Deployment of containerised OpenStack to bare metal using kolla and bifrost
650919f527
Fixes an issue where multiple NTP daemons could be running on the
overcloud hosts, due to Kolla Ansible deploying a chrony container by
default starting with the Rocky release.
Kayobe now overrides this default, to ensure that chrony does not conflict
with the NTP daemon deployed on the host. To use the containerised chrony
daemon instead, set ``kolla_enable_chrony`` to ``true`` in
``${KAYOBE_CONFIG_PATH}/kolla.yml``. This will also disable the host NTP
daemon.
To ensure that chrony is not running, Kayobe removes the chrony container
if ``kolla_enable_chrony`` is ``false`` in the following commands:
* ``kayobe overcloud service deploy``
* ``kayobe overcloud service reconfigure``
* ``kayobe overcloud service upgrade``
The play in Kayobe is tagged with ``stop-chrony``.

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.
