Train Series Release Notes¶
RabbitMQ and Erlang packages are now installed from
packagecloud.io(and PPA for Ubuntu) since
bintray.comis getting shut down May 1st, 2021.
Ubuntu based images use APT mirrors now. May affect builds done behind http proxies.
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.
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.
Almanach and Dragonflow images are no longer available for Debian/Ubuntu.
networking-hypervpackage is no longer installed in the
kuryr-libnetworkimage is no longer available.
helm-repositoryimage is now unbuildable due to the chart repository being gone. The image was deprecated and is not known to be used by any tooling.
Fixes mixed RabbitMQ and Erlang package sources on CentOS 8 (Train only). Those could lead to RabbitMQ cluster instability in certain circumstances. LP#1884034
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. Deletion occurs after 30 days or 3000 MB log files size - whichever comes first.
Fixes MariaDB incremental backup failure when full backup was not created the same day. LP#1897948
Fixes builds on CentOS 8.3 failing due to renamed repos. Notice Kolla now no longer supports CentOS 8.2 and below. LP#1907213
Fixes an issue with the
kolla_set_configs --checkcommand when the source is a directory. LP#1890567
Fixes an issue with the Masakari dashboard where policies were not loaded correctly.
masakari-monitorsimage on CentOS 8.
nova-compute uses daxio to cleanup vpmem backend device on instance delete. If the daxio binary is missing in the nova-compute container instance delete fails. daxio is provided in centos via daxio, in ubuntu via the pmdk-tools package.
Fixes an issue which can block the Monasca Fluentd output plugin. LP#1889065
Adds Elasticsearch Curator for managing aggregated log data.
The Logstash image has been upgraded from Logstash 2 to Logstash 6 for Centos 7 and Centos 8 only.
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.
Adding ndctl package to nova-compute to expose NVDIMM namespaces to guests. The package is needed to manage PMEM namespaces.
collectdRHEL8-based image. dpdk_telemetry plugin collects DPDK ethernet device metrics via dpdk_telemetry library. Logparser is plugin for filtering and parsing log messages.
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.
kibana6images for CentOS 7 and 8 only. These images are used to provide compatibility between versions in CentOS 7 and 8 images. These images will only be available in the Train release.
AArch64 images using CentOS 8 as base system are not supported in Train. This may be fixed later in release cycle as we need CentOS 8.2 release.
The following images are supported by CentOS 7 but lack suitable packages in CentOS 8, and are not supported for CentOS 8:
The following images are supported by CentOS 7 but are not supported for CentOS 8 as they have been dropped in Ussuri:

kolla-build, but now they are.
tricklepackage is no longer available for CentOS 8, and has been removed from the CentOS 8 Freezer images.
Adds a new
rabbitmq-3.7.24image for CentOS 7 only. This image is used to provide compatibility between RabbitMQ versions in CentOS 7 and 8 images. This image will only be available in the Train release.
process-checksplugins from the
sensu-clientimage. These plugins have a dependency on version
0.6.3of the Ruby gem
english, which has been “yanked” from rubygems.org.
Adds openssh-clients to ironic conductor container build to enable ansible deploy interface to function properly.
Adds python3-systemd package to ironic-conductor source based container to allow the Ansible deploy interface to function correctly. Fixes bug #1861427
Fix inability to run UEFI-based images/instances by installing UEFI packages also in nova-libvirt image which is not based on nova-base. LP#1814552
Keystone bootstrap could produce invalid json. LP#1866017
Fixes the MAX_NUMBER variable usage when running the database online migrations for cinder.
Fixes Glance inability to use Cinder NFS backend for images by including NFS client components in the Glance API image. LP#1868574
vitrage-persistorimage, required by Vitrage deployments for storing data. LP#1869319

Fixes an issue with keystone bootstrap where an error message emitted by the
keystone-manage bootstrapcommand is hidden. See bug 1855701 for details.
Converts deprecated command
rally db. LP#1856693
Fixes swift-object-expirer for Debian and Ubuntu binary images. LP#1859607
9.0.0 release is the first release in the Train cycle. Highlights include new images for the Masakari instance High Availability service and Qinling which provides Function as a Service. Ubuntu and Debian source images are now using Python 3.
