AWS Lambda Layer Builder

If you've ever needed to build a Lambda layer quickly and easily, this tool is for you.

Prerequisites

Installation

Copy the make-layer file to a location on your path, e.g. cp make-layer /usr/local/bin/.

Download and install with a single command by copying and pasting the following into a terminal:

INSTALL_LOC=/usr/local/bin/make-layer; curl https://raw.githubusercontent.com/aws-samples/aws-lambda-layer-builder/main/make-layer > $INSTALL_LOC; chmod +x $INSTALL_LOC

Usage

This tool can either take a list of packages to include in the layer, or a package manifest file valid for the specified runtime. It assumes the AWS CLI is already properly configured.

Run make-layer without parameters for full usage instructions.

Manifest File

make-layer NAME RUNTIME MANIFEST
  • NAME is a valid Lambda layer name (letters, numbers, hyphens, and underscores)
  • RUNTIME is a valid Lambda runtime identifier (e.g. nodejs14.x, python3.8)
  • MANIFEST is the full path and filename of a valid manifest file. The following types are supported:

If the manifest file is not found the parameters are presumed to be explicit package names.

Explicit List

make-layer NAME RUNTIME PACKAGE_1 [PACKAGE_2] ...
  • PACKAGE_1, PACKAGE_2, etc. are the packages to be installed.

To-Do

  • Add parameter for AWS profile to use (currently uses default, or honors AWS_PROFILE)
  • Add support for additional runtimes
