Creates an Lambda layer from a ZIP archive¶

Description¶

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

Add layers to your function with create_function or update_function_configuration.

Usage¶

lambda_publish_layer_version(LayerName, Description, Content,
  CompatibleArchitectures, CompatibleRuntimes, LicenseInfo)

Arguments¶

LayerName

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

Description

The description of the version.

Content

[required] The function layer archive.

CompatibleArchitectures

A list of compatible instruction set architectures.

CompatibleRuntimes

A list of compatible function runtimes. Used for filtering with list_layers and list_layer_versions.

The following list includes deprecated runtimes. For more information, see Runtime deprecation policy.

LicenseInfo

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.
