DescribeSpotInstanceRequests

PDF

Describes the specified Spot Instance requests.

You can use DescribeSpotInstanceRequests to find a running Spot Instance by examining the response. If the status of the Spot Instance is fulfilled, the instance ID appears in the response and contains the identifier of the instance. Alternatively, you can use DescribeInstances with a filter to look for instances where the instance lifecycle is spot.

We recommend that you set MaxResults to a value between 5 and 1000 to limit the number of items returned. This paginates the output, which makes the list more manageable and returns the items faster. If the list of items exceeds your MaxResults value, then that number of items is returned along with a NextToken value that can be passed to a subsequent DescribeSpotInstanceRequests request to retrieve the remaining items.

Spot Instance requests are deleted four hours after they are canceled and their instances are terminated.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

Filter.N

The filters.

  • availability-zone-group - The Availability Zone group.

  • create-time - The time stamp when the Spot Instance request was created.

  • status-code - The short code describing the most recent evaluation of your Spot Instance request.

  • status-message - The message explaining the status of the Spot Instance request.

  • tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.

  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

SpotInstanceRequestId.N

The IDs of the Spot Instance requests.

Type: Array of strings

Required: No

Response Elements

The following elements are returned by the service.

Type: String

spotInstanceRequestSet

The Spot Instance requests.

Type: Array of SpotInstanceRequest objects

Errors

For information about the errors that are common to all actions, see Common client error codes.

Examples

Example for DescribeSpotInstanceRequests

This example returns information about current Spot Instance requests. In the response, if the status of the Spot Instance is fulfilled, the instance ID appears in the response and contains the identifier of the instance.
