Greetings,
The TripleO squads for CI and Tempest have just completed Sprint 12.
The following is a summary of activities during this sprint. Details
on our team structure can be found in the spec [1].
---
# Sprint 12 Epic (CI): Libvirt Reproducer
* Epic Card: https://trello.com/c/JEGLSVh6/51-reproduce-ci-jobs-with-libvirt
* Tasks: http://ow.ly/O1vZ30jTSc3
"Allow developers to reproduce a multinode CI job on a bare metal host
using libvirt"
"Enable the same workflows used in upstream CI / reproducer using
libvirt instead of OVB as the provisioning mechanism"
The CI Squad prototyped, designed, and implemented new functionality for
our CI reproducer. “Reproducers” are scripts generated by each CI job
that allow the job/test to be recreated. These are useful to both CI
team members when investigating failures, as well as developers creating
failures with the intent to iteratively debug and/or fix issues. Prior
to this sprint, the reproducer scripts supported reproduction of
upstream CI jobs using OVB, typically on RDO Cloud. This sprint we
extended this capability to support reproduction of jobs in libvirt.
This work was done for a few reasons:
* (short term) enable the team to work on upgrades and other CI team
tasks more efficiently by mitigating recurring RDO Cloud infrastructure
issues. This was the primary motivator for doing this work at this time.
* (mid-longer term) enhance / enable iterative workflows such as THT
development, debugging deployment scenarios, etc. Snapshots in
particular have proven quite useful. As we look towards a future with a
viable single-node deployment capability, libvirt has clear benefits for
common developer scenarios.
Thank you for that, a really cool feature for tripleo development!
It is expected that further iteration and refinement of this initial
implementation will be required before the tripleo-ci team is able to
support this broadly. What we’ve done works as designed. While we
welcome folks to explore, please note that we are not announcing a
supported libvirt reproducer meant for use outside the tripleo-ci team
at this time. We expect some degree of change, and have a number of
RFE’s resulting from our testing as well as documentation patches that
we’re iterating on.
That said, we think it’s really cool, works well in its current form,
and are optimistic about its future.
## We did the following (CI):
* Add support to the reproducer script [2,3] generated by CI to enable
libvirt.
* Basic snapshot create/restore [4] capability.
* Tested Scenarios: featureset 3 (UC idem), 10 (multinode containers),
37 (min OC + minor update). See sprint cards for details.
* 14-18 RFE’s identified as part of testing for future work

# Sprint 12 Epic (Tempest):
* Epic Card: https://trello.com/c/ifIYQsxs/75-sprint-12-undercloud-tempest
* Tasks: http://ow.ly/GGvc30jTSfV
“Run tempest on undercloud by using containerized and packaged tempest”
“Complete work items carried from sprint 11 or another side work going on.”
## We did the following (Tempest):
* Create tripleo-ci jobs that run containerized tempest on all stable
branches.
* Create documentation for configuring and running tempest using
containerized tempest on UC @tripleo.org <http://tripleo.org>, and blog
posts. [5,6,7]
* Run certification tests via new Jenkins job using ansible role [8]
* Refactor validate-tempest CI role for UC and containers

# Ruck and Rover
Each sprint two of the team members assume the roles of Ruck and Rover
(each for half of the sprint).
* Ruck is responsible to monitoring the CI, checking for failures,
opening bugs, participate on meetings, and this is your focal point to
any CI issues.
* Rover is responsible to work on these bugs, fix problems and the rest
of the team are focused on the sprint. For more information about our
structure, check [1]
## Ruck & Rover (Sprint 12), Etherpad [9,10]:
* Quique Llorente(quiquell)
* Gabriele Cerami (panda)
