遍历 terraform 模块中的对象映射

Question

我需要构建2-3个vnet，在单个vnet下，我们需要构建2个子网。

下面是我的代码：

**variables.tf**

variable "vnet_config" {

  type = map(object({
    vnet_name      = string
    address_space  = list(string)
  }))
}

    **vnet.auto.tfvars**
    
    vnet_config = {
    
      vnet1 = {
        vnetname       = "bupa1"
        address_space  = ["10.0.0.0/16"]
      },
    
      vnet2 = {
        vnetname      = "bupa2"
        address_space  = ["192.168.0.0/24"]
      }

}

****main.tf****

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=2.98.0"
    }
  }
}

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "rg1" {
  name     = "rg1"
  location = "West Europe"
}

module vnet {
  source              = "./vnet"
  resource_group_name = azurerm_resource_group.rg1.name
  for_each            = var.vnet_config
  vnet_name           = each.value.vnetname
  address_space       = each.value.address_space
  
}

module "subnet" {
  source                  = "./subnet"
  resource_group_name     = azurerm_resource_group.example.name
  vnet_name               = module.vnet.vnet_name
  subnet_name             = "test20"
  subnet_address_prefixes = "10.0.1.0/24"
}

output.tf

output "vnet_id" {
  description = "The id of the newly created vNet"
  value       = azurerm_virtual_network.vnet.id
}

output "vnet_name" {
  description = "The Name of the newly created vNet"
  value       = azurerm_virtual_network.vnet.name
}

output "vnet_location" {
  description = "The location of the newly created vNet"
  value       = azurerm_virtual_network.vnet.location
}

output "vnet_address_space" {
  description = "The address space of the newly created vNet"
  value       = azurerm_virtual_network.vnet.address_space
}

vnet_name = module.vnet.vnet_name

以上语句将不起作用，因为在 vnet 模块中创建了两个 vnet。

我已经创建了 vnet 和子网的模块，我正在调用它们来创建 vnet 和子网。

请你帮我解决这个问题。

谢谢

您可以为每个子网创建一个唯一的引用。对于每一个，您都可以创建多个副本，每个 vnet 一个。

module "subnet1" {
 for_each = module.vnet

 ...

 vnet_name = each.value.vnet_name                  
 subnet_name             = "test10"
}

module "subnet2" {
 for_each = module.vnet

 ...

 vnet_name = each.value.vnet_name                  
 subnet_name             = "test20"
}

既然你使用了for_each，如果你想引用单个vnet的使用， module."NAME"["KEY"].ATTRIBUTE 例如 module.vnet["vnet1"].vnet_name
