In Detail

In agile development practices, developers need to integrate their work frequently to fix bugs or to create a new feature or functionality. Jenkins is used specifically for Continuous Integration, helping to enforce the principles of agile development. This book focuses on the latest and stable release of Jenkins (2.5 and later), featuring the latest features, such as Pipeline as Code, the new setup experience, and the improved UI. With the all-new Pipeline as Code feature, you will be able to build simple or advanced pipelines easily and rapidly, hence improving your teams' productivity.

This book begins by tackling the installation of the necessary software dependencies and libraries you'll need to perform Continuous Integration for a Java application. From there, you'll integrate code repositories, applications, and build tools for the implementation of Continuous Integration.

Finally, you will also learn how to automate your deployment on cloud platforms such as AWS and Microsoft Azure, along with a few advanced testing techniques.

Style and approach

This book provides simple, step-by-step instructions, taking you from start to finish in accomplishing real-world Continuous Integration and Continuous Delivery tasks.

"I've missed more than 9,000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game-winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."-Michael Jordan.

I've always thanked a lot of people who have been instrumental in contributing to my life's journey up to now, but I guess it's time to really acknowledge that One person who has been with me as long as I can remember.

With this book, I would like to thank the one and only invisible yet omnipresent Almighty. We share a mutual love and hate relationship and I really value it. You were always there equally during my good and bad times and without you, I wouldn't have made it this far!

Last but not the least, I want to thank all who taught me how to love myself, first!

About the Reviewers

Stefan Lapers started his career almost 20 years ago as an IT support engineer and quickly grew into Linux/Unix system engineering and software development.

Over the years he accumulated experience deploying and maintaining hosted application solutions while working for great customers such as MTV, TMF, and many more. In more recent years, he was involved in multiple development projects and their delivery as a service on the internet.

In his spare time, he enjoys his family and building/flying RC helicopters.

Preface

Jenkins has been used specifically for Continuous Integration over the years. Continuous Integration systems are a vital part of Agile teams because they help enforce the principles of Agile development.

Jenkins, a continuous build tool, enables Agile teams to focus on work and innovations by automating the build, artifact management, and deployment processes, rather than worrying about manual processes. However, the release of Jenkins 2.0 and later versions are focused on Continuous Delivery.

Jenkins is an open source automation server. Continuous Integration is a significant part of DevOps culture and hence many open source and commercial tools for Continuous Delivery utilizes Jenkins for a complete product.

DevOps is a buzzword in 2015 and for coming years as per Market trends by various research firms. Continuous Integration is a significant part of DevOps culture and hence the trend to use Jenkins will increase in future. If Continuous Integration is the base, then Continuous Delivery is the topping. Jenkins supports and focus more on end-to-end automation of application life cycle management system.

What this book covers

Chapter 1, Exploring Jenkins, describes in detail the basics of Continuous Integration and an overview of Jenkins. It describes the recent growth of importance of Continuous Integration as a practice to cultivate DevOps culture. This chapter also describes the installation and configuration of Jenkins. We are going to take a whistle-stop tour through some of the key features of Jenkins, and plugin installation as well.

Chapter 2, Installation and Configuration of Code Repositories and Build Tools, describes in detail how to prepare the runtime environment for application life cycle management and configure it with Jenkins - the open source continuous integration tool. It will cover how to integrate Eclipse and Jenkins, so builds can be run from Eclipse as well.

Chapter 3, Managing Code Quality and Notifications, will cover how to integrate static code analysis behavior into Jenkins. Code quality is an extremely vital feature that impacts on applications' effectiveness and by integrating it with Sonar, users get insights into problematic portions of code. This chapter also covers email notifications on build status.

Chapter 4, Continuous Integration with Jenkins, describes in detail how to create and configure build jobs in Java, how to run build jobs, unit test cases using Ant, and Maven build tools. It covers all aspects of running a build to create a distribution file or war file for deployment.

Chapter 5, Continuous Delivery - Implementing Automated Deployment, provides insights into how functional testing and load testing can be performed and how they can be integrated with Jenkins to adopt the Continuous Testing practices of DevOps culture.

Chapter 6,
