Agenda
● Objectives of the project
● Where we are
● What remains to be done
● Discussions

4. RPM Factory for RDO - 29 Jan 20164
Objectives of RPM Factory for RDO
● Ease the learning curve to contribute to RDO by using the same
workflow as OpenStack
● Locate the different components used in the infra at the same
location as much as possible

5. RPM Factory for RDO - 29 Jan 20165
Objectives: more details
● gerrit workflow for packaging with a gating approach
● consumable RPM packages for testing upstream projects in a continuous
way:
○ prepare next RDO release
○ needed artifacts for RDO manager and Puppet modules testing
● have a set of validated packages ready for consumption at different
readiness levels: installable, smoke test CI, tripleo-CI, puppet CI…

Where we are
6
We are experimenting this workflow using the Software Factory project
at http://rpmfactory.beta.rdoproject.org
Software Factory is an integration of the OpenStack workflow to be used
on your premise http://softwarefactory-project.io/:
● gerrit, zuul, jenkins, nodepool
with some add-ons:
● self-configurable using the config git repo with yaml files
● etherpad, paste, a config REST API, a SSO and a dashboard

Where we are
8
We are building a gerrit workflow for rpm package building:
● run unit tests from upstream project
● 2 git repositories way of working
● package builds in koji
● integration with Delorean
● gating of packages before creating a public repository using
functional tests

9. RPM Factory for RDO - 29 Jan 2016
Where we are
9
Gerrit and Zuul Pipelines
2 git repositories per package:
1. project repository
a. check pipeline: tox checks like upstream OpenStack.
b. non merged review series to manage patch series. Avoid push -f and
so allow to keep the history.
2. dist-git repository
a. check and gate pipelines to build packages on the stable branches:
i. using koji and validated using functional tests.
b. check pipeline delorean build on the rpm-master branch.

10. RPM Factory for RDO - 29 Jan 201610
What remains to be done
● import all the repositories (1 package remains to be done)
● finish connection between delorean and gerrit
● write documentation
● finalize change to rdopkg to import the gerrit branch series
● automate branch creation

11. RPM Factory for RDO - 29 Jan 201611
Conclusion
● gating rpm packages can be done!
● we need more feedback!
