Ubuntu OpenStack Dev Summary – 12th June 2017

devsumWelcome to the second 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

The current set of OpenStack Newton point releases have been released:

https://bugs.launchpad.net/cloud-archive/+bug/1688557

The next cadence cycle of stable fixes is underway – the current candidate list includes:

Cinder: RBD calls block entire process (Kilo)
https://bugs.launchpad.net/cinder/+bug/1401335

Cinder: Upload to image does not copy os_type property (Kilo)
https://bugs.launchpad.net/ubuntu/+source/cinder/+bug/1692446

Swift: swift-storage processes die of rsyslog is restarted (Kilo, Mitaka)
https://bugs.launchpad.net/ubuntu/trusty/+source/swift/+bug/1683076

Neutron: Router HA creation race (Mitaka, Newton)
https://bugs.launchpad.net/neutron/+bug/1662804

We’ll also sweep up any new stable point releases across OpenStack Mitaka, Newton and Ocata projects at the same time:

https://bugs.launchpad.net/ubuntu/+bug/1696177

https://bugs.launchpad.net/ubuntu/+bug/1696133

https://bugs.launchpad.net/ubuntu/+bug/1696139

Development Release

x86_64, ppc64el and s390x builds of Ceph 12.0.3 (the current Luminous development release) are available for testing via PPA whilst misc build issues are resolved with i386 and armhf architectures:

https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2779

OpenStack Pike b2 was out last week; dependency updates have been uploaded (including 5 new packages) and core project updates are being prepared this week pending processing of new packages in Ubuntu Artful development. .


OpenStack Snaps

We’re really close to a functional all-in-one OpenStack cloud using the OpenStack snaps – work is underway on the nova-hypervisor snap to resolve some issues with use of sudo by the nova-compute and neutron-openvswitch daemons. Once this work has landed expect a more full update on efforts to-date on the OpenStack snaps, and how you can help out with snapping the rest of the OpenStack ecosystem!

If you want to give the current snaps a spin to see what’s possible checkout snap-test.


Nova LXD

Work on support for new LXD features to allow multiple storage backends has been landed into nova-lxd. Support for LXD using storage pools has also been added to the nova-compute and lxd charms.

The Tempest experimental gate is now functional again (hint: use ‘check experimental’ on a Gerrit review). Work is also underway to resolve issues with Neutron linuxbridge compatibility in OpenStack Pike (raised by the OpenStack-Ansible team – thanks!), including adding a new functional gate check for this particular networking option.


OpenStack Charms

Deployment Guide

The charms team will be starting work on the new OpenStack Charms deployment guide in the next week or so; if you’re an OpenStack Charm user and would like to help contribute to a best practice guide to cover all aspects of building an OpenStack cloud using MAAS, Juju and the OpenStack Charms we want to hear from you!  Ping jamespage in #openstack-charms on Freenode IRC or attend our weekly meeting to find out more.

Stable bug backports

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 pipeline here.

We’ve had a flurry of stable backports of the last few weeks to fill in the release gap left when the project switched to a 6 month release cadence so be sure to update and test out the latest versions of the OpenStack charms in the charm store.

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.

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

Stable Releases

Ceph 10.2.7 for Xenial, Yakkety, Zesty and Trusty-Mitaka UCA:
https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1684527

Open vSwitch updates (2.5.2 and 2.6.1) for Xenial and Yakkety plus associated UCA pockets:
https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1673063
https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1641956

Point releases for Horizon (9.1.2) and Keystone (9.3.0) for Xenial and Trusty-Mitaka UCA:
https://bugs.launchpad.net/ubuntu/+source/keystone/+bug/1680098

And the current set of OpenStack Newton point releases have just entered testing:
https://bugs.launchpad.net/cloud-archive/+bug/1688557

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.

snap install openstackclients

Over the last month or so I’ve been working on producing snap packages for a variety of OpenStack components.  Snaps provide a new fully isolated, cross-distribution packaging paradigm which in the case of Python is much more aligned to how Python projects manage their dependencies.

Alongside work on Nova, Neutron, Glance and Keystone snaps (which I’ll blog about later), we’ve also published snaps for end-user tools such as the OpenStack clients, Tempest and Rally.

If you’re running on Ubuntu 16.04 its really simple to install and use the openstackclients snap:

sudo snap install --edge --classic openstackclients

right now, you’ll also need to enable snap command aliases for all of the clients the snap provides:

ls -1 /snap/bin/openstackclients.* | cut -f 2 -d . | xargs sudo snap alias openstackclients

after doing this, you’ll have all of the client tools aligned to the OpenStack Newton release available for use on your install:

aodh
barbican
ceilometer
cinder
cloudkitty
designate
freezer
glance
heat
ironic
magnum
manila
mistral
monasca
murano
neutron
nova
openstack
sahara
senlin
swift
tacker
trove
vitrage
watcher

The snap is currently aligned to the Newton OpenStack release; the intent is to publish snaps aligned to each OpenStack release using the series support that’s planned for snaps –  so you’ll be able to pick clients appropriate for any supported OpenStack release or for the current development release.

You can check out the source for the snap on github; writing a snap package for a Python project is pretty simple, as it makes use of the standard pip tooling to describe dependencies and install Python modules. Kudos to the snapcraft team who have done a great job on the Python plugin.

Let us know what you think by reporting bugs or by dropping into #openstack-snaps on Freenode IRC!
