Building AWS Lambda Layer by Powershell and Docker on Windows

Since some of the python packages need to be compiled with Cython (or other compiler), we cannot compile those packages in windows directly, therefore, the powershell script in this repo build the packages with Docker (using the image lambci/lambda:build-python3.7 used by AWS Lambda).

How to use?

1. create a folder call python in the directory of the repo
2. modify requirements.txt
3. run .\build_layer.ps1 in poweshell
4. zip python folder to <any name you like>.zip
5. upload to AWS Lambda Layer
