[REQUIRED]
The source stack ID.
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 the VPC ID corresponds to a default VPC and you have specified either the DefaultAvailabilityZone or the DefaultSubnetId parameter only, AWS OpsWorks Stacks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks Stacks 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:
For more information about how to use AWS OpsWorks Stacks with a VPC, see Running a Stack in a VPC . For more information about default VPC and EC2 Classic, see Supported Platforms .
A list of stack attributes and values as key/value pairs to be added to the cloned stack.
[REQUIRED]
The stack AWS Identity and Access Management (IAM) role, which allows AWS OpsWorks Stacks 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 Stacks 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 .
Note
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.
The stack's operating system, which must be set to one of the following.
The default option is the parent stack's operating system. For more information about supported operating systems, see AWS OpsWorks Stacks Operating Systems .
Note
You can specify a different Linux operating system for the cloned stack, but you cannot change from Linux to Windows or Windows to Linux.
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:
To obtain a generated host name, call GetHostNameSuggestion , which returns a host name based on the current theme.
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:
"{\"key1\": \"value1\", \"key2\": \"value2\",...}"
For more information about custom JSON, see Use Custom JSON to Modify the Stack Configuration Attributes
The configuration manager. When you clone a stack we recommend that you use the configuration manager to specify the Chef version: 12, 11.10, or 11.4 for Linux stacks, or 12.2 for Windows stacks. The default value for Linux stacks is currently 12.
The name. This parameter must be set to "Chef".
The Chef version. This parameter must be set to 12, 11.10, or 11.4 for Linux stacks, and to 12.2 for Windows stacks. The default value for Linux stacks is 11.4.
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 .
Whether to enable Berkshelf.
The Berkshelf version.
Whether to associate the AWS OpsWorks Stacks built-in security groups with the stack's layers.
AWS 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:
For more information, see Create a New Stack .
Contains the information required to retrieve an app or cookbook from a repository. For more information, see Adding Apps or Cookbooks and Recipes .

The parameter values that you use to specify the various types are in the API Name column of the Available Instance Types table.
The instance's operating system, which must be set to one of the following.
For more information about the supported operating systems, see AWS OpsWorks Stacks Operating Systems .
The default option is the current Amazon Linux version. If you set this parameter to Custom , you must use the CreateInstance action's AmiId parameter to specify the custom AMI that you want to use. Block device mappings are not supported if the value is Custom . For more information about supported operating systems, see Operating Systems For more information about how to use custom AMIs with AWS OpsWorks Stacks, see Using Custom AMIs .
A custom AMI ID to be used to create the instance. The AMI should be based on one of the supported operating systems. For more information, see Using Custom AMIs .
Note
If you specify a custom AMI, you must set Os to Custom .
An array of BlockDeviceMapping objects that specify the instance's block devices. For more information, see Block Device Mapping . Note that block device mappings are not supported for custom AMIs.
Describes a block device mapping. This data type maps directly to the Amazon EC2 BlockDeviceMapping data type.

If you specify the io1 volume type, you must also specify a value for the Iops attribute. The maximum ratio of provisioned IOPS to requested volume size (in GiB) is 50:1. AWS uses the default volume size (in GiB) specified in the AMI attributes to set IOPS to 50 x (volume size).
Whether the volume is deleted on instance termination.
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.
Note
We strongly recommend using the default value of true to ensure that your instances have the latest security updates.
The default AWS OpsWorks Stacks agent version. You have the following options:
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 . AgentVersion cannot be set to Chef 12.2.

