What Eureka Client did before register server?

Question

When I study the Hello world case of spring cloud Eureka service-registration-and-discovery, the client can register the server without define defaultZone in client configuration file.

I guess client will search all the servers and ports it can access? is it correct? if not, how client can find the server and register?

Answer 1

By taking a look into the Eureka Repo they define a default value for the eureka.serviceUrl.default:

# Since shouldUseDns is false, we use the following properties to explicitly specify the route to the eureka servers
 eureka.serviceUrl.default=http://localhost:8080/eureka/v2/
