Introduction

This tutorial will show you how to install Docker in Windows 7 operating system. Docker, from Wikipedia, is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.

So why do you need docker?

It allows developers to create a portable application that could be run on every machine. Instead of delivering jar, war, ear or other type of artifacts, you delivers image and someone else who wants to deploy your application, basically he/she deploys image on his/her machine with Docker installed. With docker installed you don’t have dependency of setting up the environments.
