我从我的代码中得到了这个片段：
这将创建number_of_resources中定义的3个NIC

resource "azurerm_network_interface" "nic" {
  count = var.number_of_resources
  name  = "nic-${element(var.resourcese_name, count.index)}"
    
  location            = var.location
  resource_group_name = var.rg
    
  ip_configuration {
    subnet_id = azurerm_virtual_network.main_net.*.subnet[0].id
  }
}

字符串
VM块，这将创建3个VM：

resource "azurerm_windows_virtual_machine" "VMs"{
  count = var.number_of_resources
    
  name = "VM-${element(var.resources_name, count.index)}"
  resource_group_name = var.rg
    
  location = var.location
    
  network_interface_ids = [?]
}

每个VM都需要将其自己的网络接口卡（NIC）连接到同一子网。我已经定义了创建VM及其各自NIC所需的变量和资源。
但是，当我尝试使用ID将每个VM与其相应的NIC关联时，我遇到了一个问题。
尝试将nsg与NIC关联时出现相同问题：

resource "azurerm_network_interface_security_group_association" "example" {
   count = var.number_of_resources
    
   network_interface_id      = azurerm_network_interface.nic[count.index + 1].id
   network_security_group_id = azurerm_network_security_group.main-nsg[count.index + 1].id
}

网址：Variable.tf

variable "rg" {
  description = "The default resource group for this proj"
  type = string   
  default = "rg_ADLab"
}
    
variable "location"{
  description = "the default location for this proj"
  type = string
  
  default = "East US"
}

variable "resources_name" {
  type = list(string)
  default = [ "DC","Client1", "Client2" ]
}

variable "number_of_resources"{
  type = number
 
  default = 3
}
