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 .

--spot-fleet-request-ids (list)

The IDs of the Spot Fleet requests.

(string)

Syntax:

"string" "string" ...

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

--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 .

Output¶

NextToken -> (string)

The token required to retrieve the next set of results. This value is null when there are no more results to return.

SpotFleetRequestConfigs -> (list)

Information about the configuration of your Spot Fleet.

(structure)

Describes a Spot Fleet request.

ActivityStatus -> (string)

The progress of the Spot Fleet request. If there is an error, the status is error . After all requests are placed, the status is pending_fulfillment . If the size of the fleet is equal to or greater than its target capacity, the status is fulfilled . If the size of the fleet is decreased, the status is pending_termination while Spot Instances are terminating.

CreateTime -> (timestamp)

The creation date and time of the request.

SpotFleetRequestConfig -> (structure)

The configuration of the Spot Fleet request.

AllocationStrategy -> (string)

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

priceCapacityOptimized (recommended)

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

capacityOptimized

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

diversified

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

lowestPrice

Spot 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, Spot 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: lowestPrice

OnDemandAllocationStrategy -> (string)

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 specify prioritized , 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 to lowestPrice .

SpotMaintenanceStrategies -> (structure)

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

CapacityRebalance -> (structure)

The Spot Instance replacement strategy to use when Amazon EC2 emits a signal that your Spot Instance is at an elevated risk of being interrupted. For more information, see Capacity rebalancing in the Amazon EC2 User Guide for Linux Instances .

ReplacementStrategy -> (string)

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

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

ClientToken -> (string)

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 .

ExcessCapacityTerminationPolicy -> (string)

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.

FulfilledCapacity -> (double)

The number of units fulfilled by this request compared to the set target capacity. You cannot set this value.

OnDemandFulfilledCapacity -> (double)

The number of On-Demand units fulfilled by this request compared to the set target On-Demand capacity.

IamFleetRole -> (string)

The Amazon Resource Name (ARN) of an 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 . 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 .

LaunchSpecifications -> (list)

The launch specifications for the Spot Fleet request. If you specify LaunchSpecifications , you can’t specify LaunchTemplateConfigs . If you include On-Demand capacity in your request, you must use LaunchTemplateConfigs .

(structure)

Describes the launch specification for one or more Spot Instances. If you include On-Demand capacity in your fleet request or want to specify an EFA network device, you can’t use SpotFleetLaunchSpecification ; you must use LaunchTemplateConfig .

SecurityGroups -> (list)

One or more security groups. When requesting instances in a VPC, you must specify the IDs of the security groups. When requesting instances in EC2-Classic, you can specify the names or the IDs of the security groups.

(structure)

Describes a security group.

GroupName -> (string)

The name of the security group.

GroupId -> (string)

The ID of the security group.

AddressingType -> (string)

Deprecated.

BlockDeviceMappings -> (list)

One or more block devices that are mapped to the Spot Instances. You can’t specify both a snapshot ID and an encryption value. This is because only blank volumes can be encrypted on creation. If a snapshot is the basis for a volume, it is not blank and its encryption status is used for the volume encryption status.

(structure)

Describes a block device mapping, which defines the EBS volumes and instance store volumes to attach to an instance at launch.

DeviceName -> (string)

The device name (for example, /dev/sdh or xvdh ).

VirtualName -> (string)

The virtual device name (ephemeral N). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ephemeral0 and ephemeral1 . The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.

NVMe instance store volumes are automatically enumerated and assigned a device name. Including them in your block device mapping has no effect.

Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI.

Ebs -> (structure)

Parameters used to automatically set up EBS volumes when the instance is launched.

DeleteOnTermination -> (boolean)

Indicates whether the EBS volume is deleted on instance termination. For more information, see Preserving Amazon EBS volumes on instance termination in the Amazon EC2 User Guide .

Iops -> (integer)

The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

The following are the supported values for each volume type:

gp3 : 3,000-16,000 IOPS

io1 : 100-64,000 IOPS

io2 : 100-64,000 IOPS

For io1 and io2 volumes, we guarantee 64,000 IOPS only for Instances built on the Nitro System . Other instance families guarantee performance up to 32,000 IOPS.

This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for gp2 , st1 , sc1 , or standard volumes.

SnapshotId -> (string)

The ID of the snapshot.

VolumeSize -> (integer)

The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. If you specify a snapshot, the default is the snapshot size. You can specify a volume size that is equal to or larger than the snapshot size.

The following are the supported volumes sizes for each volume type:

gp2 and gp3 :1-16,384

io1 and io2 : 4-16,384

st1 and sc1 : 125-16,384

standard : 1-1,024

VolumeType -> (string)

The volume type. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide . If the volume type is io1 or io2 , you must specify the IOPS that the volume supports.

KmsKeyId -> (string)

Identifier (key ID, key alias, ID ARN, or alias ARN) for a customer managed CMK under which the EBS volume is encrypted.

