Hey, So the doc you're referring to assumes OS reinstallation for hosts during the upgrade. As you've rightfully mentioned - upgrade of host OS does not actually result in LXC containers upgrade. There are multiple ways forward with that. Eventually, you can run do-release-upgrade inside of containers independently from the host. Or, you can re-create the containers per-control. In order to re-create all containers on a specific control node, you can run: * openstack-ansible lxc-containers-destroy.yml --limit ${control}-host_containers * openstack-ansible lxc-containers-create.yml --limit ${control}-host_containers,${control} So merging that with the doc mentioned, Deploying Infrastructure Hosts section specifically, you need to replace step 2 with the commands above. пн, 26 мая 2025 г. в 14:43, Danish Khan <danish52.jmi@gmail.com>:

Dear Team,

I am trying to upgrade Operating system of Infra node from ubuntu 20 to ubuntu 22.

And I am following below docs for same:

https://docs.openstack.org/openstack-ansible/2023.1/admin/upgrades/distribut...

When I run:

openstack-ansible setup-hosts.yml --limit localhost,reinstalled_host*

I thought it would upgrade OS of LXC containers as well. I can see ubuntu-22-amd64 in /var/lib/lxc/ and /var/lib/machines/

I can see ubuntu-22-amd64 even when I run lxc-ls command.

Should I destroy and recreate lxc containers one by one to upgrade it to ubuntu 22? or is there any playbook which can take care of this?

Regards,

Danish Khan
