3.11. 删除旧的 overcloud 镜像

流程

1. 检查您不再使用的镜像：

   $ openstack image list
   
   +--------------------------------------+-----------------------------------------+--------+
   | ID                                   | Name                                    | Status |
   +--------------------------------------+-----------------------------------------+--------+

   | 1d5b38d1-4a84-48a1-b830-d45643f11a2b | bm-deploy-ramdisk_20200922T105131Z      | active |
   | b87a6265-cf2a-4dfa-9020-c5293300615d | overcloud-full                          | active |

2. 删除每个旧镜像：

   以下示例删除所有在其名称中带有时间戳的镜像，如 20200922T105130Z 或 20220822T092159Z ：

   $ source ~/stackrc
   $ openstack image list -c Name -f value | egrep "_202[0-9]+T[0-9]+Z" | xargs openstack image delete

   Copy to Clipboard Toggle word wrap
   注意

   如果您将您的环境从 RHOSP 13.0 升级到 16.2，则镜像不包含时间戳。以下示例演示了如何在名称中删除带有 bm-deploy 的镜像，它们不再需要：

   $ openstack image list -c Name -f value | egrep bm-deploy | xargs openstack image delete
