Question

我正在尝试从terraform map变量中提取左值和右值，但是无法提取左值。下面是我的代码：-

variables.tf
  variable "notebook" {
    type = "map"
    default = {
    "01" = "a@a.com"
    "02" = "b@a.com"
    "03" = "c@a.com"
    "04" = "d@a.com"
    ......
  }
}

下面是我在main.tf中的模块

 module "instance" {
   instance_ip = ["1.1.1.x", "1.1.2.y", "1.1.1.z","1.1.2.p"]
   dns         = ["x", "y", "z","p"]
   name        = ["a", "b", "c",  "d"]
 }

输出应如下所示：-

 module "instance" {
   instance_ip = ["1.1.1.01", "1.1.2.02", "1.1.1.03","1.1.2.04" and so on]
   dns         = ["01", "02", "03","04" and so on]
   name        = ["a@a.com", "b@a.com", "c@a.com", "d@a.com and so on]
 }

任何建议。我尝试在变量上查找，但只得到a@a.com，而不得到密钥。

您可以为此使用keys和values函数：

# terraform 0.12
module "instance" {
  instance_ip = ["1.1.1.${keys(var.notebook)[0]}", "1.1.1.${keys(var.notebook)[1]}", "1.1.1.${keys(var.notebook)[2]}"]
  dns         = keys(var.notebook)
  name        = values(var.notebook)
}

# terraform 0.11
module "instance" {
  instance_ip = ["1.1.1.${keys(var.notebook)[0]}", "1.1.1.${keys(var.notebook)[1]}", "1.1.1.${keys(var.notebook)[2]}"]
  dns         = ["${keys(var.notebook)}"]
  name        = ["${values(var.notebook)}"]
}

从Terraform映射变量中提取键/值
