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.

However, it is extremely vital to be aware of failure or at least to know when things fail so we can fix them and get rid of issues.

Notifications are always helpful in case of failures. Consider a scenario where a build failure or test case failure has to be notified to a specific set of stakeholders. In such a situation, it is desirable to have e-mail notifications.

We will use G-mail configuration for setting up e-mail notifications. Follow these steps:

  1. Go to https://www.google.com/settings/u/1/security/lesssecureapps and click on Turn on Access for less secure apps, as shown here, to send e-mail notifications from Jenkins 2:

  2. Do the following from the Jenkins dashboard:

    1. Click on Manage Jenkins, and go to the Configure System section.

    2. Go to the E-mail Notification subsection and enter the appropriate values for SMTP Server and Default user...
