@CebotariM The goal of this project is to demonstrate how different micro-services can communicate within a Kubernetes cluster via NATS message bus.
Your service shouldn't expose any ports, as it is not supposed to be accessible to the "outside world".
Instead, all the requests are being handled by the gateway service, which is the main and only public entry-point to our cluster.
The gateway, then, forwards all the requests to the microservices, and returns their responses.
