This document introduces Docker and how it can help solve issues with deploying applications across different environments by standardizing the development workflow. Docker allows developers to build an application inside a container using a Dockerfile, ship the container image to Docker Hub for others to use, and then run the container anywhere including local development machines, test environments, and production servers. The document outlines how to set up Docker and the basic commands to build, ship, and run containerized applications.
