使用Terraform将NIC附加到Azure中正在运行的VM

我写了一个Terraform脚本在Azure中部署VM。我想在不同时间将多个NIC附加/分离到该VM。 由于虚拟机在部署后开始运行,因此当我尝试向network_interface_ids资源块内的azurerm_virtual_machine添加另一个NIC ID时出现错误。 我认为Terraform尚无法更改Azure中VM的状态。 没有在Terraform中看到任何VM-NIC关联资源,该如何实现?

我是接触云和地形的初学者,所以这可能是一个基本问题,但是我在任何地方都找不到解决方案。任何帮助表示赞赏。

我当前的代码如下:

resource "azurerm_network_interface" "nic1" {
  name = "nic1"
  resource_group_name = data.azurerm_resource_group.rg.name
  location = data.azurerm_resource_group.rg.location
  enable_accelerated_networking = true
  ip_configuration {
    name = "nic1-config1"
    # public_ip_address_id = azurerm_public_ip.public_ip.id
    private_ip_address_allocation = "dynamic"
    subnet_id = data.azurerm_subnet.subnet.id
    primary = true

  }
  ip_configuration {
    name = "nic1-config2"
    public_ip_address_id = azurerm_public_ip.public_ip.id
    private_ip_address_allocation = "dynamic"
    subnet_id = data.azurerm_subnet.subnet.id
  }
  tags =  var.TAGS
}



 resource "azurerm_network_interface" "nic2" {
  name = "nic2"
  resource_group_name = data.azurerm_resource_group.rg.name
  location = data.azurerm_resource_group.rg.location
  enable_accelerated_networking = true
  ip_configuration {
    name = "nic2-config1"
    # public_ip_address_id = azurerm_public_ip.public_ip.id
    private_ip_address_allocation = "dynamic"
    subnet_id = data.azurerm_subnet.subnet.id
    primary = true

  }
  ip_configuration {
    name = "nic2-config2"
    # public_ip_address_id = azurerm_public_ip.public_ip.id
    private_ip_address_allocation = "dynamic"
    subnet_id = data.azurerm_subnet.subnet.id
  }
  tags =  var.TAGS
}


resource "azurerm_virtual_machine" "vm" {
  name = "vm"
  resource_group_name = data.azurerm_resource_group.rg.name
  location = data.azurerm_resource_group.rg.location
  network_interface_ids = [azurerm_network_interface.nic1.id]
  vm_size = "Standard_D4S_v3"
  delete_os_disk_on_termination = true
  delete_data_disks_on_termination = true
  storage_os_disk {
    name = "os-disk"
    create_option = "FromImage"
    caching = "ReadWrite"
    managed_disk_type = "Premium_LRS"
    disk_size_gb = 32
  }

  primary_network_interface_id = azurerm_network_interface.nic.id
  
  storage_image_reference {
    id = lookup(var.VMI,data.azurerm_resource_group.rg.location)
  }


  os_profile {
    admin_username = "test"
    computer_name = "test"
    admin_password = "test"
  }
  os_profile_linux_config {
    disable_password_authentication = true


    ssh_keys {
      path = "/home/user/.ssh/authorized_keys"
      key_data = "..."
    }
  }
  tags =  var.TAGS
  
}

我成功部署了上述基础架构。

现在,我要将 nic2 附加到该虚拟机,因此进行了以下更改

resource "azurerm_virtual_machine" "vm" {
....
  network_interface_ids = [azurerm_network_interface.nic1.id, azurerm_network_interface.nic2.id]
...
}

https://azure.microsoft.com/en-us/blog/introducing-the-new-dv3-and-ev3-vm-sizes说我最多可以将两个NIC连接到Standard_D4s_v3。

我收到此错误,明确表示关闭虚拟机,然后尝试附加。

错误:compute.VirtualMachinesClient#CreateOrUpdate代码=“ AddingOrDeletingNetworkInterfacesOnARunningVirtualMachineNotSupported” Message =“具有单个网络接口的虚拟机vm必须先停止释放,然后才能更新为具有多个网络接口,反之亦然。”

我想知道是否可以通过某种方式将NIC热连接到VM上吗?

将另一个NIC附加到现有VM时,VM必须处于已停止(已取消分配)状态。它是设计的。而且Terraform没有用于VM与NIC之间关联的单独资源。

因此,据我所知,无论如何,您首先需要停止虚拟机,然后将第二个nic id添加到虚拟机中。

resource "azurerm_virtual_machine" "vm" {
....
  network_interface_ids = [azurerm_network_interface.nic1.id, azurerm_network_interface.nic2.id]
...
}

VM处于停止状态时,然后应用Terraform代码。要通过Terraform停止VM,可以使用null_resource with local-exec provisioner执行CLI命令:

resource "null_resource" "example2" {
  provisioner "local-exec" {
    command = "az vm stop --resource-group groupName --name vmName"
    interpreter = ["/bin/bash", "-c"]
  }
}
