Kotlin EE: Boost your Productivity
summary
Builds two services in Kotlin + Java EE API, one returning time and one calling it, using JAX-RS + Jackson for REST/JSON, packages each as a small WAR into Docker images, and deploys them to a 3-node local cluster managed by Docker Swarm. Service discovery uses container DNS by service name, images keep application layer small for fast rebuilds, and the demo scales the hello service to three replicas so responses show different hostnames and times.
