Fields

usageStrategy :: Maybe 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.
capacityReservationResourceGroupArn :: Maybe Text
The ARN of the Capacity Reservation resource group in which to run the instance.
capacityReservationPreference :: Maybe 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.

newOnDemandCapacityReservationOptions :: OnDemandCapacityReservationOptions Source #

Create a value of OnDemandCapacityReservationOptions with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:usageStrategy:OnDemandCapacityReservationOptions', onDemandCapacityReservationOptions_usageStrategy - 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.

$sel:capacityReservationResourceGroupArn:OnDemandCapacityReservationOptions', onDemandCapacityReservationOptions_capacityReservationResourceGroupArn - The ARN of the Capacity Reservation resource group in which to run the instance.

$sel:capacityReservationPreference:OnDemandCapacityReservationOptions', onDemandCapacityReservationOptions_capacityReservationPreference - 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.

onDemandCapacityReservationOptions_usageStrategy :: Lens' OnDemandCapacityReservationOptions (Maybe OnDemandCapacityReservationUsageStrategy) Source #

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.

onDemandCapacityReservationOptions_capacityReservationResourceGroupArn :: Lens' OnDemandCapacityReservationOptions (Maybe Text) Source #

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

onDemandCapacityReservationOptions_capacityReservationPreference :: Lens' OnDemandCapacityReservationOptions (Maybe OnDemandCapacityReservationPreference) Source #

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.
