Hi all,


 I've wanted to use ceph storage as a backend for nova, glance and cinder. I've succeded to use ceph for cinder and glance but I couldn't at nova.
I have saw this bug for "Stein" version --->  https://bugs.launchpad.net/nova/stein/+bug/1860990
After that, I've entered the nova-compute pod and I've run below commands;
apt install python-rbd
apt install python3-rbd
But it didn't work. I've gotten same error.
A solution must be on the K8s side. Do you have any of ideas about that?



Nova compute image;
