          privileged: true
        volumeMounts:
          - mountPath: /dev
            name: dev
          - mountPath: /lib/modules
            name: modules
      volumes:
      - name: dev
        hostPath:
          # directory location on host
          path: /dev
      - name: modules
        hostPath:
          # directory location on host
          path: /lib/modules

you should change the corresponding images and imagePullPolicy.