This parameter is only supported on BlockDeviceMapping objects called by RunInstances , RequestSpotFleet , and RequestSpotInstances .

Throughput -> (integer)

The throughput that the volume supports, in MiB/s.

This parameter is valid only for gp3 volumes.

Valid Range: Minimum value of 125. Maximum value of 1000.

OutpostArn -> (string)

The ARN of the Outpost on which the snapshot is stored.

This parameter is only supported on BlockDeviceMapping objects called by CreateImage .

Encrypted -> (boolean)

Indicates whether the encryption state of an EBS volume is changed while being restored from a backing snapshot. The effect of setting the encryption state to true depends on the volume origin (new or from a snapshot), starting encryption state, ownership, and whether encryption by default is enabled. For more information, see Amazon EBS encryption in the Amazon EC2 User Guide .

In no case can you remove encryption from an encrypted volume.

Encrypted volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types .

This parameter is not returned by DescribeImageAttribute .

NoDevice -> (string)

To omit the device from the block device mapping, specify an empty string. When this property is specified, the device is removed from the block device mapping regardless of the assigned value.

EbsOptimized -> (boolean)

Indicates whether the instances are optimized for EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal EBS I/O performance. This optimization isn’t available with all instance types. Additional usage charges apply when using an EBS Optimized instance.

Default: false

IamInstanceProfile -> (structure)

The IAM instance profile.

Arn -> (string)

The Amazon Resource Name (ARN) of the instance profile.

Name -> (string)

The name of the instance profile.

The instance type.

KernelId -> (string)

The ID of the kernel.

KeyName -> (string)

The name of the key pair.

Monitoring -> (structure)

Enable or disable monitoring for the instances.

Enabled -> (boolean)

Enables monitoring for the instance.

Default: false

NetworkInterfaces -> (list)

One or more network interfaces. If you specify a network interface, you must specify subnet IDs and security group IDs using the network interface.

Note

SpotFleetLaunchSpecification currently does not support Elastic Fabric Adapter (EFA). To specify an EFA, you must use LaunchTemplateConfig .

(structure)

Describes a network interface.

AssociatePublicIpAddress -> (boolean)

Indicates whether to assign a public IPv4 address to an instance you launch in a VPC. The public IP address can only be assigned to a network interface for eth0, and can only be assigned to a new network interface, not an existing one. You cannot specify more than one network interface in the request. If launching into a default subnet, the default value is true .

DeleteOnTermination -> (boolean)

If set to true , the interface is deleted when the instance is terminated. You can specify true only if creating a new network interface when launching an instance.

Description -> (string)

The description of the network interface. Applies only if creating a network interface when launching an instance.

DeviceIndex -> (integer)

The position of the network interface in the attachment order. A primary network interface has a device index of 0.

If you specify a network interface when launching an instance, you must specify the device index.

Groups -> (list)

The IDs of the security groups for the network interface. Applies only if creating a network interface when launching an instance.

(string)

Ipv6AddressCount -> (integer)

A number of IPv6 addresses to assign to the network interface. Amazon EC2 chooses the IPv6 addresses from the range of the subnet. You cannot specify this option and the option to assign specific IPv6 addresses in the same request. You can specify this option if you’ve specified a minimum number of instances to launch.

Ipv6Addresses -> (list)

The IPv6 addresses to assign to the network interface. You cannot specify this option and the option to assign a number of IPv6 addresses in the same request. You cannot specify this option if you’ve specified a minimum number of instances to launch.

(structure)

Describes an IPv6 address.

The behavior when a Spot Instance is interrupted. The default is terminate .

LoadBalancersConfig -> (structure)

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.

ClassicLoadBalancersConfig -> (structure)

The Classic Load Balancers.

ClassicLoadBalancers -> (list)

One or more Classic Load Balancers.

(structure)

Describes a Classic Load Balancer.

Name -> (string)

The name of the load balancer.

TargetGroupsConfig -> (structure)

The target groups.

TargetGroups -> (list)

One or more target groups.

(structure)

Describes a load balancer target group.

Arn -> (string)

The Amazon Resource Name (ARN) of the target group.

InstancePoolsToUseCount -> (integer)

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.

Note that Spot 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, Spot 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.

Context -> (string)

Reserved.

TargetCapacityUnitType -> (string)

The unit for the target capacity. TargetCapacityUnitType can only be specified when InstanceRequirements is specified.

Default: units (translates to number of instances)

TagSpecifications -> (list)

The key-value pair for tagging the Spot Fleet request on creation. The value for ResourceType must be spot-fleet-request , otherwise the Spot Fleet request fails. To tag instances at launch, specify the tags in the launch template (valid only if you use LaunchTemplateConfigs ) or in the `` SpotFleetTagSpecification `` (valid only if you use LaunchSpecifications ). For information about tagging after launch, see Tagging Your Resources .

(structure)

The tags to apply to a resource when the resource is being created.

Note

The Valid Values lists all the resource types that can be tagged. However, the action you’re using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you’re using, you’ll get an error.
