request_spot_instances#

EC2.Client.request_spot_instances(**kwargs)#

Creates a Spot Instance request.

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

Warning

We strongly discourage using the RequestSpotInstances API because it is a legacy API with no planned investment. For options for requesting Spot Instances, see Which is the best Spot request method to use? in the Amazon EC2 User Guide for Linux Instances.

Note

We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon EC2 User Guide for Linux Instances.

Parameters:

  • AvailabilityZoneGroup (string) –

    The user-specified name for a logical grouping of requests.

    When you specify an Availability Zone group in a Spot Instance request, all Spot Instances in the request are launched in the same Availability Zone. Instance proximity is maintained with this parameter, but the choice of Availability Zone is not. The group applies only to requests for Spot Instances of the same instance type. Any additional Spot Instance requests that are specified with the same Availability Zone group name are launched in that same Availability Zone, as long as at least one instance from the group is still active.

    If there is no active instance running in the Availability Zone group that you specify for a new Spot Instance request (all instances are terminated, the request is expired, or the maximum price you specified falls below current Spot price), then Amazon EC2 launches the instance in any Availability Zone where the constraint can be met. Consequently, the subsequent set of Spot Instances could be placed in a different zone from the original request, even if you specified the same Availability Zone group.

    Default: Instances are launched in any available Availability Zone.

  • BlockDurationMinutes (integer) – Deprecated.

  • ClientToken (string) – Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to Ensure Idempotency in the Amazon EC2 User Guide for Linux Instances.

  • DryRun (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.

  • InstanceCount (integer) –

    The maximum number of Spot Instances to launch.

    Default: 1

  • LaunchGroup (string) –

    The instance launch group. Launch groups are Spot Instances that launch together and terminate together.

    Default: Instances are launched and terminated individually

  • LaunchSpecification (dict) –

    The launch specification.

    • SecurityGroupIds (list) –

      One or more security group IDs.

      • (string) –

    • 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.

      • (string) –

    • AddressingType (string) –

      Deprecated.

    • BlockDeviceMappings (list) –

      One or more block device mapping entries. 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.

      • (dict) –

        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 (dict) –

          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.

            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.

    • EbsOptimized (boolean) –

      Indicates whether the instance is 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.

    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.

  • Type (string) –

    The Spot Instance request type.

    Default: one-time

  • ValidFrom (datetime) –

    The start date of the request. If this is a one-time request, the request becomes active at this date and time and remains active until all instances launch, the request expires, or the request is canceled. If the request is persistent, the request becomes active at this date and time and remains active until it expires or is canceled.

    The specified start date and time cannot be equal to the current date and time. You must specify a start date and time that occurs after the current date and time.

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 (dict) –

                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 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.

                  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.

          • EbsOptimized (boolean) –

            Indicates whether the instance is 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
