Jenkins Administrator's Guide

By: Calvin Sangbin Park, Lalit Adithya, Sam Gleske

Overview of this book

Jenkins is a renowned name among build and release CI/CD DevOps engineers because of its usefulness in automating builds, releases, and even operations. Despite its capabilities and popularity, it's not easy to scale Jenkins in a production environment. Jenkins Administrator's Guide will not only teach you how to set up a production-grade Jenkins instance from scratch, but also cover management and scaling strategies. This book will guide you through the steps for setting up a Jenkins instance on AWS and inside a corporate firewall, while discussing design choices and configuration options, such as TLS termination points and security policies. You’ll create CI/CD pipelines that are triggered through GitHub pull request events, and also understand the various Jenkinsfile syntax types to help you develop a build and release process unique to your requirements. For readers who are new to Amazon Web Services, the book has a dedicated chapter on AWS with screenshots. You’ll also get to grips with Jenkins Configuration as Code, disaster recovery, upgrading plans, removing bottlenecks, and more to help you manage and scale your Jenkins instance. By the end of this book, you’ll not only have a production-grade Jenkins instance with CI/CD pipelines in place, but also knowledge of best practices by industry experts.

Retrospective

JCasC is a powerful tool with active development still in progress. It gets a lot of the configurations codified, and while it's not perfect, it's almost there.

With the vast number of plugins in the Jenkins ecosystem, of course it's a challenge to wrangle every developer to make their plugins compatible with JCasC. It's disappointing when a plugin as popular as GHPRB still doesn't fully support JCasC, but GHPRB developers are aware of the missing feature and are working on addressing it3. For the people who really want to automate GHPRB configuration, the Configuration as Code Plugin - Groovy Scripting Extension plugin is available to fill the gap.

Also, Jenkins developers are working on the credentials import/export issue4, so I think that in a couple more years JCasC will reach its full potential. As a CI/CD engineer who uses Ansible and dozens of Groovy scripts to manage Jenkins, I eagerly look forward to JCasC being completed...
