title: Service to service connection using RabbitMQ in nestjs
body: <pre><code>What I am looking for: a way to connect service to service connection through RabbitmMQ, where I have implemented a microservice in both services which means no port is there.
  </code></pre>
  <p>Gateway to service connection I have done. but the service-to-service connection without a port is my challenge.</p>
  <pre><code>anyone has an idea or some reference on how to implement this.
