Method: instances.update

Updates an instance only if the necessary resources are available. This method can update only a specific set of instance properties. See Updating a running instance for a list of updatable instance properties.

HTTP request

PUT https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/instances/{resourceId}

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

zone

string

The name of the zone for this request.

resourceId

string

Name of the instance resource to update.

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).

mostDisruptiveAllowedAction

enum

Specifies the most disruptive action that can be taken on the instance as part of the update. Compute Engine returns an error if the instance properties require a more disruptive action as part of the instance update. Valid options from lowest to highest are NO_EFFECT, REFRESH, and RESTART.

minimalAction

enum

Specifies the action to take when updating an instance even if the updated properties do not require it. If not specified, then Compute Engine acts based on the minimum action that the updated properties require.

For a full list of acceptable values, see Persistent disk types. If you define this field, you can provide either the full or partial URL. For example, the following are valid values:

Note that for InstanceTemplate, this is the name of the disk type, not URL.

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.

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.

disks[].initializeParams.sourceImageEncryptionKey.rsaEncryptedKey

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

Authorization requires the following IAM permission on the specified resource labels:

  • compute.disks.setLabels
disks[].initializeParams.sourceSnapshot

string

The source snapshot to create this disk. When creating a new instance, one of initializeParams.sourceSnapshot or initializeParams.sourceImage 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.

Authorization requires the following IAM permission on the specified resource sourceSnapshot:
