将动态嵌套列表输入terraform setproduct（）函数

问题：

bar = [
  [
    {"honda" = "passport"},
    {"toyota" = "prius"}
  ],
  [
    {"honda" = "civic"},
    {"toyota" = "prius"}
  ]
]

我有一个动态嵌套列表，我想输入到terraform函数中。我不能将嵌套列表直接传递给setproduct（）函数，也不能使用for循环在setproduct（）函数中迭代嵌套列表（请参见第节）。setproduct（）函数仅在我显式定义2个或多个单级列表参数时才起作用（请参见预期输出部分）

输入：（子列表是动态创建的，这意味着子列表索引范围会发生变化）

预期输出：

bar = [
  [
    {"honda" = "passport"},
    {"toyota" = "prius"}
  ],
  [
    {"honda" = "civic"},
    {"toyota" = "prius"}
  ]
]

可以使用下面的输出块创建预期的输出。尽管如问题部分所述，local.foo嵌套列表具有动态的第二级索引范围。因此，明确定义

[0]

和

[1]

标记并不是一个可行的解决方案

output "bar" {
  value = setproduct(local.foo[0], local.foo[1])
}

尝试：

bar = [
  [
    {"honda" = "passport"},
    {"toyota" = "prius"}
  ],
  [
    {"honda" = "civic"},
    {"toyota" = "prius"}
  ]
]

#1

output "bar" {
  value = setproduct(local.foo)
}

输出错误：

on test.tf line 35, in output "attempts":
  35:     value = setproduct(local.foo)
    |----------------
    | local.foo is tuple with 2 elements

Call to function "setproduct" failed: at least two arguments are required.

  35:     value = setproduct(local.foo[*])

#2

output "bar" {
  value = setproduct(local.foo[*])
}

输出错误：

  35:     value = setproduct(local.foo)
    |----------------

我想你在追求：

直到现在才知道TF DSL有一个“splat”类型的操作符。@MattSchuchard它可能非常简单：-）当然，我们需要注意术语，因为它在地形中已经意味着其他东西了D
