Terraform：如何迭代通过json文件输入的地图的键值对

如何解决Terraform：如何迭代通过json文件输入的地图的键值对

这是我输入的json文件：

{
  "inputs": [
        {
          "acct_id": "foo-bar-15","display_name": "foo bar","project-role-pairs": {"test-1234": "roles/logging.logWriter","test-2345": "roles/storage.objectViewer"}
        },{
          "acct_id": "foo-bar-16","display_name": "john doe","project-role-pairs": {"test-3456": "roles/logging.logWriter","test-4567": "roles/storage.objectViewer"}
        }
      ]
}

代码：这是我的代码，基于输入在GCP中创建服务帐户（该部分工作正常）。它还尝试根据上面的json文件中的project-roles-pairs映射在2个项目中创建IAM角色。我无法浏览地图。我根本不知道为什么。就目前而言，代码只是将映射中的第一个键用于两者，就好像没有第二对键值一样。我一直在寻找“扁平化”的动态块和setproduct。它们似乎不适合用例，或者我无法有效使用它们。请帮忙。

locals {
  json_data_7 = jsondecode(file("./data7.json"))
}


# Creates a Service Account for each top level in input
resource "google_service_account" "service_accounts_for_each_7" {
  for_each = {for v in local.json_data_7.inputs: v.acct_id => v.display_name}
  account_id   = each.key
  display_name = each.value
}

# 
resource "google_project_iam_member" "rolebinding" {
  for_each     = { for v in local.json_data_7.inputs: v.acct_id => v }
  project = element(keys(each.value.project-role-pairs),0)  #ONLYfirst key in MAP,not what I want,I would like this part loop through map and create a role for each KV-pair in JSON input
  role    = lookup(each.value.project-role-pairs,element(keys(each.value.project-role-pairs),0))
  member  = "serviceAccount:${google_service_account.service_accounts_for_each_7[each.key].email}"
}

问题：

如何使我的代码遍历JSON文件中输入的两个键值对：project-roles-pairs？谢谢。

解决方法

如果我理解正确，则需要在inputs和project-role-pairs上进行两次迭代。因此，您可以首先创建一个helper_list，如下所示：

locals {

  helper_list = flatten([ for v in local.json_data_7.inputs: 
            [ for project,role in v.project-role-pairs:
             { "project" = project
               "role" = role
                acct_id = v.acct_id
                display_name = v.display_name}
            ]
          ])
}

以上将导致helper_list为：

[
  {
    "acct_id" = "foo-bar-15"
    "display_name" = "foo bar"
    "project" = "test-1234"
    "role" = "roles/logging.logWriter"
  },{
    "acct_id" = "foo-bar-15"
    "display_name" = "foo bar"
    "project" = "test-2345"
    "role" = "roles/storage.objectViewer"
  },{
    "acct_id" = "foo-bar-16"
    "display_name" = "john doe"
    "project" = "test-3456"
    "role" = "roles/logging.logWriter"
  },{
    "acct_id" = "foo-bar-16"
    "display_name" = "john doe"
    "project" = "test-4567"
    "role" = "roles/storage.objectViewer"
  },]

随后，您的google_project_iam_member可能是：

resource "google_project_iam_member" "rolebinding" {
  for_each     = { for idx,v in local.helper_list: idx => v }
  project = each.value.project
  role    = each.value.role
  member  = "serviceAccount:${google_service_account.service_accounts_for_each_7[each.value.acct_id].email}"
}

请注意，由于我通常不使用GCP，因此上述内容可能需要进行调整，因此无法验证google_project_iam_member的外观。
