#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - SourceStackId => (string)

    The source stack ID.

  - Name => (string)

    The cloned stack name.

  - Region => (string)

    The cloned stack AWS region, such as "us-east-1". For more information about AWS regions, see Regions and Endpoints.

  - VpcId => (string)

    The ID of the VPC that the cloned stack is to be launched into. It must be in the specified region. All instances are launched into this VPC, and you cannot change the ID later.

    - If your account supports EC2 Classic, the default value is no VPC.
    - If your account does not support EC2 Classic, the default value is the default VPC for the specified region.

    If the VPC ID corresponds to a default VPC and you have specified either the DefaultAvailabilityZone or the DefaultSubnetId parameter only, AWS OpsWorks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks sets these parameters to the first valid Availability Zone for the specified region and the corresponding default VPC subnet ID, respectively.

    If you specify a nondefault VPC ID, note the following:

    - It must belong to a VPC in your account that is in the specified region.
    - You must specify a value for DefaultSubnetId.

    For more information on how to use AWS OpsWorks with a VPC, see Running a Stack in a VPC. For more information on default VPC and EC2 Classic, see Supported Platforms.

  - Attributes => (associative-array<string>)

    Associative array of <StackAttributesKeys> keys mapping to (string) values. Each array key should be changed to an appropriate <StackAttributesKeys>.

    A list of stack attributes and values as key/value pairs to be added to the cloned stack.

    - <StackAttributesKeys> => (string)
  - ServiceRoleArn => (string)

    The stack AWS Identity and Access Management (IAM) role, which allows AWS OpsWorks to work with AWS resources on your behalf. You must set this parameter to the Amazon Resource Name (ARN) for an existing IAM role. If you create a stack by using the AWS OpsWorks console, it creates the role for you. You can obtain an existing stack's IAM ARN programmatically by calling DescribePermissions. For more information about IAM ARNs, see Using Identifiers.

    You must set this parameter to a valid service role ARN or the action will fail; there is no default value. You can specify the source stack's service role ARN, if you prefer, but you must do so explicitly.

  - DefaultInstanceProfileArn => (string)

    The Amazon Resource Name (ARN) of an IAM profile that is the default profile for all of the stack's EC2 instances. For more information about IAM ARNs, see Using Identifiers.

  - DefaultOs => (string)

    The stack's operating system, which must be set to one of the following.

    - A supported Linux operating system: An Amazon Linux version, such as Amazon Linux 2015.03, Red Hat Enterprise Linux 7, Ubuntu 12.04 LTS, or Ubuntu 14.04 LTS.
    - Microsoft Windows Server 2012 R2 Base.
    - A custom AMI: Custom. You specify the custom AMI you want to use when you create instances. For more information on how to use custom AMIs with OpsWorks, see Using Custom AMIs.

    The default option is the parent stack's operating system. For more information on the supported operating systems, see AWS OpsWorks Operating Systems.

    You can specify a different Linux operating system for the cloned stack, but you cannot change from Linux to Windows or Windows to Linux.
  - HostnameTheme => (string)

    The stack's host name theme, with spaces are replaced by underscores. The theme is used to generate host names for the stack's instances. By default, HostnameTheme is set to Layer_Dependent, which creates host names by appending integers to the layer's short name. The other themes are:

    - Baked_Goods
    - Clouds
    - Europe_Cities
    - Fruits
    - Greek_Deities
    - Legendary_creatures_from_Japan
    - Planets_and_Moons
    - Roman_Deities
    - Scottish_Islands
    - US_Cities
    - Wild_Cats

    To obtain a generated host name, call GetHostNameSuggestion, which returns a host name based on the current theme.

  - DefaultAvailabilityZone => (string)

    The cloned stack's default Availability Zone, which must be in the specified region. For more information, see Regions and Endpoints. If you also specify a value for DefaultSubnetId, the subnet must be in the same zone. For more information, see the VpcId parameter description.

