Options¶

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--client-token (string)

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see Ensuring idempotency .

--spot-options (structure)

Describes the configuration of Spot Instances in an EC2 Fleet.

AllocationStrategy -> (string)

The strategy that determines how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet launch configuration. For more information, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide .

price-capacity-optimized (recommended)

EC2 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. EC2 Fleet then requests Spot Instances from the lowest priced of these pools.

capacity-optimized

EC2 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 capacity-optimized-prioritized . 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. capacity-optimized-prioritized is supported only if your EC2 Fleet uses a launch template. Note that if the On-Demand AllocationStrategy is set to prioritized , the same priority is applied when fulfilling On-Demand capacity.

diversified

EC2 Fleet requests instances from all of the Spot Instance pools that you specify.

lowest-price (not recommended)

Warning
We don’t recommend the lowest-price allocation strategy because it has the highest risk of interruption for your Spot Instances.

EC2 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, EC2 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.

Default: lowest-price

MaintenanceStrategies -> (structure)

The strategies for managing your Spot Instances that are at an elevated risk of being interrupted.

CapacityRebalance -> (structure)

The strategy to use when Amazon EC2 emits a signal that your Spot Instance is at an elevated risk of being interrupted.

ReplacementStrategy -> (string)

The replacement strategy to use. Only available for fleets of type maintain .

launch - EC2 Fleet launches a replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet. EC2 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 - EC2 Fleet launches a 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.

TerminationDelay -> (integer)

The amount of time (in seconds) that Amazon EC2 waits before terminating the old Spot Instance after launching a new replacement Spot Instance.

Required when ReplacementStrategy is set to launch-before-terminate .

Not valid when ReplacementStrategy is set to launch .

Valid values: Minimum value of 120 seconds. Maximum value of 7200 seconds.

InstanceInterruptionBehavior -> (string)

The behavior when a Spot Instance is interrupted.

Default: terminate

InstancePoolsToUseCount -> (integer)

The number of Spot pools across which to allocate your target Spot capacity. Supported only when Spot AllocationStrategy is set to lowest-price . EC2 Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify.

Note that EC2 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, EC2 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.

SingleInstanceType -> (boolean)

Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet.

Supported only for fleets of type instant .

SingleAvailabilityZone -> (boolean)

Indicates that the fleet launches all Spot Instances into a single Availability Zone.

Supported only for fleets of type instant .

MinTargetCapacity -> (integer)

The minimum target capacity for Spot Instances in the fleet. If this minimum capacity isn’t reached, no instances are launched.

Constraints: Maximum value of 1000 . Supported only for fleets of type instant .

At least one of the following must be specified: SingleAvailabilityZone | SingleInstanceType

MaxTotalPrice -> (string)

The maximum amount per hour for Spot Instances that you’re willing to pay. 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 Spot Instances will be interrupted more frequently than if you do not specify this parameter.

Note
If your fleet includes T instances that are configured as unlimited , and if their average CPU usage exceeds the baseline utilization, you will incur a charge for surplus credits. The MaxTotalPrice does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for MaxTotalPrice . For more information, see Surplus credits can incur charges in the Amazon EC2 User Guide .

The strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.

Supported only for fleets of type instant .

UsageStrategy -> (string)

Indicates whether to use unused Capacity Reservations for fulfilling On-Demand capacity.

If you specify use-capacity-reservations-first , the fleet uses unused Capacity Reservations to fulfill On-Demand capacity up to the target On-Demand capacity. If multiple instance pools have unused Capacity Reservations, the On-Demand allocation strategy (lowest-price or prioritized ) is applied. If the number of unused Capacity Reservations is less than the On-Demand target capacity, the remaining On-Demand target capacity is launched according to the On-Demand allocation strategy (lowest-price or prioritized ).

If you do not specify a value, the fleet fulfils the On-Demand capacity according to the chosen On-Demand allocation strategy.

--launch-template-configs (list)

The configuration for the EC2 Fleet.

(structure)

Describes a launch template and overrides.

