I want to do something like this. What is the correct syntax?
variable "location" {
description = "Location of the project in Azure"
default = "cc"
}
variable "env" {
description = "infrastructure environment"
default = "z"
}
variable "prefix" {
description = "Prefix for objects"
default = "${var.env}-${var.location}"
}
You can’t compose a variable from another variable, but there is another type of variable called local that allows this.
e.g.
# define prefix
locals {
prefix = "${var.env}-${var.location}"
}
# use prefix
resource "..." "..." {
name = local.prefix
}
But can the locally defined parts be used outside of the scope of that file?
Yes anywhere within the scope of Terraform module / directory.
