Comment 1 for bug 2007142

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.
