Creating Groups with Single and Multiple Prefixes

Some examples of single-prefix and multiple-prefix groups

The RBAC group definitions support cases where multiple prefixes can be used for various conditions. When a group requires its users to access multiple prefixes, the RBAC permission definitions can be updated to refer to multiple bucket names or prefixes. Refer to the following examples.

🚧

NOTE:

While it is possible to specify multiple prefixes and/or buckets, use caution before configuring too many prefixes or buckets. In a practical sense, granting more than 5-10 prefixes or buckets could be difficult to maintain and manage.
