Add default_target_group_arn_suffix Output about terraform-aws-alb HOT 2 CLOSED

I have the same issue myself. I came here to suggest the same thing.

How I dealt with it was to use the aws_arn data source

data "aws_arn" "alb_target_group" {
  arn = module.alb.default_target_group_arn
}

module "alb_alarms" {
  source  = "cloudposse/alb-target-group-cloudwatch-sns-alarms/aws"
  version = "0.15.0"

  alb_arn_suffix          = module.alb.alb_arn_suffix
  target_group_arn_suffix = trimeprefix(data.aws_arn.alb_target_group.resource, "/targetgroup")
}

Regardless of the means, an output from the module would save us the need to have to use an extra data source when combining with alb-target-group-cloudwatch-sns-alarms.

Part of the reason I love using the cloudposse modules is the interoperability of their modules. Everything can be mixed-and-matched and will still work. I have wrapped multiple of cloudposse's modules to form modules myself bringing upto 3-4 levels of module nesting.

Let me see if I can put up a pull request for this soon.
