Oder eine Variable definieren um diese öfter zu verwenden:

locals {
web\_user\_data = templatefile("${path.module}/init.ps1", {
environment = var.env
hostnames = {"dev":"devhost","test":"testhost","prod":"prodhost"}
})
}
resource "aws\_instance" "web" {
ami = "ami-xxxxxxxxxxxxxxxxx"
instance\_type = "t2.micro"
user\_data = local.web\_user\_data
tags = {
Name = "HelloWorld"
}
}
