Current Series Release Notes

12.5.0-14

Deprecation Notes

  • As the fast forward upgrade workflow to skip multiple releases now relies on the very same upgrade_tasks, there is no need to mantain the fast_forward_upgrade_tasks, as well as any of its references.

Bug Fixes

  • Previously, HorizonDebug and Debug parameters change the value of horizon::django_debug. However, those parameters didn’t set DEBUG log level to horizon logger components. By this change, if those are true, horizon::log_level is set to ‘DEBUG’.

12.5.0

New Features

  • Add new BarbicanClient tripleo service for configuring DCN/Edge nodes to access a barbican service running in the control plane. The client service is disabled by default, and can be enabled by including the environments/services/barbican-edge.yaml environment file when deploying a DCN/Edge stack.

  • Added new PublicTLSCAFile parameter, that is used to set the ca cert in clouds.yaml for keystone public endpoint. This defaults to empty string (‘’) assuming that the certs are already trusted.

  • Add GlanceImagePrefetcherInterval parameter to run periodic job which fetches the queued images for caching in cache directory, when image cache is enabled.

  • Add boolean parameter NovaSchedulerQueryPlacementForAvailabilityZone that sets scheduler/query_placement_for_availability_zone parameter. It allows the scheduler to look up a host aggregate with metadata key of availability zone set to the value provided by incoming request, and request result from placement be limited to that aggregate. Default value for NovaSchedulerQueryPlacementForAvailabilityZone is false.

  • Adds the “OctaviaLogOffload” setting to enable amphora log offloading.

  • Added TCP Segmentation Offload (TSO) support for ovs-dpdk.

  • Added support for VxFlexOS cinder block storage backend driver

  • A new Heat parameter ‘ZaqarWsTimeout’ exposes the Puppet variable ‘tripleo::haproxy::zaqar_ws_timeout_tunnel’. This allows operators to configure the Mistral API timeout. It currently defaults to four hours.

Deprecation Notes

  • Usage of the option NeutronFirewallDriver which was used to set firewall_driver config option in the Neutron server’s config is now deprecated. Firewall driver should be set per agent in the agent’s config. It can be done using NeutronOVSFirewallDriver option. Option in the Neutron server was in there just for backward compatybility reasons but since Newton release all Neutron agents are reporting to the server what firewall driver is used so there is no need to keep this legacy, server side option anymore.

  • Paunch was deprecated in Ussuri and is now being retired, to be fully replaced by the new tripleo-ansible role, tripleo_container_manage.

  • Support for Neutron FUJITSU plugin has been removed.

  • Resource OS::TripleO::Services::CinderBackendScaleIO is no longer supported. Use the new resource OS::TripleO::Services::CinderBackendDellEMCVxFlexOS.

  • NeutronSriovNumVFs parameter to configure the VFs for SR-IOV is removed. Instead, use the network interface types sriov_pf in the nic configs to configure the VFs for SR-IOV devices.

Bug Fixes

  • Ensure the barbican Key Manager settings are configured on DCN/Edge nodes when the barbican service is deployed in the control plane. See bug 1886070.

Other Notes

  • Ensure we’re using only /run location, since /var/run is a symlink to /run

  • The ValidateNtp has been removed from the all nodes validation configuration. During the time sync configuration we already do a check to ensure the ntp servers are available. If they are not we will fail with an appropriate message. The ValidateNtp option came from a time before we could fail in a more explicit way.
