For overcloud commands involving Bifrost (e.g. overcloud provision), we use the Bifrost dynamic inventory. This runs bifrost_inventory.py which gathers node and port information for all bare metal hosts. Because this gets executed for each node in our inventory, it produces a large number of API requests to Ironic, which grows as the number of hosts increases. Halve the number of calls using the BIFROST_NODE_NAMES environment variable, which restricts fetching port information to just the node being queried. bifrost_inventory.py still performs one call for each node, which must be fixed separately in Bifrost [1]. Time to query overcloud nodes' hardware introspection data for 44 hosts: * before patch: 823 seconds * after patch: 415 seconds With the patch to Bifrost [1], this is further reduced to 46 seconds.

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.
Features
- Heavily automated using Ansible
