title: Kubernetes Job Cleanup
body: <p>From what I understand the Job object is supposed to reap pods after a certain amount of time.
  But on my GKE cluster (Kubernetes 1.1.8) it seems that "kubectl get pods -a" can list pods from days ago. </p>
  
  <p>All were created using the Jobs API.</p>
  
  <p>I did notice that after delete the job with
      kubectl delete jobs
  The pods were deleted too.</p>
  
  <p>My main concern here is that I am going to run thousands and tens of thousands of pods on the cluster in batch jobs, and don't want to overload the internal backlog system.</p>
