Terraform 不能将 target_id 与 for_each 循环一起使用

Question

我们有用于创建存储帐户的代码：

resource "azurerm_storage_share" "storage_account_shares" {
  for_each             = var.storage_share
  name                 = each.value["name"]
  storage_account_name = replace("${var.resource_name_prefix}${each.value["account_name"]}", "-", "")
  quota                = each.value["quota"]
  enabled_protocol     = each.value["protocol"]
}

现在我需要为每个 storage_share 创建诊断设置：

    resource "azurerm_monitor_diagnostic_setting" "storagemain_logs" {
  for_each             = var.storage_share
  name       = "storagemain-logs"

  target_resource_id = azurerm_storage_share.storage_account_shares.id
  storage_account_id = azurerm_storage_account.storage_accounts.id

  dynamic "log" {
    iterator = entry
    for_each = local.storages_categories
    content {
        category = entry.value
        enabled  = true

        retention_policy {
            enabled = true
            days = 30
        }
    }

我不明白我应该在“target_resourse_id”中放入什么，以使其与我在 storage_share 资源中的“for_each”块交互工作。我试过这个变体，但没有用：

locals {
  storage_accounts_output = {
    id   = [for i in azurerm_storage_share.storage_account_shares : i.id]
  }
}

然后添加

target_resource_id = local.storage_accounts_output.id[index]

Answer 1

您需要使用

each.key

值来引用storage_account_shares

资源的实例

，像这样：

target_resource_id = azurerm_storage_share.storage_account_shares[each.key].id

或者，您可以使用 官方文档 中描述的 for_each 链接方法，将代码修改为如下所示：

resource "azurerm_monitor_diagnostic_setting" "storagemain_logs" {
  for_each   = azurerm_storage_share.storage_account_shares
  name       = "storagemain-logs"

  target_resource_id = each.value.id
