Spring cloud - Server and client

Question

I'm config an application using spring cloud eureka. I start my discovery app in the 8761 port and reaching the console in "http://localhost:8761".

So, I start my client application and it's appear in the "Application" page of eureka console.

First question: My client is using "server.port=0" in properties config so the tomcat port is starting in random. How can I reaching my services in client? Example: I have a get request in "/api/stuff", is that possible to access this not using the random port? Suppose I don't know the port!

Second Question: I can start any clients I want, they will start, assuming a random port and register in the cloud server discovery, I can see the log:

"Registering application FLY-CLIENT with eureka with status UP"

But they don't appear in "Application" page of eureka console, why they don't appear?

Thanks!

If you are using Spring RestTemplate to request the services registered in Eureka you need to make it @LoadBalanced, something like this should do the try:

@LoadBalanced
@Bean
RestTemplate restTemplate() {
    return new RestTemplate();
}

// usage
restTemplate.getForObject("http://your-service-name/api/stuff", StuffResponse.class);

As for the 2nd question, I'm a little confused, as you mentioned earlier in the question that your application appears on Eureka's dashboard. Is this behavior only happening for the "fly-client"?
