Bug Description

Docker 23.0 is out and it does not support --cluster-store.
What is the required configuration to get Zun working with Docker 23?

Zun uses kuryr-libnetwork, which relies on the --cluster-store option. There is no obvious workaround without this option.

The mitigation is to pin an older version of docker (like what we did to unblock the CI: https://review.opendev.org/c/openstack/zun/+/875203

The long-term solution is to migrate to containerd with CNI network model.

Unfortunately the mitigation isn't working for Debian Bookworm, which means kolla-ansible will have to drop Zun support for Bookworm until this issue is resolved.

ACK. The goal is to fix it in "C" release.
