Downloading Docker images
In this recipe, we will download a Docker image. In a production environment, while creating a Docker image for an application, we need to add code and the configurations of our application over the top of an existing Docker image (sometimes referred to as a base image), such as Ubuntu, CentOS, and so on. When we deploy a container to a critical environment, we want to minimize the risk of delays.

In this recipe, we will also learn how to create a Docker image using Dockerfile.
