Method: instanceTemplates.insert

Creates an instance template in the specified project using the data that is included in the request. If you are creating a new template to update an existing instance group, your new instance template must use the same network or, if applicable, the same subnetwork as the original template.

HTTP request

POST https://compute.googleapis.com/compute/beta/projects/{project}/global/instanceTemplates

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

Query 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).

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 the following IAM permission on the specified resource sourceImage:

  • compute.images.get
properties.disks[].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.

properties.disks[].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.
