Publishing a microservice as a service

Now that our swarm is ready, we can use it to create services that we can use for scaling, but first, we will create a shared registry in our swarm. Then, we will build a microservice and publish it into a Docker. Finally, we will learn how to scale our microservice and how to control it.
