There is currently no coverage of upgrades in CI, which leaves us open to regression in this infrequently tested but crucial area. This change adds the required scripts and Zuul configuration. A control plane is first deployed using the Kayobe stable/pike branch and associated default configuration. The control plane is tested by deploying then deleting a server instance. An upgrade to Queens is performed, using the Kayobe master branch, or code in review if applicable. The upgraded control plane is tested by deploying then deleting a second server instance. A workaround was required to restart the nova_compute service after the upgrade, since the SIGHUP sent to it by Kolla Ansible during upgrade appeared to be putting it into a degraded state. A future improvement to this test could be to leave a server instance running during the upgrade. Change-Id: I0e595524e39d1131fe3ec6aaf2aeec3ff3d6a536 Story: 2003472 Task: 24732
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.
