このドキュメントでは、Cloud Data Fusion サービス アカウントにリソースへのアクセスできるようにするカスタムロールを作成するときに、Cloud Data Fusion サービス アカウントに付与する権限について説明します。
デフォルトでは、Cloud Data Fusion API サービス エージェント（roles/datafusion.serviceAgent）の Identity and Access Management ロールが Cloud Data Fusion サービス アカウントに割り当てられています。このロールは非常に許容度が高いロールです。代わりに、カスタムロールを使用して、サービス アカウント プリンシパルに必要な権限のみを付与できます。
