At the moment, Watcher can use a single bare metal provisioning service: Openstack Ironic. We're now adding support for Canonical's MAAS service [1], which is commonly used along with Juju [2] to deploy Openstack. In order to do so, we're building a metal client abstraction, with concrete implementations for Ironic and MAAS. We'll pick the MAAS client if the MAAS url is provided, otherwise defaulting to Ironic. For now, we aren't updating the baremetal model collector since it doesn't seem to be used by any of the existing Watcher strategy implementations.
