通过 Terraform 使用 For_Each 循环创建 Azure VM

Question

我正在尝试通过 terrform 使用 for_each 创建多个 Azure VM，我能够创建 2 个 NIC 卡，但是在 zurerm_windows_virtual_machine block 中定义 NIC id 时，两个 VM 都选择相同的 NIC 卡(最后一个，索引 1)，结果是只有虚拟机正在创建，其他虚拟机失败。(network_interface_ids = azurerm_network_interface.az_nic[*].id) 的逻辑是什么:第一个虚拟机将选择第一个网卡，第二个虚拟机也这样做。

#---------------为 Windows VM 创建网络接口(interface) --------------

resource "azurerm_network_interface" "az_nic" {
  count               = length(var.vm_names)
  name                = "${var.vm_names[count.index]}_nic"
  location            = var.location
  resource_group_name = data.azurerm_resource_group.Resource_group.name


  ip_configuration {
    name                          = var.vm_names[count.index]
    subnet_id                     = data.azurerm_subnet.subnet.id
    private_ip_address_allocation = "Dynamic"
  }
}

resource "azurerm_windows_virtual_machine" "myvm" {
  for_each              = toset(var.vm_names)
  name                  = each.value
  resource_group_name   = data.azurerm_resource_group.Resource_group.name
  location              = var.location
  size                  = "Standard_D2s_v3"
  admin_username        = "abc"
  admin_password        = "uejehrikch123"
  network_interface_ids = azurerm_network_interface.az_nic[*].id
       
 
  source_image_reference {
    publisher = "MicrosoftWindowsServer"
    offer     = "WindowsServer"
    sku       = "2016-Datacenter"
    version   = "latest"
  }

  os_disk {
    caching              = "ReadWrite"
    storage_account_type = "Standard_LRS"
  }

Answer 1

您可以在资源“azurerm_windows_virtual_machine”中添加count参数，而不是混合使用count和for_each .

假设你有

variable "vm_names" {
  default = ["vm1", "vm2"]
}

然后你可以像这样更改资源.tf文件:

resource "azurerm_windows_virtual_machine" "myvm" {
  count                 = length(var.vm_names)
  name                  = element(var.vm_names,count.index)
  resource_group_name   = data.azurerm_resource_group.Resource_group.name
  location              = var.location
  size                  = "Standard_D2s_v3"
  admin_username        = "abc"
  admin_password        = "uejehrikch123"
  network_interface_ids =  [element(azurerm_network_interface.az_nic.*.id, count.index)]
       
 
  source_image_reference {
    publisher = "MicrosoftWindowsServer"
    offer     = "WindowsServer"
    sku       = "2016-Datacenter"
    version   = "latest"
  }

  os_disk {
    caching              = "ReadWrite"
    storage_account_type = "Standard_LRS"
  }