LaunchTemplateSpecification -> (structure)

The launch template to use. You must specify either the launch template ID or launch template name in the request.

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)

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.

For fleets of type request and maintain , a maximum of 300 items is allowed across all launch templates.

(structure)

Describes overrides for a launch template.

The instance type.

mac1.metal is not supported as a launch template override.

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

MaxPrice -> (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 IDs of the subnets in which to launch the instances. Separate multiple subnet IDs using commas (for example, subnet-1234abcdeexample1, subnet-0987cdef6example2 ). A request of type instant can have only one subnet ID.

AvailabilityZone -> (string)

The Availability Zone in which to launch the instances.

WeightedCapacity -> (double)

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 lowest-price and price-capacity-optimized 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 -> (double)

The priority for the launch template override. The highest priority is launched first.

If the On-Demand AllocationStrategy is set to prioritized , EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

If the Spot AllocationStrategy is set to capacity-optimized-prioritized , EC2 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.

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

(string)

MaxSpotPriceAsPercentageOfOptimalOnDemandPrice -> (integer)

[Price protection] The price protection threshold for Spot Instances, as a percentage of 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. If no current generation C, M, or R instance type matches your attributes, then the identified 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 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 based on the per vCPU or per memory price instead of the per instance price.

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 .

BaselinePerformanceFactors -> (structure)

The baseline performance to consider, using an instance family as a baseline reference. The instance family establishes the lowest acceptable level of performance. Amazon EC2 uses this baseline to guide instance type selection, but there is no guarantee that the selected instance types will always exceed the baseline for every application. Currently, this parameter only supports CPU performance as a baseline performance factor. For more information, see Performance protection in the Amazon EC2 User Guide .

Cpu -> (structure)

The CPU performance to consider, using an instance family as the baseline reference.

References -> (list)

Specify an instance family to use as the baseline reference for CPU performance. All instance types that match your specified attributes will be compared against the CPU performance of the referenced instance family, regardless of CPU manufacturer or architecture differences.

Note
Currently, only one instance family can be specified in the list.

(structure)

Specify an instance family to use as the baseline reference for CPU performance. All instance types that match your specified attributes will be compared against the CPU performance of the referenced instance family, regardless of CPU manufacturer or architecture.

Note
Currently, only one instance family can be specified in the list.

InstanceFamily -> (string)

The instance family to use as a baseline reference.

Note
Ensure that you specify the correct value for the instance family. The instance family is everything before the period (. ) in the instance type name. For example, in the instance type c6i.large , the instance family is c6i , not c6 . For more information, see Amazon EC2 instance type naming conventions in Amazon EC2 Instance Types .

The following instance families are not supported for performance protection:

c1

g3 | g3s

hpc7g

m1 | m2

mac1 | mac2 | mac2-m1ultra | mac2-m2 | mac2-m2pro

If you enable performance protection by specifying a supported instance family, the returned instance types will exclude the above unsupported instance families.

If you specify an unsupported instance family as a value for baseline performance, the API returns an empty response for and an exception for , , , and .

ImageId -> (string)

The ID of the AMI in the format ami-17characters00000 .

Alternatively, you can specify a Systems Manager parameter, using one of the following formats. The Systems Manager parameter will resolve to an AMI ID on launch.

To reference a public parameter:

``resolve:ssm:public-parameter ``

To reference a parameter stored in the same account:

``resolve:ssm:parameter-name ``

``resolve:ssm:parameter-name:version-number ``

``resolve:ssm:parameter-name:label ``

--type (string)

The fleet type. The default value is maintain .

maintain - The EC2 Fleet places an asynchronous request for your desired capacity, and continues to maintain your desired Spot capacity by replenishing interrupted Spot Instances.

request - The EC2 Fleet places an asynchronous one-time request for your desired capacity, but does submit Spot requests in alternative capacity pools if Spot capacity is unavailable, and does not maintain Spot capacity if Spot Instances are interrupted.

instant - The EC2 Fleet places a synchronous one-time request for your desired capacity, and returns errors for any instances that could not be launched.

