modify_spot_fleet_request

EC2.Client.modify_spot_fleet_request(**kwargs)

Modifies the specified Spot Fleet request.

You can only modify a Spot Fleet request of type maintain.

While the Spot Fleet request is being modified, it is in the modifying state.

To scale up your Spot Fleet, increase its target capacity. The Spot Fleet launches the additional Spot Instances according to the allocation strategy for the Spot Fleet request. If the allocation strategy is lowestPrice, the Spot Fleet launches instances using the Spot Instance pool with the lowest price. If the allocation strategy is diversified, the Spot Fleet distributes the instances across the Spot Instance pools. If the allocation strategy is capacityOptimized, Spot Fleet launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching.

To scale down your Spot Fleet, decrease its target capacity. First, the Spot Fleet cancels any open requests that exceed the new target capacity. You can request that the Spot Fleet terminate Spot Instances until the size of the fleet no longer exceeds the new target capacity. If the allocation strategy is lowestPrice, the Spot Fleet terminates the instances with the highest price per unit. If the allocation strategy is capacityOptimized, the Spot Fleet terminates the instances in the Spot Instance pools that have the least available Spot Instance capacity. If the allocation strategy is diversified, the Spot Fleet terminates instances across the Spot Instance pools. Alternatively, you can request that the Spot Fleet keep the fleet at its current size, but not replace any Spot Instances that are interrupted or that you terminate manually.

If you are finished with your Spot Fleet for now, but will use it again later, you can set the target capacity to 0.

    SpotFleetRequestId='string',
    TargetCapacity=123,
    OnDemandTargetCapacity=123,
    Context='string'
)

Parameters:

• ExcessCapacityTerminationPolicy (string) –

  Indicates whether running instances should be terminated if the target capacity of the Spot Fleet request is decreased below the current size of the Spot Fleet.

  Supported only for fleets of type maintain.

• LaunchTemplateConfigs (list) –

  The launch template and overrides. You can only use this parameter if you specified a launch template ( LaunchTemplateConfigs) in your Spot Fleet request. If you specified LaunchSpecifications in your Spot Fleet request, then omit this parameter.

  • (dict) –

    Describes a launch template and overrides.

    • LaunchTemplateSpecification (dict) –

      The launch template to use. Make sure that the launch template does not contain the NetworkInterfaceId parameter because you can’t specify a network interface ID in a Spot Fleet.

      • LaunchTemplateId (string) –

        The ID of the launch template.

        You must specify the LaunchTemplateId or the LaunchTemplateName, but not both.

      • LaunchTemplateName (string) –

        The name of the launch template.

        You must specify the LaunchTemplateName or the LaunchTemplateId, but not both.

      • Version (string) –

        The launch template version number, $Latest, or $Default. You must specify a value, otherwise the request fails.

        If the value is $Latest, Amazon EC2 uses the latest version of the launch template.

        If the value is $Default, Amazon EC2 uses the default version of the launch template.

    • Overrides (list) –

      Any parameters that you specify override the same parameters in the launch template.

      • (dict) –

        Describes overrides for a launch template.

        • InstanceType (string) –

          The instance type.

        • SpotPrice (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.

          Warning

          If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.

        • SubnetId (string) –

          The ID of the subnet in which to launch the instances.

        • AvailabilityZone (string) –

          The Availability Zone in which to launch the instances.

        • 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 OnDemandAllocationStrategy is set to prioritized, Spot Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

          If the Spot AllocationStrategy is set to capacityOptimizedPrioritized, Spot 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 launch template override has the lowest priority. You can set the same priority for different launch template overrides.

        • InstanceRequirements (dict) –

          The instance requirements. When you specify instance requirements, Amazon EC2 will identify instance types with the provided requirements, and then use your On-Demand and Spot allocation strategies to launch instances from these instance types, in the same way as when you specify a list of instance types.

          Note

          If you specify InstanceRequirements, you can’t specify InstanceType.

          • VCpuCount (dict) –

            The minimum and maximum number of vCPUs.

            • (string) –

          • SpotMaxPricePercentageOverLowestPrice (integer) –

            The price protection threshold for Spot Instances. This is the maximum you’ll pay for a Spot Instance, expressed as a percentage above the least expensive current generation M, C, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it excludes instance types priced above your threshold.

            The parameter accepts an integer, which Amazon EC2 interprets as a percentage.

            To turn off price protection, specify a high value, such as 999999.

            This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements.

            Note

            If you set TargetCapacityUnitType to vcpu or memory-mib, the price protection threshold is applied based on the per-vCPU or per-memory price instead of the per-instance price.

            The price protection threshold for On-Demand Instances. This is the maximum you’ll pay for an On-Demand Instance, expressed as a percentage above the least expensive current generation M, C, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it excludes instance types priced above your threshold.

            The parameter accepts an integer, which Amazon EC2 interprets as a percentage.

            To turn off price protection, specify a high value, such as 999999.

            This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements.

            Note

            If you set TargetCapacityUnitType to vcpu or memory-mib, the price protection threshold is applied based on the per-vCPU or per-memory price instead of the per-instance price.

Response Syntax

{
    'Return': True|False
}

Response Structure

• (dict) –

  Contains the output of ModifySpotFleetRequest.

  • Return (boolean) –

    If the request succeeds, the response returns true. If the request fails, no response is returned, and instead an error message is returned.

Examples

This example increases the target capacity of the specified Spot fleet request.

response = client.modify_spot_fleet_request(
    SpotFleetRequestId='sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE',
    TargetCapacity=20,
)

print(response)

Expected Output:

{
    'Return': True,
    'ResponseMetadata': {
        '...': '...',
    },
}

This example decreases the target capacity of the specified Spot fleet request without terminating any Spot Instances as a result.

response = client.modify_spot_fleet_request(
    ExcessCapacityTerminationPolicy='NoTermination ',
    SpotFleetRequestId='sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE',
    TargetCapacity=10,
)

print(response)

Expected Output:

{
    'Return': True,
    'ResponseMetadata': {
        '...': '...',
    },
}
