openstack nova租户配额

查看默认配额

默认配额

[root@controller ~]# nova quota-defaults
+----------------------+-------+
| Quota                | Limit |
+----------------------+-------+
| instances            | 10    |
| cores                | 20    |
| ram                  | 51200 |
| metadata_items       | 128   |
| key_pairs            | 100   |
| server_groups        | 10    |
| server_group_members | 10    |
+----------------------+-------+

修改默认配额:例如

nova quota-class-update default --instances 15

例如:

  • 查看项目的 id:
[root@controller ~]# openstack project show -f value -c id service
4454e6deae3640b190d5ad2c3571e90d

或者

[root@controller ~]# openstack project list | awk '/service/ {print $2}'
4454e6deae3640b190d5ad2c3571e90d
  • 获取项目配额:
[root@controller ~]# tenant=$(openstack project list | awk '/service/ {print $2}')
[root@controller ~]# nova quota-show --tenant $tenant
+----------------------+-------+
| Quota                | Limit |
+----------------------+-------+
| instances            | 10    |
| cores                | 20    |
| ram                  | 51200 |
| metadata_items       | 128   |
| key_pairs            | 100   |
| server_groups        | 10    |
| server_group_members | 10    |
+----------------------+-------+

更新项目的配额值:例如

nova quota-update --user $projectUser --floating-ips 12 $project
  • 查看当前配额使用情况
[root@controller ~]# nova limits --tenant $tenant  
+------+-----+-------+--------+------+----------------+  
| Verb | URI | Value | Remain | Unit | Next_Available |  
+------+-----+-------+--------+------+----------------+  
+------+-----+-------+--------+------+----------------+  
+--------------------+------+-------+  
| Name               | Used | Max   |  
+--------------------+------+-------+  
| Cores              | 0    | 20    |  
| Instances          | 0    | 10    |  
| Keypairs           | -    | 100   |  
| RAM                | 0    | 51200 |  
| Server Meta        | -    | 128   |  
| ServerGroupMembers | -    | 10    |  
| ServerGroups       | 0    | 10    |

| snapshots            | 10    |
| volumes              | 10    |

修改之后:

[root@controller ~]# cinder quota-update --volumes 15 4454e6deae3640b190d5ad2c3571e90d
