GCS Fuse CSI Driver not auto loading to CronJob in GKE

[ravi_p]

 am trying to use
gke-gcsfuse/volumes: "true"  in CronJob, but there is no provision as well as documentation available to use the csi driver. 

The only documentation is https://cloud.google.com/kubernetes-engine/docs/how-to/persistent-volumes/cloud-storage-fuse-csi-dri... which doesnot look feasible for CronJob.

What can we do for loading csi fuse driver with Cron Job?

My CronJob looks like:

apiVersion: batch/v1
kind: CronJob
metadata:
  name: hello
  namespace: my-namespace
spec:
  schedule: "*/1 * * * *"
  concurrencyPolicy: Allow
  startingDeadlineSeconds: 100
  suspend: false
  successfulJobsHistoryLimit: 3
  failedJobsHistoryLimit: 1
  jobTemplate:
    spec:
      template:
        metadata:
          spec:
             containers:
                - name: hello 
                  image: busybox 
                  args: 
                    - /bin/sh 
                    - -c - date; echo "Hello, World!" 
                  volumeMounts: 
                    - mountPath: /cron-jobs 
                      name: cron-scripts 
               restartPolicy: OnFailure 
               serviceAccount: k8-prod-service-account 
               volumes: 
                  - name: cron-scripts 
                    persistentVolumeClaim: 
                       claimName: cronjob-gcs-data-claim

Hello @ravi_p,

Thank you for contacting Google Cloud Community.

I believe that you have self resolved your issue by appending a Job template in CronJob Schema. Example cornjob YAML manifest:

apiVersion: batch/v1
kind: CronJob
metadata:
  name: hello
  namespace: my-namespace
spec:
  schedule: "*/1 * * * *"
  concurrencyPolicy: Allow
  startingDeadlineSeconds: 100
  suspend: false
  successfulJobsHistoryLimit: 3
  failedJobsHistoryLimit: 1
  jobTemplate:
    spec:
      template:
        metadata:
          annotations:
            gke-gcsfuse/volumes: "true"
        spec:
          serviceAccount: my-k8-service-account
          containers:
            - name: hello
              image: busybox
              args:
                - /bin/sh
                - -c
                - date; echo "Hello, World!"
              volumeMounts:
                - mountPath: /cron-jobs
                  name: cron-scripts
          restartPolicy: OnFailure
          volumes:
          - name: cron-scripts
            persistentVolumeClaim:
              claimName: cronjob-gcs-data-claim
