In reply to Kon Georgopoulos.

Depends what you mean when you refer to "deployment methods". If you are talking about deployment of the Openstack services themselves (ie. Kolla), I think containers will make life a lot easier for lifecycle management. If you are talking about deployment of the applications on top of OpenStack (ie. Magnum) then I think that containers will a very popular option but traditional app deployment will continue to have its attractions, so the two will coexist.
