Terraform: Build resource in one environment

Does anyone know if something like this can be done in terraform 11:

You can use count for such scenario:

resource "aws_s3_bucket" "feedback_service_bucket" {
  count = "${var.account_name == "prod" ? 1 : 0}"
  bucket = "ces-${var.environment}-QA-compendex" 
  acl = "private"
}

You can refer to this: https://www.terraform.io/docs/configuration-0-11/interpolation.html#conditionals

I will upgrade soon to terraform 13, but as this is required in this sprint I don’t have time.

For info, Terraform 0.13 won’t give you much advantages for this specific use case. You would still use count. What changes in 0.13 regarding conditional resources is that you have an alternative using for_each – introduced with v0.12 – and in which you can achieve the same behavior.
