This release supports placement integration.
features:
- |
In this release, Zun compute agent will report local resource
availability/utilization to placement API.
In addition, Zun scheduler will get allocation candidates
from placement API and claim container allocation in placement.
upgrade:
- |
Since this release, operators need to configure each compute node
that runs both Zun compute agent and Nova compute agent as follows::
[compute]
host_shared_with_nova = true
By setting ``host_shared_with_nova`` to ``true``, Zun compute agent and
Nova compute agent will share a resource provider for the compute node
in placement. In particular, both Nova instances and Zun containers might
claim allocation on the same resource provider.
By default, ``host_shared_with_nova`` is ``false`` which means Zun
compute agent will create its own resource provider for the compute node.
