Constructor Details

#initialize(capacity_reservation_preference: nil, capacity_reservation_resource_group_arn: nil, usage_strategy: nil) ⇒ OnDemandCapacityReservationOptionsProperty

Returns a new instance of OnDemandCapacityReservationOptionsProperty.

Parameters:

  • capacity_reservation_preference (String, nil) (defaults to: nil) —

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

  • capacity_reservation_resource_group_arn (String, nil) (defaults to: nil) —

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

  • usage_strategy (String, nil) (defaults to: nil) —

    Indicates whether to use unused Capacity Reservations for fulfilling On-Demand capacity.

Instance Attribute Details

#capacity_reservation_preference ⇒ String? (readonly)

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, nil)

#capacity_reservation_resource_group_arn ⇒ String? (readonly)

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

Returns:

  • (String, nil)

end

#usage_strategy ⇒ String? (readonly)

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, nil)
