SpotFleetRequestConfigData
Describes the configuration of a Spot Fleet request.
Contents
- AllocationStrategy (request), allocationStrategy (response)
-
Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the Spot Fleet request.
If the allocation strategy is
lowestPrice
, Spot Fleet launches instances from the Spot Instance pools with the lowest price. This is the default allocation strategy.If the allocation strategy is
diversified
, Spot Fleet launches instances from all the Spot Instance pools that you specify.If the allocation strategy is
capacityOptimized
(recommended), Spot Fleet launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching. To give certain instance types a higher chance of launching first, usecapacityOptimizedPrioritized
. Set a priority for each instance type by using thePriority
parameter forLaunchTemplateOverrides
. You can assign the same priority to differentLaunchTemplateOverrides
. 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 theOnDemandAllocationStrategy
is set toprioritized
, the same priority is applied when fulfilling On-Demand capacity.Type: String
Valid Values:
lowestPrice | diversified | capacityOptimized | capacityOptimizedPrioritized
Required: No
- ClientToken (request), clientToken (response)
-
A unique, case-sensitive identifier that you provide to ensure the idempotency of your listings. This helps to avoid duplicate listings. For more information, see Ensuring Idempotency.
Type: String
Required: No
- ExcessCapacityTerminationPolicy (request), excessCapacityTerminationPolicy (response)

Indicates whether running Spot Instances should be terminated if you decrease the target capacity of the Spot Fleet request below the current size of the Spot Fleet.
Type: String
Valid Values:

- FulfilledCapacity (request), fulfilledCapacity (response)
-
The number of units fulfilled by this request compared to the set target capacity. You cannot set this value.

Required: No
- IamFleetRole (request), iamFleetRole (response)
-
The Amazon Resource Name (ARN) of an AWS 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 for Linux Instances. 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
.Type: String
Required: Yes
- InstanceInterruptionBehavior (request), instanceInterruptionBehavior (response)
-
The behavior when a Spot Instance is interrupted. The default is
terminate
.Type: String
Valid Values:
hibernate | stop | terminate
Required: No
- InstancePoolsToUseCount (request), instancePoolsToUseCount (response)
-
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.Type: Integer
Required: No
- LaunchSpecifications (request), launchSpecifications (response)
-
The launch specifications for the Spot Fleet request. If you specify
LaunchSpecifications
, you can't specifyLaunchTemplateConfigs
. If you include On-Demand capacity in your request, you must useLaunchTemplateConfigs
.Type: Array of SpotFleetLaunchSpecification objects
Required: No
- LaunchTemplateConfigs (request), launchTemplateConfigs (response)
-
The launch template and overrides. If you specify
LaunchTemplateConfigs
, you can't specifyLaunchSpecifications
. If you include On-Demand capacity in your request, you must useLaunchTemplateConfigs
.Type: Array of LaunchTemplateConfig objects
Required: No
- LoadBalancersConfig (request), loadBalancersConfig (response)
-
One or more Classic Load Balancers and target groups to attach to the Spot Fleet request. Spot Fleet registers the running Spot Instances with the specified Classic Load Balancers and target groups.
With Network Load Balancers, Spot Fleet cannot register instances that have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1.
Type: LoadBalancersConfig object
Required: No
- OnDemandAllocationStrategy (request), onDemandAllocationStrategy (response)
-
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 specifyprioritized
, Spot Fleet uses the priority that you assign to each Spot Fleet launch template override, launching the highest priority first. If you do not specify a value, Spot Fleet defaults tolowestPrice
.Type: String
Valid Values:
lowestPrice | prioritized
Required: No
- OnDemandFulfilledCapacity (request), onDemandFulfilledCapacity (response)
-
The number of On-Demand units fulfilled by this request compared to the set target On-Demand capacity.
Type: Double
Required: No
- OnDemandMaxTotalPrice (request), onDemandMaxTotalPrice (response)
-
The maximum amount per hour for On-Demand Instances that you're willing to pay. You can use the
onDemandMaxTotalPrice
parameter, thespotMaxTotalPrice
parameter, or both parameters to ensure that your fleet cost does not exceed your budget. 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.Type: String
Required: No
- OnDemandTargetCapacity (request), onDemandTargetCapacity (response)
-
The number of On-Demand units to request. You can choose to set the target capacity in terms of instances or a performance characteristic that is important to your application workload, such as vCPUs, memory, or I/O. If the request type is
maintain
, you can specify a target capacity of 0 and add capacity later.Type: Integer
Required: No

-
The maximum amount per hour for Spot Instances that you're willing to pay. You can use the
spotdMaxTotalPrice
parameter, theonDemandMaxTotalPrice
parameter, or both parameters to ensure that your fleet cost does not exceed your budget. 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.Type: String

The key-value pair for tagging the Spot Fleet request on creation. The value for
ResourceType
must bespot-fleet-request
, otherwise the Spot Fleet request fails. To tag instances at launch, specify the tags in the launch template (valid only if you useLaunchTemplateConfigs
) or in theSpotFleetTagSpecification
(valid only if you useLaunchSpecifications
). For information about tagging after launch, see Tagging Your Resources.Type: Array of TagSpecification objects
Required: No
- TargetCapacity (request), targetCapacity (response)
-
The number of units to request for the Spot Fleet. You can choose to set the target capacity in terms of instances or a performance characteristic that is important to your application workload, such as vCPUs, memory, or I/O. If the request type is

- TerminateInstancesWithExpiration (request), terminateInstancesWithExpiration (response)
-
Indicates whether running Spot Instances are terminated when the Spot Fleet request expires.
Type: Boolean
Required: No
- Type (request), type (response)
-
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 ismaintain
, the Spot Fleet maintains the target capacity. The Spot Fleet places the required requests to meet capacity and automatically replenishes any interrupted instances. Default:maintain
.instant
is listed but is not used by Spot Fleet.Type: String
Valid Values:
request | maintain | instant
Required: No
- ValidFrom (request), validFrom (response)