  - DefaultSubnetId => (string)

    The stack's default VPC subnet ID. This parameter is required if you specify a value for the VpcId parameter. All instances are launched into this subnet unless you specify otherwise when you create the instance. If you also specify a value for DefaultAvailabilityZone, the subnet must be in that zone. For information on default values and when this parameter is required, see the VpcId parameter description.

  - CustomJson => (string)

    A string that contains user-defined, custom JSON. It is used to override the corresponding default stack configuration JSON values. The string should be in the following format and must escape characters such as '"':

    "{\"key1\": \"value1\", \"key2\": \"value2\",...}"

    For more information on custom JSON, see Use Custom JSON to Modify the Stack Configuration Attributes

  - ConfigurationManager => (associative-array)

    The configuration manager. When you clone a Linux stack we recommend that you use the configuration manager to specify the Chef version: 0.9, 11.4, or 11.10. The default value is currently 11.10.

    - Name => (string)

      The name. This parameter must be set to "Chef".

    - Version => (string)

      The Chef version. This parameter must be set to 0.9, 11.4, or 11.10. The default value is 11.4.

  - ChefConfiguration => (associative-array)

    A ChefConfiguration object that specifies whether to enable Berkshelf and the Berkshelf version on Chef 11.10 stacks. For more information, see Create a New Stack.

    - ManageBerkshelf => (bool)

      Whether to enable Berkshelf.

    - BerkshelfVersion => (string)

      The Berkshelf version.

  - UseCustomCookbooks => (bool)

    Whether to use custom cookbooks.

  - UseOpsworksSecurityGroups => (bool)

    Whether to associate the AWS OpsWorks built-in security groups with the stack's layers.

    AWS OpsWorks 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 - AWS OpsWorks 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 - AWS OpsWorks does not associate built-in security groups with layers. You must create appropriate Amazon Elastic Compute Cloud (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.

    For more information, see Create a New Stack.

  - CustomCookbooksSource => (associative-array)

    Contains the information required to retrieve an app or cookbook from a repository. For more information, see Creating Apps or Custom Recipes and Cookbooks.

    - Type => (string: git | svn | archive | s3 )

      The repository type.

    - Url => (string)

      The source URL.

    - Username => (string)

      This parameter depends on the repository type.

      - For Amazon S3 bundles, set Username to the appropriate IAM access key ID.
      - For HTTP bundles, Git repositories, and Subversion repositories, set Username to the user name.
    - Password => (string)

      When included in a request, the parameter depends on the repository type.

      - For Amazon S3 bundles, set Password to the appropriate IAM secret access key.
      - For HTTP bundles and Subversion repositories, set Password to the password.

      For more information on how to safely handle IAM credentials, see .

      In responses, AWS OpsWorks returns *****FILTERED***** instead of the actual value.

    - SshKey => (string)

      In requests, the repository's SSH key.

      In responses, AWS OpsWorks returns *****FILTERED***** instead of the actual value.

    - Revision => (string)

      The application's version. AWS OpsWorks enables you to easily deploy new versions of an application. One of the simplest approaches is to have branches or revisions in your repository that represent different versions that can potentially be deployed.

  - DefaultSshKeyName => (string)

    A default Amazon EC2 key pair name. The default value is none. If you specify a key pair name, AWS 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 Communicate with an Instance and Managing SSH Access. You can override this setting by specifying a different key pair, or no key pair, when you create an instance.

  - ClonePermissions => (bool)

    Whether to clone the source stack's permissions.

  - CloneAppIds => (array<string>)

    A list of source stack app IDs to be included in the cloned stack.

  - DefaultRootDeviceType => (string: ebs | instance-store )

    The default root device type. This value is used by default for all instances in the cloned stack, but you can override it when you create an instance. For more information, see Storage for the Root Device.

  - AgentVersion => (string)

    The default AWS OpsWorks agent version. You have the following options:

    - Auto-update - Set this parameter to LATEST. AWS OpsWorks 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. AWS OpsWorks then automatically 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.

    You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- StackId => (string)

  The cloned stack ID.

# `public `Guzzle\Service\Resource\Model``
`createApp( array $args = array() )`

Executes the CreateApp operation.

