Mark Goddard 2071dc9a38 Allow more fine-grained groups for ironic, loadbalancer & network
Kayobe has fairly coarse-grained default groups - controller, compute,
etc, which work well in the majority of cases. Kolla Ansible allows much
more fine-grained placement on a per-service basis, e.g.
ironic-conductor. If the operator has taken advantage of this
fine-grained placement, then it is possible that some of the assumptions
in Kayobe may be incorrect. This is one downside of the split between
Kayobe and Kolla Ansible.

For example, Ironic conductor services may have been moved to a subset
of the top level 'controllers' group. In this case, we would not want
the Ironic networks to be mapped to all hosts in the controllers group -
only those running Ironic conductor services. The same argument can be
made if the loadbalancer services (HAProxy & keepalived) or Neutron
dataplane services (e.g. L3 & DHCP agents) have been separated from the
top level 'network' group.

This change abstracts the placement of Ironic conductor Ironic
inspector, loadbalancer and network services into separate variables,
rather than referencing the top level 'controllers' and 'network' groups
directly. These variables may be updated by the operator to match the
service placement.

Kayobe

image

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.
