The URL uses Google API HTTP annotation syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.

project

string

Project ID 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`).

`properties.networkInterfaces[].accessConfigs[].name`	`string` The name of this access configuration. The default and recommended name is `External NAT` but you can use any arbitrary string you would like. For example, `My external IP` or `Network Access`.
`properties.networkInterfaces[].accessConfigs[].natIP`	`string` An external IP address associated with this instance. Specify an unused static external IP address available to the project or leave this field undefined to use an IP from a shared ephemeral IP address pool. If you specify a static external IP address, it must live in the same region as the zone of the instance.
`properties.networkInterfaces[].accessConfigs[].setPublicPtr`	`boolean` Specifies whether a public DNS ‘PTR’ record should be created to map the external IP address of the instance to a DNS domain name.

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-8` to use the latest Debian 8 image: `projects/debian-cloud/global/images/family/debian-8` Alternatively, use a specific version of a public operating system image: `projects/debian-cloud/global/images/debian-8-jessie-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 Google IAM permission on the specified resource `source_image`: `compute.images.get`

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.
`properties.disks[].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.
`properties.disks[].initializeParams.sourceImageEncryptionKey.rawKey`	`string` Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.

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.
`properties.disks[].diskEncryptionKey.rawKey`	`string` Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.

`properties.metadata.items[]`	`object` Array of key/value pairs. The total size of all keys and values must be less than 512 KB.
`properties.metadata.items[].key`	`string` Key for the metadata entry. Keys must conform to the following regexp: `[a-zA-Z0-9-_]+`, and be less than 128 bytes in length. This is reflected as part of a URL in the metadata server. Additionally, to avoid ambiguity, keys must not conflict with any other metadata keys for the project.
`properties.metadata.items[].value`	`string` Value for the metadata entry. These are free-form strings, and only have meaning as interpreted by the image running in the instance. The only restriction placed on values is that their size must be less than or equal to 262144 bytes (256 KiB).
