如何创建N个VM，每个VM创建并附加M个磁盘? [英] How do I create N VMs with M disks created and attached per VM?

问题描述

resource "azurerm_windows_virtual_machine" "virtual_machine" { 
    count = var.vm_count 
    name  = "${local.vm_name}${count.index +1}"

resource "azurerm_virtual_machine_data_disk_attachment" "datadisk01" {
    count              = var.disk_count  
    **virtual_machine_id = azurerm_windows_virtual_machine.virtual_machine[count.index].id
    managed_disk_id    = element("${module.DISK.datadisk_id}","${count.index}")

}

问题-我有2个差异计数变量vm_count和disk_count.我想要一个通用的解决方案，例如.如果虚拟机计数为2，并且每个虚拟机应具有3个数据磁盘，即disk_count为3.

Issue - I have 2 diffenent count varaibles vm_count and disk_count. I want a generic solution, Ex. If vm count is 2 and each VM should have 3 datadisk i.e. disk_count is 3.

我能够根据计数创建多个VM和磁盘.但是在vm和磁盘附件时遇到问题，因为我无法在同一资源中使用2个计数.如何处理这种情况?

I am able to create multiple VMs and Disks as per the count. But facing issue while vm and disk attachment, as i am not able to use 2 counts in same resource. How to handle this situation?

面对的问题设为**

总而言之，我想创建vm_count(N)个虚拟机，并创建disk_count(M)个磁盘并将其附加到每个虚拟机.

In summary, I want to create vm_count (N) VMs, with disk_count (M) disks created and attached to each VM.

如何创建N个VM，每个VM创建并附加M个磁盘?

How do I create N VMs with M disks created and attached per VM?

推荐答案

您可以使用一组索引来实现以下目的:

You can achieve something like this using a set of indexes:

locals {

  indexes = {
    for vmi in range(var.vm_count): vmi => [
      for ddi in range(var.disk_count):
        ddi
    ]
  }

}

这将创建这样的地图:

{
  "0" = [
    0,
    1,
    2,
  ]
  "1" = [
    0,
    1,
    2,
  ]
}

以后以这种方式使用:

resource "azurerm_virtual_machine_data_disk_attachment" "datadisk01" {
    for_each = local.indexes

    virtual_machine_id = azurerm_windows_virtual_machine.virtual_machine[tonumber(each.key)].id
    managed_disk_id    = element("${module.DISK.datadisk_id}","${each.value[0]}")
}

我还没有完全测试输出，因为VM需要更多配置.但是，正如我所看到的，您将 locals 用于 vm_name ，我将使用VM名称(包含索引，值和所需的磁盘)创建一个映射/对象.

I haven't fully tested the output as the VM needs more configuration. However as I can see you are using locals for vm_name I would create a map/object with VM names containing the index, the values and the desired disks.

我希望这有助于解决问题.

I hope this help resolve the issue.
