azure - Terraform:即使添加了第 6 个和第 7 个属性，each.value 也是具有 5 个属性的对象

Question

我正在尝试将几个设置(is_hns_enabled 和 account_kind)添加到 2 个现有存储帐户，同时创建第三个。 2个exisint只需要明确说明这些设置的默认值。在这两个新设置上，所有 3 个帐户都遇到以下错误。这是错误的 1 个实例

错误:

│ Error: Invalid index
│ 
│   on storage.tf line 48, in resource "azurerm_storage_account" "storage-account":
│   48:   is_hns_enabled           = each.value["is_hns_enabled"]
│     ├────────────────
│     │ each.value is object with 5 attributes
│ 
│ The given key does not identify an element in this collection value.

存储帐户已存在，但我需要明确设置此设置以将其与其他帐户区分开。我将其设置为 false，这已经是默认值。

地形:

locals {
  containers = merge([
    for account, account_details in var.storage_accounts : {
      for container in account_details.containers :
      "${account}-${container["name"]}" => {
        "name"                 = container["name"]
        "access_type"          = container["access_type"]
        "storage_account_name" = account
      }
    }
  ]...)
  roles = merge([
    for account, account_details in var.storage_accounts : {
      for role in account_details.roles :
      "${account}-${role["objectId"]}" => {
        "storage_account_name" = account
        "objectId"             = role["objectId"]
        "storage_role"         = role["storage_role"]
      }
    }
  ]...)
}


resource "azurerm_storage_account" "storage-account" {
  for_each                 = var.storage_accounts
  name                     = substr(replace(lower(each.key), "/\\W|_|\\s/", ""), 0, 24)
  resource_group_name      = var.azure["resource_group_name"]
  location                 = var.azure["location"]
  account_tier             = each.value["account_tier"]
  account_kind             = each.value["account_kind"]
  is_hns_enabled           = each.value["is_hns_enabled"]
  account_replication_type = each.value["account_replication_type"]

  blob_properties {
    versioning_enabled = each.value["versioning_enabled"]
  }
}

TF，存储变量:

storage_accounts = {
  acct1 = {
    account_tier             = "Premium"
    account_kind             = "BlockBlobStorage"
    account_replication_type = "RAGRS"
    versioning_enabled       = false
    is_hns_enabled           = false
    roles                    = []
    containers = [
      {
        name        = "container1"
        access_type = "private"
      }
    ]
  }
}

Answer 1

The given key does not identify an element in this collection value.

解决此问题后，我发现了以下方法:

方法 1:

您可以包含coalesce()函数。函数coalesce() in terraform 返回其参数中的第一个非空值。因此，如果 each.value["is hnsenabled"] 为 null 或未定义，则将使用默认值 false。

is_hns_enabled = coalesce(each.value["is_hns_enabled"],false)

进行一些更改后，您的代码如下所示。

resource "azurerm_storage_account" "storage-account" {
  for_each                 = var.storage_accounts
  name                     = substr(replace(lower(each.key), "/\\W|_|\\s/", ""), 0, 24)
  resource_group_name      = "Jahnavi"
  location                 = "eastus"
  account_tier             = each.value["account_tier"]
  account_kind             = each.value["account_kind"]
  is_hns_enabled           = coalesce(each.value["is_hns_enabled"],false)
  account_replication_type = each.value["account_replication_type"]

  blob_properties {
    versioning_enabled = each.value["versioning_enabled"]
  }
}

方法 2:

或者，如果您尝试获取现有的存储帐户并设置所需的属性，请使用 data block 获取现有的存储帐户。

data "azurerm_storage_account" "example"{
name = "storageaccount"
location="eastus"
}

Terraform 已成功初始化且配置验证成功。
