AWS region as variable

[stavxyz]

@vadimAnte thanks!

What happens if the variable is unset? I assume it will use AWS_DEFAULT_REGION, and if that is also unset then the tf run will fail?

You are welcome. If you added default value and user started few times it could be hard to change after. If user uses CloudFront better to use default = "us-east-1". If user does not use CloudFront closest location is preferable.

May be better add an example for varibles.tf

variable "backend_region" {
  type = "string"
  description = "AWS region"
  default = "us-east-1"
}

main.tf example:

module "backend" {
  /*
   * Since this example lives in the module repository,
   * we use a relative path '../', but typically we would use
   * the github url, like so:
   *
   * source = "github.com/samstav/terraform-aws-backend"
  */

  # source         = "../../"
  # source = "./modules/backend_aws_s3"
  source = "git::git@github.com:samstav/terraform-aws-backend.git//backend_aws_s3?ref=v1.0"
  backend_bucket = "${var.backend_bucket}"
  backend_region = "${var.backend_region}"
}

The module returns error if variable "backend_region" was hod defined.
