Terraform无法在德国中西部区域创建Azure VM求助

问题详情 #

尝试在Germany West Central（德国中西部）区域创建Azure虚拟机时，触发如下错误：

Error: compute.VirtualMachinesClient#CreateOrUpdate: Failure sending request: StatusCode=0 -- Original Error: autorest/azure: Service returned an error. Status= Code="SkuNotAvailable" Message="The requested size for resource '/subscriptions//resourceGroups/shared-rg/providers/Microsoft.Compute/virtualMachines/jumphost' is currently not available in location 'germanywestcentral' zones '' for subscription ''. Please try another size or deploy to a different location or zones. See https://aka.ms/azureskunotavailable for details."

on modules/virtual-machine/main.tf line 1, in resource "azurerm_virtual_machine" "vm":
1: resource "azurerm_virtual_machine" "vm" {

使用的VM规格为Standard_A1_v2，操作系统SKU为22.04-LTS。

Terraform代码 #

变量配置 #

jump_host_vm_name = "jumphost"
jump_host_vm_size = "Standard_A1_v2"
jump_host_storage_image_reference = {
  publisher = "Canonical"
  offer     = "UbuntuServer"
  sku       = "22.04-LTS"
  version   = "latest"
}
jump_host_storage_os_disk = {
  name              = "myosdisk"
  caching           = "ReadWrite"
  create_option     = "FromImage"
  managed_disk_type = "Standard_LRS"
}

疑问 #

根据Azure官网显示，Standard_A1_v2规格在德国区域是可用的，为什么创建会失败？

问题解答 #

导致该错误的常见原因及对应解决办法如下：

• 订阅级配额/可用性限制：Azure官网显示的区域可用性是全局层面，但你的订阅可能在该区域没有Standard_A1_v2的配额，或是该SKU在当前订阅下暂时资源耗尽。可通过Azure CLI查询当前订阅的SKU状态：

  az vm list-skus --location germanywestcentral --size Standard_A1_v2 --output table
  

  若结果显示NotAvailableForSubscription，可提交配额提升申请。
• 资源组所在分区库存不足：即使区域整体支持该SKU，你创建VM的资源组对应的具体可用区（或无可用区）可能暂时无库存。可尝试指定可用区（如在VM资源中添加zones = ["1"]），或更换同系列其他规格（如Standard_A2_v2）。
• 临时区域资源短缺：Azure区域资源供应可能存在临时波动，间隔一段时间重试创建操作可能成功。
• 参数核对：检查代码注释与实际变量值的一致性（代码注释写的是20.04-LTS，但变量是22.04-LTS），确认Terraform执行时实际使用的参数正确。