Creates an app for a specified stack. For more information, see Creating Apps.

Required Permissions: To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see Managing User Permissions.

    There is no specific limit on the number of environment variables. However, the size of the associated data structure - which includes the variables' names, values, and protected flag values - cannot exceed 10 KB (10240 Bytes). This limit should accommodate most if not all use cases. Exceeding it will cause an exception with the message, "Environment: is too large (maximum is 10KB)."

    This parameter is supported only by Chef 11.10 stacks. If you have specified one or more environment variables, you cannot modify the stack's Chef version.
    - (associative-array)

      Represents an app's environment variable.

      - Key => (string)

        (Required) The environment variable's name, which can consist of up to 64 characters and must be specified. The name can contain upper- and lowercase letters, numbers, and underscores (_), but it must start with a letter or underscore.

  - InstallUpdatesOnBoot => (bool)

    Whether to install operating system and package updates when the instance boots. The default value is true. To control when updates are installed, set this value to false. You must then update your instances manually by using CreateDeployment to run the update_dependencies stack command or by manually running yum (Amazon Linux) or apt-get (Ubuntu) on the instances.

    We strongly recommend using the default value of true to ensure that your instances have the latest security updates.

  - EbsOptimized => (bool)

    Whether to create an Amazon EBS-optimized instance.

  - AgentVersion => (string)

    The default AWS OpsWorks agent version. You have the following options:

    - version_number - Use the specified agent version. This value overrides the stack's default setting. To update the agent version, edit the instance configuration and specify a new version. AWS OpsWorks then automatically installs that version on the instance.

    The default setting is INHERIT. 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.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- InstanceId => (string)

  The instance ID.

You should use CreateLayer for noncustom layer types such as PHP App Server only if the stack does not have an existing layer of that type. A stack can have at most one instance of each noncustom layer; if you attempt to create a second instance, CreateLayer fails. A stack can have an arbitrary number of custom layers, so you can call CreateLayer as many times as you like for that layer type.

Required Permissions: To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see Managing User Permissions.

  $arg Associative array containing the following keys (required keys are bold):
  - Name => (string)

    The stack name.

  - Region => (string)

    The stack's AWS region, such as "us-east-1". For more information about Amazon regions, see Regions and Endpoints.

  - VpcId => (string)

    The ID of the VPC that the stack is to be launched into. The VPC must be in the stack's region. All instances are launched into this VPC. You cannot change the ID later.

    - If your account supports EC2-Classic, the default value is no VPC.
    - If your account does not support EC2-Classic, the default value is the default VPC for the specified region.

    If the VPC ID corresponds to a default VPC and you have specified either the DefaultAvailabilityZone or the DefaultSubnetId parameter only, AWS OpsWorks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks sets these parameters to the first valid Availability Zone for the specified region and the corresponding default VPC subnet ID, respectively.

    If you specify a nondefault VPC ID, note the following:

    - It must belong to a VPC in your account that is in the specified region.
    - You must specify a value for DefaultSubnetId.

    For more information on how to use AWS OpsWorks with a VPC, see Running a Stack in a VPC. For more information on default VPC and EC2-Classic, see Supported Platforms.

    The stack's AWS Identity and Access Management (IAM) role, which allows AWS OpsWorks to work with AWS resources on your behalf. You must set this parameter to the Amazon Resource Name (ARN) for an existing IAM role. For more information about IAM ARNs, see Using Identifiers.

  - DefaultInstanceProfileArn => (string)

    The Amazon Resource Name (ARN) of an IAM profile that is the default profile for all of the stack's EC2 instances. For more information about IAM ARNs, see Using Identifiers.

  - DefaultOs => (string)

    The stack's default operating system, which is installed on every instance unless you specify a different operating system when you create the instance. You can specify one of the following.

    - A supported Linux operating system: An Amazon Linux version, such as Amazon Linux 2015.03, Red Hat Enterprise Linux 7, Ubuntu 12.04 LTS, or Ubuntu 14.04 LTS.
    - Microsoft Windows Server 2012 R2 Base.
    - A custom AMI: Custom. You specify the custom AMI you want to use when you create instances. For more information, see Using Custom AMIs.

