describe-spot-fleet-requests

Description

Describes your Spot Fleet requests.

Spot Fleet requests are deleted 48 hours after they are canceled and their instances are terminated.

See also: AWS API Documentation

describe-spot-fleet-requests is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: SpotFleetRequestConfigs

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 (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

--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.

      }
  ]
}

Output

NextToken -> (string)

The token to include in another request to get the next page of items. This value is null when there are no more items 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 (not recommended)

Warning

We don't recommend the lowestPrice allocation strategy because it has the highest risk of interruption for your Spot Instances.

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 .

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 instances should be terminated if you decrease the target capacity of the Spot Fleet request below the current size of the Spot Fleet.

Supported only for fleets of type maintain .

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 .

Note

If an AMI specified in a launch specification is deregistered or disabled, no new instances can be launched from the AMI. For fleets of type maintain , the target capacity will not be maintained.

(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 .

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.

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 - 256,000 IOPS

For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System . On other instances, you can achieve performance up to 32,000 IOPS.

This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS.

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 sizes for each volume type:

  • gp2 and gp3 : 1 - 16,384 GiB
  • io1 : 4 - 16,384 GiB
  • io2 : 4 - 65,536 GiB
  • st1 and sc1 : 125 - 16,384 GiB
  • standard : 1 - 1024 GiB

VolumeType -> (string)

The volume type. For more information, see Amazon EBS volume types in the Amazon EBS User Guide .

KmsKeyId -> (string)

Identifier (key ID, key alias, key ARN, or alias ARN) of the customer managed KMS key to use for EBS encryption.

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 not supported when using 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 EBS 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 .

For CreateImage and RegisterImage , whether you can include this parameter, and the allowed values differ depending on the type of block device mapping you are creating.

  • If you are creating a block device mapping for a new (empty) volume , you can include this parameter, and specify either true for an encrypted volume, or false for an unencrypted volume. If you omit this parameter, it defaults to false (unencrypted).
  • If you are creating a block device mapping from an existing encrypted or unencrypted snapshot , you must omit this parameter. If you include this parameter, the request will fail, regardless of the value that you specify.
  • If you are creating a block device mapping from an existing unencrypted volume , you can include this parameter, but you must specify false . If you specify true , the request will fail. In this case, we recommend that you omit the parameter.
  • If you are creating a block device mapping from an existing encrypted volume , you can include this parameter, and specify either true or false . However, if you specify false , the parameter is ignored and the block device mapping is always encrypted. In this case, we recommend that you omit the parameter.

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.

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.

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.

ImageId -> (string)

The ID of the AMI.

InstanceType -> (string)

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)

The network interfaces.

Note

SpotFleetLaunchSpecification does not support Elastic Fabric Adapter (EFA). You must use LaunchTemplateConfig instead.

(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 .

Amazon Web Services charges for all public IPv4 addresses, including public IPv4 addresses associated with running instances and Elastic IP addresses. For more information, see the Public IPv4 Address tab on the Amazon VPC pricing page .

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)

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 .

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.

TargetCapacity -> (integer)

The number of units to request for the Spot Fleet. You can choose to set the target capacity in terms of instances or a performance characteristic that is important to your application workload, such as vCPUs, memory, or I/O. If the request type is maintain , you can specify a target capacity of 0 and add capacity later.

OnDemandTargetCapacity -> (integer)

The number of On-Demand units to request. You can choose to set the target capacity in terms of instances or a performance characteristic that is important to your application workload, such as vCPUs, memory, or I/O. If the request type is maintain , you can specify a target capacity of 0 and add capacity later.

OnDemandMaxTotalPrice -> (string)

The maximum amount per hour for On-Demand Instances that you're willing to pay. You can use the onDemandMaxTotalPrice parameter, the spotMaxTotalPrice parameter, or both parameters to ensure that your fleet cost does not exceed your budget. If you set a maximum price per hour for the On-Demand Instances and Spot Instances in your request, Spot Fleet will launch instances until it reaches the maximum amount you're willing to pay. When the maximum amount you're willing to pay is reached, the fleet stops launching instances even if it hasn’t met the target capacity.

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 onDemandMaxTotalPrice does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for onDemandMaxTotalPrice . For more information, see Surplus credits can incur charges in the Amazon EC2 User Guide .

SpotMaxTotalPrice -> (string)

The maximum amount per hour for Spot Instances that you're willing to pay. You can use the spotMaxTotalPrice parameter, the onDemandMaxTotalPrice parameter, or both parameters to ensure that your fleet cost does not exceed your budget. If you set a maximum price per hour for the On-Demand Instances and Spot Instances in your request, Spot Fleet will launch instances until it reaches the maximum amount you're willing to pay. When the maximum amount you're willing to pay is reached, the fleet stops launching instances even if it hasn’t met the target capacity.

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 spotMaxTotalPrice does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for spotMaxTotalPrice . For more information, see Surplus credits can incur charges in the Amazon EC2 User Guide .

TerminateInstancesWithExpiration -> (boolean)

Indicates whether running Spot Instances are terminated when the Spot Fleet request expires.

Type -> (string)

The type of request. Indicates whether the Spot Fleet only requests the target capacity or also attempts to maintain it. When this value is request , the Spot Fleet only places the required requests. It does not attempt to replenish Spot Instances if capacity is diminished, nor does it submit requests in alternative Spot pools if capacity is not available. When this value is maintain , the Spot Fleet maintains the target capacity. The Spot Fleet places the required requests to meet capacity and automatically replenishes any interrupted instances. Default: maintain . instant is listed but is not used by Spot Fleet.

ValidFrom -> (timestamp)

The start date and time of the request, in UTC format (YYYY -MM -DD T*HH* :MM :SS Z). By default, Amazon EC2 starts fulfilling the request immediately.

ValidUntil -> (timestamp)

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

Indicates whether Spot Fleet should replace unhealthy instances.

InstanceInterruptionBehavior -> (string)

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.

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. You can specify this parameter only when using attribute-based instance type selection.

Default: units (the number of instances)
