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.

We want to create an end-to-end pipeline where the application source files are compiled, unit tests are executed, package file is created, a new virtual machine created, runtime environment is setup, and deployment is performed. Chef in our context plays a vital role, considering its many uses. We are going to use it for setting up our runtime environment and standardizing the process of configuration management rather than implementing a customized way to install tools using scripts. Centralized configuration management makes it easy to control and configure resources without complication.

This chapter describes in detail the configuration management tool Chef, the installation of its components and alternatives...
