class AWSEC2CapacityReservationOptions

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.

  • 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.
