Fix support for kolla install in
Fixes issues arising from the lack of Debian updates repo being enabled. LP#1931544
Fixes Mistral source images to respect upper-constraints.
Debian images enable the Debian updates repo now. This is aligned with the base Debian image.
Add a Monasca app plugin for the Monasca fork of Grafana. Plugin provides screens for viewing or configuring: Alarm Definitions, Alarms and Notifications
Kolla now no longer supports CentOS 8.2 and below. This is to support CentOS 8.3 without extra workarounds (please see the fixes section for more details). The promise is to support the latest CentOS 8 release which is 8.3 now.
Source based builds will now install OpenStack projects code from stable tarballs, compared to versioned (released point versions) ones as before.
Fixes the FC Cinder backend usage in Nova. LP#1884484
Logstash 6 introduced in Centos 8 in Train release comes with log4j2 configuration that does not remove old compressed logs after rotation https://github.com/elastic/logstash/issues/11883 Log rotation config backported from Logstash 7 - Combination of Size Based and Time Based policies.

The Logstash image has been upgraded from Logstash 2 to Logstash 6.
Fixes Ceilometer deployment and upgrade failing due to wrong mode of argument passing applied to the
Drop systemd support from nsswitch.conf on RHEL-based distros. This avoids unneeded systemd nss lookups inside containers and it also avoids possible selinux denials when a container bind mounts /run and makes the dbus socket available inside the container only to be denied by selinux on the host.
Fixes an issue with loading Storm and Monasca Thresh when using Centos8 containers.
Fixes a bug in Monasca Agent Statsd which causes it to fail under Python 3.
10.0.0 release is the first release in the Ussuri cycle.

neutron-mlnx-agentimage for the Neutron Mellanox agent.
--quietswitch to disable printing of image build logs.
Add support for building
zun-cni-daemon. This is a new daemon for implementing CNI plugin for Zun.
collectdRHEL-based image. The
dpdk_telemetryplugin collects DPDK Ethernet device metrics via the
logparseris a plugin for filtering and parsing log messages.
Allow operators to use custom parameters with the
ceilometer-upgradecommand. This is quite useful when using the dynamic pollster subsystem; that sub-system provides flexibility to create and edit pollsters configs, which affects Gnocchi resource-type configurations. However, Ceilometer uses default and hard-coded resource-type configurations; if one customizes some of its default resource-types, they can get into trouble during upgrades. Therefore, the only way to work around it is to use the
Adds support for CentOS 8 as a base container image. This is the only major version of CentOS supported from the Ussuri release. The Train release supports both CentOS 7 and 8 images, and provides a route for migration.
collectdRHEL-based image. This allows collectd to collect PCI Express errors data from Device Status in Capability structure and from Advanced Error Reporting Extended Capability where available.
collectdRHEL-based image. This allows to collect Intel PMU (performance counters) data via
netcontroldimage for Open vSwitch.
Adds an –enable-unbuildable option to ignore the internal list of unbuildable images. It is useful in two situations: building for a new distribution/architecture or generation of templates (with
--templates-onlyoption) when all templates are needed no matter being buildable or not.
ndctlpackage to the
nova-computeimage to expose NVDIMM namespaces to guests. The package is needed to manage PMEM namespaces.
AArch64 images using CentOS as base system are not supported in Ussuri. This may be fixed when CentOS 8.2 is released.
Cyborg Agent no longer includes OPAE SDK. The version was outdated and currently supported platforms do not have ready-to-use binaries. This change was required to make Cyborg buildable.
CentOS 7 is no longer supported as a base container image. CentOS users should migrate to CentOS 8. The Train release supports both CentOS 7 and 8 images, and provides a route for migration.
The following images were supported by CentOS 7 but lack suitable packages in CentOS 8, and are no longer supported for CentOS:
Debian images are using Ceph 14 ‘nautilus’ like other distributions.

tgtd) has been removed for CentOS/RHEL 8. In CentOS/RHEL 7 and beyond LIO kernel subsystem can be used instead of the
tgtdimage is no longer available for CentOS/RHEL 8.
Python 2.7 support has been dropped. The last release of Kolla to support Python 2.7 is OpenStack Train. The minimum version of Python now supported by Kolla is Python 3.6.
The way of handling external repositories has changed. All such repos are now disabled by default. The
enable_extra_reposmacro is used to enable them by name. Repositories names are defined in the
Changes the behaviour of the
--skip-parentsflags. Previously these were not applied if no regular expression or profile argument was provided to
kolla-build, but now they are.
tricklepackage is no longer available for CentOS 8, and has been removed from the CentOS 8 Freezer images.
The way of generating templates (with
--templates-onlyoption) is changed. By default only buildable ones are generated. If all templates are needed then
--enable-unbuildableoption must be used.
Changes the default value of the
[DEFAULT] tarballs_baseconfiguration option from
https://tarballs.opendev.org. Since the OpenDev site is namespaced, the default source image tarball locations have been updated to include the
/openstack(or in a few cases
/x) URL path.
Upgrades RabbitMQ to 3.8. See blueprint for details.
Kolla Ceph container images have been removed. Please use another source of Ceph container images, such as ceph-container
Images deprecated in the Train cycle have been removed. These include almanach, dind, dragonflow, helm and kubernetes images.
The Ansible modules
kolla_keystone_servicehave been removed from the
kolla-toolboximage. These were previously used by Kolla Ansible, which switched to the upstream Ansible modules in the Train release.
The Monasca Log API merged into the Monasca API codebase in the Train release and the
monasca-log-apiimage has therefore been removed.
As part of the support for using the unified Monasca API for logs, the Fluentd Monasca output plugin has been upgraded. Any custom Fluentd configuration which forwards logs to Monasca will need to be updated.
Support for Skydive images for aarch64 and ppc64le has been dropped. Upstream builds own images for a wide selection of architectures. Binaries are provided only for x86-64.
