使用 Codebuild 将 DynamoDB 导出到 S3 到另一个帐户

Question

我已经为运行以下命令创建了代码构建。

      aws dynamodb export-table-to-point-in-time \
        --table-arn arn:aws:dynamodb:REDACTED:REDACTED:table/REDACTED \
        --s3-bucket REDACTED \
        --s3-bucket-owner REDACTED

我还创建了一个 service-role 并附加了以下内联策略。

        {
            "Sid": "",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::REDACTED/*",
                "arn:aws:s3:::REDACTED"
            ]
        }

最后，我更新了 S3 存储桶以允许 service-role 写入存储桶：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::REDACTED:role/service-role/REDACTED"
            },
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::REDACTED/*",
                "arn:aws:s3:::REDACTED"
            ]
        }
    ]
}

代码构建正确调用命令，但由于权限原因导出失败。

    }
}

如果我从 AWS 控制台调用（即作为我的用户），我可以导出跨账户。但是使用代码构建和上面的命令，它失败了。

我错过了什么？

我解决了这个问题。

问题是在 aws dynamodb export-table-to-point-in-time CLI 命令中引用了错误的 accountId。
