[ aws . greengrass ]



Retrieves information about a Lambda function definition version, including which Lambda functions are included in the version and their configurations.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--function-definition-id <value>
--function-definition-version-id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--function-definition-id (string) The ID of the Lambda function definition.

--function-definition-version-id (string) The ID of the function definition version.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


Arn -> (string)

The ARN of the function definition version.

CreationTimestamp -> (string)

The time, in milliseconds since the epoch, when the function definition version was created.

Definition -> (structure)

Information on the definition.

Functions -> (list)

A list of Lambda functions in this function definition version.


Information about a Lambda function.

FunctionArn -> (string)

The ARN of the Lambda function.

FunctionConfiguration -> (structure)

The configuration of the Lambda function.

EncodingType -> (string)

The expected encoding type of the input payload for the function. The default is ''json''.

Environment -> (structure)

The environment configuration of the function.

AccessSysfs -> (boolean)

If true, the Lambda function is allowed to access the host's /sys folder. Use this when the Lambda function needs to read device information from /sys.

ResourceAccessPolicies -> (list)

A list of the resources, with their permissions, to which the Lambda function will be granted access. A Lambda function can have at most 10 resources.


A policy used by the function to access a resource.

Permission -> (string)

The permissions that the Lambda function has to the resource. Can be one of ''rw'' (read/write) or ''ro'' (read-only).

ResourceId -> (string)

The ID of the resource. (This ID is assigned to the resource when you create the resource definiton.)

Variables -> (map)

Environment variables for the Lambda function's configuration.

key -> (string)

value -> (string)

ExecArgs -> (string)

The execution arguments.

Executable -> (string)

The name of the function executable.

MemorySize -> (integer)

The memory size, in KB, which the function requires.

Pinned -> (boolean)

True if the function is pinned. Pinned means the function is long-lived and starts when the core starts.

Timeout -> (integer)

The allowed function execution time, after which Lambda should terminate the function. This timeout still applies to pinned lambdas for each request.

Id -> (string)

The ID of the Lambda function.

Id -> (string)

The ID of the function definition version.

Version -> (string)

The version of the function definition version.
