⇒ Jenkins is a powerful automation server that facilitates Continuous Integration and Continuous Deployment (CI/CD). In this guide, we will explore several key Jenkins concepts, including Linked Projects, Views, User Management, and the Master-Slave Concept. We will provide clear explanations, structured steps, and lab instructions for each topic.

Linked Projects in Jenkins:

Understanding Linked Projects ⇒

Jenkins allows projects (jobs) to be connected using Upstream and Downstream relationships. This feature helps in automating workflows where one job triggers another based on build success.

• Upstream Project: A job that triggers another job after completion.
• Downstream Project: A job that is triggered by another job.

Lab Instructions

→ Continuing from the previous lab on the 3rd page

1. Open Google Chrome and go to localhost:8080.
2. Login to Jenkins.
3. Create JobA (Upstream Job):

   • Click on "New Item" → Enter the name as JobA → Click OK.

   • Go to the Build section → Enter the command:

     echo "Hello"
     

   • Click Save.

4. Configure JobA to trigger another job after completion:
   • Go to Dashboard → Click on JobA → Click on Configure.
   • Scroll down to Post-build Actions → Click on Add Post-build Action.
   • Select "Build other project" → Enter the name of another previously created job.
   • Choose "Trigger only if build is stable" → Click Save.
5. Execute JobA:
   • Go to Dashboard → Click on JobA → Click Build Now.
   • Observe the Build Queue, where the next job starts building automatically after JobA finishes.

This demonstrates Upstream Linked Projects.
