String parameters are the best way to pass unstructured text into a Jenkins job. This lesson shows how to configure a string parameter and then access the value in a build step.
- [Instructor] Let's add a string parameter…to our apache-ivy job for a version number.…Then we'll modify the job to echo…this version number during the build.…So I'll start by selecting apachy-ivy…and picking configure.…Then I'll select this project is parameterized.…Under add parameter I'll select string parameter…and enter the name VERSION_NUMBER.…If you're following along an exercise file is provided…with the commands that I'm typing in this build step.…
I can also provide a default value.…This is useful for specifying sane default for the job…and also can save some time typing…if you find yourself running the job multiple times.…I'll enter 1.0.0 for the default.…The description gets displayed when the job is run…and is useful for providing information…about the type of information the user should enter.…In this case I'll tell the user to enter a version number.…Now let's use this parameter in a build step.…
If I go to build environment, add build step,…and execute shell.…I'm going to specify a bash interpreter and enter my script.…

4/17/2018First, learn how to set up Jenkins on Mac, Windows, Linux, or inside a Docker container, and find out how Jenkins plugins are used to extend its functionality. Next, configure your first job step by step, leading up to the requisite "Hello, World" output, and learn to make your jobs more useful and portable with parameters. Then explore job scheduling, and Jenkins's convenient aliases for running jobs at regular intervals. The course wraps up with tips for organizing jobs in folders and views and a brief look into pipelines as code-which enable you to execute a series of jobs in stages.
By the end of the training, you should be able to install Jenkins locally or on a virtual machine, create a Jenkins jobs that can be triggered manually or on a schedule, and install and configure plugins to extend the Jenkins framework.