Creates a layer. For more information, see How to Create a Layer .
Note
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]
The layer stack ID.
[REQUIRED]
The layer type. A stack cannot have more than one built-in layer of the same type. It can have any number of custom layers. Built-in layers are not available in Chef 12 stacks.
[REQUIRED]
The layer name, which is used by the console.
[REQUIRED]
For custom layers only, use this parameter to specify the layer's short name, which is used internally by AWS OpsWorks Stacks and by Chef recipes. The short name is also used as the name for the directory where your app files are installed. It can have a maximum of 200 characters, which are limited to the alphanumeric characters, '-', '_', and '.'.
The built-in layers' short names are defined by AWS OpsWorks Stacks. For more information, see the Layer Reference .
One or more user-defined key-value pairs to be added to the stack attributes.
To create a cluster layer, set the EcsClusterArn attribute to the cluster's ARN.
Specifies CloudWatch Logs configuration options for the layer. For more information, see CloudWatchLogsLogStream .
Whether CloudWatch Logs is enabled for a layer.
A list of configuration options for CloudWatch Logs.
Describes the Amazon CloudWatch logs configuration for a layer. For detailed information about members of this data type, see the CloudWatch Logs Agent Reference .
Specifies the destination log group. A log group is created automatically if it doesn't already exist. Log group names can be between 1 and 512 characters long. Allowed characters include a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.' (period).
Specifies how the time stamp is extracted from logs. For more information, see the CloudWatch Logs Agent Reference .
Specifies the time zone of log event time stamps.
Specifies log files that you want to push to CloudWatch Logs.
File can point to a specific file or multiple files (by using wild card characters such as /var/log/system.log* ). Only the latest file is pushed to CloudWatch Logs, based on file modification time. We recommend that you use wild card characters to specify a series of files of the same type, such as access_log.2014-06-01-01 , access_log.2014-06-01-02 , and so on by using a pattern like access_log.* . Don't use a wildcard to match multiple file types, such as access_log_80 and access_log_443 . To specify multiple, different file types, add another log stream entry to the configuration file, so that each log file type is stored in a different log group.
Zipped files are not supported.
Specifies the range of lines for identifying a file. The valid values are one number, or two dash-delimited numbers, such as '1', '2-5'. The default value is '1', meaning the first line is used to calculate the fingerprint. Fingerprint lines are not sent to CloudWatch Logs unless all specified lines are available.
Specifies the pattern for identifying the start of a log message.
Specifies where to start to read data (start_of_file or end_of_file). The default is start_of_file. This setting is only used if there is no state persisted for that log stream.
Specifies the encoding of the log file so that the file can be read correctly. The default is utf_8 . Encodings supported by Python codecs.decode() can be used here.
Specifies the time duration for the batching of log events. The minimum value is 5000ms and default value is 5000ms.
Specifies the max number of log events in a batch, up to 10000. The default value is 1000.
Specifies the maximum size of log events in a batch, in bytes, up to 1048576 bytes. The default value is 32768 bytes. This size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.
An array containing the layer custom security group IDs.
An array of Package objects that describes the layer packages.
A VolumeConfigurations object that describes the layer's Amazon EBS volumes.
Describes an Amazon EBS volume configuration.
The volume mount point. For example "/dev/sdh".
The volume RAID level .
The number of disks in the volume.
The volume size.
The volume type. For more information, see Amazon EBS Volume Types .
For PIOPS volumes, the IOPS per disk.
Specifies whether an Amazon EBS volume is encrypted. For more information, see Amazon EBS Encryption .

An array of custom recipe names to be run following a setup event.
An array of custom recipe names to be run following a configure event.
An array of custom recipe names to be run following a deploy event.
An array of custom recipe names to be run following a undeploy event.
An array of custom recipe names to be run following a shutdown event.
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.
Note
To ensure that your instances have the latest security updates, we strongly recommend using the default value of true .

