> An overview of Docker (the operating system containerization platform) from my perspective and experience.

Docker is a containerization platform. 

The way I like to describe it is that a user can create an isolated computer _inside_ of another computer that just has the things they've defined should be on it.

Docker knows what a user defined by the user giving it a `Dockerfile` when running the command. This file is how the user describes how the "computer" should look. A user could tell Docker to use a specific operating system, have specific executables and have certain environment variables.
