To demonstrate the concepts discussed in this article, we'll use a demo Node.js application that provides an endpoint for the retrieval of Covid-19 statistics. It uses the free API provided by disease.sh.
You can transfer Docker images from one machine to the other in a variety of ways. The most popular method involves using the docker push command to push the image to the official Docker registry and retrieving it through the docker pull command.
Unlike our demo application, a real-world product will likely be composed of several different services that depend on each other for the application as a whole to properly work. Deploying to production usually means starting all the component services in the right order to ensure a smooth operation. You also need a strategy for other tasks, such as restarting a service in case of failures, aggregating logs, and performing health checks. All these concerns — and more — can be handled through Docker Compose.
