When a bucket is created via an S3 API request, a view is created for the bucket. That view is manageable via VMS.
Views that are created this way are configured based on an S3 Endpoint-enabled view. S3 Endpoint can be selected as a protocol when creating a view. An S3 Endpoint view acts as a template for creating a view on a bucket. The S3 Endpoint view provides the view policy and the Element Store path under which the bucket is created.
You can create multiple S3 Endpoint views and use them to manage the path placement of new buckets in the Element Store.
S3 Endpoint views specify bucket creator users and groups. When a user creates a bucket by S3 API request, the view is created using an S3 Endpoint view that specifies the user as a bucket creator or specifies a group to which the user belongs as a bucket creator group.
If the requesting user is not specified in any S3 Endpoint view as a bucket creator, the bucket is placed directly under the root path, '/' of the Element Store and configured with a default view policy called S3_default_policy.
There is a cluster setting that enables you to restrict bucket creation via S3 API requests to S3 Endpoint views. The setting is called S3 Force Endpoint Bucket Creation. If you enable this setting, requests to create buckets fail if the user is not specified as a bucket owner for an S3 Endpoint-view.
It is possible to enable NFSv3 and NFSv4.1 protocols on the same view as S3 Endpoint protocol. The NFS protocols are then able to access the Element Store path into which the buckets are placed.
To create an S3 Endpoint view, follow the VAST Web UI or VAST CLI procedure in Creating Views to create a view and choose the following configurations:
Enable S3 Endpoint as a protocol.
Specify users and/or groups as bucket creators.
Specify a view policy that has S3 Native flavor.
Go to the Cluster settings page (either search for "Cluster" or select Settings from the menu and then Cluster).
Slide the S3 Force Endpoint Bucket Creation slider to the ON position to disallow bucket creation outside of S3 endpoints or to the OFF position to allow bucket creation API requests without the user being a specified bucket owner in an S3 Endpoint view.
You can create a bucket via VMS by creating a view and enabling S3 Bucket as a protocol. When creating a bucket this way, you specify a user as a bucket owner.
To create an S3 Bucket view, follow the VAST Web UI or VAST CLI procedure in Creating Views to create a view and choose the following configurations:
Select S3 Bucket as a protocol.
Set the name of the bucket if you wish. Otherwise the view's path with default as the bucket name.
Choose a view policy with a security flavor that supports S3 (either NFS or S3 Native).
Set the bucket owner to the user name of a user that has an entry on a provider such as Active Directory or the local provider.
Optionally, enable S3 features.
