为了完成NAS文件系统的某个功能,NAS将自动创建NAS服务关联角色获取访问云服务器ECS、专有网络VPC等云服务的权限。
应用场景
- AliyunServiceRoleForNasStandard
创建通用型NAS文件系统的经典网络类型挂载点时,需要通过AliyunServiceRoleForNasStandard角色访问您的云服务器ECS服务,获取资源列表实现鉴权逻辑。
- AliyunServiceRoleForNasExtreme
极速型NAS文件系统创建挂载点时,需要通过AliyunServiceRoleForNasExtreme角色访问您的专有网络VPC服务与云服务器ECS服务。
- AliyunServiceRoleForNasEncryption
创建用户管理密钥(KMS)加密的文件系统时,需要通过AliyunServiceRoleForNasEncryption角色访问密钥管理服务KMS,获取您托管给密钥管理服务KMS的密钥信息,并为您选择的密钥添加标签,防止您误删除密钥导致文件系统不可用。
- AliyunServiceRoleForNasLogDelivery
使用NAS日志分析功能时,需要通过AliyunServiceRoleForNasLogDelivery角色访问日志服务SLS,并在您的日志服务中创建Project和Logstore,将NAS中存储的日志数据转储至Logstore中。
- AliyunServiceRoleForNasBackup
在创建通用型文件系统时,若要使用文件备份功能,需要通过AliyunServiceRoleForNasBackup角色开通混合云备份服务并创建备份计划。
- AliyunServiceRoleForNasEcsHandler
当您在NAS控制台使用一键挂载功能挂载文件系统时,需要通过AliyunServiceRoleForNasEcsHandler角色访问ECS云助手,并使用ECS云助手为一台或多台ECS实例触发一条云助手命令,实现挂载、卸载文件系统及查询ECS挂载状态。
权限说明

{ "Version": "1", "Statement": [ { "Action": [ "vpc:DescribeVSwitchAttributes", "vpc:DescribeVpcs", "vpc:DescribeVSwitches" ], "Resource": "*", "Effect": "Allow" }, { "Action": [ "ecs:CreateSecurityGroup", "ecs:DescribeSecurityGroups", "ecs:DescribeSecurityGroupAttribute", "ecs:DeleteSecurityGroup", "ecs:AuthorizeSecurityGroup", "ecs:CreateNetworkInterface", "ecs:DeleteNetworkInterface", "ecs:DescribeNetworkInterfaces", "ecs:CreateNetworkInterfacePermission", "ecs:DescribeNetworkInterfacePermissions", "ecs:DeleteNetworkInterfacePermission" ], "Resource": "*", "Effect": "Allow" } ] }
{ "Statement": [ { "Effect": "Allow", "Action": [ "kms:Listkeys", "kms:Listaliases", "kms:ListResourceTags", "kms:DescribeKey", "kms:TagResource", "kms:UntagResource" ], "Resource": "acs:kms:*:*:*" }, { "Effect": "Allow", "Action": [ "kms:Encrypt", "kms:Decrypt", "kms:GenerateDataKey" ], "Resource": "acs:kms:*:*:*/*", "Condition": { "StringEqualsIgnoreCase": { "kms:tag/acs:nas:instance-encryption": "true" } } } ], "Version": "1" }
{ "Version": "1", "Statement": [ { "Action": [ "log:PostLogStoreLogs" ], "Resource": "*", "Effect": "Allow" } ] }
{ "Version": "1", "Statement": [{ "Action": [ "hbr:OpenHbrService", "hbr:CreateTrialBackupPlan" ], "Resource": "*", "Effect": "Allow" }, { "Action": "ram:DeleteServiceLinkedRole", "Resource": "*", "Effect": "Allow", "Condition": { "StringEquals": { "ram:ServiceName": "backup.nas.aliyuncs.com" } } }, { "Action": "ram:CreateServiceLinkedRole", "Resource": "*", "Effect": "Allow", "Condition": { "StringEquals": { "ram:ServiceName": "nasbackup.hbr.aliyuncs.com" } } } ] }
{ "Version": "1", "Statement": [ { "Action": "ram:DeleteServiceLinkedRole", "Resource": "*", "Effect": "Allow", "Condition": { "StringEquals": { "ram:ServiceName": "ecs-handler.nas.aliyuncs.com" } } }, { "Effect": "Allow", "Action": [ "ecs:InvokeCommand" ], "Resource": [ "acs:ecs:*:*:instance/*", "acs:ecs:*:*:command/cmd-ACS-NAS-ClickMount-*" ] }, { "Effect": "Allow", "Action": [ "ecs:DescribeInstances", "ecs:DescribeCloudAssistantStatus" ], "Resource": [ "acs:ecs:*:*:instance/*" ] }, { "Effect": "Allow", "Action": [ "ecs:DescribeInvocations", "ecs:DescribeInvocationResults" ], "Resource": [ "*" ] } ] }
删除NAS服务关联角色
如果您暂时不需要使用NAS服务关联角色,例如不需要创建用户管理密钥(KMS)加密的文件系统时,可以删除NAS服务关联角色。删除时,请先删除该角色关联的文件系统实例。具体操作,请参见删除文件系统和删除服务关联角色。
常见问题
为什么我的RAM用户无法自动创建NAS服务关联角色?
只有拥有指定权限的用户,才能自动创建或删除文件存储NAS服务关联角色。当RAM用户无法自动创建文件存储NAS服务关联角色时,需要为RAM用户添加以下权限策略。使用时请将主账号ID
替换为实际的阿里云账号(主账号)ID。具体操作,请参见为RAM角色授权。
{
"Statement": [
{
"Action": [
"ram:CreateServiceLinkedRole"
],
"Resource": "acs:ram:*:主账号ID:role/*",
"Effect": "Allow",
"Condition": {
"StringEquals": {
"ram:ServiceName": [
"standard.nas.aliyuncs.com",
"extreme.nas.aliyuncs.com",
"encryption.nas.aliyuncs.com",
"logdelivery.nas.aliyuncs.com",
"ecs-handler.nas.aliyuncs.com"
