Create RBAC policies

Grant a project access to a shared network by creating a role-based access control (RBAC) policy.

Before you begin

  • The administrator has created a project for you and has provided you with a clouds.yaml file for you to access the cloud.
  • The python-openstackclient package is on your workstation. 
    $ dnf list installed python-openstackclient

Procedure

  1. Confirm that the system OS_CLOUD variable is set for your cloud: 
    $ echo $OS_CLOUD
my_cloud

    Reset the variable if necessary:

    $ export OS_CLOUD=my_other_cloud

    As an alternative, you can specify the cloud name by adding the --os-cloud <cloud_name> option each time you run an openstack command.

  2. View the list of available networks: 
    $ openstack network list

  4. Create a RBAC entry for the web-servers network that grants access to the auditors project (4b0b98f8c6c040f38ba4f7146e8680f5): 
    $ openstack network rbac create --type network --target-project 4b0b98f8c6c040f38ba4f7146e8680f5 --action access_as_shared web-servers
    Sample output
    +----------------+--------------------------------------+
| Field          | Value                                |
+----------------+--------------------------------------+
| action         | access_as_shared                     |
| id             | 314004d0-2261-4d5e-bda7-0181fcf40709 |
| object_id      | fa9bb72f-b81a-4572-9c7f-7237e5fcabd3 |
| object_type    | network                              |
| target_project | 4b0b98f8c6c040f38ba4f7146e8680f5     |
| project_id     | 98a2f53c20ce4d50a40dac4a38016c69     |
+----------------+--------------------------------------+

    As a result, users in the auditors project can connect instances to the web-servers network.
