aws rds copy-db-snapshotKMS 暗号化キーを使用するための最小限のアクセス許可を設定しようとしています。
$ aws rds copy-db-snapshot --source-db-snapshot-identifier rds-backup-share-
mysql --target-db-snapshot-identifier rds-backup-share-mysql-reencrypted --kms-key-id <kms-arn>
(内部のすべて<>が私によって取り除かれ、有効な値が含まれています。)
残念ながら、次のエラーが表示されます。
An error occurred (KMSKeyNotAccessibleFault) when calling the CopyDBSnapshot operation: The target snapshot KMS key [<kms-arn>] does not exist, is not enabled or you do not have permissions to access it.
現在、次のアクションを許可しています。
"Action": [
"kms:ReEncrypt*",
"kms:ListKeys",
"kms:ListAliases",
"kms:GenerateDataKey*",
"kms:Encrypt",
"kms:DescribeKey",
"kms:Decrypt"
],
に置き換えると機能するkms:*{code}ので、パーミッションの問題に違いありません。
CloudTrail で正しいアクセス許可を見つけようとしましたが、同じ役に立たないエラー メッセージが含まれているだけです。
だから私の実際の質問：
- CopyDBSnapshot の最小 KMS アクセス許可は何ですか?
- 必要なアクセス許可を把握する一般的な方法はありますか? 必要なアクセス許可をグーグル検索して時間を無駄にするのは、いつも苦痛です。
