Wrong status and health check urls if random management port

[gigermocas]

If I configure a random management port (management.server.port=0) in the eureka client's spring boot application properties, eureka calculates the statusPageUrl and healthCheckUrl with the incorrect port, i.e. not the actual management port, but the one for the default server.

I think that this is an unintended consequence of the fix for #2732, as the management web server initialization event is being disregarded, which it shouldn't for determining these specific urls.

I'm using the latest spring boot (2.7.5) and spring cloud (2021.0.4)

To be honest, trying to support random ports at all is like a house of cards. Marking for votes.

Same bug, bug spreads to prometheus when configured with eureka

Facing the same issue. For local testing the setup i'm using is managment.server.port=0 and server.port=0. Spring boot admin can not access actuator/** resources because eureka uses wrong port (and with the wrong port a 404 "no static resource" is returned). Would be nice to have a solution for this
