Description

Creates a Spot Fleet request. The Spot Fleet request specifies the total target capacity and the On-Demand target capacity. Amazon EC2 calculates the difference between the total capacity and On-Demand capacity, and launches the difference as Spot capacity. You can submit a single request that includes multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet. By default, the Spot Fleet requests Spot Instances in the Spot Instance pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload. Alternatively, you can specify that the Spot Fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot Instances in your Spot Fleet are in different Spot pools, you can improve the availability of your fleet. You can specify tags for the Spot Fleet request and instances launched by the fleet. You cannot tag other resource types in a Spot Fleet request because only the spot-fleet-request and instance resource types are supported. For more information, see Spot Fleet requests in the Amazon EC2 User Guide. We strongly discourage using the RequestSpotFleet API because it is a legacy API with no planned investment. For options for requesting Spot Instances, see Which is the best Spot request method to use? in the Amazon EC2 User Guide.

Parameters

-CapacityRebalance_ReplacementStrategy <ReplacementStrategy>
The replacement strategy to use. Only available for fleets of type maintain.launch - Spot Fleet launches a new replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet. Spot 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 - Spot Fleet launches a new 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 (in TerminationDelay), terminates the instances that received a rebalance notification.

-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the SpotFleetRequestConfig_SpotPrice parameter. The -PassThru parameter is deprecated, use -Select '^SpotFleetRequestConfig_SpotPrice' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.RequestSpotFleetResponse). Specifying the name of a property of type Amazon.EC2.Model.RequestSpotFleetResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False

-SpotFleetRequestConfig_AllocationStrategy <AllocationStrategy>
The strategy that determines how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the Spot Fleet launch configuration. For more information, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide.
priceCapacityOptimized (recommended)
Spot 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. Spot Fleet then requests Spot Instances from the lowest priced of these pools.
capacityOptimized
Spot 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 capacityOptimizedPrioritized. 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. capacityOptimizedPrioritized is supported only if your Spot Fleet uses a launch template. Note that if the OnDemandAllocationStrategy is set to prioritized, the same priority is applied when fulfilling On-Demand capacity.
diversified
Spot Fleet requests instances from all of the Spot Instance pools that you specify.
lowestPrice
Spot 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, Spot 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.

-SpotFleetRequestConfig_IamFleetRole <String>
The Amazon Resource Name (ARN) of an Identity and Access Management (IAM) role that grants the Spot Fleet the permission to request, launch, terminate, and tag instances on your behalf. For more information, see Spot Fleet prerequisites in the Amazon EC2 User Guide. Spot Fleet can terminate Spot Instances on your behalf when you cancel its Spot Fleet request using CancelSpotFleetRequests or when the Spot Fleet request expires, if you set TerminateInstancesWithExpiration.

-SpotFleetRequestConfig_InstancePoolsToUseCount <Int32>
The number of Spot pools across which to allocate your target Spot capacity. Valid only when Spot AllocationStrategy is set to lowest-price. Spot Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify.Note that Spot 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, Spot 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.
Required?False

The order of the launch template overrides to use in fulfilling On-Demand capacity. If you specify lowestPrice, Spot Fleet uses price to determine the order, launching the lowest price first.

If you set a maximum price per hour for the On-Demand Instances and Spot Instances in your request, Spot Fleet will launch instances until it reaches the maximum amount you're willing to pay. When the maximum amount you're willing to pay is reached, the fleet stops launching instances even if it hasn’t met the target capacity.

-SpotFleetRequestConfig_Type <FleetType>
The type of request. Indicates whether the Spot Fleet only requests the target capacity or also attempts to maintain it. When this value is request, the Spot Fleet only places the required requests. It does not attempt to replenish Spot Instances if capacity is diminished, nor does it submit requests in alternative Spot pools if capacity is not available. When this value is maintain, the Spot Fleet maintains the target capacity. The Spot Fleet places the required requests to meet capacity and automatically replenishes any interrupted instances.

This example creates a Spot fleet request in the Availability Zone with the lowest price for the specified instance type. If your account supports EC2-VPC only, the Spot fleet launches the instances in the lowest-priced Availability Zone that has a default subnet. If your account supports EC2-Classic, the Spot fleet launches the instances in EC2-Classic in the lowest-priced Availability Zone. Note that the price you pay will not exceed the specified Spot price for the request.