For more information, see EC2 Fleet request types in the Amazon EC2 User Guide .

Possible values:

request

maintain

instant

--valid-from (timestamp)

The start date and time of the request, in UTC format (for example, YYYY -MM -DD T*HH* :MM :SS Z). The default is to start fulfilling the request immediately.

--valid-until (timestamp)

The end date and time of the request, in UTC format (for example, YYYY -MM -DD T*HH* :MM :SS Z). At this point, no new EC2 Fleet requests are placed or able to fulfill the request. If no value is specified, the request remains until you cancel it.

--context (string)

Reserved.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To create an EC2 Fleet that launches Spot Instances as the default purchasing model

The following create-fleet example creates an EC2 Fleet using the minimum parameters required to launch a fleet: a launch template, target capacity, and default purchasing model. The launch template is identified by its launch template ID and version number. The target capacity for the fleet is 2 instances, and the default purchasing model is spot, which results in the fleet launching 2 Spot Instances.

When you create an EC2 Fleet, use a JSON file to specify information about the instances to launch.

aws ec2 create-fleet \
    --cli-input-json file://file_name.json

Contents of file_name.json:

{
    "LaunchTemplateConfigs": [
    {
        "LaunchTemplateSpecification": {
        "LaunchTemplateId": "lt-0e8c754449b27161c",
        "Version": "1"
        }
    }
    ],
    "TargetCapacitySpecification": {
        "TotalTargetCapacity": 2,
        "DefaultTargetCapacityType": "spot"
    }
}

Output:

{
    "FleetId": "fleet-12a34b55-67cd-8ef9-ba9b-9208dEXAMPLE"
}

Example 2: To create an EC2 Fleet that launches On-Demand Instances as the default purchasing model

The following create-fleet example creates an EC2 Fleet using the minimum parameters required to launch a fleet: a launch template, target capacity, and default purchasing model. The launch template is identified by its launch template ID and version number. The target capacity for the fleet is 2 instances, and the default purchasing model is on-demand, which results in the fleet launching 2 On-Demand Instances.

When you create an EC2 Fleet, use a JSON file to specify information about the instances to launch.

aws ec2 create-fleet \
    --cli-input-json file://file_name.json

Contents of file_name.json:

{
    "LaunchTemplateConfigs": [
    {
        "LaunchTemplateSpecification": {
        "LaunchTemplateId": "lt-0e8c754449b27161c",
        "Version": "1"
        }
    }
    ],
    "TargetCapacitySpecification": {
    "TotalTargetCapacity": 2,
    "DefaultTargetCapacityType": "on-demand"
    }
}

Output:

{
    "FleetId": "fleet-12a34b55-67cd-8ef9-ba9b-9208dEXAMPLE"
}

Example 3: To create an EC2 Fleet that launches On-Demand Instances as the primary capacity

The following create-fleet example creates an EC2 Fleet that specifies the total target capacity of 2 instances for the fleet, and a target capacity of 1 On-Demand Instance. The default purchasing model is spot. The fleet launches 1 On-Demand Instance as specified, but needs to launch one more instance to fulfil the total target capacity. The purchasing model for the difference is calculated as TotalTargetCapacity - OnDemandTargetCapacity = DefaultTargetCapacityType, which results in the fleet launching 1 Spot Instance.

When you create an EC2 Fleet, use a JSON file to specify information about the instances to launch.

aws ec2 create-fleet \
    --cli-input-json file://file_name.json

Contents of file_name.json:

{
    "LaunchTemplateConfigs": [
    {
        "LaunchTemplateSpecification": {
        "LaunchTemplateId": "lt-0e8c754449b27161c",
        "Version": "1"
        }
    }
    ],
    "TargetCapacitySpecification": {
        "TotalTargetCapacity": 2,
        "OnDemandTargetCapacity":1,
        "DefaultTargetCapacityType": "spot"
    }
}

Output:

{
    "FleetId": "fleet-12a34b55-67cd-8ef9-ba9b-9208dEXAMPLE"
}

Example 4: To create an EC2 Fleet that launches Spot Instances using the lowest-price allocation strategy

If the allocation strategy for Spot Instances is not specified, the default allocation strategy, which is lowest-price, is used. The following create-fleet example creates an EC2 Fleet using the lowest-price allocation strategy. The three launch specifications, which override the launch template, have different instance types but the same weighted capacity and subnet. The total target capacity is 2 instances and the default purchasing model is spot. The EC2 Fleet launches 2 Spot Instances using the instance type of the launch specification with the lowest price.

