terraform - for_each 中带有动态块的 Terraform 错误

问题描述

我正在尝试使用 azuremrm 资源storage_share实例化一个 azure storage_share 地图。按照设计，我需要能够用同一个块实例化多个存储共享；这些股票中的每一个都可能有也可能没有“acl”部分。

我正在考虑将 for_each 与动态块结合使用来解决此问题，如相关的 SE 问题中所示：

主文件

resource "azurerm_storage_share" "storage_share" {
  for_each             = var.storage_share_map
  name                 = each.key
  storage_account_name = azurerm_storage_account.sa.name
  quota                = each.value.quota

  dynamic "acl" {
    for_each = each.value.acl
    content {
      id = acl.value.id

      access_policy {
        permissions = acl.value.access_policy.permissions
        start       = acl.value.access_policy.start
        expiry      = acl.value.access_policy.expiry
      }
    }
  }

该变量将被定义为：

variable "storage_share_map" {
  type = map(object({
    quota = number,
    acl = object({
      id = string,
      access_policy = object({
        expiry      = string,
        permissions = string,
        start       = string
      })
    }),
  }))
  default     = {}
}

后来在我的测试中参数化为：

storage_share_map = { 
  my-share-2 = {
    quota = 123,
    acl = {
      id = "a-id",
      access_policy = {
        expiry      = "ISO8061 UTC TIME"
        permissions = "rwdl"
        start       = "ISO8601 UTC TIME"
      },
    },
  }

但是，在测试时，terraform 返回以下输出：

Error: Unsupported attribute

  on .terraform\modules\sa\main.tf line 83, in resource "azurerm_storage_share" "storage_share":
  83:       id = acl.value.id
    |----------------
    | acl.value is object with 3 attributes

This object does not have an attribute named "id".


Error: Unsupported attribute

  83:       id = acl.value.id

This value does not have any attributes.


Error: Unsupported attribute

  on .terraform\modules\sa\main.tf line 86, in resource "azurerm_storage_share" "storage_share":
  86:         permissions = acl.value.access_policy.permissions
    |----------------
    | acl.value is object with 3 attributes

This object does not have an attribute named "access_policy".


Error: Unsupported attribute

  on .terraform\modules\sa\main.tf line 86, in resource "azurerm_storage_share" "storage_share":
  86:         permissions = acl.value.access_policy.permissions
    |----------------
    | acl.value is "a-id"

This value does not have any attributes.

据我了解，这里的问题是动态块内的 for_each 格式错误或行为不端：acl.value 似乎既被视为字符串“a-id”，又带有三个属性（？）。

Terraform版本 0.12.26 Azurerm版本 2.26.0

任何见解将不胜感激。

解决方案

请使用方括号each.value.acl。

Azure 存储共享块应如下所示：

resource "azurerm_storage_share" "storage_share" {
  for_each             = var.storage_share_map
  name                 = each.key
  storage_account_name = azurerm_storage_account.sa.name
  quota                = each.value.quota

  dynamic "acl" {
    for_each = [each.value.acl]
    content {
      id = acl.value.id

      access_policy {
        permissions = acl.value.access_policy.permissions
        start       = acl.value.access_policy.start
        expiry      = acl.value.access_policy.expiry
      }
    }
  }
}
