terraform for_each 不适用于展平数据

Question

我正在尝试使用 for_each 迭代一些扁平数据。我得到的输出看起来是正确的，但在迭代它时我遗漏了一些东西。见下图：

地形：

## LOCALS ##
locals {
  alternate_contacts = {
    contacts = {
      title         = "yes"
      contact_type  = ["BILLING", "OPERATIONS", "SECURITY"]
      aws_account   = ["12345", "67891", "11213"]
      email_address = ["[email protected]", "[email protected]", "[email protected]"]
      name          = ["bills", "ops", "sec"]
      phone_number  = "123456789"
    }
  }

  all_aws_accounts = flatten([
    for key, contacts in local.alternate_contacts : [
      for acc_id in contacts.aws_account : {
        contacts = contacts
        acc_id   = acc_id
      }
    ]
  ])

  accounts = { for v in local.all_aws_accounts : "${v.acc_id}" => v }
}

## RESOURCE ##

resource "aws_account_alternate_contact" "alternate_contacts" {
  for_each = local.accounts

  alternate_contact_type = each.value.contacts.contact_type

  name          = each.value.contacts.name
  title         = each.value.contacts.title
  email_address = each.value.contacts.email_address
  phone_number  = each.value.contacts.phone_number
  account_id    = each.key
}

输出：

Changes to Outputs:
  + all_aws_accounts = {
      + "11213" = {
          + acc_id   = "11213"
          + contacts = {
              + aws_account   = [
                  + "12345",
                  + "67891",
                  + "11213",
                ]
              + contact_type  = [

                  + "OPERATIONS",
                  + "SECURITY",
                ]
              + email_address = [
                  + "[email protected]",
                  + "[email protected]",
                  + "[email protected]",
                ]
              + name          = [
                  + "bills",
                  + "ops",
                  + "sec",
                ]
              + phone_number  = "123456789"
              + title         = "yes"
            }
        }
      + "12345" = {
          + acc_id   = "12345"
          + contacts = {
              + aws_account   = [
                  + "12345",
                  + "67891",
                  + "11213",
                ]
              + contact_type  = [
                  + "BILLING",
                  + "OPERATIONS",
                  + "SECURITY",
                ]
              + email_address = [

                  + "[email protected]",
                ]
              + name          = [
                  + "bills",
                  + "ops",
                  + "sec",
                ]
              + phone_number  = "123456789"
              + title         = "yes"
            }
        }
      + "67891" = {
          + acc_id   = "67891"
          + contacts = {
              + aws_account   = [
                  + "12345",
                  + "67891",
                  + "11213",
                ]
              + contact_type  = [
                  + "BILLING",
                  + "OPERATIONS",
                  + "SECURITY",
                ]
              + email_address = [
                  + "[email protected]",
                  + "[email protected]",
                  + "[email protected]",
                ]
              + name          = [
                  + "bills",
                  + "ops",
                  + "sec",

              + title         = "yes"
            }
        }
    }

错误：

我已经看过这个关于迭代的解释： 如何在 Terraform 0.12 中通过列表（对象）for_each 但似乎就是做不到。

请帮助我理解我在这里做错了什么

对我来说，输出看起来不正确，所有这些都是不合适的属性值，
如果我们查看文档：
https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/account_alternate_contact

不知道为什么你在

alternate_contacts

中有这样的结构......
但我假设这些列表中的 3 个元素应该被视为 CSV，如果是这种情况，代码看起来会非常不同，不需要展平。

locals {
  alternate_contacts = {
    contacts = {
      title         = "yes"
      contact_type  = ["BILLING", "OPERATIONS", "SECURITY"]
      aws_account   = ["12345", "67891", "11213"]
      email_address = ["[email protected]", "[email protected]", "[email protected]"]
      name          = ["bills", "ops", "sec"]
      phone_number  = "123456789"
    }
  }

  accounts = {
    for k, v in local.alternate_contacts.contacts.aws_account : v => {
      aws_account  = v
      title        = local.alternate_contacts.contacts.title
      phone_number = local.alternate_contacts.contacts.phone_number
      contact_type  = local.alternate_contacts.contacts.contact_type[k]
      email_address = local.alternate_contacts.contacts.email_address[k]
      name          = local.alternate_contacts.contacts.name[k]
    }
  }
}

output "accounts" {
  value = local.accounts
}

如果我们对此制定地形计划，我们会得到：

Changes to Outputs:
  + accounts = {
      + "11213" = {
          + aws_account   = "11213"
          + contact_type  = "SECURITY"
          + email_address = "[email protected]"
          + name          = "sec"
          + phone_number  = "123456789"
          + title         = "yes"
        }
      + "12345" = {
          + aws_account   = "12345"
          + contact_type  = "BILLING"
          + email_address = "[email protected]"
          + name          = "bills"
          + phone_number  = "123456789"
          + title         = "yes"
        }
      + "67891" = {
          + aws_account   = "67891"
          + contact_type  = "OPERATIONS"
          + email_address = "[email protected]"
          + name          = "ops"
          + phone_number  = "123456789"
          + title         = "yes"
