12.2. 创建 RBAC 策略

本例流程演示了如何使用基于角色的访问控制(RBAC)策略来授予项目对共享网络的访问权限。

  1. 查看可用网络列表： 

    # openstack network list
+--------------------------------------+-------------+-------------------------------------------------------+
| id                                   | name        | subnets                                               |
+--------------------------------------+-------------+-------------------------------------------------------+
| fa9bb72f-b81a-4572-9c7f-7237e5fcabd3 | web-servers | 20512ffe-ad56-4bb4-b064-2cb18fecc923 192.168.200.0/24 |
| bcc16b34-e33e-445b-9fde-dd491817a48a | private     | 7fe4a05a-4b81-4a59-8c47-82c965b0e050 10.0.0.0/24      |
| 9b2f4feb-fee8-43da-bb99-032e4aaf3f85 | public      | 2318dc3b-cff0-43fc-9489-7d4cf48aaab9 172.24.4.224/28  |
+--------------------------------------+-------------+-------------------------------------------------------+

  2. 查看项目列表： 

    # openstack project list
+----------------------------------+----------+
| ID                               | Name     |
+----------------------------------+----------+
| 4b0b98f8c6c040f38ba4f7146e8680f5 | auditors |
| 519e6344f82e4c079c8e2eabb690023b | services |
| 80bf5732752a41128e612fe615c886c6 | demo     |
| 98a2f53c20ce4d50a40dac4a38016c69 | admin    |
+----------------------------------+----------+

  3. 为 web-servers 网络创建一个 RBAC 条目，它授予对 auditors 项目的访问权限(4b0b98f8c6c040f38ba4f7146e8680f5)： 

    # openstack network rbac create --type network --target-project 4b0b98f8c6c040f38ba4f7146e8680f5 --action access_as_shared web-servers
Created a new rbac_policy:
+----------------+--------------------------------------+
| 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     |
+----------------+--------------------------------------+

因此，审核员 项目中的用户可以将实例连接到 web-servers 网络。
