【データ基盤】GCPのdataprocの技術を使用した所管どころ

Last updated at Posted at 2025-07-23

GCPでもETLツールとしてDataprocが存在する。AWSのGlueやAzureのADFのようにクラウドのETLツールである。

パーミッションのエラーがえぐい

Permissions are missing for the default service account '984478690832-compute@developer.gserviceaccount.com', missing permissions: [storage.buckets.get, storage.objects.create, storage.objects.delete, storage.objects.get, storage.objects.list, storage.objects.update] on the project 'projects/gihyo-306807'. This usually happens when a custom resource (ex: custom staging bucket) or a user-managed VM Service account has been provided and the default/user-managed service account hasn't been granted enough permissions on the resource. See https://cloud.google.com/dataproc/docs/concepts/configuring-clusters/service-accounts#VM_service_account.

リクエスト ID: 8335348273477453190

bash.sh
 gcloud projects add-iam-policy-binding gihyo-306807 \
  --member="serviceAccount:984478690832-compute@developer.gserviceaccount.com" \
  --role="roles/storage.admin"

✅ これはどういう状態か？
Dataproc クラスター作成時に、GCP は通常 自動で一時的な Cloud Storage バケット（staging/temp） を作成します：

❗ 最も重要な推測：
Dataproc が staging/temp バケットを作成しようとしたが、サービスアカウントにその「作成権限」がなかった

missing permissions: [storage.buckets.get, storage.objects.create, ...]
✅ 今すぐやるべき対応
🔹 対応①：プロジェクトに明示的に Cloud Storage 権限を与える
プロジェクト gihyo-306807 にて、サービスアカウントに以下のロールを追加：

gcloud projects add-iam-policy-binding gihyo-306807
--member="serviceAccount:984478690832-compute@developer.gserviceaccount.com"
--role="roles/storage.admin"
これで：

バケットの作成（staging/temp）オブジェクトのアップロード/ダウンロードなど、すべての必要な権限が付与されます。

生成AIのGPTに聞いて、Dataprocが一時的にGCSにバケットを作成する際に権限がなかったのが原因だったようだ。

何とかクラスターが起動した

VMインスタンスを確認すると確かにインスタンスができている

作成したDataprocのクラスター上にジョブを作成してみる。
image.png

ジョブを実行して「完了」になったことがわかる

さて、クラスターの削除しておく

VMインスタンスも削除されたことがわかる

#GCSやNFSの作成

GCSは簡単に作れる。AWSのS3のバケットを作成する感覚でオブジェクトストレージを作成可能である。

NFSであるFireStoreを作成中。(1ヶ月100ドル近いので必ずシャットダウンをしよう)

作成したNFSの設定画面を開くと、マウントする際のファイルシステムが表示される。
