Most roles are not leveraging the jinja filters available. According to [1] filtering the list of services makes the execution faster than skipping the tasks. This patchset also includes some cosmetic changes to genconfig. Individual services are now also using a jinja filter. This has no impact on performance, just makes the tasks look cleaner. Naming of some vars in genconfig was changed to "service" to make the tasks more uniform as some were previously using the service name and some were using "service". Three metrics from the deployment were taken and those were - overall deployment time [s] - time spent on the specific role [s] - CPU usage (measured with perf) [-] Overall genconfig time went down on avg. from 209s to 195s Time spent on the loadbalancer role went down on avg. from 27s to 23s Time spent on the neutron role went down on avg from 102s to 95s Time spent on the nova-cell role went down on avg. from 54s to 52s Also the average CPUs utilized reported by perf went down from 3.31 to 3.15. For details of how this was measured see the comments in gerrit.

Kolla Ansible
The Kolla Ansible is a deliverable project separated from Kolla project.
Kolla Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla Ansible by reading the documentation online Kolla Ansible.
Get started by reading the Developer Quickstart.
