PipLayer
# Note: this snippet needs to be placed in the Resources section of a CloudFormation template
# By default this will create a layer for the python version that the custom resource lambda is running in, so if you want
# a layer for python 3.6, just replace the runtime of the PipLayerLambda.
# This gist accomanies an article on my blog: https://blog.claude.nl/tech/howto/2021/02/10/aws-lambda-python-with-packages-through-pip-in-cloudformation.html
