AWS::EC2::EC2Fleet ReservedCapacityOptionsRequest
Defines EC2 Fleet preferences for utilizing reserved capacity when DefaultTargetCapacityType
is set to reserved-capacity. EC2 Fleet can fulfill reserved capacity using On-Demand Capacity Reservations,
Capacity Blocks for ML, and interruptible Capacity Reservations.
Note
This configuration can only be used if the EC2 Fleet is of type
instant.
When you specify ReservedCapacityOptions, you must also set
DefaultTargetCapacityType to reserved-capacity in the
TargetCapacitySpecification.
For more information about interruptible Capacity Reservations, see Launch instances into an interruptible Capacity Reservation in the Amazon EC2 User Guide.
Syntax
To declare this entity in your CloudFormation template, use the following syntax:
JSON
{ "AllocationStrategy" :String, "CapacityReservationTarget" :CapacityReservationTargetRequest, "ReservationTypes" :[ String, ... ], "ReservedCapacityFallbackOptions" :ReservedCapacityFallbackOptionsRequest}
YAML
AllocationStrategy:StringCapacityReservationTarget:CapacityReservationTargetRequestReservationTypes:- StringReservedCapacityFallbackOptions:ReservedCapacityFallbackOptionsRequest
Properties
AllocationStrategy-
The strategy that determines the order in which EC2 Fleet launches instances across the reservation types that you specify. The only supported value is
prioritized, which launches instances in the priority order that you specify in your launch template overrides. If you don't specify an allocation strategy, instances are launched in a random order.Required: No
Type: String
Allowed values:
prioritizedUpdate requires: Replacement
CapacityReservationTarget-
The Capacity Reservations or Capacity Reservation Resource Groups to use for fulfilling the EC2 Fleet request. You can specify Capacity Reservation IDs or a Capacity Reservation Resource Group ARN, but not both.
Required: No
Type: CapacityReservationTargetRequest
Update requires: Replacement
ReservationTypes-
The types of Capacity Reservations to use for fulfilling the EC2 Fleet request. This is an ordered list: EC2 Fleet attempts to launch instances into each Capacity Reservation type in the order that you specify them before moving on to the next type.
Required: No
Type: Array of String
Allowed values:
on-demand-capacity-reservation | capacity-block | interruptible-capacity-reservationUpdate requires: Replacement
ReservedCapacityFallbackOptions-
The fallback behavior for the EC2 Fleet when there is not enough reserved capacity available to meet the target capacity. This member takes a
ReservedCapacityFallbackOptionsRequeststructure, in which you setMarketTypesto the instance purchasing options to fall back to.Required: No
