list-layer-versions

Description

Lists the versions of an Lambda layer . Versions that have been deleted aren’t listed. Specify a runtime identifier to list only versions that indicate that they’re compatible with that runtime. Specify a compatible architecture to include only layer versions that are compatible with that architecture.

See ‘aws help’ for descriptions of global parameters.

list-layer-versions is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: LayerVersions

Synopsis

  list-layer-versions
[--compatible-runtime <value>]
--layer-name <value>
[--max-items <value>]
[--compatible-architecture <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--generate-cli-skeleton <value>]

Options

--compatible-runtime (string)

A runtime identifier. For example, go1.x .

Possible values:

• nodejs

• nodejs4.3

• nodejs6.10

• nodejs8.10

• nodejs10.x

• nodejs12.x

• nodejs14.x

• java8

• java8.al2

• java11

• python2.7

• python3.6

• python3.7

• python3.8

• python3.9

• dotnetcore1.0

• dotnetcore2.0

• dotnetcore2.1

• dotnetcore3.1

• nodejs4.3-edge

• go1.x

• ruby2.5

• ruby2.7

• provided

• provided.al2

--layer-name (string)

The name or Amazon Resource Name (ARN) of the layer.

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--compatible-architecture (string)

The compatible instruction set architecture .

Possible values:

• x86_64

• arm64

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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 list the versions of an AWS Lambda layer

The following list-layers-versions example displays information about the versions for the layer named my-layer.

aws lambda list-layer-versions \
    --layer-name my-layer

Output:

{
    "Layers": [
        {

            "LayerVersionArn": "arn:aws:lambda:us-east-2:123456789012:layer:my-layer:2",
            "Version": 2,
            "Description": "My layer",
            "CreatedDate": "2018-11-15T00:37:46.592+0000",
            "CompatibleRuntimes": [
                "python3.6",
                "python3.7"
            ]

        }
    ]
}
