request-spot-fleet

Description

Creates a Spot Fleet request.

The Spot Fleet request specifies the total target capacity and the On-Demand target capacity. Amazon EC2 calculates the difference between the total capacity and On-Demand capacity, and launches the difference as Spot capacity.

You can submit a single request that includes multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet.

By default, the Spot Fleet requests Spot Instances in the Spot Instance pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload.

Alternatively, you can specify that the Spot Fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot Instances in your Spot Fleet are in different Spot pools, you can improve the availability of your fleet.

You can specify tags for the Spot Fleet request and instances launched by the fleet. You cannot tag other resource types in a Spot Fleet request because only the spot-fleet-request and instance resource types are supported.

For more information, see Spot Fleet requests in the Amazon EC2 User Guide for Linux Instances .

--spot-fleet-request-config (structure)

The configuration for the Spot Fleet request.

AllocationStrategy -> (string)

Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the Spot Fleet request.

If the allocation strategy is lowestPrice , Spot Fleet launches instances from the Spot Instance pools with the lowest price. This is the default allocation strategy.

If the allocation strategy is diversified , Spot Fleet launches instances from all the Spot Instance pools that you specify.

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.

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 .

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 AWS Identity and Access Management (IAM) role that grants the Spot Fleet the permission to request, launch, terminate, and tag instances on your behalf.

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, 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.

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.

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 Elastic Compute Cloud User Guide.

Iops -> (integer)

The number of I/O operations per second (IOPS) that the volume supports. For io1 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. For more information, see Amazon EBS volume types in the Amazon Elastic Compute Cloud User Guide .

Constraints: Range is 100-16,000 IOPS for gp2 volumes and 100 to 64,000IOPS for io1 volumes in most Regions. Maximum io1 IOPS of 64,000 is guaranteed only on Nitro-based instances . Other instance families guarantee performance up to 32,000 IOPS. For more information, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide .

Condition: This parameter is required for requests to create io1 volumes; it is not used in requests to create gp2 , st1 , sc1 , or standard volumes.

SnapshotId -> (string)

The ID of the snapshot.

VolumeSize -> (integer)

The size of the volume, in GiB.

Default: If you’re creating the volume from a snapshot and don’t specify a volume size, the default is the snapshot size.

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

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 Elastic Compute Cloud 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 .

NoDevice -> (string)

Suppresses the specified device included in the block device mapping of the AMI.

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.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To request a Spot fleet in the subnet with the lowest price

This example command creates a Spot fleet request with two launch specifications that differ only by subnet. The Spot fleet launches the instances in the specified subnet with the lowest price. If the instances are launched in a default VPC, they receive a public IP address by default. If the instances are launched in a nondefault VPC, they do not receive a public IP address by default.

Note that you can’t specify different subnets from the same Availability Zone in a Spot fleet request.

Command:

aws ec2 request-spot-fleet --spot-fleet-request-config file://config.json

Config.json:

{
  "SpotPrice": "0.04",
  "TargetCapacity": 2,
  "IamFleetRole": "arn:aws:iam::123456789012:role/my-spot-fleet-role",

          }
      }
  ]
}

Output:

{
  "SpotFleetRequestId": "sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE"
}

To request a Spot fleet in the Availability Zone with the lowest price

This example command creates a Spot fleet request with two launch specifications that differ only by Availability Zone. The Spot fleet launches the instances in the specified Availability Zone with the lowest price. If your account supports EC2-VPC only, Amazon EC2 launches the Spot instances in the default subnet of the Availability Zone. If your account supports EC2-Classic, Amazon EC2 launches the instances in EC2-Classic in the Availability Zone.

To launch Spot instances in a subnet and assign them public IP addresses

This example command assigns public addresses to instances launched in a nondefault VPC. Note that when you specify a network interface, you must include the subnet ID and security group ID using the network interface.

To request a Spot fleet using the diversified allocation strategy

This example command creates a Spot fleet request that launches 30 instances using the diversified allocation strategy. The launch specifications differ by instance type. The Spot fleet distributes the instances across the launch specifications such that there are 10 instances of each type.

Command:

aws ec2 request-spot-fleet --spot-fleet-request-config file://config.json

Config.json:

{
  "SpotPrice": "0.70",
  "TargetCapacity": 30,
  "AllocationStrategy": "diversified",
  "IamFleetRole": "arn:aws:iam::123456789012:role/my-spot-fleet-role",
  "LaunchSpecifications": [
      {
          "ImageId": "ami-1a2b3c4d",
          "InstanceType": "c4.2xlarge",
          "SubnetId": "subnet-1a2b3c4d"
      },
      {
          "ImageId": "ami-1a2b3c4d",
          "InstanceType": "m3.2xlarge",
          "SubnetId": "subnet-1a2b3c4d"
      },
      {
          "ImageId": "ami-1a2b3c4d",
          "InstanceType": "r3.2xlarge",
          "SubnetId": "subnet-1a2b3c4d"
