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.
import { mixins as ec2_mixins } from '@aws-cdk/mixins-preview/aws-ec2';
const capacityReservationOptionsRequestProperty: ec2_mixins.CfnEC2FleetPropsMixin.CapacityReservationOptionsRequestProperty = {
usageStrategy: 'usageStrategy',

usageStrategy?
Type:
string
(optional)
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.
