Registering a product service

The product service boots up and listens on port 8081 for product service requests. We will now add the necessary instructions so that the service instance registers itself with the Eureka registry. Thanks to Spring Boot, we only have to do a few configurations and annotations:

1. Add the dependencyManagement section with dependency on spring-cloud-netflix and the dependency in the existing dependencies section to spring-cloud-starter-eureka to the product service POM as follows:

1. The product service keeps renewing its lease every specific interval. Reduce it to 5 seconds, by defining an entry explicitly in the application.yml as follows:

server: 
  port: 8081 
 
eureka: 
  instance: 
    leaseRenewalIntervalInSeconds: 5

1. Include the annotation @EnableDiscoveryClient in the startup application class of the product project, in other words, ProductSpringApp. The @EnableDiscoveryClient annotation activates the Netflix Eureka DiscoveryClient implementation as that is the one we have defined in the POM file. There are other implementations for other service registries, such as HashiCorp Consul or Apache Zookeeper:

1. Now, start the product service as before:

At the end of the initialization of the product service, you will see log statements that register the service with the Eureka server.

To check whether the product service has registered, refresh the Eureka server page that you just accessed:

Also keep a tab on the Eureka log. You will find the lease renewal log statements of the product service.
