azure 蔚蓝色nics上的地形foreach(Map)

I'm trying to convert those variables in main.tf to terraform.tfvars and variables.tf ( declarer the variables in terraform.tfvars and variables.tf ).
我希望在创建新VM时使用几个网络接口名称和虚拟机名称并在它们上循环来创建Map（Map是必需，因为我对每个都使用）。

- 主文件. tf**

here i create the variables in the main.tf but as i wrote i want to declarer them in the variables.tf file

variable "nics" {
  type = map(any)
  default = {

    nic3 = {
      name = "ubuntutest3"
    }

    nic4 = {
      name = "ubuntutest4"
    }
  }
}

variable "vms" {
  description = "Virtual Machines"
  type        = map(any)
  default = {
    vm3 = {
      name = "ubuntutest3"
      size = "Standard_DS1_v2"
      nic  = "nic3"
    }
    vm4 = {
      name = "ubuntutest4"
      size = "Standard_DS1_v2"
      nic  = "nic4"
    }
  }
}

// VNICs
resource "azurerm_network_interface" "nics" {
  for_each            = var.nics
  name                = each.value.name
  location            = azurerm_resource_group.rg.location
  resource_group_name = azurerm_resource_group.rg.name

  ip_configuration {
    name                          = "${each.value.name}-conf"
    subnet_id                     = azurerm_subnet.subnet.id
    private_ip_address_allocation = "Dynamic"
  }
}

当我创建虚拟机时，

network_interface_ids            = [azurerm_network_interface.nics[each.value.nic].id, ]

when i tried to declarer those variables in variable.tf file and terraform.tfvars i got error massage

│ Error: Invalid index
│
│   on main.tf line 259, in resource "azurerm_virtual_machine" "vms":
│  259:   network_interface_ids            = [azurerm_network_interface.nics[each.value.nic].id, ]
│     ├────────────────
│     │ azurerm_network_interface.nics is object with 2 attributes
│     │ each.value.nic is "network_interface_2"
│
│ The given key does not identify an element in this collection value.

how should i declarer on vm names and nic names in variables.tf and create the names i want to use in terraform.tfvars and use them I'm main.tf ?

- 已编辑**

我试过这样

- 地形变化**

nics = {
  nic_names = ["nic2,nic3"]
}

- 变量. tf**

variable "nics" {
  type = object({
    nic_names = list(string)
  })
}

得到错误

│ Error: Unsupported attribute
│
│   on main.tf line 272, in resource "azurerm_network_interface" "nics":
│  272:   name                = each.value.nic_names
│     ├────────────────
│     │ each.value is list of string with 1 element
│
│ This value does not have any attributes.

您的错误与使用的tfvar而不是变量无关。错误明确指出，当您创建VM时，each.value.nic在此特定迭代中是network_interface_2，而在nicsMap中您只有键nic3和nic4。
至于第二部分，您可能希望键入：

nic_names = ["nic2","nic3"]

而不是：

nic_names = ["nic2,nic3"]

第二种是只有一个字符串的列表，第一种是两个元素的列表。

- 编辑**

要直接演示@ITBYD如何将其文件设置为工作解决方案：
terraform.tfvars:

nics = {
  nic_names = ["nic2","nic3"]
}

main.tfvars:

variable "nics" {
  type = object({
    nic_names = list(string)
  })
}

# [...]

resource "azurerm_network_interface" "nics" {
  for_each            = toset(var.nics["nic_names"])
  name                = each.value
  location            = azurerm_resource_group.rg.location
  resource_group_name = azurerm_resource_group.rg.name

  ip_configuration {
    name                          = "${each.value}-conf"
    subnet_id                     = azurerm_subnet.subnet.id
    private_ip_address_allocation = "Dynamic"
  }
}

但我不会使用列表，只使用Map，就像我之前写的那样。
