I mentioned the related issue back in January:


Adding a floating IP to an instance is possible using OSC CLI, it's 
essentially something like:

a) get the server id (openstack server show/list)
b) get the port id using the server id (openstack port list --device-id 
c) assign the floating IP to the port (openstack floating ip set --port
