6. 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.”
