@Stability(Stable)
public static interface CfnEC2Fleet.CapacityReservationOptionsRequestProperty
extends software.amazon.jsii.JsiiSerializable

Describes the strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.

This strategy can only be used if the EC2 Fleet is of type instant .

For more information about Capacity Reservations, see On-Demand Capacity Reservations in the Amazon EC2 User Guide . For examples of using Capacity Reservations in an EC2 Fleet, see EC2 Fleet example configurations in the Amazon EC2 User Guide .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.

Method Details

getUsageStrategy

@Stability(Stable)
@Nullable
default String getUsageStrategy()

Indicates whether to use unused Capacity Reservations for fulfilling On-Demand capacity.

If you specify use-capacity-reservations-first , the fleet uses unused Capacity Reservations to fulfill On-Demand capacity up to the target On-Demand capacity. If multiple instance pools have unused Capacity Reservations, the On-Demand allocation strategy ( lowest-price or prioritized ) is applied. If the number of unused Capacity Reservations is less than the On-Demand target capacity, the remaining On-Demand target capacity is launched according to the On-Demand allocation strategy ( lowest-price or prioritized ).

If you do not specify a value, the fleet fulfils the On-Demand capacity according to the chosen On-Demand allocation strategy.
