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.

Installing and configuring a Chef workstation

Before installing a Chef client for preparing a workstation, let's try to verify whether the Chef client has been installed:

  1. Execute the chef-client -version command to verify whether the Chef client has been installed:

                [mitesh@devops1 Desktop]$ chef-client -version
                bash: chef-client: command not found

  2. As you can see in the output of the previous command, the Chef client is not installed. Now, navigate to the directory where the Chef client installable is stored using the cd command:

                [mitesh@devops1 Desktop]$ cd chef/
                [mitesh@devops1 chef]$ ls

  3. Run the downloaded Chef client RPM using rpm -ivh chef-<version>.rpm:

                [mitesh@devops1 chef]$ rpm -ivh chef-12.9.41-1.el6.x86_64.rpm
                warning: chef-12.9.41-1.el6.x86_64.rpm: Header V4DSA/SHA1 Signature,                 key ID 83ef826a:...
