地形变量中的地图内的地图 [英] Map within a map in terraform variables

问题描述

有谁知道是否有可能用代码片段来表示我是否可以在 terraform 变量的地图变量中创建地图变量?

Does anyone know if it's possible with possibly code snipits representing whether I can create a map variable within a map variable in terraform variables?

variable "var" {
  type = map
  default = {
    firstchoice = {
      firstAChoice ="foo"
      firstBChoice = "bar"
    }
    secondchoice = {
      secondAChoice = "foobar"
      secondBChoice = "barfoo"
    }
  }
}

如果有人对这是否可行或任何详细说明的文档有任何见解，那就太好了.

If anyone has any insight to whether this is possible or any documentation that elaborates that would be great.

推荐答案

是的，可以将地图变量作为地图变量键的值.您的变量只需要正确的缩进.此外，我正在尝试访问该变量.

Yes, it's possible to have map variable as value of map variable key. Your variable just needed right indentation. Also I am putting ways to access that variable.

variable "var" {
  default = {
    firstchoice = {
      firstAChoice = "foo"
      firstBChoice = "bar"
    }

    secondchoice = {
      secondAChoice = "foobar"
      secondBChoice = "barfoo"
    }
  }
}

要访问地图键的整个地图值firstchoice，您可以尝试以下

To access entire map value of a map key firstchoice, you can try following

value = "${var.var["firstchoice"]}"

output:
{
  firstAChoice = foo
  firstBChoice = bar
}

要访问该映射键的特定键(例如firstAchoice)，您可以尝试

To access specific key of that map key (example firstAChoice), you can try

value = "${lookup(var.var["firstchoice"],"firstAChoice")}"

output: foo
