variable "filenames" {
  type = set(string)
  default = [
    "/tmp/demo1.txt",
    "/tmp/demo2.txt",
    "/tmp/demo3.txt"
  ]
}

resource "local_file" "demo" {
  filename = each.value
  for_each = var.filenames
}

或者：

variable "filenames" {

  default = [
    "/tmp/demo1.txt",
    "/tmp/demo2.txt",
    "/tmp/demo3.txt"
  ]
}

resource "local_file" "demo" {
  filename = each.value
  for_each = toset(var.filenames)
}
