Docker

This tutorial explains the various aspects of the Docker Container service. Starting with the basics of Docker which focuses on the installation and configuration of Docker, it gradually moves on to advanced topics such as Networking and Registries. The last few chapters of this tutorial cover the development aspects of Docker and how you can get up and running on the development environments using Docker Containers.

Audience

This tutorial is meant for those who are interested in learning Docker as a container service. This product has spread like wildfire across the industry and is really making an impact on the development of new generation applications. So anyone who is interested in learning all the aspects of Docker should go through this tutorial.

Prerequisites

The prerequisite is that the readers should be familiar with the basic concepts of Windows and the various programs that are already available on the Windows operating system. In addition, it would help if the readers have some exposure to Linux.

Overview

Docker is a container management service. The keywords of Docker are developed, ship, and run anywhere. The whole idea of Docker is for developers to easily develop applications, ship them into containers which can then be deployed anywhere.

The initial release of Docker was in March 2013 and since then, it has become the buzzword for modern world development, especially in the face of Agile-based projects.

Features of Docker

  • Docker has the ability to reduce the size of development by providing a smaller footprint of the operating system via containers.
  • With containers, it becomes easier for teams across different units, such as development, QA and Operations to work seamlessly across applications.
  • You can deploy Docker containers anywhere, on any physical and virtual machines and even on the cloud.
  • Since Docker containers are pretty lightweight, they are very easily scalable.

Components of Docker

Docker has the following components

  • Docker for Mac โˆ’ It allows one to run Docker containers on the Mac OS.
  • Docker for Linux โˆ’ It allows one to run Docker containers on the Linux OS.
  • Docker for Windows โˆ’ It allows one to run Docker containers on the Windows OS.
  • Docker Engine โˆ’ It is used for building Docker images and creating Docker containers.
  • Docker Hub โˆ’ This is the registry which is used to host various Docker images.
  • Docker Compose โˆ’ This is used to define applications using multiple Docker containers.

We will discuss all these components in detail in the subsequent chapters.

The official site for Docker is https://www.docker.com/ The site has all information and documentation about the Docker software. It also has download links for various operating systems.
