Kayobe currently supports definition of various different networks - public, internal, tunnel, etc. These typically map to a VLAN or flat network, with an IP subnet. When a cloud exceeds the size of a single VLAN/subnet, this approach no longer works. One way to resolve this is to have multiple subnets that map to a single logical network, and provide routing between them. This is a similar concept to neutron's routed networks, but for the control plane. An issue arising from this is that if different hosts can have different network definitions for the internal and public networks, it is no longer trivial to use a network attribute [1] to specify the VIP address and FQDN. Furthermore, the play that generates Kolla Ansible's globals.yml containing the VIP and FQDN variables runs as localhost, which does not necessarily have the internal and public networks defined. To resolve this, we add global variables for the VIPs and FQDNs. The default values are as before, except in the case where HAProxy is disabled, which we no longer provide a useful default for. That configuration is very rarely used in practice, and the need to reference the IP address of a host in the network group makes it difficult to define safely.

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.
