Overview of this book

The DevOps culture is growing at a massive rate, as many organizations are adopting it. However, implementing it for web applications is one of the biggest challenges experienced by many developers and admins, which this book will help you overcome using various tools, such as Chef, Docker, and Jenkins. On the basis of the functionality of these tools, the book is divided into three parts. The first part shows you how to use Jenkins 2.0 for Continuous Integration of a sample JEE application. The second part explains the Chef configuration management tool, and provides an overview of Docker containers, resource provisioning in cloud environments using Chef, and Configuration Management in a cloud environment. The third part explores Continuous Delivery and Continuous Deployment in AWS, Microsoft Azure, and Docker, all using Jenkins 2.0. This book combines the skills of both web application deployment and system configuration as each chapter contains one or more practical hands-on projects. You will be exposed to real-world project scenarios that are progressively presented from easy to complex solutions. We will teach you concepts such as hosting web applications, configuring a runtime environment, monitoring and hosting on various cloud platforms, and managing them. This book will show you how to essentially host and manage web applications along with Continuous Integration, Cloud Computing, Configuration Management, Continuous Monitoring, Continuous Delivery, and Deployment.

In this chapter, we had an overview of Docker containers, architecture details, and details of the main components of Docker, including a quick overview of Docker Hub. Based on the overview, we tried to compare virtual machines with Docker containers to gain a clear picture of why containers have recently been gaining traction.

After gaining some understanding of virtual machines and containers, we covered the process of installing Docker on a CentOS 6.x virtual machine. We created a hello-world container and Ubuntu and CentOS containers from the images available on Docker Hub.

Our main aim is to use a Tomcat container for deploying a sample Spring application, so we used a Tomcat image and created a container from it for verification. To gain more understanding, we used a Dockerfile to build an image with Java and Tomcat.

On the subject of containers, this quote by Ted Engstrom is quite suitable:

"Anything that is wasted effort represents wasted time. The best management of our time...
