Options

--layer-id (string)

The layer ID.

--name (string)

The layer name, which is used by the console. Layer names can be a maximum of 32 characters.

--shortname (string)

For custom layers only, use this parameter to specify the layer’s short name, which is used internally by 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 32 characters and must be in the following format: /A[a-z0-9-_.]+Z/.

Built-in layer short names are defined by OpsWorks Stacks. For more information, see the Layer reference in the OpsWorks User Guide.

--attributes (map)

One or more user-defined key/value pairs to be added to the stack attributes.

--cloud-watch-logs-configuration (structure)

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.

(structure)

Describes the 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.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