[REQUIRED]
The stack name.
[REQUIRED]
The stack's AWS region, such as ap-south-1 . For more information about Amazon regions, see Regions and Endpoints .
Note
In the AWS CLI, this API maps to the --stack-region parameter. If the --stack-region parameter and the AWS CLI common parameter --region are set to the same value, the stack uses a regional endpoint. If the --stack-region parameter is not set, but the AWS 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 us-east-1 API endpoint. Because it is a best practice to choose the regional endpoint that is closest to where you manage AWS, we recommend that you use regional endpoints for new stacks. The AWS CLI common --region parameter always specifies a regional API endpoint; it cannot be used to specify a classic AWS OpsWorks Stacks region.
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 the VPC ID corresponds to a default VPC and you have specified either the DefaultAvailabilityZone or the DefaultSubnetId parameter only, AWS OpsWorks Stacks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks Stacks 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:
For more information about how to use AWS OpsWorks Stacks with a VPC, see Running a Stack in a VPC . For more information about default VPC and EC2-Classic, see Supported Platforms .
One or more user-defined key-value pairs to be added to the stack attributes.
[REQUIRED]
The stack's AWS Identity and Access Management (IAM) role, which allows AWS OpsWorks Stacks 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 .
[REQUIRED]
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 .
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.
The default option is the current Amazon Linux version. For more information about supported operating systems, see AWS OpsWorks Stacks Operating Systems .
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:
To obtain a generated host name, call GetHostNameSuggestion , which returns a host name based on the current theme.
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 format:
"{\"key1\": \"value1\", \"key2\": \"value2\",...}"
For more information about custom JSON, see Use Custom JSON to Modify the Stack Configuration Attributes .
The configuration manager. When you create a stack we recommend that you use the configuration manager to specify the Chef version: 12, 11.10, or 11.4 for Linux stacks, or 12.2 for Windows stacks. The default value for Linux stacks is currently 12.
The name. This parameter must be set to "Chef".
The Chef version. This parameter must be set to 12, 11.10, or 11.4 for Linux stacks, and to 12.2 for Windows stacks. The default value for Linux stacks is 11.4.
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 .
Whether to enable Berkshelf.
The Berkshelf version.
Whether to associate the AWS OpsWorks Stacks built-in security groups with the stack's layers.
AWS 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:
For more information, see Create a New Stack .
Contains the information required to retrieve an app or cookbook from a repository. For more information, see Adding Apps or Cookbooks and Recipes .
The repository type.
The source URL. The following is an example of an Amazon S3 source URL: https://s3.amazonaws.com/opsworks-demo-bucket/opsworks_cookbook_demo.tar.gz .
This parameter depends on the repository type.
When included in a request, the parameter depends on the repository type.
For more information on how to safely handle IAM credentials, see https://docs.aws.amazon.com/general/latest/gr/aws-access-keys-best-practices.html .
In responses, AWS OpsWorks Stacks returns *****FILTERED***** instead of the actual value.
In requests, the repository's SSH key.
In responses, AWS OpsWorks Stacks returns *****FILTERED***** instead of the actual value.
The application's version. AWS OpsWorks Stacks 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.
The default AWS OpsWorks Stacks agent version. You have the following options:
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.
Note
You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.

(dict) --
Describes the Amazon CloudWatch logs configuration for a layer. For detailed information about members of this data type, see the CloudWatch Logs Agent Reference .
LogGroupName (string) --
Specifies the destination log group. A log group is created automatically if it doesn't already exist. Log group names can be between 1 and 512 characters long. Allowed characters include a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.' (period).
DatetimeFormat (string) --

TimeZone (string) --
Specifies the time zone of log event time stamps.
File (string) --
Specifies log files that you want to push to CloudWatch Logs.
File can point to a specific file or multiple files (by using wild card characters such as /var/log/system.log* ). Only the latest file is pushed to CloudWatch Logs, based on file modification time. We recommend that you use wild card characters to specify a series of files of the same type, such as access_log.2014-06-01-01 , access_log.2014-06-01-02 , and so on by using a pattern like access_log.* . Don't use a wildcard to match multiple file types, such as access_log_80 and access_log_443 . To specify multiple, different file types, add another log stream entry to the configuration file, so that each log file type is stored in a different log group.
Zipped files are not supported.
FileFingerprintLines (string) --
Specifies the range of lines for identifying a file. The valid values are one number, or two dash-delimited numbers, such as '1', '2-5'. The default value is '1', meaning the first line is used to calculate the fingerprint. Fingerprint lines are not sent to CloudWatch Logs unless all specified lines are available.

