当网卡有ipv6和ipv6地址时，ipv4地址在ipv6中

Question

我正在使用terraform创建一个资源组。资源组具有具有ipv4和ipv6地址的NIC的虚拟机。我正在尝试创建一个具有ipv4、ipv6 ip地址的后端地址池的负载均衡器，我可以用ipv4创建后端池，但不能用ipv6创建后端池。我需要知道如何访问NIC的ipv6地址，以便在ip_address部件中调用它。

ip_address = azurerm_network_interface.vm-outside[count.index].private_ip_address中的某些内容需要更改，但不确定要更改什么。

如果我静态地添加一个ipv6地址，比如ip_address = "fd00:ab8:deca:4::4“，我可以创建它，我需要一种动态方式，因为我想要创建多个vm和ipv6地址。

需要知道如何动态地将ip_address指向网卡的辅助ipv6地址。

variable "instances" {
  default     = 2
  description = "Number of instances"
}
resource "azurerm_network_interface" "vm-outside" {
  depends_on          = [azurerm_subnet.subnets]
  name                = "${var.prefix}-xxx%{if var.instances > 1}-${count.index}%{endif}"
  count               = var.instances
  location            = var.location
  resource_group_name = local.rg_name

  ip_configuration {
    name                          = "xxx-ipv4%{if var.instances > 1}-${count.index}%{endif}"
    subnet_id                     = azurerm_subnet.subnets["xxx"].id
    private_ip_address_allocation = "Dynamic"

    primary                       = true
  }
   ip_configuration {
    name                          = "xxx-ipv6%{if var.instances > 1}-${count.index}%{endif}"
    subnet_id                     = azurerm_subnet.subnets["xxx"].id
    private_ip_address_allocation = "Dynamic"
    private_ip_address_version    = "IPv6"
  }

 
}
resource "azurerm_lb_backend_address_pool_address" "backend-address-ipv4" {
  count                   = var.instances > 1 ? var.instances : 0
  name                    = "backend-address-%{if var.instances > 1}-${count.index}%{endif}"
  backend_address_pool_id = azurerm_lb_backend_address_pool.backend-address-Pool[0].id
  virtual_network_id      = var.vn ? azurerm_virtual_network.vm[0].id : data.azurerm_virtual_network.vm[0].id
  ip_address              = azurerm_network_interface.vm-outside[count.index].private_ip_address
}

resource "azurerm_lb_backend_address_pool_address" "backend-address-ipv6" {
  count                   = var.instances > 1 ? var.instances : 0
  name                    = "backend-address-ipv6-%{if var.instances > 1}-${count.index}%{endif}"
  backend_address_pool_id = azurerm_lb_backend_address_pool.backend-address-Pool[0].id
  virtual_network_id      = var.vn ? azurerm_virtual_network.vm[0].id : data.azurerm_virtual_network.vm[0].id
  ip_address              = azurerm_network_interface.vm-outside[count.index+1].private_ip_address
}

我得到了以下错误：

count.index is 1
The given key does not identify an element in this collection value: the given index is greater than or equal to the length of the collection.

能够让它和这个陈述一起工作。多亏了Marko ip_address = azurerm_network_interface.vm-outside[count.index].private_ip_addresses[1]
