Introduction

Docker is a tool for packaging and shipping apps. Based on the idea of a shipping container, it provides a standardized way for developers or system administrators to create lightweight images, or collections of images, for each element of an application, and then easily and quickly deploy the image. Since the image is standardized, it can be uniformly deployed on development or production, leading to a much simpler workflow, faster development time for the dev team, and lower management overhead for the ops team.

First, a quick overview of a few things Docker is:

An open source tool that places a layer on top of Linux containers (cgroups and namespaces) to make it simple to package and ship complex apps
A tool for creating a layered filesystem; each layer is versioned and can be shared across running instances, making for much more lightweight deployments
A company behind the project, as well as a site called the "Docker Hub" for sharing containers
