apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: hello
spec:
  schedule: "*/1 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: hello
            image: busybox
            args:
            - /bin/sh
            - -c
            - date; echo Hello from a CronJob
          restartPolicy: OnFailure
          volumeMounts:
            - mountPath: /downlods
              name: downloads
          dnsPolicy: ClusterFirst
          schedulerName: default-scheduler
          securityContext: {}
          terminationGracePeriodSeconds: 30
          volumes:
          - name: downloads
            persistentVolumeClaim:
              claimName: portal-downloads

---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: portal-downloads
  labels:
    app: cronjob
spec:
  accessModes:
    - ReadWriteOnce
  resources:
