数据流设置控制器服务帐户

Question

我尝试为数据流设置控制器服务帐户。 在我的数据流选项中，我有：

options.setGcpCredential(GoogleCredentials.fromStream(
                         new FileInputStream("key.json")).createScoped(someArrays)); 
options.setServiceAccount("xxx@yyy.iam.gserviceaccount.com");

但我得到：

WARNING: Request failed with code 403, performed 0 retries due to IOExceptions,         
         performed 0 retries due to unsuccessful status codes, HTTP framework says 
         request can be retried, (caller responsible for retrying):

}

我是否缺少某些角色或权限？

Answer 1

也许有人会发现它有帮助：

• 对于控制器，它是：Dataflow Worker 和 Storage Object Admin（可在Google 的文档中找到）。

• 对于执行者，它是：服务帐户用户。

Answer 2

我一直遇到这个错误，并认为值得分享我的经验（部分原因是我怀疑我将来会再次遇到这种情况）。

创建我的数据流作业的地形代码是：

resource "google_dataflow_job" "wordcount" {
  # https://stackoverflow.com/a/59931467/201657
  name              = "wordcount"
  template_gcs_path = "gs://dataflow-templates/latest/Word_Count"
  temp_gcs_location = "gs://${local.name-prefix}-functions/temp"
  parameters = {
    inputFile = "gs://dataflow-samples/shakespeare/kinglear.txt"
    output = "gs://${local.name-prefix}-functions/wordcount/output"
  }
  service_account_email = "serviceAccount:${data.google_service_account.sa.email}"
}

错误信息：

错误：googleapi: 错误 400: (c3c0d991927a8658): 当前用户不能充当服务帐户 serviceAccount:dataflowdemo@redacted.iam.gserviceaccount.com., badRequest

从运行terraform apply返回。 查看日志提供了更多信息：

gcloud logging read 'timestamp >= "2020-12-31T13:39:58.733249492Z" AND timestamp <= "2020-12-31T13:45:58.733249492Z"' --format="csv(timestamp,severity,textPayload)" --order=asc

它返回了各种日志记录，包括：

控制器服务帐户的权限验证失败。 IAM 角色 roles/dataflow.worker 应授予控制器服务帐户 dataflowdemo@redacted.iam.gserviceaccount.com。

所以我授予了缺失的角色授予

gcloud projects add-iam-policy-binding $PROJECT \
  --member="serviceAccount:dataflowdemo@${PROJECT}.iam.gserviceaccount.com" \
  --role="roles/dataflow.worker"

并再次运行terraform apply 。 这次我在 terraform 输出中遇到了同样的错误，但在日志中没有看到任何错误。

然后我按照https://cloud.google.com/dataflow/docs/concepts/access-control#creating_jobs给出的建议也授予角色/dataflow.admin：

gcloud projects add-iam-policy-binding $PROJECT \
  --member="serviceAccount:dataflowdemo@${PROJECT}.iam.gserviceaccount.com" \
  --role="roles/dataflow.admin"

但与之前的尝试没有明显区别。

然后我尝试打开提供以下信息的terraform 调试日志记录：

从 dataflow.googleapis.com 返回的错误是显而易见的：

当前用户不能充当服务帐户 serviceAccount:dataflowdemo@redacted.iam.gserviceaccount.com

在这个阶段，我很困惑为什么我可以看到从 Google 的数据流 API 返回错误，但 GCP 日志中没有任何内容表明发生了错误。

然后我灵光一闪。 为什么该错误消息会提到“服务帐户 serviceAccount”？ 然后它击中了我，我错误地定义了服务帐户。 Terraform 代码应该是：

resource "google_dataflow_job" "wordcount" {
  # https://stackoverflow.com/a/59931467/201657
  name              = "wordcount"
  template_gcs_path = "gs://dataflow-templates/latest/Word_Count"
  temp_gcs_location = "gs://${local.name-prefix}-functions/temp"
  parameters = {
    inputFile = "gs://dataflow-samples/shakespeare/kinglear.txt"
    output = "gs://${local.name-prefix}-functions/wordcount/output"
  }
  service_account_email = data.google_service_account.sa.email
}

我更正了它，它立即起作用了。 用户错误！！！

然后我开始删除我添加的各种权限：

gcloud projects remove-iam-policy-binding $PROJECT \
  --member="serviceAccount:dataflowdemo@${PROJECT}.iam.gserviceaccount.com" \
  --role="roles/dataflow.admin"
gcloud projects remove-iam-policy-binding $PROJECT \
  --member="serviceAccount:dataflowdemo@${PROJECT}.iam.gserviceaccount.com" \
  --role="roles/dataflow.worker"

并且terraform apply仍然有效。 但是，在删除角色roles/dataflow.worker的授予后，作业失败并出现错误：

工作流失败。 原因：控制器服务账号权限验证失败。 IAM 角色 roles/dataflow.worker 应授予控制器服务帐户 dataflowdemo@redacted.iam.gserviceaccount.com。

很明显，有关授予适当角色的文档 ( https://cloud.google.com/dataflow/docs/concepts/access-control#creating_jobs ) 是正确的。

显而易见的是，我在知道问题出在哪里之前就开始写这篇文章，并且我认为在某处记录我的调查可能会有用。 现在我已经完成了调查，结果证明问题是PEBCAK之一，它可能与该线程不再那么相关，当然不应该被接受为答案。 尽管如此，这里可能有一些关于如何调查使用 Terraform 调用 Google API 的问题的有用信息，并且它还重申了所需的角色授权，所以我将把它留在这里以防它被证明有用。

Answer 3

我刚刚又遇到了这个问题，所以在这里发布了我的解决方案，因为我完全预料到我会在某个时候再次被这个问题困扰。

我收到错误：

错误：googleapi：错误 403：(a00eba23d59c1fa3)：当前用户不能充当服务帐户 dataflow-controller-sa@myproject.iam.gserviceaccount.com。 原因：（a00eba23d59c15ac）：当前用户不能充当服务帐户 dataflow-controller-sa@myproject.iam.gserviceaccount.com., forbidden

我正在通过 Terraform 使用不同的服务帐户deployer@myproject.iam.gserviceaccount.com部署数据流作业

解决方案是授予该服务帐户roles/iam.serviceAccountUser角色：

gcloud projects add-iam-policy-binding myproject \
    --member=serviceAccount:deployer@myproject.iam.gserviceaccount.com \
    --role=roles/iam.serviceAccountUser

对于那些更喜欢自定义 IAM 角色而不是预定义 IAM 角色的人来说，缺少的特定权限是iam.serviceAccounts.actAs 。

Answer 4

问题已解决！

转到 GCP -> 控制台 -> IAM -> ServiceAccount 电子邮件 -> 添加权限 -> 服务帐户用户。 如下
