我正在尝试为常见任务创建一个公共user_data文件,例如文件夹创建和某些软件包安装,以及一个单独的user_data文件,用于特定于应用程序的配置

我正在尝试以下 -

user_data = "${data.template_file.userdata_common.rendered}", "${data.template_file.userdata_master.rendered}"

有了这些配置 -

通用用户数据模板

data "template_file" "userdata_common" {
  template = "${file("${path.module}/userdata_common.sh")}"

  vars {
    "ALBTarget"          = "${var.ALBTarget}"
    "s3bucket"           = "${var.s3bucket}"
    "centrifydomain"     = "${lookup(var.centrifydomain, format("%s-%s", lower(var.env),var.region))}"
    "centrifyadgroup"    = "${lookup(var.centrifyadgroup, format("%s-%s", lower(var.env),var.region))}"
  }
}

应用程序特定配置

data "template_file" "userdata_master" {
  template = "${file("${path.module}/userdata_master.sh")}"

  vars {
    "ALBTarget"          = "${var.ALBTarget}"
    "s3bucket"           = "${var.s3bucket}"
    "centrifydomain"     = "${lookup(var.centrifydomain, format("%s-%s", lower(var.env),var.region))}"
    "centrifyadgroup"    = "${lookup(var.centrifyadgroup, format("%s-%s", lower(var.env),var.region))}"
  }
}

我做计划时得到以下错误 -

Failed to load root config module: Error parsing /terraform/main.tf: key ${data.template_file.userdata_common.rendered}"' expected start …

由于我是redis的新手,我需要一些关于如何在REDIS中存储以下复杂json的指导,以便我们可以从REDIS访问JSON的元素 -
