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.

Returns:

  • (String)

end

#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.

Returns:

  • (String)
