Hello Anirudh,

Bare metal compute nodes are indeed controlled by the Ironic service deployed inside OpenStack, rather than by Kayobe and its seed services, which are used for the control plane and virtualized compute nodes. Kayobe offers commands for managing the bare metal nodes, but the actual work is being done by the Ironic service: https://docs.openstack.org/kayobe/latest/administration/bare-metal.html

The `openstack baremetal` commands can also be used to interact with Ironic, which will manage the lifecycle of the bare metal nodes. For more information you should read the Ironic documentation at https://docs.openstack.org/ironic/latest/

Best wishes, Pierre Riteau

Hi Pierre,

Thanks for your reply.

I was going through the PPT https://docs.google.com/presentation/d/1wFittxJwRBH6IyCr4Ext2ZdBuNr42xfpanFd...

In the Slide #24, it talks about Virtualized Compute and Bare Metal Compute

[image: image.png]

As per my understanding, virtualized compute will be the hardwares on which VM/VNFs would get spawned.

Bare Metal Compute will be the ones which would be provisioned using Ironic Service? Once it is being provisioned, commands like "openstack baremetal node create..." etc mentioned in the below link would run on those for installing User Specific Workload image?

https://docs.openstack.org/python-ironicclient/latest/cli/osc_plugin_cli.htm...

Is my understanding correct?

Hi Anirudh,

Kayobe is indeed designed to work with a specific release of Kolla Ansible, which in turns deploys a specific release of OpenStack.

Note however that Kolla Ansible and Kayobe are both deliverables of the same "Kolla" OpenStack project team. Both softwares are developed together during the release cycle and are generally released at the same time. Kayobe doesn't wait for Kolla Ansible to be released to start preparing its own release.

Hi Team,

Whenever a new version of openstack is released in the market, Kayobe also updates its release accordingly.

I was going through the installation guide and found Kayobe is dependent on Kolla-Ansible as well.

The link https://docs.openstack.org/kayobe/latest/contributor/releases.html suggests that kayobe needs to Synchronise with Kolla Ansible feature flags Synchronise with Kolla Ansible inventory¶ https://docs.openstack.org/kayobe/latest/contributor/releases.html#synchronise-with-kolla-ansible-inventory

So in case openstack releases it's newer version, does kayobe wait for kolla-ansible to update to the new release and then starts upgrading its release?
