How to add python libraries to lambda using the CDK?

Question

I want to use a library in my lambda function that was created by the CDK.

I did the following, without success:

1) add the library to my requirements.txt file

Pillow

2) import the library in my lambda function

from PIL import Image

3) install it and deploy

source .env/bin/activate
    pip install -r requirements.txt
    cdk deploy`

Many thanks for any hints!

You should have a look at the **aws-lambda-python** module: https://docs.aws.amazon.com/cdk/api/latest/docs/aws-lambda-python-readme.html

It's still experimental and needs docker, but it will take care of your requirements.txt.

The same exists for nodejs just in case (https://docs.aws.amazon.com/cdk/api/latest/docs/aws-lambda-nodejs-readme.html).
