Could not get the cronjob running on the image

[lucheeseng827]

Hi there, I am planning to use the image as the cronjob for my kubernetes pods which are marked as completed.

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: cleanup-prod
spec:
  schedule: "*/20 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: kubectl-runner
            image: werner/kubectl
            command: ["sh", "-c", "kubectl delete pods -n test-prod $(kubectl get pods -n test-prod |grep 'Completed'| awk '$3 ' | awk '{print $1}')"]
          restartPolicy: Never

when log from the pods/cronjob

kubectl logs  cleanup-prod-156kd  -n default
