Attaches an existing Disk resource to an instance. You must first create the disk before you can attach it. It is not possible to create and attach a disk at the same time. For more information, read Adding a persistent disk to your instance.

HTTP request

POST https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/instances/{instance}/attachDisk

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.
`zone`	`string` The name of the zone for this request.
`instance`	`string` The instance name for this request.

project

string

Project ID for this request.

zone

string

The name of the zone for this request.

instance

string

The instance name for this request.

Query parameters

Parameters

Parameters
`requestId`	`string` An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported (`00000000-0000-0000-0000-000000000000`).
`forceAttach`	`boolean` Whether to force attach the regional disk even if it's currently attached to another instance. If you try to force attach a zonal disk to an instance, you will receive an error.

Fields
`kind`	`string` [Output Only] Type of the resource. Always `compute#attachedDisk` for attached disks.
`type`	`enum` Specifies the type of the disk, either `SCRATCH` or `PERSISTENT`. If not specified, the default is `PERSISTENT`.
`mode`	`enum` The mode in which to attach this disk, either `READ_WRITE` or `READ_ONLY`. If not specified, the default is to attach the disk in `READ_WRITE` mode.
`savedState`	`enum` For LocalSSD disks on VM Instances in STOPPED or SUSPENDED state, this field is set to `PRESERVED` if the LocalSSD data has been saved to a persistent location by customer request. (see the discardLocalSsd option on instances.stop/instances.suspend). Read-only in the api.
`source`	`string` Specifies a valid partial or full URL to an existing Persistent Disk resource. When creating a new instance boot disk, one of `initializeParams.sourceImage` or `initializeParams.sourceSnapshot` or `disks.source` is required. If desired, you can also attach existing non-root persistent disks using this property. This field is only applicable for persistent disks. Note that for InstanceTemplate, specify the disk name for zonal disk, and the URL for regional disk. Authorization requires one or more of the following IAM permissions on the specified resource `source`: `compute.disks.use` `compute.disks.useReadOnly`
`deviceName`	`string` Specifies a unique device name of your choice that is reflected into the `/dev/disk/by-id/google-*` tree of a Linux operating system running within the instance. This name can be used to reference the device for mounting, resizing, and so on, from within the instance. If not specified, the server chooses a default device name to apply to this disk, in the form `persistent-disk-x`, where x is a number assigned by Google Compute Engine. This field is only applicable for persistent disks.
`index`	`integer` [Output Only] A zero-based index to this disk, where 0 is reserved for the boot disk. If you have many disks attached to an instance, each disk would have a unique index number.
`boot`	`boolean` Indicates that this is a boot disk. The virtual machine will use the first partition of the disk for its root filesystem.
`initializeParams`	`object` [Input Only] Specifies the parameters for a new disk that will be created alongside the new instance. Use initialization parameters to create boot disks or local SSDs attached to the new instance. This property is mutually exclusive with the `source` property; you can only define one or the other, but not both.
`initializeParams.diskName`	`string` Specifies the disk name. If not specified, the default is to use the name of the instance. If a disk with the same name already exists in the given region, the existing disk is attached to the new instance and the new disk is not created.
`initializeParams.sourceImage`	`string` The source image to create this disk. When creating a new instance boot disk, one of `initializeParams.sourceImage` or `initializeParams.sourceSnapshot` or `disks.source` is required. To create a disk with one of the public operating system images, specify the image by its family name. For example, specify `family/debian-9` to use the latest Debian 9 image: `projects/debian-cloud/global/images/family/debian-9` Alternatively, use a specific version of a public operating system image: `projects/debian-cloud/global/images/debian-9-stretch-vYYYYMMDD` To create a disk with a custom image that you created, specify the image name in the following format: `global/images/my-custom-image` You can also specify a custom image by its image family, which returns the latest version of the image in that family. Replace the image name with `family/family-name`: `global/images/family/my-image-family` If the source image is deleted later, this field will not be set. Authorization requires one or more of the following IAM permissions on the specified resource `sourceImage`: `compute.disks.create` `compute.images.useReadOnly`
`initializeParams.diskSizeGb`	`string (int64 format)` Specifies the size of the disk in base-2 GB. The size must be at least 10 GB. If you specify a `sourceImage`, which is required for boot disks, the default size is the size of the `sourceImage`. If you do not specify a `sourceImage`, the default disk size is 500 GB.
`initializeParams.diskType`	`string` Specifies the disk type to use to create the instance. If not specified, the default is `pd-standard`, specified using the full URL. For example: `https://www.googleapis.com/compute/v1/projects/project/zones/zone/diskTypes/pd-standard` For a full list of acceptable values, see Persistent disk types. If you specify this field when creating a VM, you can provide either the full or partial URL. For example, the following values are valid: `https://www.googleapis.com/compute/v1/projects/project/zones/zone/diskTypes/diskType` `projects/project/zones/zone/diskTypes/diskType` `zones/zone/diskTypes/diskType` If you specify this field when creating or updating an instance template or all-instances configuration, specify the type of the disk, not the URL. For example: `pd-standard`.
`initializeParams.sourceImageEncryptionKey`	`object` The customer-supplied encryption key of the source image. Required if the source image is protected by a customer-supplied encryption key. InstanceTemplate and InstancePropertiesPatch do not store customer-supplied encryption keys, so you cannot create disks for instances in a managed instance group if the source images are encrypted with your own keys.
`initializeParams.sourceImageEncryptionKey.rawKey`	`string` Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource. You can provide either the `rawKey` or the `rsaEncryptedKey`. For example: "rawKey": "SGVsbG8gZnJvbSBHb29nbGUgQ2xvdWQgUGxhdGZvcm0="
`initializeParams.sourceImageEncryptionKey.rsaEncryptedKey`	`string` Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource. You can provide either the `rawKey` or the `rsaEncryptedKey`. For example: "rsaEncryptedKey": "ieCx/NcW06PcT7Ep1X6LUTc/hLvUDYyzSZPPVCVPTVEohpeHASqC8uw5TzyO9U+Fka9JFH z0mBibXUInrC/jEk014kCK/NPjYgEMOyssZ4ZINPKxlUh2zn1bV+MCaTICrdmuSBTWlUUiFoD D6PYznLwh8ZNdaheCeZ8ewEXgFQ8V+sDroLaN3Xs3MDTXQEMMoNUXMCZEIpg9Vtp9x2oe==" The key must meet the following requirements before you can provide it to Compute Engine: The key is wrapped using a RSA public key certificate provided by Google.

