Name of the disk.

description

string

Description of the disk.

labels

object (map<string, string>)

Required field. ID of the availability zone where the disk resides.
To get a list of available zones use the yandex.cloud.compute.v1.ZoneService.List request.

size

int64

Required field. Size of the disk, specified in bytes.
If the disk was created from a image, this value should be more than the
yandex.cloud.compute.v1.Image.min_disk_size value.

Includes only one of the fields image_id, snapshot_id.

snapshot_id

string

ID of the snapshot to restore the disk from.

Includes only one of the fields image_id, snapshot_id.

Description

placement_group_id

HardwareGeneration

A set of features, specific to a particular Compute hardware generation.
They are not necessary supported by every host OS or distro, thus they are fixed to an image
and are applied to all instances created with it as their boot disk image.
These features significantly determine how the instance is created, thus cannot be changed after the fact.

Field

Description

Includes only one of the fields legacy_features, generation2_features.

generation2_features

Generation2HardwareFeatures

Includes only one of the fields legacy_features, generation2_features.

A first hardware generation, by default compatible with all legacy images.
Allows switching to PCI_TOPOLOGY_V2 and back.

Field

Description

pci_topology

enum PCITopology

  • PCI_TOPOLOGY_UNSPECIFIED
  • PCI_TOPOLOGY_V1
  • PCI_TOPOLOGY_V2

Generation2HardwareFeatures

A second hardware generation, which by default assumes PCI_TOPOLOGY_V2
and UEFI boot (with UEFI related features).

Field

Description

Empty

}

An Operation resource. For more information, see Operation.

Field

Description

id

string

ID of the operation.

description

string

Description of the operation. 0-256 characters long.

created_at

google.protobuf.Timestamp

Creation timestamp.

created_by

string

ID of the user or service account who initiated the operation.

modified_at

google.protobuf.Timestamp

The time when the Operation resource was last modified.

done

bool

If the value is false, it means the operation is still in progress.
If true, the operation is completed, and either error or response is available.

metadata

CreateDiskMetadata

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any.

error

google.rpc.Status

The error result of the operation in case of failure or cancellation.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

response

Disk

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is google.protobuf.Empty.
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

CreateDiskMetadata

Field

Description

string

ID of the disk that is being created.

Disk

A Disk resource. For more information, see Disks.

If you know the license IDs, specify them when you create the image.
For example, if you create a disk image using a third-party utility and load it into Object Storage, the license IDs will be lost.
You can specify them in the yandex.cloud.compute.v1.ImageService.Create request.
