Amazon RedShift：访问被拒绝RestoreClusterSnapshot请求 [英] Amazon Redshift : Acces Denied RestoreClusterSnapshotRequest

问题描述

尝试使用快照恢复群集时遇到问题。如有任何指点，我将不胜感激。

使用的代码为：

var con = new AmazonRedshiftClient(acess_key_id, secret_acess_key, Amazon.RegionEndpoint.USWest2);

        var restore = new Amazon.Redshift.Model.RestoreFromClusterSnapshotRequest()
        {
            ClusterIdentifier = clusterIdentifier,
            SnapshotIdentifier = snapshotIdentifier,
            AvailabilityZone = "us-west-2a",
        };

        var response = con.RestoreFromClusterSnapshot(restore);

        Console.WriteLine("Cluster Status : {0}", response.Cluster.ClusterStatus);

当它调用RestoreClusterSnapshotRequest操作时，我有一个异常： "访问被拒绝。请确保您的IAM权限允许此操作。"

对Amazon RedShift使用基于身份的策略(IAM策略)如下 政策：

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "redshift:CopyClusterSnapshot",
            "redshift:RestoreFromClusterSnapshot",
            "redshift:AuthorizeSnapshotAccess",
            "redshift:RevokeSnapshotAccess"
        ],
        "Resource": [
            "arn:aws:redshift:us-west-2:{AccoundId}:*/backup-20160208-dbrd",
            "arn:aws:redshift:us-west-2: {AccoundId}:cluster:*"
        ]
    },
    {
        "Effect": "Allow",
        "Action": [
            "redshift:DescribeClusterSnapshots"
        ],
        "Resource": [
            "*"
        ]
    }
]

}

谁能帮我克服这个问题？如果我在这个过程中有任何错误，请纠正我。。

提前谢谢

推荐答案

按照the other answer中的建议，您应该更改此行：

"arn:aws:redshift:us-west-2:{AccoundId}:*/backup-20160208-dbrd",

至

"arn:aws:redshift:us-west-2:{AccoundId}:snapshot:*/backup-20160208-dbrd",

此外，通过大量试验和AWS支持人员的帮助，我发现您还需要几个ec2权限才能从快照恢复RedShift集群。此时的列表为：

    {
        "Sid": "",
        "Effect": "Allow",
        "Action": [
            "ec2:DescribeAccountAttributes",
            "ec2:DescribeAddresses",
            "ec2:DescribeAvailabilityZones",
            "ec2:DescribeSecurityGroups",
            "ec2:DescribeSubnets",
            "ec2:DescribeVpcs",
            "ec2:DescribeInternetGateways"
        ],
        "Resource": "*"
    }

您可能只想执行ec2:Describe*以方便和/或防止将来更改确切的权限集时中断此操作。

应很快使用此信息更新Amazon Redshift Snapshots docs(搜索"RestoreFromClusterSnapshot")。
