So the main methods of deploying openstack right now are Openstack-Ansible and Openstack Kolla, Both use Ansible to deploy everything and get the cluster up, but you /really/ have to dig into how things are setup if you are going to get a complicated install online. adding a new node into Kolla isn't too bad but can lead to the stack exploding at times. Upgrading is a huge PITA and I do opt to just wipe and replace most of the time.
