Overview of this book

With the software industry becoming more and more competitive, organizations are now integrating delivery automation and automated quality assurance practices into their business model. Jenkins represents a complete automation orchestration system, and can help converge once segregated groups into a cohesive product development and delivery team. By mastering the Jenkins platform and learning to architect and implement Continuous Integration, Continuous Delivery, and Continuous Deployment solutions, your organization can learn to outmanoeuvre and outpace the competition. This book will equip you with the best practices to implement advanced continuous delivery and deployment systems in Jenkins. The book begins with giving you high-level architectural fundamentals surrounding Jenkins and Continuous Integration. You will cover the different installation scenarios for Jenkins, and see how to install it as a service, as well as the advanced XML configurations. Then, you will proceed to learn more about the architecture and implementation of the Jenkins Master/Save node system, followed by creating and managing Jenkins build jobs effectively. Furthermore, you'll explore Jenkins as an automation orchestration system, followed by implementing advanced automated testing techniques. The final chapters describe in depth the common integrations to Jenkins from third-party tools such as Jira, Artifactory, Amazon EC2, and getting the most out of the Jenkins REST-based API. By the end of this book, you will have all the knowledge necessary to be the definitive resource for managing and implementing advanced Jenkins automation solutions for your organization.

Job execution


When a job execution fails, the Jenkins system provides a set of comprehensive tools that can help us investigate the details of the failure. To get the most out of the Jenkins system, users will need to become familiar with the basic operations of the project status page and learn how to investigate build information efficiently.

The first step in investigating any job run failures is to understand the contents of the Build History panel and locate the build that requires further investigation. Failed builds are noted with a red sphere next to the associated execution, and successful executions are noted with a blue sphere (unless you are using the greenballs plugin). You can click on executions from the Build History panel to navigate to the detailed execution status page for the specified run, as shown in Figure 4-12:
