The blog provides a comprehensive guide on implementing service discovery for a simple Java application interacting with a database within a Kubernetes environment. It specifically demonstrates setting up a one-node Kubernetes cluster using Minikube, defines application components with WildFly as the application server and Couchbase as the database, and details the deployment process, including the configuration of a Couchbase service and a WildFly replica set. The central focus is on utilizing the COUCHBASE_URI environment variable within the WildFly setup to enable dynamic service discovery, allowing seamless communication with the database. The blog also covers practical aspects like obtaining application logs, deploying the application via Kubernetes commands, and accessing the application through a Kubernetes proxy. The article concludes by highlighting the benefits of service discovery in Kubernetes and provides additional resources for further learning.
