===========================
Kolla-ansible Configuration
===========================

Kayobe relies heavily on kolla-ansible for deployment of the OpenStack control
plane. Kolla-ansible is installed locally on the ansible control host (the host
from which kayobe commands are executed), and kolla-ansible commands are
executed from there.

Local Environment
=================

Environment variables are used to configure the environment in which
kolla-ansible is installed and executed.
