    #
    #   Default: `false`

    #   the stack will be rolled back.
    # @option options [Array<String>] :notification_arns
    #   The Simple Notification Service (SNS) topic ARNs to publish stack
    #   related events. You can find your SNS topic ARNs using the SNS console
    #   or your Command Line Interface (CLI).
    # @option options [Array<String>] :capabilities
    #   In some cases, you must explicity acknowledge that your stack template
    #   contains certain capabilities in order for AWS CloudFormation to
    #   create the stack.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your AWS account; for example, by creating new AWS
    #     Identity and Access Management (IAM) users. For those stacks, you
    #     must explicitly acknowledge this by specifying one of these
    #     capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, AWS
    #       CloudFormation returns an `InsufficientCapabilities` error.
    #
    #     If your stack template contains these resources, we recommend that
    #     you review all permissions associated with them and edit their
    #     permissions if necessary.
    #
    #     * [ AWS::IAM::AccessKey][1]
    #
    #     * [ AWS::IAM::Group][2]
    #
    #     * [ AWS::IAM::InstanceProfile][3]
    #
    #     * [ AWS::IAM::Policy][4]
    #
    #     * [ AWS::IAM::Role][5]
    #
    #     * [ AWS::IAM::User][6]
    #
    #     * [ AWS::IAM::UserToGroupAddition][7]
    #
    #     For more information, see [Acknowledging IAM Resources in AWS
    #     CloudFormation Templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some template contain macros. Macros perform custom processing on
    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually creating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     create a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][9] and
    #     [AWS::Serverless][10] transforms, which are macros hosted by AWS
    #     CloudFormation.
    #
    #     Change sets do not currently support nested stacks. If you want to
    #     create a stack from a stack template that contains macros *and*
    #     nested stacks, you must create the stack directly from the template
    #     using this capability.
    #
    #     You should only create stacks directly from a stack template that
    #     contains macros if you know what processing the macro performs.
    #
    #      Each macro relies on an underlying Lambda service function for
    #     processing stack templates. Be aware that the Lambda function owner
    #     can update the function operation without AWS CloudFormation being
    #     notified.
    #
    #     For more information, see [Using AWS CloudFormation Macros to
    #     Perform Custom Processing on Templates][11].

    # @option options [Array<String>] :resource_types
    #   The template resource types that you have permissions to work with for
    #   this create stack action, such as `AWS::EC2::Instance`, `AWS::EC2::*`,
    #   or `Custom::MyCustomInstance`. Use the following syntax to describe
    #   template resource types: `AWS::*` (for all AWS resource), `Custom::*`
    #   (for all custom resources), `Custom::logical_ID ` (for a specific
    #   custom resource), `AWS::service_name::*` (for all resources of a
    #   particular AWS service), and `AWS::service_name::resource_logical_ID `
    #   (for a specific AWS resource).
    #
    #   If the list of resource types doesn't include a resource that you're
    #   creating, the stack creation fails. By default, AWS CloudFormation
    #   grants permissions to all resource types. AWS Identity and Access
    #   Management (IAM) uses this parameter for AWS CloudFormation-specific
    #   condition keys in IAM policies. For more information, see [Controlling
    #   Access with AWS Identity and Access Management][1].
    #
    #
    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html
    # @option options [String] :role_arn
    #   The Amazon Resource Name (ARN) of an AWS Identity and Access
    #   Management (IAM) role that AWS CloudFormation assumes to create the
    #   stack. AWS CloudFormation uses the role's credentials to make calls
    #   on your behalf. AWS CloudFormation always uses this role for all
    #   future operations on the stack. As long as users have permission to
    #   operate on the stack, AWS CloudFormation uses this role even if the
    #   users don't have permission to pass it. Ensure that the role grants
    #   least privilege.
    #
    #   If you don't specify a value, AWS CloudFormation uses the role that
    #   was previously associated with the stack. If no role is available, AWS
    #   CloudFormation uses a temporary session that is generated from your
    #   user credentials.
    # @option options [String] :on_failure
    #   Determines what action will be taken if stack creation fails. This
    #   must be one of: DO\_NOTHING, ROLLBACK, or DELETE. You can specify
    #   either `OnFailure` or `DisableRollback`, but not both.
    #
    #   Default: `ROLLBACK`
    # @option options [String] :stack_policy_body
    #   Structure containing the stack policy body. For more information, go
    #   to [ Prevent Updates to Stack Resources][1] in the *AWS CloudFormation
    #   User Guide*. You can specify either the `StackPolicyBody` or the
    #   `StackPolicyURL` parameter, but not both.
    #
    #
    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html
    # @option options [String] :stack_policy_url
    #   Location of a file containing the stack policy. The URL must point to
    #   a policy (maximum size: 16 KB) located in an S3 bucket in the same
    #   region as the stack. You can specify either the `StackPolicyBody` or
    #   the `StackPolicyURL` parameter, but not both.
    # @option options [Array<Types::Tag>] :tags
    #   Key-value pairs to associate with this stack. AWS CloudFormation also
    #   propagates these tags to the resources created in the stack. A maximum
    #   number of 50 tags can be specified.
    # @option options [String] :client_request_token
    #   A unique identifier for this `CreateStack` request. Specify this token
    #   if you plan to retry requests so that AWS CloudFormation knows that
    #   you're not attempting to create a stack with the same name. You might
    #   retry `CreateStack` requests to ensure that AWS CloudFormation
    #   successfully received them.
    #
    #   All events triggered by a given stack operation are assigned the same
    #   client request token, which you can use to track operations. For
    #   example, if you execute a `CreateStack` operation with the token
    #   `token1`, then all the `StackEvents` generated by that operation will
    #   have `ClientRequestToken` set as `token1`.
    #
    #   In the console, stack operations display the client request token on
    #   the Events tab. Stack operations that are initiated from the console
    #   use the token format *Console-StackOperation-ID*, which helps you
    #   easily identify the stack operation . For example, if you create a
    #   stack using the console, each stack event would be assigned the same
    #   token in the following format:
    #   `Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.
    # @option options [Boolean] :enable_termination_protection
    #   Whether to enable termination protection on the specified stack. If a
    #   user attempts to delete a stack with termination protection enabled,
    #   the operation fails and the stack remains unchanged. For more
    #   information, see [Protecting a Stack From Being Deleted][1] in the
    #   *AWS CloudFormation User Guide*. Termination protection is disabled on
    #   stacks by default.
    #
    #   For [nested stacks][2], termination protection is set on the root
    #   stack and cannot be changed directly on the nested stack.
