[ aws . lambda ]

get-function

Description

Returns the configuration information of the Lambda function and a presigned URL link to the .zip file you uploaded with CreateFunction so you can download the .zip file. Note that the URL is valid for up to 10 minutes. The configuration information is the same information you provided as parameters when uploading the function.

Use the Qualifier parameter to retrieve a published version of the function. Otherwise, returns the unpublished version ($LATEST ). For more information, see AWS Lambda Function Versioning and Aliases .

This operation requires permission for the lambda:GetFunction action.

See 'aws help' for descriptions of global parameters.

Synopsis

  get-function
--function-name <value>
[--qualifier <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--function-name (string)

The name of the lambda function.

Name formats
  • Function name - MyFunction .
  • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction .
  • Partial ARN - 123456789012:function:MyFunction .

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

--qualifier (string)

Specify a version or alias to get details about a published version of the function.

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.
