无法通过 terraform 为 Azure 虚拟机设置动态 IP

Question

不确定哪里出了问题，但我无法使以下代码正常工作。

目标：创建两个（或更多）具有公共 IP 的虚拟机。

问题：遇到 terraform plan 报告错误，如错误代码块所示。

Terraform 代码块如下：

resource "azurerm_public_ip" "tf-pubip-cluster-aos" {
    count                        = 2
    name                         = "${var.ax_base_hostname}-${count.index+1}-PUBIP"
    location                     = "${azurerm_resource_group.tf-rg-cluster-aos.location}"
    resource_group_name          = "${azurerm_resource_group.tf-rg-cluster-aos.name}"
    allocation_method            = "Dynamic"
}

resource "azurerm_network_interface" "tf-ni-cluster-aos" {
 count               = 2
 name                = "${var.ax_base_hostname}-${count.index+1}-NI"
 location            = "${azurerm_resource_group.tf-rg-cluster-aos.location}"
 resource_group_name = "${azurerm_resource_group.tf-rg-cluster-aos.name}"

ip_configuration {
    name                          = "${var.ax_base_hostname}-${count.index+1}-IP"
    subnet_id                     = "${data.azurerm_subnet.tf-sn-cluster-aos.id}"
    private_ip_address_allocation = "Dynamic"
    public_ip_address_id          = "${azurerm_public_ip.tf-pubip-cluster-aos.id}"
}
}
resource "azurerm_virtual_machine" "tf-vm-cluster-aos" {
  count                 = 2
  name                  = "${var.ax_base_hostname}-${count.index+1}"
  location            = "${azurerm_resource_group.tf-rg-cluster-aos.location}"
  resource_group_name = "${azurerm_resource_group.tf-rg-cluster-aos.name}"
  availability_set_id   = "${azurerm_availability_set.tf-as-cluster-aos.id}"
  network_interface_ids = ["${element(azurerm_network_interface.tf-ni-cluster-aos.*.id, count.index)}"]
  vm_size               = "${var.ax_vm_size}"

}

错误信息如下：

Error running plan: 1 error(s) occurred:

    azurerm_network_interface.tf-ni-cluster-aos: 2 error(s) occurred:
    azurerm_network_interface.tf-ni-cluster-aos[0]: Resource 'azurerm_public_ip.tf-pubip-cluster-aos' not found for variable 'azurerm_public_ip.tf-pubip-cluster-aos.id'
    azurerm_network_interface.tf-ni-cluster-aos[1]: Resource 'azurerm_public_ip.tf-pubip-cluster-aos' not found for variable 'azurerm_public_ip.tf-pubip-cluster-aos.id'

想不通...任何帮助都会很棒。

您创建了 2 个公共 ip，而不是一个，但您尝试引用它，就像它是单个 ip 一样，但事实并非如此。它是一个列表。您需要获取个人公共 ip id，如下所示：

"${element(azurerm_public_ip.tf-pubip-cluster-aos.*.id, count.index)}"
