Kolla recently upgraded bifrost from 7.0.0 to 7.1.0 on the stable/train branch. This switched to IPA builder to build the IPA image, and introduced a rename of the IPA kernel file from ipa.vmlinuz to ipa.kernel, which breaks overcloud provisioning. The iPXE kernel download fails with a 404, since Kayobe introspection rules use ipa.vmlinuz for the driver_info.deploy_kernel URL. This change works around the issue by setting two Bifrost variables, ipa_kernel and ipa_kernel_url, to reference the old kernel filename of ipa.vmlinuz. This works both in the case where the image is downloaded from a URL (ipa_kernel sets the destination file name), and where it is built via 'kayobe seed deployment image build' (kayobe uses the legacy ironic-agent DIB element rather than IPA builder, which creates a hardlink to ipa.vmlinuz). We chose the above approach rather than switching to IPA builder due to it being a less risky change at a time close to release. A future release of Kayobe should switch to IPA builder, but this will be a larger effort.

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.
