v1.9 Notes

The TF module now supports Zip and Image deployment package types. When you use the Image package type, you must not specify any value for the handler, runtime and layers input variables.

v1.8 Notes

AWS annouced the AWS parameters and secrets lambda extension on Oct 18, 2022. The extension is offered as a lambda layer and can be enabled by setting the use_parameters_and_secrets_layer variable to true.

Usage

module "function" {
  source = "github.com/globeandmail/aws-lambda-function?ref=1.9"

  function_name      = "my-lambda-function"
  tags               = var.tags

  # enable a dead letter queue
  dead_letter_config = {
    target_arn = "SQS or SNS arn"
  }

}
