我们可以使用“计数”循环在可用性集中创建多个 azure vm。

我们如何使用“for_each”循环创建相同的主机名和网络接口 ID 将是动态和循环的。(地形 > 0.12.6)

resource "azurerm_virtual_machine" "test" {

 # user provides inputs only for the number of vms to be created in the Azure avaialibility set

 count                 = var.count 
 name                  = "acctvm${count.index}"
 location              = azurerm_resource_group.test.location
 availability_set_id   = azurerm_availability_set.avset.id
 resource_group_name   = azurerm_resource_group.test.name
 network_interface_ids = [element(azurerm_network_interface.test.*.id, count.index)]
 vm_size               = "Standard_DS1_v2"
 tags                  = var.tags

For-each 需要一个集合来循环。我假设您使用变量作为输入,所以

variable "vms" {
  type = list(string)
  default = ["alpha", "beta"]
}

variable "vms_data" {
  type = map(map(string))
  default = {
    alpha = {
      hostname = "alpha"
      interfaceid = "01"
    }
    alpha = {
      hostname = "beta"
      interfaceid = "02"
    }
  }
}

resource "azurerm_virtual_machine" "test" {
  for_each = toset(var.vms)

  name = var.vms_data[each.value].hostname
  location = azurerm_resource_group.test.location
  availability_set_id = azurerm_availability_set.avset.id
  resource_group_name = azurerm_resource_group.test.name
  network_interface_ids = [
    element(azurerm_network_interface.test.*.id, var.vms_data[each.value].interfaceid)]
  vm_size = "Standard_DS1_v2"
  tags = var.tags
}

但它尚未在 Azure 中实现(v. 12.23)。我有一个错误The name "for_each" is reserved for use in a future version of Terraform.

您可以在对象列表中指定所需的 VM 属性,然后使用for_each如下循环:

variable "VirtualMachines" {
  type = list(object({
    hostname= string
    interfaceid = string 
  }))
  default = [
    {
        hostname= "VM01",
        interfaceid = "01"
    },
     {
        hostname= "VM02",
        interfaceid = "02"
    }
  ]
}
    
resource "azurerm_virtual_machine" "test" {

  for_each = {for vm in var.VirtualMachines: vm.hostname => vm}

  name =  each.value.hostname
  location = azurerm_resource_group.test.location
  availability_set_id = azurerm_availability_set.avset.id
  resource_group_name = azurerm_resource_group.test.name
  network_interface_ids = [each.value.interfaceid]
  vm_size = "Standard_DS1_v2"
  tags = var.tags
}
