Hi All,

Anybody can help me out to define a name on any.tf file with concat from multiple variable, for example we would like to use name, environment, domain which is already define on the variables.tf file

Thank you for your help.

Regards,

RH

What you’re looking for is called string interpolation:

bent@DESKTOP-KEO4V17:/tmp/concatvars$ cat variables.tf main.tf
variable "name" {
  default = "server"
}
variable "environment" {
  default = "test"
}
variable "domain" {
  default = "acme.com"
}

output "fqdn" {
  value = "${var.environment}-${var.name}.${var.domain}"
}

bent@DESKTOP-KEO4V17:/tmp/concatvars$ terraform apply

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Outputs:

fqdn = test-server.acme.com
bent@DESKTOP-KEO4V17:/tmp/concatvars$
