aws-lambda-layer-zip-builder:

Build Python compatible AWS Lambda Layers as a zip file with Docker. This uses Amazon Linux 2 with Python 3.7.x. Use this to add a Python compatible lambda layer to your AWS Cloudformation stack. This has been successfully test on:

opencv-python  
numpy
Pillow
spaCy

Docker Start:

Run this in docker for an opencv layer:

docker run --rm -v $(pwd):/package highpoints/aws-lambda-layer-zip-builder opencv-python

This produces a file, opencv-python3-7-x.zip, as the AWS Lambda Layer. The Python version number appends to the filename, so opencv-python3-7-8.zip, for example, is Python version 3.7.8. AWS Lambda Layers only allows one period in the zip filename.

For a numpy layer:

docker run --rm -v $(pwd):/package highpoints/aws-lambda-layer-zip-builder numpy

For a Pillow layer:

docker run --rm -v $(pwd):/package highpoints/aws-lambda-layer-zip-builder pillow

Dockerfile for AWS Lambda Layer:
