Hey Marbot team. I'm giving this module a shot. We are using some newer versions for providers and terraform.

stevencerebral@Stevens-MacBook-Pro dev % terraform --version
Terraform v0.14.6
+ provider registry.terraform.io/hashicorp/aws v3.28.0
+ provider registry.terraform.io/hashicorp/random v3.0.1

I did a Terraform init to download your module, then manually patched the module in my .terraform directory to see what would happen. It applied without an issue.

   2   required_version = "~> 0.14"
   3   required_providers {
   4     aws    = ">= 2.48.0"
   5     random = ">= 2.2"
   6   }
   7 }
   8

above: just checking if it would work, not best practice.

Just letting you know - you might consider publishing a new module version with the versioning constraints updated. Thanks for your open source contributions!
