CloudBees CI - Cross Team Collaboration

Enable Cross Team Collaboration Notifications

  1. Navigate to the top-level of your Team Master and click on Manage Jenkins in the left menu.

  2. On the Manage Jenkins page scroll down and click on the Configure Notification link.

  3. Check the Enabled checkbox, select Local Only as the Notification Router Implementation and click the Save button.

Adding an event trigger

  1. In GitHub, navigate to the Add event trigger pull request (#1) in your fork of the pipeline-template-catalog repository.

  2. To see the changes that will be made to your copy of the VueJS template, click on the Files changed tab and scroll down to see the differences.

  3. We are adding the eventTrigger using jmespathQuery and adding a new stage where we are using the getImageBuildEventPayload Pipeline Shared Library step to extract the event payload.
  4. Once you have reviewed the changes, click back on the Conversation tab and then click the green Merge pull request button and then the Confirm merge button.
  5. Next, to ensure that we are using the updated VueJS template, we will re-import the Pipeline Template Catalog you just updated. Navigate to the top-level of your Team Master and click on Pipeline Template Catalogs in the left menu and then click the workshopCatalog link.

  6. Finally, in order to enable the trigger on your microblog-frontend Pipeline jobs you need to run the job once - so navigate to the master branch job for the microblog-frontend Mutlibranch project and click the Build Now link in the left menu.
  7. After the VueJS template is loaded the job configuration for your master branch job will be updated to reflect the addition of the event trigger.

Create a Pipeline to publish an event

Now that you have an eventTrigger added to your VueJS template we need to create a job that will publish an event that will trigger it. Each of you will create a simple Pipeline job that will publish an event to imitate the real world scenario where a new node base image would be built and pushed - typically by another team on a different Team Master.

  1. On your Team Master and ensure that you are in the folder with the same name as your Team Master - you should see the core-workshop-setup Pipeline job.
  2. Click on the New Item link in the left navigation menu - again, make sure that you are in the folder with the same name as your Team Master, and not at the root of your Team Master.
  3. Enter an item name - say publish-event - then select Pipeline as the item type and then click the OK button.

  4. Copy the following Pipeline and paste it into the Script text area and click the Save button:

    pipeline {
agent none
options {
    timeout(time: 30, unit: 'MINUTES')
}
stages {
    stage('Publish Event') {
        steps {
            publishEvent event: jsonEvent('{"event":"imagePush","name":"node","tag":"14.0.0-alpine3.11"}')
        }
    }
}
}

  1. Click the Build Now link in the left menu.

  2. Once the publish-event Pipeline job completes successfully you will see your job for the microblog-frontend Mutlibranch project triggered.
  3. Once the master branch job completes successfully you can see in the logs: Resolved base name $NODE_IMAGE to node:14.0.0-alpine3.11 as specified by the event you published above.
