Train Series Release Notes¶
This release supports placement integration.
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.
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
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,
falsewhich means Zun compute agent will create its own resource provider for the compute node.
