Method: instances.setScheduling

Sets an instance's scheduling options. You can only call this method on a stopped instance, that is, a VM instance that is in a TERMINATED state. See Instance Life Cycle for more information on the possible instance states. For more information about setting scheduling options for a VM, see Set VM host maintenance policy.

HTTP request

POST https://compute.googleapis.com/compute/beta/projects/{project}/zones/{zone}/instances/{instance}/setScheduling

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

Instance name 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).

boolean

Specifies whether the instance should be automatically restarted if it is terminated by Compute Engine (not terminated by a user). You can only set the automatic restart option for standard instances. Preemptible instances cannot be automatically restarted.

By default, this is set to true so an instance is automatically restarted if it is terminated by Compute Engine.

preemptible

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:

error.errors[].message

string

[Output Only] An optional, human-readable error message.

error.errors[].errorDetails[]

object

[Output Only] An optional list of messages that contain the error details. There is a set of defined message types to use for providing details.The syntax depends on the error code. For example, QuotaExceededInfo will have details when the error code is QUOTA_EXCEEDED.
