What does Docker do?

■ “Docker allows you to package an application with all of its

dependencies into a standardized unit for software development.”

■ “Docker containers wrap up a piece of software in a complete filesystem

that contains everything it needs to run:

code, runtime, system tools, system libraries – anything you can install

on a server. This guarantees that it will always run the same,

regardless of the environment it is running in.”