Encoding (string) --
Specifies the encoding of the log file so that the file can be read correctly. The default is utf_8 . Encodings supported by Python codecs.decode() can be used here.
BufferDuration (integer) --
Specifies the time duration for the batching of log events. The minimum value is 5000ms and default value is 5000ms.

Registers instances that were created outside of AWS OpsWorks Stacks with a specified stack.
Note
We do not recommend using this action to register instances. The complete registration operation includes two tasks: installing the AWS OpsWorks Stacks agent on the instance, and registering the instance with the stack. RegisterInstance handles only the second step. You should instead use the AWS CLI register command, which performs the entire registration operation. For more information, see Registering an Instance with an AWS OpsWorks Stacks Stack .
Registered instances have the same requirements as instances that are created by using the CreateInstance API. For example, registered instances must be running a supported Linux-based operating system, and they must have a supported instance type. For more information about requirements for instances that you want to register, see Preparing the Instance .

Note
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.

An AutoScalingThresholds object with the upscaling threshold configuration. If the load exceeds these thresholds for a specified amount of time, AWS OpsWorks Stacks starts a specified number of instances.
The number of instances to add or remove when the load exceeds a threshold.
The amount of time, in minutes, that the load must exceed a threshold before more instances are added or removed.
The amount of time (in minutes) after a scaling event occurs that AWS OpsWorks Stacks should ignore metrics and suppress additional scaling events. For example, AWS OpsWorks Stacks 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 Stacks to suppress scaling events long enough to get the new instances online.

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.
Note
To use custom alarms, you must update your service role to allow cloudwatch:DescribeAlarms . You can either have AWS OpsWorks Stacks 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 Stacks to Act on Your Behalf .
An AutoScalingThresholds object with the downscaling threshold configuration. If the load falls below these thresholds for a specified amount of time, AWS OpsWorks Stacks stops a specified number of instances.
The number of instances to add or remove when the load exceeds a threshold.
The amount of time, in minutes, that the load must exceed a threshold before more instances are added or removed.
The amount of time (in minutes) after a scaling event occurs that AWS OpsWorks Stacks should ignore metrics and suppress additional scaling events. For example, AWS OpsWorks Stacks 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 Stacks to suppress scaling events long enough to get the new instances online.

