Creating Deployment for Attaching Claimed Volumes to Pods

Creating Deployment for Attaching Claimed Volumes to Pods

In this lesson, we will create a Jenkins deployment for attaching claimed volumes to pods and look into the sequence of associated events.

        ...
      volumes:
      - name: jenkins-home
