Class Disk (0.17.15)

Disk(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A new persistent disk or a local ssd. A VM can only have one local SSD setting but multiple local SSD partitions. See and

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.

.. _oneof:


image str
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. This field is a member of oneof_ data_source.
snapshot str
Name of a snapshot used as the data source. Snapshot is not supported as boot disk now. This field is a member of oneof_ data_source.
type_ str
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".
size_gb int
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.
disk_interface str
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