[REQUIRED]
The layer ID.
For custom layers only, use this parameter to specify the layer's short name, which is used internally by AWS OpsWorks Stacks and by Chef. The short name is also used as the name for the directory where your app files are installed. It can have a maximum of 200 characters and must be in the following format: /A[a-z0-9-_.]+Z/.
The built-in layers' short names are defined by AWS OpsWorks Stacks. For more information, see the Layer Reference
One or more user-defined key/value pairs to be added to the stack attributes.
Specifies CloudWatch Logs configuration options for the layer. For more information, see CloudWatchLogsLogStream .
Whether CloudWatch Logs is enabled for a layer.
A list of configuration options for CloudWatch Logs.
Describes the Amazon CloudWatch logs configuration for a layer. For detailed information about members of this data type, see the CloudWatch Logs Agent Reference .
Specifies the destination log group. A log group is created automatically if it doesn't already exist. Log group names can be between 1 and 512 characters long. Allowed characters include a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.' (period).
Specifies how the time stamp is extracted from logs. For more information, see the CloudWatch Logs Agent Reference .
Specifies the time zone of log event time stamps.
Specifies log files that you want to push to CloudWatch Logs.
File can point to a specific file or multiple files (by using wild card characters such as /var/log/system.log* ). Only the latest file is pushed to CloudWatch Logs, based on file modification time. We recommend that you use wild card characters to specify a series of files of the same type, such as access_log.2014-06-01-01 , access_log.2014-06-01-02 , and so on by using a pattern like access_log.* . Don't use a wildcard to match multiple file types, such as access_log_80 and access_log_443 . To specify multiple, different file types, add another log stream entry to the configuration file, so that each log file type is stored in a different log group.
Zipped files are not supported.
Specifies the range of lines for identifying a file. The valid values are one number, or two dash-delimited numbers, such as '1', '2-5'. The default value is '1', meaning the first line is used to calculate the fingerprint. Fingerprint lines are not sent to CloudWatch Logs unless all specified lines are available.
Specifies the pattern for identifying the start of a log message.
Specifies where to start to read data (start_of_file or end_of_file). The default is start_of_file. This setting is only used if there is no state persisted for that log stream.
Specifies the encoding of the log file so that the file can be read correctly. The default is utf_8 . Encodings supported by Python codecs.decode() can be used here.
Specifies the time duration for the batching of log events. The minimum value is 5000ms and default value is 5000ms.
Specifies the max number of log events in a batch, up to 10000. The default value is 1000.
Specifies the maximum size of log events in a batch, in bytes, up to 1048576 bytes. The default value is 32768 bytes. This size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.
An array containing the layer's custom security group IDs.
An array of Package objects that describe the layer's packages.
A VolumeConfigurations object that describes the layer's Amazon EBS volumes.
Describes an Amazon EBS volume configuration.
The volume mount point. For example "/dev/sdh".
The volume RAID level .
The number of disks in the volume.
The volume size.
The volume type. For more information, see Amazon EBS Volume Types .
For PIOPS volumes, the IOPS per disk.
Specifies whether an Amazon EBS volume is encrypted. For more information, see Amazon EBS Encryption .
A LayerCustomRecipes object that specifies the layer's custom recipes.
An array of custom recipe names to be run following a setup event.
An array of custom recipe names to be run following a configure event.
An array of custom recipe names to be run following a deploy event.
An array of custom recipe names to be run following a undeploy event.
An array of custom recipe names to be run following a shutdown event.
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 manually running yum (Amazon Linux) or apt-get (Ubuntu) on the instances.
Note
We strongly recommend using the default value of true , to ensure that your instances have the latest security updates.
A ShutdownEventConfiguration object that specifies the Shutdown event configuration.

