3.1.1. Using the Command-line
Copier lien

You can use Identity Service (keystone) groups to assign consistent permissions to multiple user accounts. This example creates a group and then assigns permissions to the group. As a result, members of the group will inherit the same permissions that were assigned to the group:

Note

The openstack group subcommands require keystone v3.

  1. Create the group grp-Auditors: 

    $ openstack group create grp-Auditors
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description |                                  |
| domain_id   | default                          |
| id          | 2a4856fc242142a4aa7c02d28edfdfff |
| name        | grp-Auditors                     |
+-------------+----------------------------------+

  2. View a list of keystone groups: 

    $ openstack group list --long
+----------------------------------+--------------+-----------+-------------+
| ID                               | Name         | Domain ID | Description |
+----------------------------------+--------------+-----------+-------------+
| 2a4856fc242142a4aa7c02d28edfdfff | grp-Auditors | default   |             |
+----------------------------------+--------------+-----------+-------------+

  3. Grant the grp-Auditors group permission to access the demo project, while using the _member_ role: 

    $ openstack role add _member_ --group grp-Auditors --project demo

  4. Add the existing user user1 to the grp-Auditors group: 

    $ openstack group add user grp-Auditors user1
user1 added to group grp-Auditors

  5. Confirm that user1 is a member of grp-Auditors: 

    $ openstack group contains user grp-Auditors user1
user1 in group grp-Auditors

  6. Review the effective permissions that have been assigned to user1: 

    $ openstack role assignment list --effective --user user1
+----------------------------------+----------------------------------+-------+----------------------------------+--------+-----------+
| Role                             | User                             | Group | Project                          | Domain | Inherited |
+----------------------------------+----------------------------------+-------+----------------------------------+--------+-----------+
| 9fe2ff9ee4384b1894a90878d3e92bab | 3fefe5b4f6c948e6959d1feaef4822f2 |       | 0ce36252e2fb4ea8983bed2a568fa832 |        | False     |
+----------------------------------+----------------------------------+-------+----------------------------------+--------+-----------+
