Deployment of containerised OpenStack to bare metal using kolla and bifrost
f618a2c4b8
If using a CentOS 8.2 bifrost_deploy image on a CentOS 8.1 seed host, we
may see an error such as the following:
TASK [Ensure the overcloud host image has bogus name server entries removed]
fatal: [seed]: FAILED!
Running virt-customize with more debug in the Bifrost container, we see
this output:
qemu-kvm: error: failed to set MSR 0x48e to 0xfff9fffe04006172
qemu-kvm: /builddir/build/BUILD/qemu-4.2.0/target/i386/kvm.c:2695: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
This appears to be an incompatibility between qemu/libvirt in CentOS 8.1
and 8.2.
This change fixes the issue for new deployments by updating the seed VM
image to CentOS 8.2. Existing deployments will need to update packages
on the seed host to match the bifrost_deploy container.

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.
