    #     explicitly cancel it. Do not provide an `EndDate` if the
    #     `EndDateType` is `unlimited`.
    #
    #   * `limited` - The Capacity Reservation expires automatically at a

    #     the `EndDateType` value is `limited`.
    #   @return [String]
    #
    # @!attribute [rw] instance_match_criteria
    #   Indicates the type of instance launches that the Capacity
    #   Reservation accepts. The options include:
    #
    #   * `open` - The Capacity Reservation automatically matches all
    #     instances that have matching attributes (instance type, platform,
    #     and Availability Zone). Instances that have matching attributes
    #     run in the Capacity Reservation automatically without specifying
    #     any additional parameters.
    #
    #   * `targeted` - The Capacity Reservation only accepts instances that
    #     have matching attributes (instance type, platform, and
    #     Availability Zone), and explicitly target the Capacity
    #     Reservation. This ensures that only permitted instances can use

    #   is not specified, your AWS managed CMK for EBS is used. If
    #   `KmsKeyId` is specified, the encrypted state must be `true`.
    #
    #   You can specify the CMK using any of the following:
    #
    #   * Key ID. For example, key/1234abcd-12ab-34cd-56ef-1234567890ab.
    #
    #   * Key alias. For example, alias/ExampleAlias.
    #
    #   * Key ARN. For example,
    #     arn:aws:kms:*us-east-1*\:*012345678910*\:key/*abcd1234-a123-456a-a12b-a123b4cd56ef*.
    #
    #   * Alias ARN. For example,
    #     arn:aws:kms:*us-east-1*\:*012345678910*\:alias/*ExampleAlias*.
    #
    #   AWS authenticates the CMK asynchronously. Therefore, if you specify

    #     instance.
    #
    #   * `spotFleetRequestConfigurationInvalid` - The configuration is not

    #
    #   * `spotInstanceCountLimitExceeded` - You've reached the limit on
    #     the number of Spot Instances that you can launch.
    #
    #   The following are the `fleetRequestChange` events:
    #
    #   * `active` - The EC2 Fleet or Spot Fleet request has been validated
    #     and Amazon EC2 is attempting to maintain the target number of
    #     running Spot Instances.
    #
    #   * `cancelled` - The EC2 Fleet or Spot Fleet request is canceled and
    #     has no running Spot Instances. The EC2 Fleet or Spot Fleet will be
    #     deleted two days after its instances were terminated.
    #
    #   * `cancelled_running` - The EC2 Fleet or Spot Fleet request is
    #     canceled and does not launch additional Spot Instances. Existing
    #     Spot Instances continue to run until they are interrupted or
    #     terminated.
    #
    #   * `cancelled_terminating` - The EC2 Fleet or Spot Fleet request is
    #     canceled and its Spot Instances are terminating.
    #
    #   * `expired` - The EC2 Fleet or 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 EC2 Fleet or Spot
    #     Fleet request was accepted and is in progress.
    #
    #   * `modify_successful` - The EC2 Fleet or 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 EC2 Fleet or 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:
    #
    #   * `launchSpecTemporarilyBlacklisted` - The configuration is not
    #     valid and several attempts to launch instances have failed. For
    #     more information, see the description of the event.
    #
    #   * `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.

    # @!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 AMI. 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. 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*.
    #
    #   * 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. This action will eventually report failure.
    #
    #   The specified CMK must exist in the Region that the AMI is being
    #   copied to.
    #   @return [String]
    #
    # @!attribute [rw] license_type
    #   The license type to be used for the Amazon Machine Image (AMI) after
    #   importing.
    #
    #   By default, we detect the source-system operating system (OS) and
    #   apply the appropriate license. Specify `AWS` to replace the
    #   source-system license with an AWS license, if appropriate. Specify
    #   `BYOL` to retain the source-system license, if appropriate.
    #
    #   To use `BYOL`, you must have existing licenses with rights to use
    #   these licenses in a third party cloud, such as AWS. For more
    #   information, see [Prerequisites][1] in the VM Import/Export User

    #   @return [Boolean]
    #
    # @!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 snapshot. 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. 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*.
    #
    #   * 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. This action will eventually report failure.
    #

    #   being copied to.

    #   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

    #
    #   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
