REST Resource: machineTypes

Resource: MachineType

Represents a Machine Type resource.

You can use specific machine types for your VM instances based on performance and pricing requirements. For more information, readMachine Types.

Fields
kind

string

[Output Only] The type of the resource. Alwayscompute#machineType for machine types.

id

string (uint64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.

creationTimestamp

string

[Output Only] Creation timestamp inRFC3339 text format.

name

string

[Output Only] Name of the resource.

description

string

[Output Only] An optional textual description of the resource.

guestCpus

integer

[Output Only] The number of virtual CPUs that are available to the instance.

memoryMb

integer

[Output Only] The amount of physical memory available to the instance, defined in MB.

maximumPersistentDisks

integer

[Output Only] Maximum persistent disks allowed.

maximumPersistentDisksSizeGb

string (int64 format)

[Output Only] Maximum total persistent disks size (GB) allowed.

deprecated

object

[Output Only] The deprecation status associated with this machine type. Only applicable if the machine type is unavailable.

deprecated.state

enum

The deprecation state of this resource. This can beACTIVE,DEPRECATED,OBSOLETE, orDELETED. Operations which communicate the end of life date for an image, can useACTIVE. Operations which create a new resource using aDEPRECATED resource will return successfully, but with a warning indicating the deprecated resource and recommending its replacement. Operations which useOBSOLETE orDELETED resources will be rejected and result in an error.

deprecated.replacement

string

The URL of the suggested replacement for a deprecated resource. The suggested replacement resource must be the same kind of resource as the deprecated resource.

deprecated.deprecated

string

An optionalRFC3339 timestamp on or after which the state of this resource is intended to change toDEPRECATED. This is only informational and the status will not change unless the client explicitly changes it.

deprecated.obsolete

string

An optionalRFC3339 timestamp on or after which the state of this resource is intended to change toOBSOLETE. This is only informational and the status will not change unless the client explicitly changes it.

deprecated.deleted

string

An optionalRFC3339 timestamp on or after which the state of this resource is intended to change toDELETED. This is only informational and the status will not change unless the client explicitly changes it.

deprecated.stateOverride

object

The rollout policy for this deprecation. This policy is only enforced by image family views. The rollout policy restricts the zones where the associated resource is considered in a deprecated state. When the rollout policy does not include the user specified zone, or if the zone is rolled out, the associated resource is considered in a deprecated state.

The rollout policy for this deprecation is read-only, except for allowlisted users. This field might not be configured. To view the latest non-deprecated image in a specific zone, use theimageFamilyViews.get method.

deprecated.stateOverride.locationRolloutPolicies

map (key: string, value: string)

Location based rollout policies to apply to the resource.

Currently only zone names are supported and must be represented as valid URLs, like: zones/us-central1-a.

The value expects anRFC3339 timestamp on or after which the update is considered rolled out to the specified location.

deprecated.stateOverride.defaultRolloutTime

string

An optionalRFC3339 timestamp on or after which the update is considered rolled out to any zone that is not explicitly stated.

zone

string

[Output Only] The name of the zone where the machine type resides, such as us-central1-a.

selfLink

string

[Output Only] Server-defined URL for the resource.

isSharedCpu

boolean

[Output Only] Whether this machine type has a shared CPU. SeeShared-core machine types for more information.

accelerators[]

object

[Output Only] A list of accelerator configurations assigned to this machine type.

accelerators[].guestAcceleratorType

string

The accelerator type resource name, not a full URL, e.g.nvidia-tesla-t4.

accelerators[].guestAcceleratorCount

integer

Number of accelerator cards exposed to the guest.

architecture

enum

[Output Only] The architecture of the machine type.

bundledLocalSsds

object

[Output Only] The configuration of bundled local SSD for the machine type.

bundledLocalSsds.partitionCount

integer

The number of partitions.

bundledLocalSsds.defaultInterface

string

The default disk interface if the interface is not specified.

Methods

 Retrieves an aggregated list of machine types.

get

 Returns the specified machine type.

list
