We will use SPRING INITIALIZR (http://start.spring.io) to set up a new project for the Zuul API gateway. The following screenshot shows the GroupId, ArtifactId, and Dependencies to be selected:

The next step is to enable the Zuul proxy on the Spring Boot application. This is done by adding the @EnableZuulProxy annotation on the ZuulApiGatewayServerApplication class. The following snippet shows the details:

    @EnableZuulProxy
    @EnableDiscoveryClient
    @SpringBootApplication
    public class ZuulApiGatewayServerApplication {

We will run the Zuul proxy on port 8765. The following snippet shows the configuration that's needed in application.properties:

    spring.application.name=zuul-api-gateway
    server.port=8765
    eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka

We are configuring the port for the Zuul proxy and connecting it to the Eureka name server as well.
