Request Syntax

response = client.describe_capacity_reservation_fleets(
    CapacityReservationFleetIds=[
        'string',
    ],
    NextToken='string',
    MaxResults=123,
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    DryRun=True|False
)
Parameters:
  • CapacityReservationFleetIds (list) –

    The IDs of the Capacity Reservation Fleets to describe.

    • (string) –

  • NextToken (string) – The token to use to retrieve the next page of results.

  • MaxResults (integer) – The maximum number of results to return for the request in a single page. The remaining results can be seen by sending another request with the returned nextToken value. This value can be between 5 and 500. If maxResults is given a larger value than 500, you receive an error.

  • Filters (list) –

    One or more filters.

    • state - The state of the Fleet ( submitted | modifying | active | partially_fulfilled | expiring | expired | cancelling | cancelled | failed).

    • instance-match-criteria - The instance matching criteria for the Fleet. Only open is supported.

    • tenancy - The tenancy of the Fleet ( default | dedicated).

    • allocation-strategy - The allocation strategy used by the Fleet. Only prioritized is supported.

    • (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) –

  • 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.

Return type:

dict

Returns:

Response Structure

  • (dict) –

    • CapacityReservationFleets (list) –

      Information about the Capacity Reservation Fleets.

      • (dict) –

        Information about a Capacity Reservation Fleet.

        • CapacityReservationFleetId (string) –

          The ID of the Capacity Reservation Fleet.

        • CapacityReservationFleetArn (string) –

          The ARN of the Capacity Reservation Fleet.

        • State (string) –

          The state of the Capacity Reservation Fleet. Possible states include:

          • submitted - The Capacity Reservation Fleet request has been submitted and Amazon Elastic Compute Cloud is preparing to create the Capacity Reservations.

          • modifying - The Capacity Reservation Fleet is being modified. The Fleet remains in this state until the modification is complete.

          • active - The Capacity Reservation Fleet has fulfilled its total target capacity and it is attempting to maintain this capacity. The Fleet remains in this state until it is modified or deleted.

          • partially_fulfilled - The Capacity Reservation Fleet has partially fulfilled its total target capacity. There is insufficient Amazon EC2 to fulfill the total target capacity. The Fleet is attempting to asynchronously fulfill its total target capacity.

          • expiring - The Capacity Reservation Fleet has reach its end date and it is in the process of expiring. One or more of its Capacity reservations might still be active.

          • expired - The Capacity Reservation Fleet has reach its end date. The Fleet and its Capacity Reservations are expired. The Fleet can’t create new Capacity Reservations.

          • cancelling - The Capacity Reservation Fleet is in the process of being cancelled. One or more of its Capacity reservations might still be active.

          • cancelled - The Capacity Reservation Fleet has been manually cancelled. The Fleet and its Capacity Reservations are cancelled and the Fleet can’t create new Capacity Reservations.

          • failed - The Capacity Reservation Fleet failed to reserve capacity for the specified instance types.

        • TotalTargetCapacity (integer) –

          The total number of capacity units for which the Capacity Reservation Fleet reserves capacity. For more information, see Total target capacity in the Amazon EC2 User Guide.

        • TotalFulfilledCapacity (float) –

          The capacity units that have been fulfilled.

        • Tenancy (string) –

          The tenancy of the Capacity Reservation Fleet. Tenancies include:

          • default - The Capacity Reservation Fleet is created on hardware that is shared with other Amazon Web Services accounts.

          • dedicated - The Capacity Reservation Fleet is created on single-tenant hardware that is dedicated to a single Amazon Web Services account.

        • EndDate (datetime) –

          The date and time at which the Capacity Reservation Fleet expires.

        • CreateTime (datetime) –

          The date and time at which the Capacity Reservation Fleet was created.

        • InstanceMatchCriteria (string) –

          Indicates the type of instance launches that the Capacity Reservation Fleet accepts. All Capacity Reservations in the Fleet inherit this instance matching criteria.

          Currently, Capacity Reservation Fleets support open instance matching criteria only. This means that instances that have matching attributes (instance type, platform, and Availability Zone) run in the Capacity Reservations automatically. Instances do not need to explicitly target a Capacity Reservation Fleet to use its reserved capacity.

        • AllocationStrategy (string) –

          The strategy used by the Capacity Reservation Fleet to determine which of the specified instance types to use. For more information, see For more information, see Allocation strategy in the Amazon EC2 User Guide.

        • InstanceTypeSpecifications (list) –

          Information about the instance types for which to reserve the capacity.

          • (dict) –

            Information about a Capacity Reservation in a Capacity Reservation Fleet.

            • CapacityReservationId (string) –

              The ID of the Capacity Reservation.

            • AvailabilityZoneId (string) –

              The ID of the Availability Zone in which the Capacity Reservation reserves capacity.

            • InstanceType (string) –

              The instance type for which the Capacity Reservation reserves capacity.

            • InstancePlatform (string) –

              The type of operating system for which the Capacity Reservation reserves capacity.
