使用 Terraform 创建具有 IAM 角色的服务帐户

Question

我正在尝试roles/logging.logWriter使用 Terraform创建一个具有IAM 角色的基本服务帐户。下面是我如何配置这个：

resource "google_service_account" "log_user" {
  account_id   = "log-user"
  display_name = "Logging User"
}

data "google_iam_policy" "log_policy" {
  binding {
    role = "roles/logging.logWriter"

    members = [
      "serviceAccount:${google_service_account.log_user.email}"
    ]
  }
}

resource "google_service_account_iam_policy" "log_user_policy" {
  service_account_id = "${google_service_account.log_user.name}"
  policy_data        = "${data.google_iam_policy.log_policy.policy_data}"
}

运行时，terraform apply我收到以下错误消息：

* module.iam.google_service_account_iam_policy.log_user_policy: 1 error(s) occurred:

* google_service_account_iam_policy.log_user_policy: Error setting IAM policy for service account 'projects/arcadia-apps-237918/serviceAccounts/log-user@arcadia-apps-237918.iam.gserviceaccount.com': googleapi: Error 400: Role roles/logging.logWriter is not supported for this resource., badRequest

从我所做的挖掘中，我似乎无法找到关于如何创建服务帐户然后为其附加角色的明确解释。

Answer 1

我通过执行以下操作解决了这个问题：

resource "google_service_account" "log_user" {
  account_id   = "log-user"
  display_name = "Logging User"
}

resource "google_project_iam_binding" "log_user" {
  project = "arcadia-apps-237918"
  role    = "roles/logging.logWriter"
  members = [
    "serviceAccount:${google_service_account.log_user.email}"
  ]
}

terraform在您执行此操作之前，运行的用户需要为其分配 IAM 管理员角色。
