description

string

Description of the disk.
The length must be less than or equal to 256.

labels

object (map<string, string>)

Resource labels as key:value pairs.
Each map key must match the regular expression: [a-z][-_./\\@0-9a-z]*.
Each map value must match the regular expression: [-_./\\@0-9a-z]*.
The length of each map key must be between 1 and 63.
The length of each map value must be less than or equal to 63.
The number of elements must be less than or equal to 64.

typeId

string

ID of the disk type.
To get a list of available disk types use the yandex.cloud.compute.v1.DiskTypeService.List request.
The length must be less than or equal to 50.

zoneId

string

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.
The length must be less than or equal to 50.
This field is required.

size

string (int64)

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.minDiskSize value.
The value must be between 4194304 and 28587302322176.
This field is required.

blockSize

string (int64)

Block size used for disk, specified in bytes. The default is 4096.

imageId

string

ID of the image to create the disk from.
The length must be less than or equal to 50.

Includes only one of the fields imageId, snapshotId.

snapshotId

string

ID of the snapshot to restore the disk from.
The length must be less than or equal to 50.

Includes only one of the fields imageId, snapshotId.

diskPlacementPolicy

DiskPlacementPolicy

Placement policy configuration.

snapshotScheduleIds[]

string

List of IDs of the snapshot schedules to attach the disk to.

hardwareGeneration

HardwareGeneration

Specify the overrides to hardware_generation of a source disk, image or snapshot,
or to the default values if the source does not define it.

kmsKeyId

string

ID of KMS key for disk encryption.
The length must be less than or equal to 50.

DiskPlacementPolicy

Field

Description

placementGroupId

string

Placement group ID.

placementGroupPartition

string (int64)

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

legacyFeatures

LegacyHardwareFeatures

Includes only one of the fields legacyFeatures, generation2Features.

generation2Features

object

Includes only one of the fields legacyFeatures, generation2Features.

LegacyHardwareFeatures

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

Field

Description

pciTopology

enum (PCITopology)

  • PCI_TOPOLOGY_V1
  • PCI_TOPOLOGY_V2

Response

HTTP Code: 200 - OK

}

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.

createdAt

string (date-time)

Creation timestamp.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

createdBy

string

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

modifiedAt

string (date-time)

The time when the Operation resource was last modified.

String in RFC3339 text format. The range of possible values is from
0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z, i.e. from 0 to 9 digits for fractions of a second.

To work with values in this field, use the APIs described in the
Protocol Buffers reference.
In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).

done

boolean

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

object

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

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

object

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.

Status

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

Field

Description

code
