Ubuntu OpenStack Dev Summary – 18th December 2018

Welcome to the Ubuntu OpenStack development summary!

This summary is intended to be a regular communication of activities and plans happening in and around Ubuntu OpenStack, covering but not limited to the distribution and deployment of OpenStack on Ubuntu.

If there is something that you would like to see covered in future summaries, or you have general feedback on content please feel free to reach out to me (jamespage on Freenode IRC) or any of the OpenStack Engineering team at Canonical!

OpenStack Distribution

Stable Releases

Current in-flight SRU’s for OpenStack related packages:

Ceph 12.2.1

OpenvSwitch 2.8.1

nova-novncproxy process gets wedged, requiring kill -HUP

Horizon Cinder Consistency Groups

Recently released SRU’s for OpenStack related packages:

Percona XtraDB Cluster Security Updates

Pike Stable Releases

Ocata Stable Releases

Ceph 10.2.9

Development Release

Since the last dev summary, OpenStack Queens Cloud Archive pockets have been setup and have received package updates for the first and second development milestones – you can install them on Ubuntu 16.04 LTS using:

sudo add-apt-repository cloud-archive:queens[-proposed]

OpenStack Queens will also form part of the Ubuntu 18.04 LTS release in April 2018, so alternatively you can try out OpenStack Queens using Ubuntu Bionic directly.

You can always test with up-to-date packages built from project branches from the Ubuntu OpenStack testing PPA’s:

sudo add-apt-repository ppa:openstack-ubuntu-testing/queens

Nova LXD

No significant feature work to report on since the last dev summary.

The OpenStack Ansible team have contributed an additional functional gate for nova-lxd – its currently non-voting, but does provide some additional testing feedback for nova-lxd developers during the code review process.  If it proves stable and useful, we’ll make this a voting check/gate.

OpenStack Charms

Ceph charm migration

Since the last development summary, the Charms team released the 17.11 set of stable charms; this includes a migration path for users of the deprecated ceph charm to using ceph-mon and ceph-osd. For full details on this process checkout the charm deployment guide.

Queens Development

As part of the 17.11 charm release a number of charms switched to execution of charm hooks under Python 3 – this includes the nova-compute, neutron-{api,gateway,openvswitch}, ceph-{mon,osd} and heat charms;  once these have had some battle testing, we’ll focus on migrating the rest of the charm set to Python 3 as well.

Charm changes to support the second Queens milestone (mainly in ceilometer and keystone) and Ubuntu Bionic are landing into charm development to support ongoing testing during the development cycle.  OpenStack Charm deployments for Queens and later will default to using the Keystone v3 API (v2 has been removed as of Queens).  Telemetry users must deploy Ceilometer with Gnocchi and Aodh as the Ceilometer API has now been removed from charm based deployments and from the Ceilometer codebase.  You can install the current tip of charm development using the the openstack-charmers-next prefix for charmstore URL’s – for example:

juju deploy cs:~openstack-charmers-next/neutron-api

ZeroMQ support has been dropped from the charms; having no know users and no functional testing in the gate and having issued deprecation warnings in release notes it was time to drop the associated code from the code base.  PostgreSQL and deploy from source are also expected to be removed from the charms this cycle.

You can read the full list of specs currently scheduled for Queens here.


The last stable charm release went out at the end of November including the first stable release of the Gnocchi charm – you can read the full details in the release notes.  The next stable charm release will take place in February alongside OpenStack Queens, with a release shortly after the Ubuntu 18.04 LTS release in May to sweep up any pending LTS support and fixes needed.

IRC (and meetings)

As always, you can participate in the OpenStack charm development and discussion by joining the #openstack-charms channel on Freenode IRC; we also have a weekly development meeting in #openstack-meeting-4 at either 1000 UTC (odd weeks) or 1700 UTC (even weeks) – see http://eavesdrop.openstack.org/#OpenStack_Charms for more details.  The next IRC meeting will be on the 8th of January at 1700 UTC.

And finally – Merry Christmas!
