Dynamic vs statis volume z2jh

Hi,

What is the difference between dynamic vs static volumes in z2jh supposed to be? Here is the source code:

storage_type = get_config("singleuser.storage.type")
if storage_type == "dynamic":
    pvc_name_template = get_config("singleuser.storage.dynamic.pvcNameTemplate")
    c.KubeSpawner.pvc_name_template = pvc_name_template
    volume_name_template = get_config("singleuser.storage.dynamic.volumeNameTemplate")
    c.KubeSpawner.storage_pvc_ensure = True
    set_config_if_not_none(
        c.KubeSpawner, "storage_class", "singleuser.storage.dynamic.storageClass"
    )
    set_config_if_not_none(
        c.KubeSpawner,
        "storage_access_modes",
        "singleuser.storage.dynamic.storageAccessModes",
    )
    set_config_if_not_none(
        c.KubeSpawner, "storage_capacity", "singleuser.storage.capacity"
    )

    # Add volumes to singleuser pods
    c.KubeSpawner.volumes = [
        {
            "name": volume_name_template,
            "persistentVolumeClaim": {"claimName": pvc_name_template},
        }
    ]
    c.KubeSpawner.volume_mounts = [
        {
            "mountPath": get_config("singleuser.storage.homeMountPath"),
            "name": volume_name_template,
        }
    ]
elif storage_type == "static":
    pvc_claim_name = get_config("singleuser.storage.static.pvcName")
    c.KubeSpawner.volumes = [
        {"name": "home", "persistentVolumeClaim": {"claimName": pvc_claim_name}}
    ]

    c.KubeSpawner.volume_mounts = [
        {
            "mountPath": get_config("singleuser.storage.homeMountPath"),
            "name": "home",
            "subPath": get_config("singleuser.storage.static.subPath"),
        }
    ]

Dynamic volumes are a kubernetes feature that means you can obtain storage volumes on demand, instead of having to provision “static” storage in advance, or manually, as you’d typically do on-prem:
