Wrong Eureka instance port registration when server.port is random

Question

The port that the eureka-client provides to eureka-server is wrong when the server.port is defined with ${random.int}

• Example: When the server boots up the application port is set to 8050 but the Eureka instance have port 8064

• I configured the port to be random:

  server.port=${random.int(8500,8599)}
  

• I am expecting the server.port to be equal to the port on the eureka instance.

• Here's a diagram that represents briefly what I am trying to achieve Diagram

Answer 1

To ensure that the Eureka instance port matches the randomly assigned server.port, you can explicitly configure the Eureka instance's port in your application's configuration. Here's how you can do it:

Add the following property to your application.properties :

eureka.instance.nonSecurePort=${server.port}

By setting eureka.instance.nonSecurePort to ${server.port}, you explicitly instruct the Eureka client to use the same port as the one assigned to server.port for registration with the Eureka server.
