AWS 讀/寫 RDS 策略

abc-database-backups/rds/postgresql-backup在我的場景中，我想要一個允許在 S3 上讀寫的策略？我們希望我的伺服器添加該存取權限。

創建角色並將其附加到伺服器是最好還是向伺服器添加密鑰最好？

我試過這個：

aws iam create-policy \
     --policy-name rds-s3-integration-policy \
     --policy-document '{
            "Version": "2012-10-17",
            "Statement": [
                {
                    "Effect": "Allow",
                    "Action": "s3:ListAllMyBuckets",
                    "Resource": "*"
                },
                {
                    "Effect": "Allow",
                    "Action": [
                        "s3:ListBucket",
                        "s3:GetBucketACL",
                        "s3:GetBucketLocation"
                    ],
                    "Resource": "arn:aws:s3:::bucket_name"
                },
                {
                    "Effect": "Allow",
                    "Action": [
                        "s3:GetObject",
                        "s3:PutObject",
                        "s3:ListMultipartUploadParts",
                        "s3:AbortMultipartUpload"
                    ],
                    "Resource": "arn:aws:s3:::bucket_name/key_prefix/*"
                }
            ]
        }'

我將非常感謝任何幫助，因為我在這一領域的經驗有些有限。

用一個服務相關角色讓 RDS 提供對 S3 和您需要的任何其他命名資源的存取。確保 RDS 實例具有此角色。你也應該閱讀這個文檔關於使用擴充將 S3 資料導入 RDS PostgreSQL。

我已經將一些 CloudFormation 基礎架構改編為我擁有的應該設定角色的程式碼。您需要修改權限和儲存桶名稱以滿足您的要求。它應該按原樣工作，但我確實必須修改我現有的程式碼，所以如果它不能 100% 工作，請編輯帖子或評論，以便我可以編輯它。
