Using Pipeline Templates

Create a Job from Pipeline Template Catalog

In this lab you will create a new Multibranch Pipeline job from the Maven Pipeline Template provided by a Pipeline Template Catalog. And just by filling in a few parameters of a Pipeline template, you will quickly have a complete continuous integration pipeline for your application that meets the required standards of your organization.

1. On your CloudBees CI Managed Controller (Jenkins instance) navigate into the template-jobs folder.
2. Click on the New Item link in the left navigation menu.
3. Enter simple-maven-app as the Item Name, select Maven Pipeline Template as the item type and then click the OK button.
4. On the next screen, fill in the GitHub Organization template parameter with the name of the GitHub Organization you created for this workshop (all the other default values should be correct) and then click the Save button.
5. After you click the Save button the Multibranch Pipeline project (created by the template) will scan your simple-java-maven-app repository, creating a Pipeline job for each branch where there is a marker file that matches cloudbees-ci.yml (or in this case, just the main branch). Click on the Scan Repository Log link in the left menu to see the results of the branch indexing scan.
6. Next, click on the simple-maven-app link in the menu at the top of page and you will see that there were no jobs created under the Branches or the Pull Requests. The reason is because the Maven Pipeline Template requires a marker file in each branch of the target repository that you want to be built by the template.
   • As you can see in the excerpt below, the Maven Pipeline Template specifies a markerFile (for details see Using a custom marker file with templates) with a value of cloudbees-ci.yml in its template.yaml configuration (excerpt below taken from the templates/maven/template.yaml file you can find in your copy of the pipeline-template-catalog repository in your workshop GitHub Organization):

   version: 1
   type: pipeline-template
   name: Maven Pipeline Template
   templateType: MULTIBRANCH
   description: Provides a pipeline template for maven builds.
   parameters:
   ...
   multibranch:
     markerFile: cloudbees-ci.yml 
     branchSource:
       github:
       ...
   

7. Now, in GitHub, navigate to your simple-java-maven-app repository in the GitHub Organization you created for this workshop, click on the example.cloudbees-ci.yml file, then click pencil icon to edit the file and then rename the file by deleting example. from the beginning of the file name, leaving just cloudbees-ci.yml.
8. Scroll to the bottom of the page and click the Commit changes (directly to the main branch) button to commit the renamed cloudbees-ci.yml to the main branch of your simple-java-maven-app repository.
9. Navigate back to the simple-maven-app Multibranch Pipeline on your CloudBees CI Managed Controller and you will see that there is now a main branch job.
