Description

Returns information about a version of an Lambda layer , with a link to download the layer archive that’s valid for 10 minutes.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-layer-version-by-arn
--arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--arn (string)

The ARN of the layer version.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To retrieve information about a Lambda layer version

The following get-layer-version-by-arn example displays information about the layer version with the specified Amazon Resource Name (ARN).

aws lambda get-layer-version-by-arn \
    --arn "arn:aws:lambda:us-west-2:123456789012:layer:AWSLambda-Python37-SciPy1x:2"
