linux - 引用在 terraform 循环中创建的特定 public_ip

Question

我无法正确地将使用 terraform 创建的第一个 azure 公共(public) IP 引用到使用相同 terraform 脚本创建的网络安全组中。

我尝试了各种方法以使该行正常:

source_address_prefix      = "${(count.index == 0 ? var.incoming_ip : azurerm_public_ip.test.0.)}"

我尝试过:

azurerm_public_ip.test.0.name
azurerm_public_ip.test.0.ip_adress
azurerm_public_ip.test[0]

但是我在部署时遇到错误，它似乎将 null 或字符串传递给脚本，而不是使用 count.index 为 0 创建的第一个实例的 public_ip。

resource "azurerm_public_ip" "test" {
 name                         = "publicIP-${count.index}"
 location                     = "${var.regions[count.index]}"
 resource_group_name          = "${element(azurerm_resource_group.test.*.name, count.index)}"
 allocation_method            = "Static"
 count                        = "${length(var.regions)}"
 }

 resource "azurerm_network_security_group" "test" {
    name                = "${var.nameid[count.index]}"
    count               = "${length(var.regions)}"
    location            = "${var.regions[count.index]}"
    resource_group_name = "${element(azurerm_resource_group.test.*.name, count.index)}"

    security_rule {
        name                       = "SSH"
        priority                   = 1001
        direction                  = "Inbound"
        access                     = "Allow"
        protocol                   = "Tcp"
        source_port_range          = "*"
        destination_port_range     = "22"
        source_address_prefix      = "${var.incoming_ip}"
        destination_address_prefix = "*"
    }

    security_rule {
        name                       = "curl"
        priority                   = 1002
        direction                  = "Inbound"
        access                     = "Allow"
        protocol                   = "Tcp"
        source_port_range          = "*"
        destination_port_range     = "${(count.index == 0 ? 8888 : 7777)}"
        source_address_prefix      = "${(count.index == 0 ? var.incoming_ip : azurerm_public_ip.test.0.)}"
        destination_address_prefix = "*"
    }
}

我期待这一行:

source_address_prefix      = "${(count.index == 0 ? var.incoming_ip : azurerm_public_ip.test.0.name)}"

以这种方式行事:

如果 count.index == 0，则为 var.incoming_ip 的值，否则为在索引 0 处创建的 Azure 公共(public) IP 的值。

这个语法成功了:

source_address_prefix      = "${(count.index == 0 ? var.incoming_ip : element(azurerm_public_ip.test.*.ip_address, 0))}"
