并于Kolla的介绍这里不进行过多的阐述，网上有很多文档。本文主要是针对最新版本的Kolla，解决单节点无法部署ceph-osd问题（在测试时发现多节点也无法部署Ceph-osd）。在最新版本的kolla中，官网已经给出要下架Ceph的公告，具体信息如下图：
此片文章会通过修改kolla-ansible源码解决不能部署ceph问题。
部署具体过程如下：

在部署的过程中，我们可以看到在执行ceph-osd相关任务时，没有正确执行的反馈，具体如上图。此时我们可以通过ceph osd tree 命令来查看
[root@openstack ~]# docker exec ceph_mon ceph osd tree

[root@openstack ~]# docker exec ceph_mon ceph df
