DryRunOperation . Otherwise, it is UnauthorizedOperation .Describes the configuration of Spot Instances in an EC2 Fleet.
The strategy that determines how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet launch configuration. For more information, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide .
price-capacity-optimized (recommended)
EC2 Fleet identifies the pools with the highest capacity availability for the number of instances that are launching. This means that we will request Spot Instances from the pools that we believe have the lowest chance of interruption in the near term. EC2 Fleet then requests Spot Instances from the lowest priced of these pools.
capacity-optimized
EC2 Fleet identifies the pools with the highest capacity availability for the number of instances that are launching. This means that we will request Spot Instances from the pools that we believe have the lowest chance of interruption in the near term. To give certain instance types a higher chance of launching first, use capacity-optimized-prioritized . Set a priority for each instance type by using the Priority parameter for LaunchTemplateOverrides . You can assign the same priority to different LaunchTemplateOverrides . EC2 implements the priorities on a best-effort basis, but optimizes for capacity first. capacity-optimized-prioritized is supported only if your EC2 Fleet uses a launch template. Note that if the On-Demand AllocationStrategy is set to prioritized , the same priority is applied when fulfilling On-Demand capacity.
diversified
EC2 Fleet requests instances from all of the Spot Instance pools that you specify.
lowest-price
EC2 Fleet requests instances from the lowest priced Spot Instance pool that has available capacity. If the lowest priced pool doesn't have available capacity, the Spot Instances come from the next lowest priced pool that has available capacity. If a pool runs out of capacity before fulfilling your desired capacity, EC2 Fleet will continue to fulfill your request by drawing from the next lowest priced pool. To ensure that your desired capacity is met, you might receive Spot Instances from several pools. Because this strategy only considers instance price and not capacity availability, it might lead to high interruption rates.
Default: lowest-price
The strategies for managing your Spot Instances that are at an elevated risk of being interrupted.
The strategy to use when Amazon EC2 emits a signal that your Spot Instance is at an elevated risk of being interrupted.
The replacement strategy to use. Only available for fleets of type maintain .
launch- EC2 Fleet launches a replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet. EC2 Fleet does not terminate the instances that receive a rebalance notification. You can terminate the old instances, or you can leave them running. You are charged for all instances while they are running.
launch-before-terminate- EC2 Fleet launches a replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet, and then, after a delay that you specify (inTerminationDelay), terminates the instances that received a rebalance notification.
The amount of time (in seconds) that Amazon EC2 waits before terminating the old Spot Instance after launching a new replacement Spot Instance.
Required when ReplacementStrategy is set to launch-before-terminate .
Not valid when ReplacementStrategy is set to launch .
Valid values: Minimum value of 120 seconds. Maximum value of 7200 seconds.
The behavior when a Spot Instance is interrupted.
Default: terminate
The number of Spot pools across which to allocate your target Spot capacity. Supported only when Spot AllocationStrategy is set to lowest-price . EC2 Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify.
Note that EC2 Fleet attempts to draw Spot Instances from the number of pools that you specify on a best effort basis. If a pool runs out of Spot capacity before fulfilling your target capacity, EC2 Fleet will continue to fulfill your request by drawing from the next cheapest pool. To ensure that your target capacity is met, you might receive Spot Instances from more than the number of pools that you specified. Similarly, if most of the pools have no Spot capacity, you might receive your full target capacity from fewer than the number of pools that you specified.
Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet.
Supported only for fleets of type instant .
Indicates that the fleet launches all Spot Instances into a single Availability Zone.
Supported only for fleets of type instant .
The minimum target capacity for Spot Instances in the fleet. If the minimum target capacity is not reached, the fleet launches no instances.
Supported only for fleets of type instant .
At least one of the following must be specified: SingleAvailabilityZone | SingleInstanceType
The maximum amount per hour for Spot Instances that you're willing to pay. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.
Warning
If you specify a maximum price, your Spot Instances will be interrupted more frequently than if you do not specify this parameter.
Describes the configuration of On-Demand Instances in an EC2 Fleet.
The strategy that determines the order of the launch template overrides to use in fulfilling On-Demand capacity.
lowest-price- EC2 Fleet uses price to determine the order, launching the lowest price first.
prioritized- EC2 Fleet uses the priority that you assigned to each launch template override, launching the highest priority first.
Default: lowest-price
The strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.
Supported only for fleets of type instant .
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 or prioritized ) 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 or prioritized ).
If you do not specify a value, the fleet fulfils the On-Demand capacity according to the chosen On-Demand allocation strategy.
Indicates that the fleet uses a single instance type to launch all On-Demand Instances in the fleet.
Supported only for fleets of type instant .

The instance type.
mac1.metalis not supported as a launch template override.
Note
If you specify InstanceType , you can't specify InstanceRequirements .
MaxPrice (string) --
The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.

WeightedCapacity (float) --
The number of units provided by the specified instance type.
Priority (float) --
The priority for the launch template override. The highest priority is launched first.
If the On-Demand AllocationStrategy is set to prioritized , EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.
If the Spot AllocationStrategy is set to capacity-optimized-prioritized , EC2 Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first.
Valid values are whole numbers starting at 0 . The lower the number, the higher the priority. If no number is set, the override has the lowest priority. You can set the same priority for different launch template overrides.
