publish-layer-version¶

Description¶

Creates an Lambda layer from a ZIP archive. Each time you call PublishLayerVersion with the same layer name, a new version is created.

Add layers to your function with CreateFunction or UpdateFunctionConfiguration .

--license-info (string)

The layer’s software license. It can be any of the following:

An SPDX license identifier . For example, MIT .

The URL of a license hosted on the internet. For example, https://opensource.org/licenses/MIT .

The full text of the license.

--compatible-architectures (list)

A list of compatible instruction set architectures .

(string)

Syntax:

"string" "string" ...

Where valid values are:
  x86_64
  arm64

--zip-file (blob)

The path to the zip file of the content you are uploading. Specify –zip-file or –content, but not both. Example: fileb://content.zip

--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.

See ‘aws help’ for descriptions of global 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 .

To create a Lambda layer version

The following publish-layer-version example creates a new Python library layer version. The command retrieves the layer content a file named layer.zip in the specified S3 bucket.

aws lambda publish-layer-version \
    --layer-name my-layer \
    --description "My Python layer" \
    --license-info "MIT" \
    --content S3Bucket=lambda-layers-us-west-2-123456789012,S3Key=layer.zip \
    --compatible-runtimes python3.6 python3.7

Output:

{
    "Content": {
        "Location": "https://awslambda-us-west-2-layers.s3.us-west-2.amazonaws.com/snapshots/123456789012/my-layer-4aaa2fbb-ff77-4b0a-ad92-5b78a716a96a?versionId=27iWyA73cCAYqyH...",
        "CodeSha256": "tv9jJO+rPbXUUXuRKi7CwHzKtLDkDRJLB3cC3Z/ouXo=",
        "CodeSize": 169
    },
    "LayerArn": "arn:aws:lambda:us-west-2:123456789012:layer:my-layer",
    "LayerVersionArn": "arn:aws:lambda:us-west-2:123456789012:layer:my-layer:1",
    "Description": "My Python layer",
    "CreatedDate": "2018-11-14T23:03:52.894+0000",
    "Version": 1,
    "LicenseInfo": "MIT",
    "CompatibleRuntimes": [
        "python3.6",
        "python3.7"
    ]
}
