AWS::S3::AccessGrant

The AWS::S3::AccessGrant resource creates an access grant that gives a grantee access to your S3 data. The grantee can be an IAM user or role or a directory user, or group. Before you can create a grant, you must have an S3 Access Grants instance in the same Region as the S3 data. You can create an S3 Access Grants instance using the AWS::S3::AccessGrantsInstance. You must also have registered at least one S3 data location in your S3 Access Grants instance using AWS::S3::AccessGrantsLocation.

Permissions

You must have the s3:CreateAccessGrant permission to use this resource.

Additional Permissions

For any directory identity - sso:DescribeInstance and sso:DescribeApplication

For directory users - identitystore:DescribeUser

For directory groups - identitystore:DescribeGroup

    }
}

Properties

AccessGrantsLocationConfiguration

The configuration options of the grant location. The grant location is the S3 path to the data to which you are granting access. It contains the S3SubPrefix field. The grant scope is the result of appending the subprefix to the location scope of the registered location.

Required: No

Type: AccessGrantsLocationConfiguration

Update requires: No interruption

AccessGrantsLocationId

Required: Yes

Type: String

Allowed values: READ | WRITE | READWRITE

Update requires: No interruption

S3PrefixType
