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.

Using the Build Pipeline plugin

We have seen the built-in pipeline concept of Jenkins 2. It is a very flexible and powerful concept, but for that, we need to write a Groovy script. Another way that has an easy learning curve is to use the Build Pipeline plugin. It provides simple visualization of upstream and downstream build jobs. It also enables manual triggers for a situation where we need approval for executing a specific build. We can create a chain of jobs for end-to-end automation. Here, I'm assuming that you are aware of the concept of upstream and downstream build jobs.

To create a build pipeline, follow these steps:

  1. Install the Build Pipeline plugin.

  2. On the Jenkins dashboard, click on the plus sign, which will open a page to create a Build Pipeline View. Provide a View name for the build pipeline, and click on OK:

  3. It is important to configure upstream and downstream build jobs:

We have created multiple build jobs to compile the source code, verify the source code using Sonar, and...
