capacity_reservation_preference instance-attribute

capacity_reservation_preference: NotRequired[OnDemandCapacityReservationPreference]

Indicates the instance's Capacity Reservation preferences. Possible preferences include:

  • open - The instance can run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone).

  • none - The instance avoids running in a Capacity Reservation even if one is available. The instance runs as an On-Demand Instance.

capacity_reservation_resource_group_arn instance-attribute

capacity_reservation_resource_group_arn: NotRequired[XmlStringMaxLen256]

The ARN of the Capacity Reservation resource group in which to run the instance.

usage_strategy instance-attribute

usage_strategy: NotRequired[OnDemandCapacityReservationUsageStrategy]

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) 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).

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