Comment 1 for bug 1586148

It would appear that, due to the container name change in the log, this was an upgrade from Liberty->Mitaka. It would be pertinent for you to be using the appropriate *published* upgrade guide for Mitaka instead of that in the master branch. Mitaka upgrade documentation is published here: http://docs.openstack.org/developer/openstack-ansible/mitaka/upgrade-guide/index.html

Secondly, there are patches in progress to deal with name changes. Please check https://review.openstack.org/#/q/branch:stable/mitaka+project:%255Eopenstack/openstack-ansible.*+status:open to see their status.
