Learning Jenkins

This is the repository for the LinkedIn Learning course Learning Jenkins. The full course is available from LinkedIn Learning.

Do you need to automate tasks as part of your software development, system administration, or engineering work? This course introduces you to Jenkins, a highly configurable application used to automate software development and system administration tasks, and helps you build confidence in using it. Jenkins is a key DevOps tool, along with Docker and Git. Instructor Michael Jenkins covers how to set up a personal installation of Jenkins and familiarize yourself with the program’s interface. Next, Michael steps through how to configure your first job in Jenkins. After you get some experience with jobs, he explains the Jenkins plugin environment and how plugins are used to extend the functionality that Jenkins offers. Finally, Michael wraps up with detailed instructions on organizing jobs in folders and views, as well as a brief look into creating pipelines as code.

Instructions

This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.

Branches

The branches are structured to correspond to the videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter. Some branches will have a beginning and an end state. These are marked with the letters b for "beginning" and e for "end". The b branch contains the code as it is at the beginning of the movie. The e branch contains the code as it is at the end of the movie. The main branch holds the final state of the code when in the course.