[REQUIRED]
The stack name.
[REQUIRED]
The stack's AWS region, such as ap-south-1 . For more information about Amazon regions, see Regions and Endpoints .
Note
In the AWS CLI, this API maps to the --stack-region parameter. If the --stack-region parameter and the AWS CLI common parameter --region are set to the same value, the stack uses a regional endpoint. If the --stack-region parameter is not set, but the AWS 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 us-east-1 API endpoint. Because it is a best practice to choose the regional endpoint that is closest to where you manage AWS, we recommend that you use regional endpoints for new stacks. The AWS CLI common --region parameter always specifies a regional API endpoint; it cannot be used to specify a classic AWS OpsWorks Stacks region.
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 the VPC ID corresponds to a default VPC and you have specified either the DefaultAvailabilityZone or the DefaultSubnetId parameter only, AWS OpsWorks Stacks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks Stacks 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:
For more information about how to use AWS OpsWorks Stacks with a VPC, see Running a Stack in a VPC . For more information about default VPC and EC2-Classic, see Supported Platforms .
One or more user-defined key-value pairs to be added to the stack attributes.
[REQUIRED]
The stack's AWS Identity and Access Management (IAM) role, which allows AWS OpsWorks Stacks 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 .
[REQUIRED]
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 .
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.
The default option is the current Amazon Linux version. For more information about supported operating systems, see AWS OpsWorks Stacks Operating Systems .
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:
To obtain a generated host name, call GetHostNameSuggestion , which returns a host name based on the current theme.
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 format:
"{\"key1\": \"value1\", \"key2\": \"value2\",...}"
For more information about custom JSON, see Use Custom JSON to Modify the Stack Configuration Attributes .
The configuration manager. When you create a stack we recommend that you use the configuration manager to specify the Chef version: 12, 11.10, or 11.4 for Linux stacks, or 12.2 for Windows stacks. The default value for Linux stacks is currently 12.
The name. This parameter must be set to "Chef".
The Chef version. This parameter must be set to 12, 11.10, or 11.4 for Linux stacks, and to 12.2 for Windows stacks. The default value for Linux stacks is 11.4.
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 .
Whether to enable Berkshelf.
The Berkshelf version.
Whether to associate the AWS OpsWorks Stacks built-in security groups with the stack's layers.
AWS 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:
For more information, see Create a New Stack .
Contains the information required to retrieve an app or cookbook from a repository. For more information, see Adding Apps or Cookbooks and Recipes .
The repository type.
The source URL. The following is an example of an Amazon S3 source URL: https://s3.amazonaws.com/opsworks-demo-bucket/opsworks_cookbook_demo.tar.gz .
This parameter depends on the repository type.
When included in a request, the parameter depends on the repository type.
For more information on how to safely handle IAM credentials, see https://docs.aws.amazon.com/general/latest/gr/aws-access-keys-best-practices.html .
In responses, AWS OpsWorks Stacks returns *****FILTERED***** instead of the actual value.
In requests, the repository's SSH key.
In responses, AWS OpsWorks Stacks returns *****FILTERED***** instead of the actual value.
The application's version. AWS OpsWorks Stacks 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.
The default AWS OpsWorks Stacks agent version. You have the following options:
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.
Note
You can also specify an agent version when you create or update an instance, which overrides the stack's default setting.

Specifies log files that you want to push to CloudWatch Logs.
File can point to a specific file or multiple files (by using wild card characters such as /var/log/system.log* ). Only the latest file is pushed to CloudWatch Logs, based on file modification time. We recommend that you use wild card characters to specify a series of files of the same type, such as access_log.2014-06-01-01 , access_log.2014-06-01-02 , and so on by using a pattern like access_log.* . Don't use a wildcard to match multiple file types, such as access_log_80 and access_log_443 . To specify multiple, different file types, add another log stream entry to the configuration file, so that each log file type is stored in a different log group.
Zipped files are not supported.
FileFingerprintLines (string) --
Specifies the range of lines for identifying a file. The valid values are one number, or two dash-delimited numbers, such as '1', '2-5'. The default value is '1', meaning the first line is used to calculate the fingerprint. Fingerprint lines are not sent to CloudWatch Logs unless all specified lines are available.
MultiLineStartPattern (string) --
Specifies the pattern for identifying the start of a log message.
InitialPosition (string) --
Specifies where to start to read data (start_of_file or end_of_file). The default is start_of_file. This setting is only used if there is no state persisted for that log stream.
Encoding (string) --
Specifies the encoding of the log file so that the file can be read correctly. The default is utf_8 . Encodings supported by Python codecs.decode() can be used here.
BufferDuration (integer) --
Specifies the time duration for the batching of log events. The minimum value is 5000ms and default value is 5000ms.

