Building Services in Docker
Services are the most basic and straightforward way to run containers using a Docker swarm. They allow you to execute multiple replica containers across all nodes in the Swarm cluster. In this lab, you will have the opportunity to work with Docker services. You will practice scaling services by changing the number of replicas for an existing service. You will also have the opportunity to create a new service and run it in the cluster.
