One way to improve the performance of Ansible is through fact caching. Rather than gather facts in every play, we can configure Ansible to cache them in a persistent store. An example Ansible configuration for doing this is as follows: [defaults] gathering = smart fact_caching = jsonfile fact_caching_connection = ./facts fact_caching_timeout = 86400 While this mostly just works, there are a few places where we unconditionally gather facts using the setup module. This change modifies these to only gather facts when necessary. We no longer execute the MichaelRigart.interfaces role using become: true, since it may gather facts and we do not want it to do so as root. The role uses become where necessary.

Kayobe
Kayobe enables deployment of containerised OpenStack to bare metal.
Containers offer a compelling solution for isolating OpenStack services, but running the control plane on an orchestrator such as Kubernetes or Docker Swarm adds significant complexity and operational overheads.
The hosts in an OpenStack control plane must somehow be provisioned, but deploying a secondary OpenStack cloud to do this seems like overkill.
Kayobe stands on the shoulders of giants:
- OpenStack bifrost discovers and provisions the cloud
- OpenStack kolla builds container images for OpenStack services
- OpenStack kolla-ansible delivers painless deployment and upgrade of containerised OpenStack services
To this solid base, kayobe adds:
- Configuration of cloud host OS & flexible networking
- Management of physical network devices
- A friendly openstack-like CLI
All this and more, automated from top to bottom using Ansible.
