Instance Attribute Details
#capacity_reservation_preference ⇒ String
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.

#usage_strategy ⇒ String
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.
