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://www.googleapis.com/compute/beta/projects/{project}/zones/{zone}/instances/{resourceId}/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.
`resourceId`	`string` The instance name for this request.

project

string

Project ID for this request.

zone

string

The name of the zone for this request.

resourceId

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 disk even if it's currently attached to another instance.

Fields
`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.
`source`	`string` Specifies a valid partial or full URL to an existing Persistent Disk resource. When creating a new instance, one of `initializeParams.sourceImage` or `disks.source` is required except for local SSD. 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, not the URL for the disk. Authorization requires one or more of the following Google 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`	`number` [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 the disk with the instance name exists already in the given zone/region, a new name will be automatically generated.
`initializeParams.sourceImage`	`string` The source image to create this disk. When creating a new instance, one of `initializeParams.sourceImage` or `disks.source` is required except for local SSD. 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 Google 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. If not specified, the disk will be the same size as the image (usually 10GB). If specified, the size must be equal to or larger than 10GB.
`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` Other values include `pd-ssd` and `local-ssd`. If you define this field, you can provide either the full or partial URL. For example, the following are valid values: `https://www.googleapis.com/compute/v1/projects/project/zones/zone/diskTypes/diskType` `projects/project/zones/zone/diskTypes/diskType` `zones/zone/diskTypes/diskType` Note that for InstanceTemplate, this is the name of the disk type, not URL.
`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. Instance templates 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.
`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. 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. After being wrapped, the key must be encoded in RFC 4648 base64 encoding. Gets the RSA public key certificate provided by Google at: https://cloud-certs.storage.googleapis.com/google-cloud-csek-ingress.pem
`initializeParams.sourceImageEncryptionKey.kmsKeyName`	`string` The name of the encryption key that is stored in Google Cloud KMS.
`initializeParams.sourceImageEncryptionKey.sha256`	`string` [Output only] The RFC 4648 base64 encoded SHA-256 hash of the customer-supplied encryption key that protects this resource.
`initializeParams.labels`	`map (key: string, value: string)` Labels to apply to this disk. These can be later modified by the `disks.setLabels` method. This field is only applicable for persistent disks. An object containing a list of `"key": value` pairs. Example: `{ "name": "wrench", "mass": "1.3kg", "count": "3" }`.
`initializeParams.sourceSnapshot`	`string` The source snapshot to create this disk. When creating a new instance, one of `initializeParams.sourceSnapshot` or `disks.source` is required except for local SSD. 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.
`initializeParams.sourceSnapshotEncryptionKey.rsaEncryptedKey`	`string` Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource. 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. After being wrapped, the key must be encoded in RFC 4648 base64 encoding. Gets the RSA public key certificate provided by Google at: https://cloud-certs.storage.googleapis.com/google-cloud-csek-ingress.pem
`initializeParams.sourceSnapshotEncryptionKey.kmsKeyName`	`string` The name of the encryption key that is stored in Google Cloud KMS.
`initializeParams.sourceSnapshotEncryptionKey.sha256`	`string` [Output only] The RFC 4648 base64 encoded SHA-256 hash of the customer-supplied encryption key that protects this resource.
`initializeParams.description`	`string` An optional description. Provide this property when creating the disk.
`initializeParams.guestOsFeatures[]`	`object` A list of features to enable on the guest operating system. Applicable only for bootable images. Read Enabling guest operating system features to see a list of available options. Guest OS features are applied by merging `initializeParams.guestOsFeatures` and `disks.guestOsFeatures`
`initializeParams.guestOsFeatures[].type`	`enum` The ID of a supported feature. Read Enabling guest operating system features to see a list of available options.
`initializeParams.resourcePolicies[]`	`string` Resource policies applied to this disk for automatic snapshot creations. Specified using the full or partial URL. For instance template, specify only the resource policy name.
`autoDelete`	`boolean` Specifies whether the disk will be auto-deleted when the instance is deleted (but not when the disk is detached from the instance).
`licenses[]`	`string` [Output Only] Any valid publicly visible licenses.
`interface`	`enum` Specifies the disk interface to use for attaching this disk, which is either `SCSI` or `NVME`. The default is `SCSI`. Persistent disks must always use SCSI and the request will fail if you attempt to attach a persistent disk in any other format than SCSI. Local SSDs can use either NVME or SCSI. For performance characteristics of SCSI over NVMe, see Local SSD performance.
`guestOsFeatures[]`	`object` A list of features to enable on the guest operating system. Applicable only for bootable images. Read Enabling guest operating system features to see a list of available options.
`guestOsFeatures[].type`	`enum` The ID of a supported feature. Read Enabling guest operating system features to see a list of available options.
`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. Instance templates do not store customer-supplied encryption keys, so you cannot use your own keys to encrypt disks in a managed instance group.
`diskEncryptionKey.rawKey`	`string` Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.
`diskEncryptionKey.rsaEncryptedKey`	`string` Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource. 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. After being wrapped, the key must be encoded in RFC 4648 base64 encoding. Gets the RSA public key certificate provided by Google at: https://cloud-certs.storage.googleapis.com/google-cloud-csek-ingress.pem
`diskEncryptionKey.kmsKeyName`	`string` The name of the encryption key that is stored in Google Cloud KMS.
`diskEncryptionKey.sha256`	`string` [Output only] The RFC 4648 base64 encoded SHA-256 hash of the customer-supplied encryption key that protects this resource.
`kind`	`string` [Output Only] Type of the resource. Always `compute#attachedDisk` for attached disks.