Adds HAcluster images. These images contain services supporting High Availability such as Corosync, Pacemaker, Pacemaker Remote and PCS.
HAcluster will not handle any OpenStack control plane resources, it will be used as third party for OpenStack Masakari for example to handle instance failover following a Nova compute crash.
Adds Qinling images. Qinling is an OpenStack project to provide “Function as a Service”. This project aims to provide a platform to support serverless functions.
Adds configration option
use_dumb_init, with default value of
True. This can be use to avoid the of
dumb-initas the container entrypoint, using
kolla_startdirectly instead. This option can also be disabled via the
kolla-build --nouse-dumb-initCLI argument.
Adds Masakari images. Masakari provides Instances High Availability Service for OpenStack clouds by automatically recovering failed Instances.
Improves the skipped images feature, allowing filtering based on used image distribution, installation type and processor architecture.
ENTRYPOINTstatement outside of the
dumb_init_installationJinja block in the base image. Overriding this block to install
dumb-initby another method no longer requires repeating the
ENTRYPOINTstatement. Users wishing to avoid the use of
dumb-initaltogether can now use the
fluentdimage no longer includes the
kubernetes_metadata_filterplugin. It is not used by Kolla downstream projects (Kolla-Ansible, TripleO, OpenStack-Helm). It can be installed by customizing
xtrabackupimage has been removed because XtraBackup is no longer compatible with the versions of MariaDB shipped with Kolla images. Mariabackup should be used instead.
craneimage which was deprecated in the Stein cycle has been removed.
nova-consoleauthimage has been removed. This service has been deprecated in nova since Rocky and has not been used by other nova services since.
nova-placement-apiimage was renamed to
placement-apiin the Stein release, and has now been removed.
Removes support for building OracleLinux container images.
tripleo-uicontainer is no longer built as the project has been retired.
The Neutron LBaaS project was retired. Upgrading to deployment to Train release will not upgrade Neutron LBaaS. Learn more about its retirement and Octavia as its successor at https://wiki.openstack.org/wiki/Neutron/LBaaS/Deprecation
In Ubuntu images, MariaDB has been upgraded from 10.1 to 10.3. As usual, ensure that all data has been backed up prior to upgrading.
en_US.UTF-8is set as the default locale (
LANG) for images. This affects both build- and run-time. Distributions supported by Kolla default to UTF-8 locale in installs so this change should provide a more expected experience. It makes images Unicode-friendly.
Monasca now supports InfluxDB 1.7.x, the default version provided by Kolla. Monasca users can follow the InfluxDB upgrade notes in the guide: https://docs.influxdata.com/influxdb/v1.7/administration/upgrading/
The Almanach images are deprecated and will be removed in the Ussuri cycle. This includes
almanach-collector. These are not used by Kolla downstream projects.
dindimage is deprecated and will be removed in the Ussuri cycle. It is not used by Kolla downstream projects (Kolla-Ansible, TripleO, OpenStack-Helm). It has not seen recent usage and the upstream project seems no longer active.
The Dragonflow images are deprecated and will be removed in the Ussuri cycle. This includes
dragonflow-publisher-service. These are not used by Kolla downstream projects.
Kubernetes-related images are deprecated and will be removed in the Ussuri cycle. They are not used by Kolla downstream projects (Kolla-Ansible, TripleO, OpenStack-Helm). They were used in the Kolla-Kubernetes project which was retired in the Rocky cycle. The deprecated images include:
install_kubectlmacro is deprecated as well and, along with it, the
kubectlcommand because it is of limited usefulness being pinned to an old version. Magnum end-users use an externally-provided
kubectl. Please note this deprecation does not affect Magnum nor Qinling support.
In prior versions of InfluxDB, including 1.3.x, InfluxDB incorrectly ignored tag names starting with a leading underscore. In Monasca this broke tenant isolation because queries containing where _tenant_id = ‘some_id’ where not scoped to the tenant_id. Upgrading to InfluxDB 1.7.x solves this issue.
Fixes unavailability of an etcd3-compatible tooz coordination driver in Ubuntu binary images by installing
python3-etcd3gw. See bug 1852086 for details.
