If you're on GKE, you should already have dynamic provisioning setup.

  storageClassName: do-block-storage
  accessModes:
    - ReadWriteOnce

"do-block-storage"? Were you running on Digital Ocean previously? You should be able remove the storageClassName line and use the default provisioner Google provides.

For example, here's a snippet from one of my own statefulsets

  volumeClaimTemplates:
  - metadata:
      name: data
    spec:
      accessModes: [ "ReadWriteOnce" ]
      ## Specify storage class to use nfs (requires nfs provisioner. Leave unset for dynamic provisioning)
      #storageClassName: "nfs"
      resources:
        requests:
          storage: 10G

I do not specify a storage class here, so it uses the default one, which provisions as a persistent disk on GCP

$ kubectl get storageclass
NAME                 PROVISIONER            RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
standard (default)   kubernetes.io/gce-pd   Delete          Immediate           false                  2y245d
