azure - Azure 上的 Terraform - 部署多个子网

Question

我正在尝试实现 Terraform 脚本来创建多个子网。

resource "azurerm_subnet" "test_subnet" {
    name = "testSUBNET"
    resource_group_name = "${local.resource_group_name}"
    virtual_network_name = "${azurerm_virtual_network.lab_vnet.name}"
    address_prefix = "10.0.1.0/24"
}

有没有办法对变量执行 for-each 或循环以便同时创建它们？

Answer 1

您可以使用变量和计数索引来实现此目的，如下所示:

variable "subnet_prefix" {
  type = "list"
  default = [
    {
      ip      = "10.0.1.0/24"
      name     = "subnet-1"
    },
    {
      ip      = "10.0.2.0/24"
      name     = "subnet-2"
    }
   ]
}

resource "azurerm_subnet" "test_subnet" {
    name = "${lookup(element(var.subnet_prefix, count.index), "name")}"
    count = "${length(var.subnet_prefix)}"
    resource_group_name = "${local.resource_group_name}"
    virtual_network_name = "${azurerm_virtual_network.lab_vnet.name}"
    address_prefix = "${lookup(element(var.subnet_prefix, count.index), "ip")}"
}

还有预览功能可用for-each在新版本中
