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.

Parameters:

• 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. These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O.

          If the target capacity divided by this value is not a whole number, Amazon EC2 rounds the number of instances to the next whole number. If this value is not specified, the default is 1.

          Note

          When specifying weights, the price used in the lowestPrice and priceCapacityOptimized allocation strategies is per unit hour (where the instance price is divided by the specified weight). However, if all the specified weights are above the requested TargetCapacity, resulting in only 1 instance being launched, the price used is per instance hour.

        • 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.

            • Min (integer) –

              The minimum number of vCPUs. If the value is 0, there is no minimum limit.

            • Max (integer) –

              The maximum number of vCPUs. If this parameter is not specified, there is no maximum limit.

            • Min (integer) –

              The minimum amount of memory, in MiB. If this parameter is not specified, there is no minimum limit.

            • Max (integer) –

              The maximum amount of memory, in MiB. If this parameter is not specified, there is no maximum limit.

            • For instance types with Intel CPUs, specify intel.

            • For instance types with AMD CPUs, specify amd.

            • For instance types with Amazon Web Services CPUs, specify amazon-web-services.

            Note

            Don’t confuse the CPU manufacturer with the CPU architecture. Instances will be launched with a compatible CPU architecture based on the Amazon Machine Image (AMI) that you specify in your launch template.

            Default: Any manufacturer

            • (string) –

          • MemoryGiBPerVCpu (dict) –

            The minimum and maximum amount of memory per vCPU, in GiB.

          • ExcludedInstanceTypes (list) –

            The instance types to exclude.

            You can use strings with one or more wild cards, represented by an asterisk ( *), to exclude an instance type, size, or generation. The following are examples: m5.8xlarge, c5*.*, m5a.*, r*, *3*.

            For example, if you specify c5*,Amazon EC2 will exclude the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*, Amazon EC2 will exclude all the M5a instance types, but not the M5n instance types.

            Note

            If you specify ExcludedInstanceTypes, you can’t specify AllowedInstanceTypes.

            Default: No excluded instance types

            • (string) –

          • InstanceGenerations (list) –

            Indicates whether current or previous generation instance types are included. The current generation instance types are recommended for use. Current generation instance types are typically the latest two to three generations in each instance family. For more information, see Instance types in the Amazon EC2 User Guide.

            For current generation instance types, specify current.

            For previous generation instance types, specify previous.

            Default: Current and previous generation instance types

            • (string) –

          • SpotMaxPricePercentageOverLowestPrice (integer) –

            [Price protection] The price protection threshold for Spot Instances, as a percentage higher than an identified Spot price. The identified Spot price is the Spot price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified Spot price is from the lowest priced current generation instance types, and failing that, from the lowest priced previous generation instance types that match your attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose Spot price exceeds your specified threshold.

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

            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.

            This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements.

            Note

            Only one of SpotMaxPricePercentageOverLowestPrice or MaxSpotPriceAsPercentageOfOptimalOnDemandPrice can be specified. If you don’t specify either, Amazon EC2 will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as 999999.

            Default: 100

          • OnDemandMaxPricePercentageOverLowestPrice (integer) –

            [Price protection] The price protection threshold for On-Demand Instances, as a percentage higher than an identified On-Demand price. The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose price exceeds your specified 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.

            Default: 20

            Note

            Only one of SpotMaxPricePercentageOverLowestPrice or MaxSpotPriceAsPercentageOfOptimalOnDemandPrice can be specified. If you don’t specify either, Amazon EC2 will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as 999999.

• OnDemandTargetCapacity (integer) – The number of On-Demand Instances in the fleet.

• Context (string) – Reserved.

• SpotFleetRequestId (string) –

  [REQUIRED]

  The ID of the Spot Fleet request.

• TargetCapacity (integer) – The size of the fleet.

• 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.

Return type:

dict

Returns:

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': {
        '...': '...',
    },
}
