Scenario

A Job manifest at /home/interview/fail-job.yaml is failing with a non-zero exit status. The Job has limited retries configured.

Task

Fix the Job so it completes successfully.

Step 1: Check the failing job

kubectl get jobs -n batch
kubectl describe job fail-job -n batch

You'll see the job has Failed status with backoffLimit reached.

Step 2: Examine the job manifest

cat /home/interview/fail-job.yaml

Note the command exit 1 causes the failure. It should be echo 'Success'; exit 0.

Step 3: Delete the failed job

kubectl delete job fail-job -n batch

Jobs with immutable pod template specs require deletion before reapplication.

Step 4: Edit the job manifest to fix the command

nano /home/interview/fail-job.yaml

Change the command from exit 1 to echo 'Success'; exit 0:

command: ["sh", "-c", "echo 'Success'; exit 0"]

Save and exit (Ctrl+O, Enter, Ctrl+X).

Step 5: Apply the fixed job

kubectl apply -f /home/interview/fail-job.yaml

Step 6: Verify job completes successfully

kubectl get jobs -n batch
kubectl logs job/fail-job -n batch

Job should show 1/1 completions and logs should display "Success".
