When generating a bundle with the command below creating openstack containers, openstack container create <container_name>, does not work as expected because of the missing relation between vault and ceph-rgw.
./generate-bundle.sh --defaults --release yoga --openstack-dashboard --num-compute 3 --ceph --ceph-rgw --num-ceph-mons 3 --num-osds-per-host 3 --name mystack
Adding the relation
