Question

错误：括号不平衡

在 .terraform\modules\nics\main.tf 第 19 行，在资源“azurerm_network_interface”“NIC1”中： 19：subnet_id = "${element(var.subnetwork-subnetid.*.id, (0,1))}"

子网的输出值：

output "subnetwork-subnetid" {
  value = concat(azurerm_subnet.subnetwork.*.id, azurerm_subnet.subnetwork6.*.id)
}

nic.tf

resource "azurerm_network_interface" "NIC1" {
  #count = "${length(var.subnetwork-subnetid)}"
  #for_each= toset(var.subipv4)
  count = "${length(var.subipv4)}"
  name  = "${lookup(element(var.subipv4, count.index), "name")}"
  #name                = var.nic-name
  location                      = var.rg-location
  resource_group_name           = var.rg-name
  enable_ip_forwarding          = true
  enable_accelerated_networking = true
  ip_configuration {
    name                          = "ipconfig"
    subnet_id                     = "${element(var.subnetwork-subnetid.*.id, (0,1))}"
    private_ip_address_allocation = "Dynamic"
    #public_ip_address_id          = azurerm_public_ip.pubip.id
    #public_ip_address_id = azurerm_public_ip.pubip.*.id
    primary = true
  }
  tags = {
    name = "${lookup(element(var.subipv4, count.index), "name")}"
  }
}```

Please someone help me in this issue.Thanks!

element 中的第二个参数是 index：

<块引用>

index 查找特定元素值的索引。

因此要根据索引从列表中获取少量元素，您可以：

subnet_id = [ for idx in [0, 1]: element(var.subnetwork-subnetid.*.id, idx) ]

如果您想要范围的独立游戏，您可以使用slice：

subnet_id = slice(var.subnetwork-subnetid.*.id, 0, 2)

我已经创建了 4 个子网并创建了输出值以在一个变量中获取所有子网 ID。那么我如何计划检索 2 个值来附加 nics