When you create an EC2 Fleet, use a JSON file to specify information about the instances to launch.

aws ec2 create-fleet \
    --cli-input-json file://file_name.jsonContents of file_name.json::

{
    "LaunchTemplateConfigs": [
    {
        "LaunchTemplateSpecification": {
        "LaunchTemplateId": "lt-0e8c754449b27161c",
        "Version": "1"
        },
        "Overrides": [
            {
                "InstanceType": "c4.large",
                "WeightedCapacity": 1,
                "SubnetId": "subnet-a4f6c5d3"
            },
            {
                "InstanceType": "c3.large",
                "WeightedCapacity": 1,
                "SubnetId": "subnet-a4f6c5d3"
            },
            {
                "InstanceType": "c5.large",
                "WeightedCapacity": 1,
                "SubnetId": "subnet-a4f6c5d3"
            }
        ]
    }
    ],
    "TargetCapacitySpecification": {
        "TotalTargetCapacity": 2,
        "DefaultTargetCapacityType": "spot"
    }
}

Output:

{
    "FleetId": "fleet-12a34b55-67cd-8ef9-ba9b-9208dEXAMPLE"
}

Output¶

FleetId -> (string)

The ID of the EC2 Fleet.

Errors -> (list)

Information about the instances that could not be launched by the fleet. Supported only for fleets of type instant .

(structure)

Describes the instances that could not be launched by the fleet.

LaunchTemplateAndOverrides -> (structure)

The launch templates and overrides that were used for launching the instances. The values that you specify in the Overrides replace the values in the launch template.

LaunchTemplateSpecification -> (structure)

The launch template.

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 -> (structure)

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

InstanceType -> (string)

The instance type.

mac1.metal is not supported as a launch template override.

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

MaxPrice -> (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 -> (double)

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 lowest-price and price-capacity-optimized 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 -> (double)

The priority for the launch template override. The highest priority is launched first.

If the On-Demand AllocationStrategy is set to prioritized , EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

If the Spot AllocationStrategy is set to capacity-optimized-prioritized , EC2 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 override has the lowest priority. You can set the same priority for different launch template overrides.

Placement -> (structure)

The location where the instance launched, if applicable.

GroupName -> (string)

The name of the placement group that the instance is in.

InstanceRequirements -> (structure)

The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.

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

VCpuCount -> (structure)

The minimum and maximum number of vCPUs.

Min -> (integer)

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

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 -> (structure)

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

Default: No minimum or maximum limits

Min -> (double)

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

Max -> (double)

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

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 .

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

BareMetal -> (string)

Indicates whether bare metal instance types must be included, excluded, or required.

To include bare metal instance types, specify included .

To require only bare metal instance types, specify required .

MaxSpotPriceAsPercentageOfOptimalOnDemandPrice -> (integer)

[Price protection] The price protection threshold for Spot Instances, as a percentage of 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. If no current generation C, M, or R instance type matches your attributes, then the identified 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 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 based on the per vCPU or per memory price instead of the per instance price.

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.

mac1.metal is not supported as a launch template override.

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

MaxPrice -> (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.

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.

The Availability Zone in which to launch the instances.

WeightedCapacity -> (double)

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 lowest-price and price-capacity-optimized 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 -> (double)

The priority for the launch template override. The highest priority is launched first.

If the On-Demand AllocationStrategy is set to prioritized , EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

If the Spot AllocationStrategy is set to capacity-optimized-prioritized , EC2 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 override has the lowest priority. You can set the same priority for different launch template overrides.
