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/beta/projects/{project}/zones/{zone}/instances/{instance}

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.
instance

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.

[Output Only] Type of the resource. Always compute#instance for instances.
id

string (uint64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.
creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.
name

string

The name of the resource, provided by the client when initially creating the resource. The resource name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
description

string

An optional description of this resource. Provide this property when you create the resource.
tags

object

Tags to apply to this instance. Tags are used to identify valid sources or targets for network firewalls and are specified by the client during instance creation. The tags can be later modified by the setTags method. Each tag within the list must comply with RFC1035. Multiple tags can be specified via the 'tags.items' field.

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

  • compute.instances.setTags
tags.items[]

string

An array of tags. Each tag must be 1-63 characters long, and comply with RFC1035.
tags.fingerprint

string (bytes format)

Specifies a fingerprint for this request, which is essentially a hash of the tags' contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update tags. You must always provide an up-to-date fingerprint hash in order to update or change tags.

To see the latest fingerprint, make get() request to the instance.

A base64-encoded string.
machineType

string

Full or partial URL of the machine type resource to use for this instance, in the format: zones/zone/machineTypes/machine-type. This is provided by the client when the instance is created. For example, the following is a valid partial url to a predefined machine type:

zones/us-central1-f/machineTypes/n1-standard-1

To create a custom machine type, provide a URL to a machine type in the following format, where CPUS is 1 or an even number up to 32 (2, 4, 6, ... 24, etc), and MEMORY is the total memory for this instance. Memory must be a multiple of 256 MB and must be supplied in MB (e.g. 5 GB of memory is 5120 MB):

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:
