我有一种情况，我需要限制 s3 存储桶以拒绝除提供的 ips 列表之外的所有其他 ips，但也允许访问雪花。由于雪花在一个区域中使用的可能 IP 地址列表很多 - https://ip-ranges.amazonaws.com/ip-ranges.json，我试图查看是否可以提供基于为雪花 s3 阶段创建的雪花角色。我尝试的策略如下所示。

{
    "Version": "2012-10-17",
    "Id": "SourceIP",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::11111111111:role/snowflake-role"
            },
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::s3-bucket"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::111111111111:role/snowflake-role"
            },
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": "arn:aws:s3:::s3-bucket/*"
        },
        {
            "Sid": "SourceIP",
            "Effect": "Deny",
            "Principal": "*",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::s3-bucket",
                "arn:aws:s3:::s3-bucket/*"
            ],
            "Condition": {
                "NotIpAddress": {
                    "aws:SourceIp": [
                        "10.10.100.10",
                        "10.10.100.11",
                        "10.10.100.12",
                        "10.10.100.13"
                    ]
                }
            }
        }
    ]
}

这非常适合阻止其他 IP 地址，但 Snowflake 无法访问。由于“拒绝”可能会拒绝所有 IP 地址，而不管上述雪花的“允许”声明如何，我尝试了如下允许 IP 地址。

{
    "Version": "2012-10-17",
    "Id": "SourceIP",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::11111111111:role/snowflake-role"
            },
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::s3-bucket"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::111111111111:role/snowflake-role"
            },
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": "arn:aws:s3:::s3-bucket/*"
        },
        {
            "Sid": "SourceIP",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::s3-bucket",
                "arn:aws:s3:::s3-bucket/*"
            ],
            "Condition": {
                "IpAddress": {
                    "aws:SourceIp": [
                        "10.10.100.10",
                        "10.10.100.11",
                        "10.10.100.12",
                        "10.10.100.13"
                    ]
                }
            }
        }
    ]
}

现在雪花可以访问但ip限制不起作用。所有 ip 都可以访问存储桶。有人可以帮我解决我的情况吗？

我认为确实最优雅的解决方案是创建一个 IAM 角色并将其分配给您希望允许访问 S3 存储桶的相应雪花。Deny之后，使用明确的 for阻止对存储桶的所有访问"Principal" : "*"。最后，您可以使用aws:userId或aws:PrincipalArn条件键仅允许具有该角色的用户访问存储桶。
