我正在尝试编写一些 Terraform 代码来使用一个资源块创建多个启动配置。它变得棘手的部分是每个启动配置我需要为每个启动配置使用一个独特的模板。我正在使用 Terraform 0.11.10，所以我认为需要使用 count 。下面的代码使用相同的模板创建多个启动配置，我需要能够为每个配置使用不同的模板。任何意见将是有益的。

启动配置

resource "aws_launch_configuration" "launch_configuration" {
  count = "${(var.enable ? 1 : 0) * var.number_of_zones}"

  name      = "${var.cluster_name}-launch_node_${count.index}"
  key_name  = "${var.key_name2}"
  image_id  = "${lookup(var.amis, "${var.aws_region}.${var.licensee_key == "" && var.licensee == "" ? "enterprise" : "byol"}")}"
  user_data = "${element(data.template_file.user_data.*.rendered, count.index)}"

  security_groups = [
    "${aws_security_group.instance_security_group.id}",
  ]

  instance_type        = "${var.instance_type}"
  iam_instance_profile = "${aws_iam_instance_profile.instance_host_profile.name}"

  ebs_block_device {
    device_name = "/dev/sdf"
    no_device   = true
  }

模板文件

data "template_file" "user_data" {
  count    = "${(var.enable ? 1 : 0) * var.number_of_zones}"
  template = "${file("userdata.sh")}"

  vars {
    node                   = "Node${count.index + 1}_#"
    master                 = "${count.index == 0 ? 1 : 0}"
    licensee               = "${var.licensee}"
    licensee_key           = "${var.licensee_key}"
    cluster_name           = "${var.cluster_name}"
    ebs_volume             = "${element(aws_ebs_volume.volume.*.id, count.index)}"
    volume_size            = "${var.volume_size}"
    volume_type            = "${var.volume_type}"
    ansible_git_ssh_key    = "${var.ansible_git_ssh_key}"
    ansible_pull_url       = "${var.ansible_pull_url}"
    ansible_playbook_file  = "${var.ansible_playbook_file}"
    ansible_inventory_file = "${var.ansible_inventory_file}"
    ansible_pull_branch    = "${var.ansible_pull_branch}"
  }
