Overview of this book

This fast-paced practical guide will get you up and running with Docker. Using Docker, you will be able to build, ship, and run many distributed applications in real time. You will start with quickly installing Docker and start working with images and containers. We will present different types of containers and their applications, and show you how to find and build images. You will learn how you can contribute to the image repository by publishing different images. This will familiarize you with the image building process and you will be able to successfully run your programs within containers. By finishing this book, you will be well equipped in deploying your applications using Docker and will have a clear understanding of concepts, techniques, and practical methods to get it running in production systems.

Chapter 1. Introduction to Docker

At the beginning, Docker was created as an internal tool by a Platform as a Service company called dotCloud. Later on, in March 2013, it was released as open source. Apart from the Docker Inc. team, which is the main sponsor, there are some other big names contributing to the tool—Red Hat, IBM, Microsoft, Google, and Cisco Systems, just to name a few. Software development today needs to be agile and react quickly to changes. We use methodologies such as Scrum, estimate our work in story points, and attend the daily stand-ups. But what about preparing our software for shipment and the deployment? Let's see how Docker fits into that scenario and can help us to be agile.

In this chapter, we will cover the following topics:

  • The basic idea behind Docker
  • A difference between virtualization and containerization
  • Benefits of using Docker
  • Components available to install

We will begin with the basic idea behind this wonderful tool.
