modify-spot-fleet-request

Description

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.

Options

--excess-capacity-termination-policy (string)

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

Possible values:

• noTermination

• default

--launch-template-configs (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.

(structure)

Describes a launch template and overrides.

LaunchTemplateSpecification -> (structure)

The launch template.

LaunchTemplateId -> (string)

The ID of the launch template. If you specify the template ID, you can’t specify the template name.

LaunchTemplateName -> (string)

The name of the launch template. If you specify the template name, you can’t specify the template ID.

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.

(structure)

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.

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 -> (double)

The number of units provided by the specified instance type.

Priority -> (double)

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 first 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.

--spot-fleet-request-id (string)

The ID of the Spot Fleet request.

--target-capacity (integer)

The size of the fleet.

--on-demand-target-capacity (integer)

The number of On-Demand Instances in the fleet.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To modify a Spot fleet request

This example command updates the target capacity of the specified Spot fleet request.

Command:

aws ec2 modify-spot-fleet-request --target-capacity 20 --spot-fleet-request-id sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE

Output:

{
    "Return": true
}

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

Command:

aws ec2 modify-spot-fleet-request --target-capacity 10 --excess-capacity-termination-policy NoTermination --spot-fleet-request-ids sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE

Output:

{
    "Return": true
}

Output

Return -> (boolean)

Is true if the request succeeds, and an error otherwise.
