使用 for_each 循环创建的多个子网的值输出

Output of values from multiple subnets created using a for_each loop

我使用如下所示的 for_each 循环创建了一些子网

main.tf 在子模块中

resource "azurerm_subnet" "obc_subnet" {
name                  = var.subnet_name
address_prefixes      = var.address_prefixes
resource_group_name   = var.resource_group_name
virtual_network_name  = var.vnet_name
}

main.tf 根模块

module "deploy_subnet" {
  source              = "./modules/azure_subnet"
  for_each              = var.prefix
  subnet_name           = each.value["name"]
  address_prefixes      = [each.value["cidr"]]
  subscription_id       = var.subscription_id
  resource_group_name   = var.resource_group_name
  region                = var.region
  vnet_name             = var.vnet_name
}

variables.tf 根模块

variable "prefix" {
  type  = map(object({
    name = string
    cidr = string
  }))
  default = {
    sub-1 = {
      name = "aks-sn"
      cidr = "10.0.1.0/24"
    }
    sub-2 = {
      name = "postgres-sn"
      cidr = "10.0.2.0/24"
    }
    sub-3 = {
      name = "keyvault-sn"
      cidr = "10.0.3.0/24"
    }
  }
}

一切正常,除非我尝试输出与 3 个子网关联的值(例如 id)

我正在尝试在输出中使用 for k 语法,但我不太了解它的外观。

我的子模块output.tf中有以下内容

output "subnet_ids" {
  value = tomap({
    for k, subnets in azurerm_subnet.obc_subnet : k => subnets.id
      })
}

我不确定如何处理根模块中的 output.tf,所以我将其保留原样

output "subnet_id" {
  value = module.deploy_subnet.subnet_id
}

我收到一条错误消息,指出该值没有属性

Error: 

Unsupported attribute
  on modules/azure_subnet/output.tf line 3, in output "subnets_id":
   3:     for k, subnets in azurerm_subnet.obc_subnet : k => subnets.is

This value does not have any attributes.

接近,但相反。

子模块中的azurerm_subnet资源不是一个集合,所以那里的输出应该是:

output "subnet_id" {
  value = azurerm_subnet.obc_subnet.id
}

但是在根模块中您有子模块的集合。例如:

output "subnet_ids" {
  value = {
    for k, subnet in module.deploy_subnet : k => subnet.subnet_id
  }
}
