public class CreateCapacityReservationFleetRequest : AmazonEC2Request

The CreateCapacityReservationFleetRequest type exposes the following members



Public Property AllocationStrategy System.String

Gets and sets the property AllocationStrategy.

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

Valid values: prioritized

Public Property ClientToken System.String

Gets and sets the property ClientToken.

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see Ensure Idempotency.

Public Property EndDate System.DateTime

Gets and sets the property EndDate.

The date and time at which the Capacity Reservation Fleet expires. When the Capacity Reservation Fleet expires, its state changes to expired and all of the Capacity Reservations in the Fleet expire.

The Capacity Reservation Fleet expires within an hour after the specified time. For example, if you specify 5/31/2019, 13:30:55, the Capacity Reservation Fleet is guaranteed to expire between 13:30:55 and 14:30:55 on 5/31/2019.

Public Property InstanceMatchCriteria Amazon.EC2.FleetInstanceMatchCriteria

Gets and sets the property InstanceMatchCriteria.

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.

Public Property InstanceTypeSpecifications System.Collections.Generic.List<Amazon.EC2.Model.ReservationFleetInstanceSpecification>

Gets and sets the property InstanceTypeSpecifications.

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

Public Property TagSpecifications System.Collections.Generic.List<Amazon.EC2.Model.TagSpecification>

Gets and sets the property TagSpecifications.

The tags to assign to the Capacity Reservation Fleet. The tags are automatically assigned to the Capacity Reservations in the Fleet.

Public Property Tenancy Amazon.EC2.FleetCapacityReservationTenancy

Gets and sets the property Tenancy.

Indicates the tenancy of the Capacity Reservation Fleet. All Capacity Reservations in the Fleet inherit this tenancy. The Capacity Reservation Fleet can have one of the following tenancy settings:

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

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

Public Property TotalTargetCapacity System.Int32

Gets and sets the property TotalTargetCapacity.

The total number of capacity units to be reserved by the Capacity Reservation Fleet. This value, together with the instance type weights that you assign to each instance type used by the Fleet determine the number of instances for which the Fleet reserves capacity. Both values are based on units that make sense for your workload. For more information, see Total target capacity in the Amazon EC2 User Guide.
