6.5.5. 验证镜像服务的采用

流程

1. 通过 Red Hat OpenStack Platform CLI 测试镜像服务。您可以比较并确保配置应用到镜像服务 pod:

   $ os-diff diff /etc/glance/glance.conf.d/02-config.conf glance_patch.yaml --frompod -p glance-api

   如果没有显示行，则配置正确。

2. 检查生成的镜像服务 pod：

   GLANCE_POD=`oc get pod |grep glance-default | cut -f 1 -d' ' | head -n 1`
   oc exec -t $GLANCE_POD -c glance-api -- cat /etc/glance/glance.conf.d/02-config.conf
   
   [DEFAULT]
   enabled_backends=default_backend:rbd
   [glance_store]
   default_backend=default_backend
   [default_backend]
   rbd_store_ceph_conf=/etc/ceph/ceph.conf
   rbd_store_user=openstack
   rbd_store_pool=images
   store_description=Ceph glance store backend.

3. 如果使用 Red Hat Ceph Storage 后端，请确保挂载 Red Hat Ceph Storage secret：

   $ oc exec -t $GLANCE_POD -c glance-api -- ls /etc/ceph
   ceph.client.openstack.keyring
   ceph.conf

4. 检查服务是否活跃，并在 RHOSP CLI 中更新端点：

   $ oc rsh openstackclient
   $ openstack service list | grep image
   
   | fc52dbffef36434d906eeb99adfc6186 | glance    | image        |
   
   $ openstack endpoint list | grep image
   
   | 569ed81064f84d4a91e0d2d807e4c1f1 | regionOne | glance       | image        | True    | internal  | http://glance-internal-openstack.apps-crc.testing   |
   | 5843fae70cba4e73b29d4aff3e8b616c | regionOne | glance       | image        | True    | public    | http://glance-public-openstack.apps-crc.testing     |

5. 检查您之前在源云中列出的镜像是否在采用的服务中可用：

   $ openstack image list
