Attach disks to multiple VMs using Terraform

问题

  1. I want to attach disks of different sizes to a particular VM. My code is as follows. 
  2. "Virtual_machine_id" was imported through for loop, but could not be written.
  3. My "output" works fine, but it actually causes problems with the "terraform plan".
  5. - manageddisk.tf
  6. ```plaintext
  7. 我想将不同大小的磁盘附加到特定的虚拟机上。我的代码如下。
  8. "Virtual_machine_id" 是通过循环导入的，但无法编写。
  9. 我的"output"工作正常，但实际上会导致"terraform plan"出现问题。
  11. - manageddisk.tf

  1. 然而，virtual_machine_id 是问题所在。

Successfully attaches disk by acquiring "virtual_machine_id".

  1. 通过获取"virtual_machine_id"成功附加磁盘。

I succeeded with the code below. But not yet.

你基本上需要一个双重循环，在使用之前需要将其展开：

  1. locals {
  2.   disk_vm_flat = merge([
  3.     for vm, vm_vals in var.vm_template : {
  4.       for disk, disk_vals in var.disk_template :
  5.         "${vm_vals.vm_name}-${disk_vals.managed_disk_name}" => {
  6.             vm_name = vm
  7.             managed_disk_name = disk
  8.             managed_disk_size = disk_vals.managed_disk_size
  9.         } if disk_vals.managed_disk_size != "0"
  10.     }
  11.   ]...) # 不要删除这些点，它们很重要
  12. }

然后

  1. resource "azurerm_virtual_machine_data_disk_attachment" "disk_attach" {
  2.   for_each           = local.disk_vm_flat
  3.   managed_disk_id    = azurerm_managed_disk.managed_disk[each.value.managed_disk_name].id
  4.   lun                = each.value.managed_disk_size
  5.   caching            = "ReadWrite"
  6.   virtual_machine_id   = data.azurerm_virtual_machine.vm_id[each.value.vm_name].id
  7. }
英文:

You basically need a double for loop, which you need to flatten first before the use:

  1. locals {
  2.   disk_vm_flat = merge([
  3.     for vm, vm_vals in var.vm_template:  {
  4.       for disk, disk_vals in var.disk_template:
  5.         "${vm_vals.vm_name}-${disk_vals.managed_disk_name}" => {
  6.             vm_name = vm
  7.             managed_disk_name = disk
  8.             managed_disk_size = disk_vals.managed_disk_size
  9.         }  if disk_vals.managed_disk_size != "0"
  10.     }
  11.   ]...) # do NOT remove the dots. they are important
  12. }

then

  1. resource "azurerm_virtual_machine_data_disk_attachment" "disk_attach" {
  2.   for_each           = local.disk_vm_flat
  3.   managed_disk_id    = azurerm_managed_disk.managed_disk[each.value.managed_disk_name].id
  4.   lun                = each.value.managed_disk_size
  5.   caching            = "ReadWrite"
  6.   virtual_machine_id   = data.azurerm_virtual_machine.vm_id[each.value.vm_name].id
  7. }
