Centos7.8 install openstack mitaka version, control the node to install mirror service glance, the mirror contains problems
According to the official documentation https://docs.openstack.org/mitaka/install-guide-rdo/glance-verify.html operations, Step 3 Upload the image to the image service using the QCOW2 disk format, bare container format, and public visibility so all projects can access it:
I execute the following command
Openstack image create "cirros" \
- the file cirros 0.3.4 - x86_64 - disk. Img \
--disk-format qcow2 --container-format bare \
- public
The size of the image in the output is zero. How should I check this problem
