Jenkins 2: Beyond the basics

Honing your pipeline skills with Jenkinsfiles, Declarative Pipelines, and Blue Ocean

Brent Laster

Jenkins, the industry-standard continuous delivery (CD) orchestrator, has evolved. In Jenkins 2, pipelines are now written as structured code with a rich, descriptive DSL (pipelines as code) and use powerful features to automate and simplify CD job chains.

Brent Laster takes you beyond the basics of pipeline as code, teaching you how to use Declarative Pipeline and Blue Ocean—alternative methods available in Jenkins 2—to simplify your pipeline scripts. Along the way, you’ll learn how to convert to and use Jenkinsfile to have Jenkins automatically create and execute jobs for you based on your source code repository and explore advanced functionality such as parallelism in pipelines.

What you'll learn-and how you can apply it

By the end of this live, online course, you’ll understand:

  • Declarative Pipeline and Blue Ocean, alternatives to pipeline as code in Jenkins 2
  • Advanced Jenkins 2 functionality such as parallelism in pipelines

And you’ll be able to:

  • Use Declarative Pipeline and Blue Ocean to simplify your pipeline scripts
  • Use Jenkinsfiles to automatically create and execute jobs

This training course is for you because...

  • You’re a Jenkins user or support person with investments in the traditional Jenkins model, and you need to understand the Jenkins 2 model.
  • You're a developer or tester with dependencies on Jenkins processing, and you want to learn what value Jenkinsfiles, Declarative Pipelines, and Blue Ocean provide.

Prerequisites

  • Experience working with the traditional Jenkins model
  • Basic familiarity with continuous delivery pipeline concepts
  • A working knowledge of Git (useful but not required)
