Using tags with Amazon FSx
You can use tags to control access to Amazon FSx resources and to implement attribute-based access control (ABAC). To apply tags to Amazon FSx resources during creation, users must have certain AWS Identity and Access Management (IAM) permissions.
Grant permission to tag resources during creation
With some resource-creating Amazon FSx API actions, you can specify tags when you create the resource. You can use these resource tags to implement attribute-based access control (ABAC). For more information, see What is ABAC for AWS? in the IAM User Guide.
For users to tag resources on creation, they must have permission to use the action that
creates the resource, such as fsx:CreateFileSystem
,
fsx:CreateStorageVirtualMachine
, or fsx:CreateVolume
. If tags are
specified in the resource-creating action, IAM performs additional authorization on the
fsx:TagResource
action to verify if users have permissions to create tags.
Therefore, users must also have explicit permissions to use the fsx:TagResource
action.
The following example policy allows users to create file systems and storage virtual machines (SVMs) and apply tags to them during creation in a specific AWS account.
{ "Statement": [ { "Effect": "Allow", "Action": [ "fsx:CreateFileSystem", "fsx:CreateStorageVirtualMachine", "fsx:TagResource" ], "Resource": [ "arn:aws:fsx:
region
:account-id
:file-system/*", "arn:aws:fsx:region
:account-id
:file-system/*/storage-virtual-machine
/*" ] } ] }
Similarly, the following policy allows users to create backups on a specific file system and apply any tags to the backup during backup creation.
{ "Statement": [ { "Effect": "Allow", "Action": [ "fsx:CreateBackup" ], "Resource": "arn:aws:fsx:
region
:account-id
:file-system/file-system-id
*" }, { "Effect": "Allow", "Action": [ "fsx:TagResource" ], "Resource": "arn:aws:fsx:region
:account-id
:backup/*" } ] }
The fsx:TagResource
action is evaluated only if tags are applied during the
resource-creating action. Therefore, a user who has permissions to create a resource (assuming
there are no tagging conditions) does not require permission to use the
fsx:TagResource
action if no tags are specified in the request. However, if the
user attempts to create a resource with tags, the request fails if the user does not have
permissions to use the fsx:TagResource
action.

Using tags to control access to your Amazon FSx resources
To control access to Amazon FSx resources and actions, you can use IAM policies based on tags. You can provide this control in two ways:
-
You can control access to Amazon FSx resources based on the tags on those resources.
-
You can control which tags can be passed in an IAM request condition.
For information about how to use tags to control access to AWS resources, see Controlling access using tags in the IAM User Guide. For more information about tagging Amazon FSx resources at creation, see Grant permission to tag resources during creation. For more information about tagging resources, see Tagging Amazon FSx resources.
Controlling access based on tags on a resource
To control which actions a user or role can perform on an Amazon FSx resource, you can use tags on the resource. For example, you might want to allow or deny specific API operations on a file system resource based on the key-value pair of the tag on the resource.
Example policy – Create a file system only when a specific tag is used
This policy allows the user to create a file system only when they tag it with a
specific tag key-value pair, in this example, key=Department
,
value=Finance
.
{ "Effect": "Allow", "Action": [ "fsx:CreateFileSystem", "fsx:TagResource" ], "Resource": "arn:aws:fsx:
region
:account-id
:file-system/*", "Condition": { "StringEquals": { "aws:RequestTag/Department": "Finance" } } }
Example policy – Create backups only of Amazon FSx for NetApp ONTAP volumes with a specific tag
This policy allows users to create backups only of FSx for ONTAP volumes that are tagged
with the key-value pair key=Department
, value=Finance
. The
backup is created with the tag Department=Finance
.
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "fsx:CreateBackup" ], "Resource": "arn:aws:fsx:
region
:account-id
:volume/*", "Condition": { "StringEquals": { "aws:ResourceTag/Department": "Finance" } } }, { "Effect": "Allow", "Action": [ "fsx:TagResource", "fsx:CreateBackup" ], "Resource": "arn:aws:fsx:region
:account-id
:backup/*", "Condition": { "StringEquals": { "aws:RequestTag/Department": "Finance" } } } ] }
Example policy – Create a volume with a specific tag from backups with a specific tag
This policy allows users to create volumes that are tagged with Department=Finance
only
from backups that are tagged with Department=Finance
.
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "fsx:CreateVolumeFromBackup", "fsx:TagResource" ], "Resource": "arn:aws:fsx:
region
:account-id
:volume/*", "Condition": { "StringEquals": { "aws:RequestTag/Department": "Finance" } } }, { "Effect": "Allow", "Action": [ "fsx:CreateVolumeFromBackup" ], "Resource": "arn:aws:fsx:region
:account-id
:backup/*", "Condition": { "StringEquals": { "aws:ResourceTag/Department": "Finance" } } } ] }
Example policy – Delete file systems with specific tags
This policy allows a user to delete only file systems that are tagged with Department=Finance
.
If they create a final backup, then it must be tagged with Department=Finance
.
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "fsx:DeleteFileSystem" ], "Resource": "arn:aws:fsx:
region
:account-id
:file-system/*", "Condition": { "StringEquals": { "aws:ResourceTag/Department": "Finance" } } }, { "Effect": "Allow", "Action": [ "fsx:TagResource" ], "Resource": "arn:aws:fsx:region
:account-id
:backup/*", "Condition": { "StringEquals": { "aws:RequestTag/Department": "Finance" } } } ] }
