Introduction

The Docker tool was introduced to make it easier for developers to create, deploy, and run applications using containers. Containers provision the developers with the packaging of their applications, together with all important components they require such as libraries and other dependencies, and shipping of them all out as a single package. This assures the developers that their applications can be run on any other machine.
