amazon-web-services - 附加 AmazonS3FullAccess 时 AWS Glue 爬网程序访问被拒绝

Question

我刚刚设置了一个 AWS Glue 爬网程序来爬网 S3 存储桶。我已为爬网程序设置了 IAM 角色，并将托管策略“AWSGlueServiceRole”和“AmazonS3FullAccess”附加到该角色。我已确保爬网程序正在使用该角色。但是，每次运行爬网程序时，我都会在日志中收到类似以下内容的错误消息:

ERROR : Error Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: <omitted>; S3 Extended Request ID: <omitted>) retrieving file at s3://my-bucket/snapshots/snapshot-1/mydb/mydb.mytable/11/part-00000-ffffffff-ffff-ffff-ffff-ffffffffffff-c000.gz.parquet. Tables created did not infer schemas from this file.

我已确认执行角色附加了“AmazonS3ReadOnlyAccess”的 Lambda 能够访问该存储桶。我做错了什么？

编辑:设置“阻止所有公共(public)访问”或禁用它没有明显的效果。

EDIT2:IAM 角色的托管策略文档如下。没有内联策略。

Answer 1

事实证明问题出在 KMS 上。该存储桶包含 Aurora RDS 快照的导出，并且该快照显然是加密写入的。因此，一旦添加了以下策略，我就确定了:

{
  "Version": "2012-10-17",
  "Statement": {
    "Effect": "Allow",
    "Action": [
      "kms:Decrypt"
    ],
    "Resource": [
      "arn:aws:kms:<region>:<my account id>:key/<my key id>"
    ]
  }
}

这是附加到该角色的整个托管策略(请注意，该角色还附加了 AWSGlueServiceRole):

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::my-bucket/snapshots*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "kms:Decrypt"
            ],
            "Resource": [
                "arn:aws:kms:<region>:<my account id>:key/<my key id>"
            ]
        }
    ]
}
