  # @!attribute [rw] allowed_locations
  #   @return [::Array<::String>]
  #     A list of allowed location names represented by internal URLs.
  #
  #     Each location can be a region or a zone.
  #     Only one region or multiple zones in one region is supported now.
  #     For example,
  #     ["regions/us-central1"] allow VMs in any zones in region us-central1.
  #     ["zones/us-central1-a", "zones/us-central1-c"] only allow VMs
  #     in zones us-central1-a and us-central1-c.
  #
  #     All locations end up in different regions would cause errors.
  #     For example,
  #     ["regions/us-central1", "zones/us-central1-a", "zones/us-central1-b",
  #     "zones/us-west1-a"] contains 2 regions "us-central1" and

  # A new persistent disk or a local ssd.
  # A VM can only have one local SSD setting but multiple local SSD partitions.
  # See https://cloud.google.com/compute/docs/disks#pdspecs and
  # https://cloud.google.com/compute/docs/disks#localssds.
  # @!attribute [rw] image
  #   @return [::String]
  #     URL for a VM image to use as the data source for this disk.
  #     For example, the following are all valid URLs:
  #
  #     * Specify the image by its family name:
  #     projects/\\{project}/global/images/family/\\{image_family}
  #     * Specify the image version:
  #     projects/\\{project}/global/images/\\{image_version}
  #
  #     You can also use Batch customized image in short names.
  #     The following image values are supported for a boot disk:
  #
  #     * `batch-debian`: use Batch Debian images.
  #     * `batch-centos`: use Batch CentOS images.
  #     * `batch-cos`: use Batch Container-Optimized images.
  #     * `batch-hpc-centos`: use Batch HPC CentOS images.
  #     * `batch-hpc-rocky`: use Batch HPC Rocky Linux images.
  # @!attribute [rw] snapshot
  #   @return [::String]
  #     Name of a snapshot used as the data source.
  #     Snapshot is not supported as boot disk now.
  # @!attribute [rw] type
  #   @return [::String]
  #     Disk type as shown in `gcloud compute disk-types list`.
  #     For example, local SSD uses type "local-ssd".
  #     Persistent disks and boot disks use "pd-balanced", "pd-extreme", "pd-ssd"
  #     or "pd-standard".
  # @!attribute [rw] size_gb
  #   @return [::Integer]
  #     Disk size in GB.
  #
  #     **Non-Boot Disk**:
  #     If the `type` specifies a persistent disk, this field
  #     is ignored if `data_source` is set as `image` or `snapshot`.
  #     If the `type` specifies a local SSD, this field should be a multiple of
  #     375 GB, otherwise, the final size will be the next greater multiple of
  #     375 GB.
  #
  #     **Boot Disk**:
  #     Batch will calculate the boot disk size based on source
  #     image and task requirements if you do not speicify the size.
  #     If both this field and the `boot_disk_mib` field in task spec's
  #     `compute_resource` are defined, Batch will only honor this field.
  #     Also, this field should be no smaller than the source disk's
  #     size when the `data_source` is set as `snapshot` or `image`.
  #     For example, if you set an image as the `data_source` field and the
  #     image's default disk size 30 GB, you can only use this field to make the
  #     disk larger or equal to 30 GB.
  # @!attribute [rw] disk_interface
  #   @return [::String]
  #     Local SSDs are available through both "SCSI" and "NVMe" interfaces.
  #     If not indicated, "NVMe" will be the default one for local ssds.
  #     This field is ignored for persistent disks as the interface is chosen
  #     automatically. See
  #     https://cloud.google.com/compute/docs/disks/persistent-disks#choose_an_interface.
