Docker and Jenkins [as Code]
Hands-on Jenkins configuration management with Docker, Kubernetes, Configuration as Code, and Groovy hooks.
Slides
Abstract
How can you make a Jenkins installation reproducible, portable, and easier to maintain? In this hands-on workshop, we manage Jenkins configuration as code and run Jenkins with Docker and Kubernetes. We explore controller and agent images, build a custom Jenkins image, and manage its plugins and configuration alongside the code.
Participants use Jenkins Configuration as Code (JCasC) to define settings in YAML and Groovy hooks to customize initialization where needed. We discuss how the two approaches work together, how to handle configuration changes, and how container images and Kubernetes agents fit into a repeatable Jenkins setup.
The workshop can be adapted to a duration of 2 to 8 hours, from an introduction to a deeper, hands-on exploration.
Workshop chapters#
- Jenkins configuration as code: Explore the components of a Jenkins installation and the benefits of storing configuration alongside code.
- Jenkins with Docker: Run controller and agent images, build a custom Jenkins image, and manage its plugins.
- Jenkins Configuration as Code: Define and apply Jenkins settings with JCasC and YAML, and manage configuration changes.
- Groovy hooks: Customize Jenkins initialization with Groovy and combine hooks with JCasC where additional flexibility is needed.
- Jenkins on Kubernetes: Explore containerized Jenkins deployments and Kubernetes agents as part of a repeatable setup.
The depth and hands-on exercises in each chapter can be adapted to the available time.
