Our current openstack deployment utilizes a simple flat networking setup that requires usage of a now seemingly 'deprecated' / 'experimental' technology in upstream Openstack {T326373}. It also prevents us from adopting useful features, such as tenant networking {T270694}, Octavia (load balancers), that cause issues or limitations when adopting new features. For example, {T321220}.
Therefore, as noted in T326373#8508661, we should plan a migration off a linuxbridge agent. To do so, we need to redeploy Openstack. Given the age of our Openstack deployment, and the fact we do not currently have a repeatable deployment (that is, the ability to redeploy our cloud on demand), let's explore current methods utilized by upstream and other cloud operators.
Consider:
* Kolla-ansible
* Kayobe
* TripleO
* Bifrost
