并于Kolla的介紹這里不進行過多的闡述，網上有很多文檔。本文主要是針對最新版本的Kolla，解決單節點無法部署ceph-osd問題（在測試時發現多節點也無法部署Ceph-osd）。在最新版本的kolla中，官網已經給出要下架Ceph的公告，具體信息如下圖：
此片文章會通過修改kolla-ansible源碼解決不能部署ceph問題。
部署具體過程如下：

在部署的過程中，我們可以看到在執行ceph-osd相關任務時，沒有正確執行的反饋，具體如上圖。此時我們可以通過ceph osd tree 命令來查看
[root@openstack ~]# docker exec ceph_mon ceph osd tree
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 0 root default
[root@openstack ~]# docker exec ceph_mon ceph df
RAW STORAGE:

等待一段時間后，部署完成，也沒有報錯。
