如何访问Terraform中for_each循环中映射中的序列

Question

使用Terraform，我有一个定义为变量的映射列表。

storage_accounts = {

  stacctest1 = {
    resource_group_name      = "testrg",
    location                 = "uksouth",
    account_tier             = "Standard",
    account_replication_type = "GRS",
    containers_list = [
      { name = "test_private_x", access_type = "private" },
      { name = "test_blob_x", access_type = "blob" },
      { name = "test_container_x", access_type = "container" }
    ]
  }

  stacctest2 = {
    resource_group_name      = "testrg",
    location                 = "uksouth",
    account_tier             = "Standard",
    account_replication_type = "GRS",
    containers_list = [
      { name = "test_private_a", access_type = "private" },
      { name = "test_blob_a", access_type = "blob" },
      { name = "test_container_a", access_type = "container" }
    ]    
  }

} 

然后在一个模块中，我可以使用一个for_each循环来遍历列表中的每一项来创建每个存储帐户。

resource "azurerm_storage_account" "storage" {
  for_each = var.storage_accounts

  name                     = each.key
  resource_group_name      = each.value.resource_group_name
  location                 = each.value.location
  account_tier             = each.value.account_tier
  account_replication_type = each.value.account_replication_type
  }
}

为了处理映射中的容器序列，我在想，我可以通过列表循环再一次处理容器，但很难找到如何将嵌套的循环与资源"azurerm_storage_container“相匹配。

你必须把压平你的变量。例如：

locals {
  flat_storage_accounts = merge([
    for account_name, details in var.storage_accounts: {
        for container in details.containers_list: 
          "${account_name}-${container.name}" => 
            merge(details, {
                "account_name" = account_name
                "container" = container
                })
      }
  ]...)
}

然后

resource "azurerm_storage_account" "storage" {
  for_each = local.flat_storage_accounts

  name                     = each.account_name
  resource_group_name      = each.value.resource_group_name
  location                 = each.value.location
  account_tier             = each.value.account_tier
  account_replication_type = each.value.account_replication_type

  # use individual container_list as
  # some_attribute         = each.value.container.access_type

  }

您还没有提供想要使用containers_list的代码，所以我只能在上面发表评论。
