4.3. 配置 Red Hat Ceph Storage 后端

流程

1. 创建包含 Red Hat Ceph Storage 配置的 ceph-conf-files secret：

   $ oc apply -f - <<EOF
   apiVersion: v1
   data:
     ceph.client.openstack.keyring: $CEPH_KEY
     ceph.conf: $CEPH_CONF
   kind: Secret
   metadata:
     name: ceph-conf-files
   type: Opaque
   EOF

   文件的内容应类似以下示例：

   apiVersion: v1
   kind: Secret
   metadata:
     name: ceph-conf-files
   stringData:
     ceph.client.openstack.keyring: |
       [client.openstack]
           key = <secret key>
           caps mgr = "allow *"
           caps mon = "allow r, profile rbd"
           caps osd = "pool=vms, profile rbd pool=volumes, profile rbd pool=images, allow rw pool manila_data'
     ceph.conf: |
       [global]
       fsid = 7a1719e8-9c59-49e2-ae2b-d7eb08c695d4
       mon_host = 10.1.1.2,10.1.1.3,10.1.1.4 

   1

   1

   如果您使用 IPv6，请将括号用于 mon_host。例如： mon_host = [v2:[fd00:cc::100]:3300/0,v1:[fd00:cccc::100]:6789/0]

2. 在 OpenStackControlPlane CR 中，将 ceph.conf 和 ceph.client.openstack.keyring 注入传播列表中定义的 RHOSP 服务。例如：

   $ oc patch openstackcontrolplane openstack --type=merge --patch '
   spec:
     extraMounts:
       - name: v1
         region: r1
         extraVol:
           - propagation:
             - CinderVolume
             - CinderBackup
             - GlanceAPI
             - ManilaShare
             extraVolType: Ceph
             volumes:
             - name: ceph
               projected:
                 sources:
                 - secret:
                     name: ceph-conf-files
             mounts:
             - name: ceph
               mountPath: "/etc/ceph"
               readOnly: true
   '
