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 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 .

string
[REQUIRED]
The layer stack ID.
string
[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.
string
[REQUIRED]
The layer name, which is used by the console.
string
[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 .
dict
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.
(string) --
(string) --
dict
Specifies CloudWatch Logs configuration options for the layer. For more information, see CloudWatchLogsLogStream .
Enabled (boolean) --
Whether CloudWatch Logs is enabled for a layer.
LogStreams (list) --
A list of configuration options for CloudWatch Logs.
(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) --
Specifies how the time stamp is extracted from logs. For more information, see the CloudWatch Logs Agent Reference .
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.
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.
BatchCount (integer) --
Specifies the max number of log events in a batch, up to 10000. The default value is 1000.
BatchSize (integer) --
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.
string
The ARN of an IAM profile to be used for the layer's EC2 instances. For more information about IAM ARNs, see Using Identifiers .

string
[REQUIRED]
The layer ID.
string
The layer name, which is used by the console.
string
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
dict
One or more user-defined key/value pairs to be added to the stack attributes.
(string) --
(string) --
dict
Specifies CloudWatch Logs configuration options for the layer. For more information, see CloudWatchLogsLogStream .
Enabled (boolean) --
Whether CloudWatch Logs is enabled for a layer.
LogStreams (list) --
A list of configuration options for CloudWatch Logs.
(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) --
Specifies how the time stamp is extracted from logs. For more information, see the CloudWatch Logs Agent Reference .
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.
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.
BatchCount (integer) --
Specifies the max number of log events in a batch, up to 10000. The default value is 1000.
BatchSize (integer) --
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.
string
The ARN of an IAM profile to be used for all of the layer's EC2 instances. For more information about IAM ARNs, see Using Identifiers .
string
A JSON-formatted string containing custom stack configuration and deployment attributes to be installed on the layer's instances. For more information, see Using Custom JSON .
list
An array containing the layer's custom security group IDs.
(string) --
list
An array of Package objects that describe the layer's packages.

The volume RAID level .
NumberOfDisks (integer) -- [REQUIRED]
The number of disks in the volume.
Size (integer) -- [REQUIRED]
The volume size.
VolumeType (string) --
The volume type. For more information, see Amazon EBS Volume Types .

io1 - Provisioned IOPS (SSD)
gp2 - General Purpose (SSD)
st1 - Throughput Optimized hard disk drive (HDD)
sc1 - Cold HDD
Iops (integer) --
For PIOPS volumes, the IOPS per disk.
Encrypted (boolean) --
Specifies whether an Amazon EBS volume is encrypted. For more information, see Amazon EBS Encryption .
boolean
Whether to disable auto healing for the layer.
boolean
Whether to automatically assign an Elastic IP address to the layer's instances. For more information, see How to Edit a Layer .
boolean
For stacks that are running in a VPC, whether to automatically assign a public IP address to the layer's instances. For more information, see How to Edit a Layer .
dict
A LayerCustomRecipes object that specifies the layer's custom recipes.
Setup (list) --
An array of custom recipe names to be run following a setup event.
(string) --

An array of custom recipe names to be run following a shutdown event.
(string) --
boolean
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.
boolean
Whether to use Amazon EBS-optimized instances.
