Request Syntax

response = client.describe_fast_launch_images(
            'Name': 'string',
            'Values': [
  • ImageIds (list) –

    Details for one or more Windows AMI image IDs.

    • (string) –

  • Filters (list) –

    Use the following filters to streamline results.

    • resource-type - The resource type for pre-provisioning.

    • launch-template - The launch template that is associated with the pre-provisioned Windows AMI.

    • owner-id - The owner ID for the pre-provisioning resource.

    • state - The current state of fast launching for the Windows AMI.

    • (dict) –

      A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

      If you specify multiple filters, the filters are joined with an AND, and the request returns only results that match all of the specified filters.

      • Name (string) –

        The name of the filter. Filter names are case-sensitive.

      • Values (list) –

        The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.

        • (string) –

  • MaxResults (integer) – The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.

  • NextToken (string) – The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.

  • DryRun (boolean) – 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.

Response Structure

  • (dict) –

    • FastLaunchImages (list) –

      A collection of details about the fast-launch enabled Windows images that meet the requested criteria.

      • (dict) –

        Describe details about a fast-launch enabled Windows image that meets the requested criteria. Criteria are defined by the DescribeFastLaunchImages action filters.

        • ImageId (string) –

          The image ID that identifies the fast-launch enabled Windows image.

        • ResourceType (string) –

          The resource type that is used for pre-provisioning the Windows AMI. Supported values include: snapshot.

        • SnapshotConfiguration (dict) –

          • TargetResourceCount (integer) –

            The number of pre-provisioned snapshots requested to keep on hand for a fast-launch enabled Windows AMI.

        • LaunchTemplate (dict) –

          The launch template that the fast-launch enabled Windows AMI uses when it launches Windows instances from pre-provisioned snapshots.

          • LaunchTemplateId (string) –

            The ID of the launch template for faster launching of the associated Windows AMI.
