problem
But I think you are confusing IP address with the instance ID.
See this link: https://github.com/spring-cloud/spring-cloud-netflix/issues/1646#issuecomment-275121055
When you hover the mouse over the link or click on it, does it show the right IP-Address?
Anyway, I have two applications, one using spring-boot 1.5 where this property works.
With the 2.0 version the application always use the machine IP, instead what I informed in the eureka.instance.ip-address.

spring: application: name: uaa-service cloud: inetutils: ignored-interfaces: - eth0 - eth1 - eth2 - eth3 - loTaken from this
