openstack - Centos7.8安装openstack mitaka版本，控制节点安装镜像服务glance，镜像包含问题

Question

Centos7.8安装openstack mitaka版本，控制节点安装镜像服务glance，镜像包含问题根据官方文档Mitaka官方文档操作，步骤3 使用QCOW2磁盘格式，裸容器格式上传镜像到镜像服务，和公共可见性，以便所有项目都可以访问它：我执行以下命令

openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public

输出中图像的大小为零。我应该如何检查这个问题

[root@controller ~]# openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public
