Mastering Jenkins

By: jmcallister -, Jonathan McAllister

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.

Chapter 2. Distributed Builds – Master/Slave Mode

A basic Jenkins installation operates as a standalone entity. A single Jenkins master can be responsible for source control polling, LDAP authentication, job execution, test report parsing, and more. As the role Jenkins plays in an organization expands, we may be asked to provide support for additional build environments, automated test execution solutions, configuration management solutions, and even deployments. To extend Jenkins and support these types of additional responsibilities, Jenkins features an elegant distributed build solution. This feature can be leveraged to help offload some of the work and to position Jenkins as a scalable, cross-platform solution.

Distributed builds in Jenkins are supported by slave agent services running on unique devices, which coins the term master and slave mode. The master/slave mode architecture can assist us in scaling Jenkins from a single...
