Question

我想用teraaform做这些事情。我将像10一样同时创建多个vms。我打算使用静态IP选项所以，让我们说我的IP开始于

192.168.5.4,192.168.5.5,192.168.5.6 ....等等

所以我想确保下面的IP应该进入相同的故障域。

说故障域0

192.168.5.4

192.168.5.7

192.168.5.10

说故障域1

192.168.5.5

192.168.5.8

192.168.5.11

说故障域2

192.168.5.6

192.168.5.9

192.168.5.12

关系是（lastnumber％3）是相同的。我怎么能做到这一点？

您可以使用simple math interpolation之类的内容：

variable "count" {
  default = 10
}

resource "azurerm_network_interface" "test" {
    name = "${format("VM%02d-NIC1", count.index + 1)}"
    location = "West US"
    resource_group_name = "myResourceGroup"
    count = "${var.count}"

    ip_configuration {
        name = "${format("ipConfig-VM%02d-NIC1", count.index + 1)}"
        subnet_id = "SubNet"
        private_ip_address_allocation = "Static"
        private_ip_address = "192.168.5.${count.index + 1}"
    }

    tags {
        fault_domain = "${(count.index + 1) % 3}"
    }
}

然后根据您的要求创建其余的基础架构，并将NIC分配给您的VM：

resource "azurerm_virtual_machine" "test" {
    count = "${var.count}"
    name = "${format("VM%02-test", cound.index + 1)}"
    location = "West US"
    resource_group_name = "myResourceGroup"
    network_interface_ids = ["${element(azurerm_network_interface.test, count.index).id}"]
    vm_size = "Standard_A0"
    ...
 }

将故障域绑定到azure和Terraform中的特定IP
