如何在Terraform中添加和引用地图作为局部变量的地图？

我想创建地图作为本地变量。我现在正在使用它，

locals {
  region_map = {
     mumbai = {
       is_second_execution = true
       cg_ip_address       = "ip.add.re.ss"
    }
  }
}

我将其称为，

module "mumbai" {
  source                    = "./site-to-site-vpn-setup"
  providers                 = { aws = aws.mumbai }
  is_second_execution       = lookup(local.region_map, local.region_map["mumbai"]["is_second_execution"], false)
  cg_ip_address             = lookup(local.region_map, local.region_map["mumbai"]["cg_ip_address"], "")
}

但是在进行Terrafrom计划时，CG_IP_ADDRESS将设置为null。另外，如果我添加了另一个模块说“ saopaulo”，并且需要传递is_second_execution的默认值和cg_ip_address，而无需在地图中添加saopaulo，我该怎么做？

原文

I want to create a map of map as a local variable. I am using this

locals {
  region_map = {
     mumbai = {
       is_second_execution = true
       cg_ip_address       = "ip.add.re.ss"
    }
  }
}

Now I am referencing it as

module "mumbai" {
  source                    = "./site-to-site-vpn-setup"
  providers                 = { aws = aws.mumbai }
  is_second_execution       = lookup(local.region_map, local.region_map["mumbai"]["is_second_execution"], false)
  cg_ip_address             = lookup(local.region_map, local.region_map["mumbai"]["cg_ip_address"], "")
}

but upon doing terrafrom plan the cg_ip_address is being set to null.
Also If I add another module say "saopaulo" and I need to pass default values of is_second_execution and cg_ip_address for it without adding saopaulo in the map, how do I do that?

查找内置函数[1]具有以下语法：

查找（映射，键，默认）

由于您有一个映射地图，这意味着第一个参数是映射（locion.region_map.mumbai），第二个是您正在寻找的密钥（ cg_ip_address），第三个参数是默认值。因此，在您的情况下，您必须将查找更改为：

module "mumbai" {
  source                    = "./site-to-site-vpn-setup"
  providers                 = { aws = aws.mumbai }
  is_second_execution       = lookup(local.region_map.mumbai, "is_second_execution", false)
  cg_ip_address             = lookup(local.region_map.mumbai, "cg_ip_address", "")
}

The lookup built-in function [1] has the following syntax:

lookup(map, key, default)

Since you have a map of maps, that means that the first argument is the map (local.region_map.mumbai), the second is the key you are looking for (cg_ip_address) and the third argument is the default value. So in your case you have to change the lookup to this:

module "mumbai" {
  source                    = "./site-to-site-vpn-setup"
  providers                 = { aws = aws.mumbai }
  is_second_execution       = lookup(local.region_map.mumbai, "is_second_execution", false)
  cg_ip_address             = lookup(local.region_map.mumbai, "cg_ip_address", "")
}
