Running Eureka on the server side

Running the Eureka Server within a Spring Boot application is not a difficult task. Let's take a look at how this can be done:

1. First, the right dependency has to be included to our project. Obviously, we will use a starter for that:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>

2. Eureka Server should also be enabled on the main application class:

@SpringBootApplication
@EnableEurekaServer
public class DiscoveryApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(DiscoveryApplication.class).web(true).run(args);
    }

}

3. It is interesting that together with the server starter, client's dependencies are also included. They can be useful for us, but only when launching Eureka in high availability mode with peer-to-peer communication between discovery instances. When running a standalone instance...
