Question - How do you provide and use python requirements.txt

[ryanash999]

The documentation indicates that a requirements.txt can be used to automatically build with the necessary python modules. Where is requirements.txt placed? How is it referenced? Documentation could be expanded a bit for this portion.

Thanks

Hi.

Just to quickly answer your questions, this test:

terraform-aws-lambda/tests/python-versions/python3/main.tf

Lines 23 to 32 in f9ff6ee

	module "lambda_python3" {
	source = "../../../"
	function_name = "terraform-aws-lambda-test-python3-from-python3"
	description = "Test python3 runtime from python3 environment in terraform-aws-lambda"
	handler = "main.lambda_handler"
	runtime = "python3.7"
	timeout = 5
	source_path = "${path.module}/../lambda"

uses this directory for the source path:

https://github.com/claranet/terraform-aws-lambda/tree/master/tests/python-versions/lambda

And you can see that requirements.txt is just sitting in the top of source directory.

This module copies the source path into a temporary directory, runs pip install requirements.txt if the file exists, zips up the temporary directory, then uses that for the Lambda function package.

Reopening so we don't forget to make this clearer in the readme.
