terraform-aws-ebs-optimized

A terraform module to return true or false based on if an instance type supports the EBS optmized flag. If you want to use various instance types and EBS optimization, this module does the heavy lifting of determining if that's possible. Without the module, EC2 instance creation would fail on unsupported types and -- even worse -- launch configurations will create normally but fail silently when instances attempt to launch. This module means you don't need to think about that problem.

Usage example

A full example leveraging other community modules is contained in the examples/ebs_optimized_test_fixture. Here's the gist of using it via the Terraform registry:

variable "web_type" {
  description = "Size/type of the host."
  default     = "m1.large"
}

module "ebs_optimized" {
  source        = "terraform-aws-modules/ebs-optimized/aws"
  instance_type = "${var.web_type}"
}

resource "aws_instance" "web" {
  ami           = "${data.aws_ami.ubuntu.id}"
  instance_type = "${var.web_type}"
  ebs_optimized = "${module.ebs_optimized.answer}"
}

Inputs

Name	Description	Type	Default	Required
instance_type	Instance type to evaluate if EBS optimized is an option.	string	-	yes

Outputs

Name	Description
answer	Returns 1 (true) or 0 (false) depending on if the instance type is able to be EBS optimized.
