terraform-aws-pythonll

Terraform module that builds AWS Lambda layers from a list of Python dependencies. Packages are installed inside Docker for platform-consistent builds, so layers work on Lambda regardless of the machine running Terraform.

module "python_layer" {
  source            = "MarioMoura/pythonll/aws"
  layer_name        = "my_python_layer"
  layer_name_prefix = var.environment
  requirements = [
    "requests==2.32.3",
    "numpy==2.1.0",
  ]
}

Name	Description	Type	Default

layer_name	Name of the layer	string	required
layer_name_prefix	Prefix for the layer name, generally the environment	string	null
python_version	Python version to build against	string	"3.13"
