How to mount PVC to a (katib) Job specification?-CodePudding

I'd like to mount a PVC to a (katib) Job specification but can't find anything in the documentation nor any example?

I'm pretty sure that this should be possible as a Job is orchestrating pods and pods can do so. Or am I missing something?

Please find below the respective (katib) job specification

apiVersion: batch/v1
kind: Job
spec:
  template:
    spec:
      containers:
      - env:
        - name: training-container
          image: docker.io/romeokienzler/claimed-train-mobilenet_v2:0.3
          command:
            - "ipython"
            - "/train-mobilenet_v2.ipynb"
            - "optimizer=${trialParameters.optimizer}"
      restartPolicy: Never

CodePudding user response：

You can add the volume and volume mount to your Katib job template so that all the HPO jobs on Katib can share the same volumes. e.g.

apiVersion: batch/v1
kind: Job
spec:
  template:
    spec:
      containers:
        - name: training-container
          image: docker.io/romeokienzler/claimed-train-mobilenet_v2:0.4
          command:
            - "ipython"
            - "/train-mobilenet_v2.ipynb"
            - "optimizer=${trialParameters.optimizer}"
          volumeMounts:
            - mountPath: /data/
              name: data-volume
      restartPolicy: Never
      volumes:
          - name: data-volume
            persistentVolumeClaim:
              claimName: data-pvc

Also make sure your pvc is read write many so the pod on different nodes can mount on the same volume at the same time.
