    #   currently available to you.
    #   @return [String]
    #
    # @!attribute [rw] encrypted
    #   Specifies whether the volume should be encrypted. Encrypted Amazon
    #   EBS volumes may only be attached to instances that support Amazon
    #   EBS encryption. Volumes that are created from encrypted snapshots
    #   are automatically encrypted. There is no way to create an encrypted
    #   volume from an unencrypted snapshot or vice versa. If your AMI uses
    #   encrypted volumes, you can only launch it on supported instance
    #   types. For more information, see [Amazon EBS Encryption][1] in the
    #   *Amazon Elastic Compute Cloud User Guide*.

    # @!attribute [rw] iops
    #   The number of I/O operations per second (IOPS) to provision for the
    #   volume, with a maximum ratio of 50 IOPS/GiB. Range is 100 to 32000
    #   IOPS for volumes in most regions. For exceptions, see [Amazon EBS
    #   Volume Types][1] in the *Amazon Elastic Compute Cloud User Guide*.
    #
    #   This parameter is valid only for Provisioned IOPS SSD (io1) volumes.

    #   @return [Integer]
    #
    # @!attribute [rw] kms_key_id
    #   An identifier for the AWS Key Management Service (AWS KMS) customer
    #   master key (CMK) to use when creating the encrypted volume. This
    #   parameter is only required if you want to use a non-default CMK; if
    #   this parameter is not specified, the default CMK for EBS is used. If
    #   a `KmsKeyId` is specified, the `Encrypted` flag must also be set.
    #
    #   The CMK identifier may be provided in any of the following formats:
    #
    #   * Key ID
    #
    #   * Key alias
    #
    #   * ARN using key ID. The ID ARN contains the `arn:aws:kms` namespace,
    #     followed by the region of the CMK, the AWS account ID of the CMK
    #     owner, the `key` namespace, and then the CMK ID. For example,
    #     arn:aws:kms:*us-east-1*\:*012345678910*\:key/*abcd1234-a123-456a-a12b-a123b4cd56ef*.
    #
    #   * ARN using key alias. The alias ARN contains the `arn:aws:kms`
    #     namespace, followed by the region of the CMK, the AWS account ID
    #     of the CMK owner, the `alias` namespace, and then the CMK alias.
    #     For example,
    #     arn:aws:kms:*us-east-1*\:*012345678910*\:alias/*ExampleAlias*.
    #
    #   AWS parses `KmsKeyId` asynchronously, meaning that the action you
    #   call may appear to complete even though you provided an invalid
    #   identifier. The action will eventually fail.
    #   @return [String]
    #
    # @!attribute [rw] size
    #   The size of the volume, in GiBs.
    #
    #   Constraints: 1-16384 for `gp2`, 4-16384 for `io1`, 500-16384 for
    #   `st1`, 500-16384 for `sc1`, and 1-1024 for `standard`. If you
    #   specify a snapshot, the volume size must be equal to or larger than
    #   the snapshot size.
    #
    #   Default: If you're creating the volume from a snapshot and don't
    #   specify a volume size, the default is the snapshot size.
    #   @return [Integer]
    #
    # @!attribute [rw] snapshot_id
    #   The snapshot from which to create the volume.
    #   @return [String]
    #
    # @!attribute [rw] volume_type
    #   The volume type. This can be `gp2` for General Purpose SSD, `io1`
    #   for Provisioned IOPS SSD, `st1` for Throughput Optimized HDD, `sc1`
    #   for Cold HDD, or `standard` for Magnetic volumes.
    #
    #   Defaults: If no volume type is specified, the default is `standard`
    #   in us-east-1, eu-west-1, eu-central-1, us-west-2, us-west-1,
    #   sa-east-1, ap-northeast-1, ap-northeast-2, ap-southeast-1,
    #   ap-southeast-2, ap-south-1, us-gov-west-1, and cn-north-1. In all
    #   other regions, EBS defaults to `gp2`.

    #   * `iamFleetRoleInvalid` - The Spot Fleet did not have the required
    #     permissions either to launch or terminate an instance.
    #
    #   * `launchSpecTemporarilyBlacklisted` - The configuration is not
    #     valid and several attempts to launch instances have failed. For
    #     more information, see the description of the event.
    #
    #   * `spotFleetRequestConfigurationInvalid` - The configuration is not
    #     valid. For more information, see the description of the event.
    #
    #   * `spotInstanceCountLimitExceeded` - You've reached the limit on
    #     the number of Spot Instances that you can launch.
    #
    #   The following are the `fleetRequestChange` events:
    #
    #   * `active` - The Spot Fleet has been validated and Amazon EC2 is
    #     attempting to maintain the target number of running Spot
    #     Instances.
    #
    #   * `cancelled` - The Spot Fleet is canceled and has no running Spot
    #     Instances. The Spot Fleet will be deleted two days after its
    #     instances were terminated.
    #
    #   * `cancelled_running` - The Spot Fleet is canceled and does not
    #     launch additional Spot Instances. Existing Spot Instances continue
    #     to run until they are interrupted or terminated.
    #
    #   * `cancelled_terminating` - The Spot Fleet is canceled and its Spot
    #     Instances are terminating.
    #
    #   * `expired` - The Spot Fleet request has expired. A subsequent event
    #     indicates that the instances were terminated, if the request was
    #     created with `TerminateInstancesWithExpiration` set.
    #
    #   * `modify_in_progress` - A request to modify the Spot Fleet request
    #     was accepted and is in progress.
    #
    #   * `modify_successful` - The Spot Fleet request was modified.
    #
    #   * `price_update` - The price for a launch configuration was adjusted
    #     because it was too high. This change is permanent.
    #
    #   * `submitted` - The Spot Fleet request is being evaluated and Amazon
    #     EC2 is preparing to launch the target number of Spot Instances.
    #
    #   The following are the `instanceChange` events:
    #
    #   * `launched` - A request was fulfilled and a new instance was
    #     launched.
    #
    #   * `terminated` - An instance was terminated by the user.
    #
    #   The following are the `Information` events:
    #
    #   * `launchSpecUnusable` - The price in a launch specification is not
    #     valid because it is below the Spot price or the Spot price is
    #     above the On-Demand price.
    #
    #   * `fleetProgressHalted` - The price in every launch specification is
    #     not valid. A launch specification might become valid if the Spot
    #     price changes.

    #   request, all Spot Instances in the request are launched in the same

    #   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.

    #   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

    #   180, 240, 300, or 360).
    #
    #   The duration period starts as soon as your Spot Instance receives
    #   its instance ID. At the end of the duration period, Amazon EC2 marks
    #   the Spot Instance for termination and provides a Spot Instance
    #   termination notice, which gives the instance a two-minute warning
    #   before it terminates.