`initializeParams.sourceImageEncryptionKey.kmsKeyName`	`string` The name of the encryption key that is stored in Google Cloud KMS. For example: "kmsKeyName": "projects/ `kms_project_id`/locations/ `region`/keyRings/ `key_region`/cryptoKeys/`key` The fully-qualifed key name may be returned for resource GET requests. For example: "kmsKeyName": "projects/ `kms_project_id`/locations/ `region`/keyRings/ `key_region`/cryptoKeys/`key` /cryptoKeyVersions/1

`initializeParams.sourceSnapshot`	`string` The source snapshot to create this disk. When creating a new instance boot disk, one of `initializeParams.sourceSnapshot` or `initializeParams.sourceImage` or `disks.source` is required. To create a disk with a snapshot that you created, specify the snapshot name in the following format: `global/snapshots/my-backup` If the source snapshot is deleted later, this field will not be set.
`initializeParams.sourceSnapshotEncryptionKey`	`object` The customer-supplied encryption key of the source snapshot.
`initializeParams.sourceSnapshotEncryptionKey.rawKey`	`string` Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.

`diskEncryptionKey`	`object` Encrypts or decrypts a disk using a customer-supplied encryption key. If you are creating a new disk, this field encrypts the new disk using an encryption key that you provide. If you are attaching an existing disk that is already encrypted, this field decrypts the disk using the customer-supplied encryption key. If you encrypt a disk using a customer-supplied key, you must provide the same key again when you attempt to use this resource at a later time. For example, you must provide the key when you create a snapshot or an image from the disk or when you attach the disk to a virtual machine instance. If you do not provide an encryption key, then the disk will be encrypted using an automatically generated key and you do not need to provide a key to use the disk later. Note: Instance templates do not store customer-supplied encryption keys, so you cannot use your own keys to encrypt disks in a managed instance group. You cannot create VMs that have disks with customer-supplied keys using the bulk insert method.

Response body

Represents an Operation resource.

Google Compute Engine has three Operation resources:

You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.

Operations can be global, regional or zonal.

For global operations, use the globalOperations resource.
For regional operations, use the regionOperations resource.
For zonal operations, use the zoneOperations resource.

For more information, read Global, Regional, and Zonal Resources.

Note that completed Operation resources have a limited retention period.

If successful, the response body contains data with the following structure:

Fields
`kind`	`string` [Output Only] Type of the resource. Always `compute#operation` for Operation resources.
`id`	`string (uint64 format)` [Output Only] The unique identifier for the operation. This identifier is defined by the server.
`creationTimestamp`	`string` [Deprecated] This field is deprecated.
`name`	`string` [Output Only] Name of the operation.
`zone`	`string` [Output Only] The URL of the zone where the operation resides. Only applicable when performing per-zone operations.
`clientOperationId`	`string` [Output Only] The value of `requestId` if you provided it in the request. Not present otherwise.
`operationType`	`string` [Output Only] The type of operation, such as `insert`, `update`, or `delete`, and so on.
`targetLink`	`string` [Output Only] The URL of the resource that the operation modifies. For operations related to creating a snapshot, this points to the disk that the snapshot was created from.
`targetId`	`string (uint64 format)` [Output Only] The unique target ID, which identifies a specific incarnation of the target resource.
`status`	`enum` [Output Only] The status of the operation, which can be one of the following: `PENDING`, `RUNNING`, or `DONE`.
`statusMessage`	`string` [Output Only] An optional textual description of the current status of the operation.
`user`	`string` [Output Only] User who requested the operation, for example: `[email protected]` or `alice_smith_identifier (global/workforcePools/example-com-us-employees)`.
`progress`	`integer` [Output Only] An optional progress indicator that ranges from 0 to 100. There is no requirement that this be linear or support any granularity of operations. This should not be used to guess when the operation will be complete. This number should monotonically increase as the operation progresses.
`insertTime`	`string` [Output Only] The time that this operation was requested. This value is in RFC3339 text format.
`startTime`	`string` [Output Only] The time that this operation was started by the server. This value is in RFC3339 text format.
`endTime`	`string` [Output Only] The time that this operation was completed. This value is in RFC3339 text format.
`error`	`object` [Output Only] If errors are generated during processing of the operation, this field will be populated.
`error.errors[]`	`object` [Output Only] The array of errors encountered while processing this operation.
`error.errors[].code`	`string` [Output Only] The error type identifier for this error.
`error.errors[].location`	`string` [Output Only] Indicates the field in the request that caused the error. This property is optional.
`error.errors[].message`	`string` [Output Only] An optional, human-readable error message.
`error.errors[].errorDetails[]`	`object` [Output Only] An optional list of messages that contain the error details. There is a set of defined message types to use for providing details.The syntax depends on the error code. For example, QuotaExceededInfo will have details when the error code is QUOTA_EXCEEDED.
`error.errors[].errorDetails[].errorInfo`	`object`
`error.errors[].errorDetails[].errorInfo.reason`	`string` The reason of the error. This is a constant value that identifies the proximate cause of the error. Error reasons are unique within a particular domain of errors. This should be at most 63 characters and match a regular expression of `[A-Z][A-Z0-9_]+[A-Z0-9]`, which represents UPPER_SNAKE_CASE.
`error.errors[].errorDetails[].errorInfo.domain`	`string` The logical grouping to which the "reason" belongs. The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com". If the error is generated by some common infrastructure, the error domain must be a globally unique value that identifies the infrastructure. For Google API infrastructure, the error domain is "googleapis.com".
`error.errors[].errorDetails[].errorInfo.metadatas`	`map (key: string, value: string)` Additional structured details about this error. Keys must match /[a-z][a-zA-Z0-9-_]+/ but should ideally be lowerCamelCase. Also they must be limited to 64 characters in length. When identifying the current value of an exceeded limit, the units should be contained in the key, not the value. For example, rather than {"instanceLimit": "100/request"}, should be returned as, {"instanceLimitPerRequest": "100"}, if the client exceeds the number of instances that can be created in a single (batch) request.
`error.errors[].errorDetails[].quotaInfo`	`object`
`error.errors[].errorDetails[].quotaInfo.metricName`	`string` The Compute Engine quota metric name.
`error.errors[].errorDetails[].quotaInfo.limitName`	`string` The name of the quota limit.
`error.errors[].errorDetails[].quotaInfo.dimensions`	`map (key: string, value: string)` The map holding related quota dimensions.
`error.errors[].errorDetails[].quotaInfo.limit`	`number` Current effective quota limit. The limit's unit depends on the quota type or metric.
`error.errors[].errorDetails[].quotaInfo.futureLimit`	`number` Future quota limit being rolled out. The limit's unit depends on the quota type or metric.
`error.errors[].errorDetails[].quotaInfo.rolloutStatus`	`enum` Rollout status of the future quota limit.
`error.errors[].errorDetails[].help`	`object`
`error.errors[].errorDetails[].help.links[]`	`object` URL(s) pointing to additional information on handling the current error.
`error.errors[].errorDetails[].help.links[].description`	`string` Describes what the link offers.
`error.errors[].errorDetails[].help.links[].url`	`string` The URL of the link.
`error.errors[].errorDetails[].localizedMessage`	`object`
`error.errors[].errorDetails[].localizedMessage.locale`	`string` The locale used following the specification defined at https://www.rfc-editor.org/rfc/bcp/bcp47.txt. Examples are: "en-US", "fr-CH", "es-MX"
`error.errors[].errorDetails[].localizedMessage.message`	`string` The localized error message in the above locale.
`warnings[]`	`object` [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
`warnings[].code`	`enum` [Output Only] A warning code, if applicable. For example, Compute Engine returns `NO_RESULTS_ON_PAGE` if there are no results in the response.
`warnings[].message`	`string` [Output Only] A human-readable description of the warning code.
`warnings[].data[]`	`object` [Output Only] Metadata about this warning in `key: value` format. For example: "data": [ { "key": "scope", "value": "zones/us-east1-d" }
`warnings[].data[].key`	`string` [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be `scope` and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
`warnings[].data[].value`	`string` [Output Only] A warning data value corresponding to the key.
`httpErrorStatusCode`	`integer` [Output Only] If the operation fails, this field contains the HTTP error status code that was returned. For example, a `404` means the resource was not found.
`httpErrorMessage`	`string` [Output Only] If the operation fails, this field contains the HTTP error message that was returned, such as `NOT FOUND`.
`selfLink`	`string` [Output Only] Server-defined URL for the resource.
`region`	`string` [Output Only] The URL of the region where the operation resides. Only applicable when performing regional operations.
`description`	`string` [Output Only] A textual description of the operation, which is set when the operation is created.
