This is what I did to integrate kolla-ansible with ceph. Make sure all the PATHs are correct. cinder_backend_ceph: "yes" enable_cinder: "yes" enable_cinder_backup: "no" ceph_cinder_user: "os2-cinder" ceph_cinder_keyring: "client.os2-cinder.keyring" # ls -l /etc/kolla/config/cinder/ total 8 -rw-r--r-- 1 root root 284 Oct 17 02:35 ceph.conf drwxr-xr-x 2 root root 4096 Oct 30 04:50 cinder-volume # ls -l /etc/kolla/config/cinder/cinder-volume/ total 4 -rw-r--r-- 1 root root 68 Oct 30 04:46 ceph.client.os2-cinder.keyring # ls -l /etc/kolla/config/nova/ -rw-r--r-- 1 root root 68 Oct 30 04:50 /etc/kolla/config/nova/ceph.client.os2-cinder.keyring -rw-r--r-- 1 root root 284 Oct 30 04:51 /etc/kolla/config/nova/ceph.conf On Thu, Dec 11, 2025 at 6:19 AM Luca De Marco <LDeMarco@sinthera.com> wrote:
Hi Winicius
I checked the globals.yml and my configuration for cinder and nova keyring are below
*ceph_cinder_keyring: "client.{{ ceph_cinder_user }}.keyring"* *ceph_nova_keyring: "{{ ceph_cinder_keyring }}"*
The filepath is rightly in /etc/kolla/config/nova/ceph.client.cinder.keyring
But nova_compute container don’t goes up with the error below
*ERROR MissingRequiredSource: /var/lib/kolla/config_files/ceph.client.cinder.keyring file is not found*
Any idea ?
Kind Regards
Luca

Hi Luca,
Check `ceph_nova_keyring` and `ceph_cinder_keyring` variables in your globals.yml.
Kolla adds "ceph" at the start of the variable name to find the file in node_config_directory. So, if you have
ceph_nova_keyring: client.cinder.keyring
The filepath must be "/etc/kolla/config/nova/ceph.client.cinder.keyring", for example.
Regards, Winicius.

Hi guys,
In my first openstack deploy I facing an error in deployment phase. The bootstrap-servers phase and the prechecks phase working fine but the deploy phase stop to work in nova-compute task deployment with the following error
[ERROR]: Task failed: Action failed. Origin: /root/kolla-venv/share/kolla-ansible/ansible/roles/nova-cell/tasks/wait_discover_computes.yml:24:7
22 expected_compute_service_hosts: "{{ virt_compute_service_hosts + ironic_compute_service_hosts }}" 23 block: 24 - name: Waiting for nova-compute services to register themselves
looking for the nova-compute docker logs I found this event
ERROR MissingRequiredSource: /var/lib/kolla/config_files/ceph.client.cinder.keyring file is not found
I would you like to point out that the ceph keyring are created and copied to /etc/koll/config/nova in deployment host and /etc/ceph in all openstack host. Some one could help me for fix the issue ?
Regards Luca
