    #     built-in security group with each layer (default setting). You can
    #     associate additional security groups with a layer after you create
    #     it but you cannot delete the built-in security group.
    #
    #   * False - OpsWorks Stacks does not associate built-in security
    #     groups with layers. You must create appropriate Amazon EC2
    #     security groups and associate a security group with each layer
    #     that you create. However, you can still manually associate a
    #     built-in security group with a layer on creation; custom security
    #     groups are required only for those layers that need custom
    #     settings.

    #
    #   * Fixed version - Set this parameter to your preferred agent

    #   are set to the same value, the stack uses a *regional* endpoint. If
    #   the `--stack-region` parameter is not set, but the CLI `--region`
    #   parameter is, this also results in a stack with a *regional*
    #   endpoint. However, if the `--region` parameter is set to
    #   `us-east-1`, and the `--stack-region` parameter is set to one of the
    #   following, then the stack uses a legacy or *classic* region:
    #   `us-west-1, us-west-2, sa-east-1, eu-central-1, eu-west-1,
    #   ap-northeast-1, ap-southeast-1, ap-southeast-2`. In this case, the
    #   actual API endpoint of the stack is in `us-east-1`. Only the
    #   preceding regions are supported as classic regions in the

    #   the regional endpoint that is closest to where you manage Amazon Web
    #   Services, we recommend that you use regional endpoints for new
    #   stacks. The CLI common `--region` parameter always specifies a
    #   regional API endpoint; it cannot be used to specify a classic

    #
    #   OpsWorks Stacks provides a standard set of built-in security groups,
    #   one for each layer, which are associated with layers by default.
    #   With `UseOpsworksSecurityGroups` you can instead provide your own
    #   custom security groups. `UseOpsworksSecurityGroups` has the
    #   following settings:
    #
    #   * True - OpsWorks Stacks automatically associates the appropriate
    #     built-in security group with each layer (default setting). You can
    #     associate additional security groups with a layer after you create
    #     it, but you cannot delete the built-in security group.
    #
    #   * False - OpsWorks Stacks does not associate built-in security
    #     groups with layers. You must create appropriate EC2 security
    #     groups and associate a security group with each layer that you
    #     create. However, you can still manually associate a built-in
    #     security group with a layer on creation; custom security groups
    #     are required only for those layers that need custom settings.

    #   A default Amazon EC2 key pair name. The default value is none. If
    #   you specify a key pair name, OpsWorks installs the public key on the
    #   instance and you can use the private key with an SSH client to log
    #   in to the instance. For more information, see [ Using SSH to

    #   The default OpsWorks Stacks agent version. You have the following
    #   options:
    #
    #   * Auto-update - Set this parameter to `LATEST`. OpsWorks Stacks
    #     automatically installs new agent versions on the stack's
    #     instances as soon as they are available.
    #
    #   * Fixed version - Set this parameter to your preferred agent
    #     version. To update the agent version, you must edit the stack
    #     configuration and specify a new version. OpsWorks Stacks installs
    #     that version on the stack's instances.
    #
    #   The default setting is the most recent release of the agent. To
    #   specify an agent version, you must use the complete version number,
    #   not the abbreviated number shown on the console. For a list of
    #   available agent version numbers, call DescribeAgentVersions.
    #   AgentVersion cannot be set to Chef 12.2.
    #

    #
    #   For stacks, the following commands are available:
    #
    #   * `execute_recipes`: Execute one or more recipes. To specify the
    #     recipes, set an `Args` parameter named `recipes` to the list of
    #     recipes to be executed. For example, to execute
    #     `phpapp::appsetup`, set `Args` to
    #     `{"recipes":["phpapp::appsetup"]}`.
    #
    #   * `install_dependencies`: Install the stack's dependencies.
    #
    #   * `update_custom_cookbooks`: Update the stack's custom cookbooks.
    #
    #   * `update_dependencies`: Update the stack's dependencies.
    #
    #   <note markdown="1"> The update\_dependencies and install\_dependencies commands are
    #   supported only for Linux instances. You can run the commands
    #   successfully on Windows instances, but they do nothing.
    #
    #    </note>
    #
    #   For apps, the following commands are available:
    #
    #   * `deploy`: Deploy an app. Ruby on Rails apps have an optional
    #     `Args` parameter named `migrate`. Set `Args` to
    #     \{"migrate":\["true"\]} to migrate the database. The default
    #     setting is \{"migrate":\["false"\]}.
    #
    #   * `rollback` Roll the app back to the previous version. When you
    #     update an app, OpsWorks Stacks stores the previous version, up to
    #     a maximum of five versions. You can use this command to roll an
    #     app back as many as four versions.
    #
    #   * `start`: Start the app's web or application server.
    #
    #   * `stop`: Stop the app's web or application server.
    #
    #   * `restart`: Restart the app's web or application server.
    #
    #   * `undeploy`: Undeploy the app.

    #
    # @!attribute [rw] args
    #   The arguments of those commands that take arguments. It should be

    #   `{"arg_name1" : ["value1", "value2", ...], "arg_name2" : ["value1",
    #   "value2", ...], ...}`
    #
    #   The `update_dependencies` command takes two arguments:
    #
    #   * `upgrade_os_to` - Specifies the Amazon Linux version that you want
    #     instances to run, such as `Amazon Linux 2`. You must also set the
    #     `allow_reboot` argument to true.
    #
    #   * `allow_reboot` - Specifies whether to allow OpsWorks Stacks to
    #     reboot the instances if necessary, after installing the updates.
    #     This argument can be set to either `true` or `false`. The default
    #     value is `false`.
    #
    #   For example, to upgrade an instance to Amazon Linux 2018.03, set

    #   Whether to associate the OpsWorks Stacks built-in security groups
    #   with the stack's layers.
    #
    #   OpsWorks Stacks provides a standard set of built-in security groups,
    #   one for each layer, which are associated with layers by default.
    #   `UseOpsworksSecurityGroups` allows you to provide your own custom
    #   security groups instead of using the built-in groups.
    #   `UseOpsworksSecurityGroups` has the following settings:
    #
    #   * True - OpsWorks Stacks automatically associates the appropriate
    #     built-in security group with each layer (default setting). You can
    #     associate additional security groups with a layer after you create
    #     it, but you cannot delete the built-in security group.
    #
    #   * False - OpsWorks Stacks does not associate built-in security
    #     groups with layers. You must create appropriate EC2 security
    #     groups and associate a security group with each layer that you
    #     create. However, you can still manually associate a built-in
    #     security group with a layer on. Custom security groups are
    #     required only for those layers that need custom settings.

    # @!attribute [rw] agent_version
    #   The default OpsWorks Stacks agent version. You have the following
    #   options:
    #
    #   * Auto-update - Set this parameter to `LATEST`. OpsWorks Stacks
    #     automatically installs new agent versions on the stack's
    #     instances as soon as they are available.
    #
    #   * Fixed version - Set this parameter to your preferred agent
    #     version. To update the agent version, you must edit the stack
    #     configuration and specify a new version. OpsWorks Stacks installs
    #     that version on the stack's instances.
    #
    #   The default setting is `LATEST`. To specify an agent version, you
    #   must use the complete version number, not the abbreviated number
    #   shown on the console. For a list of available agent version numbers,
    #   call DescribeAgentVersions. AgentVersion cannot be set to Chef 12.2.
    #