    The default option is the current Amazon Linux version. For more information on the supported operating systems, see AWS OpsWorks Operating Systems.

  - HostnameTheme => (string)

    The stack's host name theme, with spaces replaced by underscores. The theme is used to generate host names for the stack's instances. By default, HostnameTheme is set to Layer_Dependent, which creates host names by appending integers to the layer's short name. The other themes are:

    - Baked_Goods

  - DefaultSubnetId => (string)

    The stack's default VPC subnet ID. This parameter is required if you specify a value for the VpcId parameter. All instances are launched into this subnet unless you specify otherwise when you create the instance. If you also specify a value for DefaultAvailabilityZone, the subnet must be in that zone. For information on default values and when this parameter is required, see the VpcId parameter description.

  - CustomJson => (string)

    A string that contains user-defined, custom JSON. It can be used to override the corresponding default stack configuration attribute values or to pass data to recipes. The string should be in the following escape characters such as '"':

  - UseOpsworksSecurityGroups => (bool)

    Whether to associate the AWS OpsWorks built-in security groups with the stack's layers.

    AWS OpsWorks 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 - AWS OpsWorks 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 - AWS OpsWorks 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.

    For more information, see Create a New Stack.

  - CustomCookbooksSource => (associative-array)

    Contains the information required to retrieve an app or cookbook from a repository. For more information, see Creating Apps or Custom Recipes and Cookbooks.

    - Type => (string: git | svn | archive | s3 )

      The repository type.

    - Url => (string)

      The source URL.

    - Username => (string)

      This parameter depends on the repository type.

      - For Amazon S3 bundles, set Username to the appropriate IAM access key ID.
      - For HTTP bundles, Git repositories, and Subversion repositories, set Username to the user name.
    - Password => (string)

      When included in a request, the parameter depends on the repository type.

      - For Amazon S3 bundles, set Password to the appropriate IAM secret access key.
      - For HTTP bundles and Subversion repositories, set Password to the password.

      For more information on how to safely handle IAM credentials, see .

      In responses, AWS OpsWorks returns *****FILTERED***** instead of the actual value.

    - SshKey => (string)

      In requests, the repository's SSH key.

      In responses, AWS OpsWorks returns *****FILTERED***** instead of the actual value.

    - Revision => (string)

      The application's version. AWS OpsWorks enables you to easily deploy new versions of an application. One of the simplest approaches is to have branches or revisions in your repository that represent different versions that can potentially be deployed.

  - DefaultSshKeyName => (string)

    A default Amazon EC2 key pair name. The default value is none. If you specify a key pair name, AWS 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 Communicate with an Instance and Managing SSH Access. You can override this setting by specifying a different key pair, or no key pair, when you create an instance.

  - DefaultRootDeviceType => (string: ebs | instance-store )

    The default root device type. This value is the default for all instances in the stack, but you can override it when you create an instance. The default option is instance-store. For more information, see Storage for the Root Device.

  - AgentVersion => (string)

    The default AWS OpsWorks agent version. You have the following options:

    - Auto-update - Set this parameter to LATEST. AWS OpsWorks 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. AWS OpsWorks then automatically 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.

    You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.

  The volume ID.

# `public `Guzzle\Service\Resource\Model``
`setLoadBasedAutoScaling( array $args = array() )`

Executes the SetLoadBasedAutoScaling operation.

Specify the load-based auto scaling configuration for a specified layer. For more information, see Managing Load with Time-based and Load-based Instances.

To use load-based auto scaling, you must create a set of load-based auto scaling instances. Load-based auto scaling operates only on the instances from that set, so you must ensure that you have created enough instances to handle the maximum anticipated load.

Required Permissions: To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see Managing User Permissions.

#### Examples

- Basic formatting example

      $result = $client->setLoadBasedAutoScaling(array(
          // LayerId is required
          'LayerId' => 'string',
          'Enable' => true || false,
          'UpScaling' => array(
              'InstanceCount' => integer,
              'ThresholdsWaitTime' => integer,
              'IgnoreMetricsTime' => integer,
              'CpuThreshold' => integer,

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - LayerId => (string)

    The layer ID.

