Ubuntu OpenStack Dev Summary – 22nd May 2017

Welcome to the first ever 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

Development Release

OpenStack Pike b1 is available in Xenial-Pike UCA (working through proposed testing in Artful).

Open vSwitch 2.7.0 is available in Artful and Xenial-Pike UCA.

Expect some focus on development previews for Ceph Luminous (the next stable release) for Artful and the Xenial-Pike UCA in the next month.


OpenStack Snaps

Progress on producing snap packages for OpenStack components continues; snaps for glance, keystone, nova, neutron and nova-hypervisor are available in the snap store in the edge channel – for example:

sudo snap install --edge --classic keystone

Snaps are currently Ocata aligned; once the team have a set of snaps that we’re all comfortable are a good base, we’ll be working towards publication of snaps across tracks for OpenStack Ocata and OpenStack Pike as well as expanding the scope of projects covered with snap packages.

The edge channel for each track will contain the tip of the associated branch for each OpenStack project, with the beta, candidate and release channels being reserved for released versions. These three channels will be used to drive the CI process for validation of snap updates. This should result in an experience something like:

sudo snap install --classic --channel=ocata/stable keystone

or

sudo snap install --classic --channel=pike/edge keystone

As the snaps mature, the team will be focusing on enabling deployment of OpenStack using snaps in the OpenStack Charms (which will support CI/CD testing) and migration from deb based installs to snap based installs.


Nova LXD

Support for different Cinder block device backends for Nova-LXD has landed into driver (and the supporting os-brick library), allowing Ceph Cinder storage backends to be used with LXD containers; this is available in the Pike development release only.

Work on support for new LXD features to allow multiple storage backends to be used is currently in-flight, allowing the driver to use dedicated storage for its LXD instances alongside any use of LXD via other tools on the same servers.


OpenStack Charms

6 monthly release cycle

The OpenStack Charms project is moving to a 6 monthly release cadence (rather than the 3 month cadence we’ve followed for the last few years); This reflects the reduced rate of new features across OpenStack and the charms, and the improved process for backporting fixes to the stable charm set between releases. The next charm release will be in August, aligned with the release of OpenStack Pike and the Xenial Pike UCA.

If you have bugs that you’d like to see backported to the current stable charm set, please tag them with the ‘stable-backport’ tag (and they will pop-up in the right place in Launchpad) – you can see the current stable bug pipeline here.

Ubuntu Artful and OpenStack Pike Support

Required changes into the OpenStack Charms to support deployment of Ubuntu Artful (the current development release) and OpenStack Pike are landing into the development branches for all charms, alongside the release of Pike b1 into Artful and the Xenial-Pike UCA.

You can consume these charms (as always) via the ~openstack-charmers-next team, for example:

juju deploy cs:~openstack-charmers-next/keystone

IRC (and meetings)

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.
