OpsCenter备份到S3用户的IAM策略

Question

使用OpsCenter 5.1.0并尝试将S3添加为快照备份的位置。 AWS IAM对opscenter用户有哪些必要的权限？到目前为止，我有以下政策：

"Statement": [ { "Effect": "Allow", "Action": [ "s3:ListAllMyBuckets", "s3:GetBucketLocation" ], "Resource": "arn:aws:s3:::*" }, { "Effect": "Allow", "Action": [ "s3:ListBucket", "s3:GetBucketLocation" ], "Resource": [ "arn:aws:s3:::cassandra-bkup" ] }, { "Effect": "Allow", "Action": [ "s3:DeleteObject", "s3:GetObject", "s3:PutObject" ], "Resource": [ "arn:aws:s3:::cassandra-bkup/*" ] } ]

但备份仍然失败。在opscenterd.log中，可以看到以下错误：

WARN: Marking request af93899e-ae89-4ada-8b3b-ef93d0272d61 as failed: {'sstables': {'reporting_test': {u'cards': {'total_size': 9829, 'total_files': 6, 'done_files': 0, 'errors': [u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}']},等等。

然而，备份到本地服务器成功。

Answer 1

经过一些反复试验，我发现以下政策有效

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:ListAllMyBuckets", "s3:GetBucketLocation" ], "Resource": "arn:aws:s3:::*" }, { "Effect": "Allow", "Action": [ "s3:ListBucket", "s3:GetBucketLocation", "s3:GetBucketAcl" ], "Resource": [ "arn:aws:s3:::prod-bkup" ] }, { "Effect": "Allow", "Action": [ "s3:DeleteObject", "s3:GetObject", "s3:PutObject" ], "Resource": [ "arn:aws:s3:::prod-bkup/*" ] } ] }

编辑：添加s3:GetBucketAcl作为必需的权限