[REQUIRED]
The layer type. A stack cannot have more than one built-in layer of the same type. It can have any number of custom layers. Built-in layers are not available in Chef 12 stacks.
[REQUIRED]
The layer name, which is used by the console.
[REQUIRED]
For custom layers only, use this parameter to specify the layer's short name, which is used internally by AWS OpsWorks Stacks and by Chef recipes. The short name is also used as the name for the directory where your app files are installed. It can have a maximum of 200 characters, which are limited to the alphanumeric characters, '-', '_', and '.'.
The built-in layers' short names are defined by AWS OpsWorks Stacks. For more information, see the Layer Reference .
One or more user-defined key-value pairs to be added to the stack attributes.
To create a cluster layer, set the EcsClusterArn attribute to the cluster's ARN.
Specifies CloudWatch Logs configuration options for the layer. For more information, see CloudWatchLogsLogStream .
Whether CloudWatch Logs is enabled for a layer.
A list of configuration options for CloudWatch Logs.
Describes the Amazon CloudWatch logs configuration for a layer. For detailed information about members of this data type, see the CloudWatch Logs Agent Reference .
Specifies the destination log group. A log group is created automatically if it doesn't already exist. Log group names can be between 1 and 512 characters long. Allowed characters include a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.' (period).
Specifies how the time stamp is extracted from logs. For more information, see the CloudWatch Logs Agent Reference .
Specifies the time zone of log event time stamps.
Specifies log files that you want to push to CloudWatch Logs.
File can point to a specific file or multiple files (by using wild card characters such as /var/log/system.log* ). Only the latest file is pushed to CloudWatch Logs, based on file modification time. We recommend that you use wild card characters to specify a series of files of the same type, such as access_log.2014-06-01-01 , access_log.2014-06-01-02 , and so on by using a pattern like access_log.* . Don't use a wildcard to match multiple file types, such as access_log_80 and access_log_443 . To specify multiple, different file types, add another log stream entry to the configuration file, so that each log file type is stored in a different log group.
Zipped files are not supported.
Specifies the range of lines for identifying a file. The valid values are one number, or two dash-delimited numbers, such as '1', '2-5'. The default value is '1', meaning the first line is used to calculate the fingerprint. Fingerprint lines are not sent to CloudWatch Logs unless all specified lines are available.
Specifies the pattern for identifying the start of a log message.
Specifies where to start to read data (start_of_file or end_of_file). The default is start_of_file. This setting is only used if there is no state persisted for that log stream.
Specifies the encoding of the log file so that the file can be read correctly. The default is utf_8 . Encodings supported by Python codecs.decode() can be used here.
Specifies the time duration for the batching of log events. The minimum value is 5000ms and default value is 5000ms.
Specifies the max number of log events in a batch, up to 10000. The default value is 1000.
Specifies the maximum size of log events in a batch, in bytes, up to 1048576 bytes. The default value is 32768 bytes. This size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.
An array containing the layer custom security group IDs.
An array of Package objects that describes the layer packages.
A VolumeConfigurations object that describes the layer's Amazon EBS volumes.
Describes an Amazon EBS volume configuration.
The volume mount point. For example "/dev/sdh".
The volume RAID level .
The number of disks in the volume.
The volume size.
The volume type. For more information, see Amazon EBS Volume Types .
For PIOPS volumes, the IOPS per disk.
Specifies whether an Amazon EBS volume is encrypted. For more information, see Amazon EBS Encryption .
A LayerCustomRecipes object that specifies the layer custom recipes.
An array of custom recipe names to be run following a setup event.
An array of custom recipe names to be run following a configure event.
An array of custom recipe names to be run following a deploy event.
An array of custom recipe names to be run following a undeploy event.
An array of custom recipe names to be run following a shutdown event.
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.
Note
To ensure that your instances have the latest security updates, we strongly recommend using the default value of true .
A LifeCycleEventConfiguration object that you can use to configure the Shutdown event to specify an execution timeout and enable or disable Elastic Load Balancer connection draining.
A ShutdownEventConfiguration object that specifies the Shutdown event configuration.
The time, in seconds, that AWS OpsWorks Stacks will wait after triggering a Shutdown event before shutting down an instance.
Whether to enable Elastic Load Balancing connection draining. For more information, see Connection Draining
opsworks.Layer
Layer resource
Deletes a specified stack. You must first delete all instances, layers, and apps or deregister registered instances. For more information, see Shut Down a Stack .
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 .
