You have to specify lambda layers as ARNs in terraform using layers parameter:
layers - (Optional) List of Lambda Layer Version ARNs (maximum of 5) to attach to your Lambda Function.
Using the following syntax in terraform:
layers = ["layer-arn"]
For example, the ARN for AWSLambda-Python27-SciPy1x in us-east-1 region is:
arn:aws:lambda:us-east-1:668099181075:layer:AWSLambda-Python27-SciPy1x:24
If you not sure what is your ARN, you can create a dummy a Python 2.7 lambda function, add AWS layer AWSLambda-Python27-SciPy1x layer, and the console will give you its ARN.

How do you handle Lambdas when using terraform?
I have a reusable module for lambdas that has a dummy zip file with one dummy text file in it. I provision the lambda, permissions, cron, env, whatever it needs. Then I use GitHub Actions to actually publish the real zip file. My IAC and app code live in different repos. More on reddit.com

May 29, 2024I worked on an AWS + Terraform project and would like to upload it to Github, should I avoid uploading my Lambda layers? What's best practice for showcasing my work with Terraform on Github?
Terraform can package your lambda folder into a zip and then publish it as a function. Same with the layer: can be packaged same way and then published as lambda_layer_version . You definitely should not be committing your zip files to the repo, as those are generated artifacts. More on reddit.com

It should look something like this, using base64sha256 data "archive_file" "lambda_zip" { type = "zip" source_dir = "../dir/lambda.py" output_path = "../dir/lambda_package.zip" } resource "aws_lambda_function" "func" { description = "some description" function_name = "lambda" filename = data.archive_file.lambda_zip.output_path runtime = "python3.7" handler = "lambda_handler" source_code_hash = data.archive_file.lambda_zip.output_base64sha256 role = aws_iam_role.function_role.arn timeout = var.timeout publish = true } Excuse the formatting, I’m on mobile.

Why not let terraform do the zipping for you? No need to S3 it to a bucket: data "archive_file" "my_function_lambda_payload" { type = "zip" source_dir = var.my_function_lambda_src_dir excludes = [ "venv", "_pycache_" ] output_path = "${var.my_function_lambda_payload_dir}/payload.zip" } resource "aws_lambda_function" "my_function" { filename = data.archive_file.my_function_lambda_payload.output_path source_code_hash = data.archive_file.my_function_lambda_payload.output_base64sha256 ... }

How to deploy an AWS Lambda function with a layer using Terraform
June 10, 2023 - To create a layer, we just need to reference the module location (could be an external registry or local machine), in my the lambda layer location is one back folder at my root directory: module "lambda_noiselesstech" { source = "../terraform-aws-lambda" // A public registry path is allowed too code_location = "./lambdas/example" filename = "example.zip" lambda_function_name = "NoiselesstechExample" lambda_runtime = "nodejs14.x" layer_arn = module.layer.arn environment_variables = { secret = "super secret value" } }

How to lightweight your Python AWS Lambda functions with AWS Lambda Layer, Docker, and Terraform. | by Tanguy Combe | WeScale | Medium
April 11, 2022 - Fortunately, AWS developed a new feature named AWS Lambda Layer to let you build common packages usable by the runtime. We will dive into this use case: how can I package with ease a big Python library and use it through AWS console within one or multiple Lambda functions? Suppose that you have some data engineering stuff to do, you may need to use Pandas to workaround your application. ... Terraform ~> 0.11.12 to use filebase64hash256 for Terraform to detect code changes, it can also work with base64sha256(file()) for Terraform earlier versions.