  - Enable => (bool)

    Enables load-based auto scaling for the layer.

  - UpScaling => (associative-array)

    An AutoScalingThresholds object with the upscaling threshold configuration. If the load exceeds these thresholds for a specified amount of time, AWS OpsWorks starts a specified number of instances.

    - InstanceCount => (int)

      The number of instances to add or remove when the load exceeds a threshold.

    - ThresholdsWaitTime => (int)

      The amount of time, in minutes, that the load must exceed a threshold before more instances are added or removed.

    - IgnoreMetricsTime => (int)

      The amount of time (in minutes) after a scaling event occurs that AWS OpsWorks should ignore metrics and suppress additional scaling events. For example, AWS OpsWorks adds new instances following an upscaling event but the instances won't start reducing the load until they have been booted and configured. There is no point in raising additional scaling events during that operation, which typically takes several minutes. IgnoreMetricsTime allows you to direct AWS OpsWorks to suppress scaling events long enough to get the new instances online.

    - CpuThreshold => (int)

      The CPU utilization threshold, as a percent of the available CPU.

    - MemoryThreshold => (int)

      The memory utilization threshold, as a percent of the available memory.

    - LoadThreshold => (int)

      The load threshold. For more information about how load is computed, see Load (computing).

    - Alarms => (array<string>)

      Custom Cloudwatch auto scaling alarms, to be used as thresholds. This parameter takes a list of up to five alarm names, which are case sensitive and must be in the same region as the stack.

      To use custom alarms, you must update your service role to allow cloudwatch:DescribeAlarms. You can either have AWS OpsWorks update the role for you when you first use this feature or you can edit the role manually. For more information, see Allowing AWS OpsWorks to Act on Your Behalf.
  - DownScaling => (associative-array)

    An AutoScalingThresholds object with the downscaling threshold configuration. If the load falls below these thresholds for a specified amount of time, AWS OpsWorks stops a specified number of instances.

    - InstanceCount => (int)

      The number of instances to add or remove when the load exceeds a threshold.

    - ThresholdsWaitTime => (int)

      The amount of time, in minutes, that the load must exceed a threshold before more instances are added or removed.

    - IgnoreMetricsTime => (int)

      The amount of time (in minutes) after a scaling event occurs that AWS OpsWorks should ignore metrics and suppress additional scaling events. For example, AWS OpsWorks adds new instances following an upscaling event but the instances won't start reducing the load until they have been booted and configured. There is no point in raising additional scaling events during that operation, which typically takes several minutes. IgnoreMetricsTime allows you to direct AWS OpsWorks to suppress scaling events long enough to get the new instances online.

    - CpuThreshold => (int)

      The CPU utilization threshold, as a percent of the available CPU.

    - MemoryThreshold => (int)

      The memory utilization threshold, as a percent of the available memory.

    - LoadThreshold => (int)

      The load threshold. For more information about how load is computed, see Load (computing).

    - Alarms => (array<string>)

      Custom Cloudwatch auto scaling alarms, to be used as thresholds. This parameter takes a list of up to five alarm names, which are case sensitive and must be in the same region as the stack.

      To use custom alarms, you must update your service role to allow cloudwatch:DescribeAlarms. You can either have AWS OpsWorks update the role for you when you first use this feature or you can edit the role manually. For more information, see Allowing AWS OpsWorks to Act on Your Behalf.

  - UseOpsworksSecurityGroups => (bool)

    Whether to associate the AWS OpsWorks built-in security groups with the stack's layers.

    AWS OpsWorks 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 - AWS OpsWorks 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 - AWS OpsWorks 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.

    For more information, see Create a New Stack.

  - AgentVersion => (string)

    The default AWS OpsWorks agent version. You have the following options:

    - Auto-update - Set this parameter to LATEST. AWS OpsWorks 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. AWS OpsWorks then automatically 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.

    You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.
