Tool Overview
• Gerrit
• Git-Review
• JIRA
• Jenkins
• Mailman
• Confluence
• IRC
• MeetBot
• Etherpad
• Bitergia

Gerrit
• Web based code review and git repository
• Hosts all the OPNFV code repositories
• Interfaces with JIRA and Jenkins

Git-Review
• Git plugin created by OpenStack for working
with Gerrit
• Replaces
– git push origin HEAD:refs/for/master
with
– git review
• Makes downloading patchsets easy

Git-Review: Example
• git review -s
Initial repo setup that adds a git remote called
gerrit and installs a commit-hook. Requires
.gitreview file.
• git review -d <change>,<patch>
Downloads the change to a new branch. No
messing with FETCH_HEAD.

Gerrit/Git-Review Demo
• Prerecorded
– Clone Repository
– Download Patchset
– Add Reviewer

JIRA
• Issue/Bug Tracker
• Can have associated Gerrit change
• Keep project on track with milestones

Jenkins
• Automated building and testing of OPNFV
• Reports build and test results back to Gerrit
• Gatekeeper for merging commits
• Jobs are in source controlled and deployed
with Jenkins Job Builder

Sandbox Locations

Mailman
• Mailing list software
• Majority of discussions and announcement
• Tags used for individual projects

Confluence
• Wiki and information store
• Used for project proposals, process
documentation, and release planning

IRC
• Real time chat protocol
• Messages are only conveyed to chat
participants

MeetBot
• IRC bot for taking meeting notes
• Automatically saves notes for public viewing
at end of meeting

Etherpad
• Collaborative wiki
• Short lived documents, notes, and plans

Bitergia
• Project and tool statistics and reports
• Custom OPNFV ELK dashboard

OPNFV Release Overview
• 6 month cadence for major releases
• 2 minor releases follow at approximately 6 and 12 weeks after
the major release
– The minor releases allow for bug fixes and additional content
that was not ready as of the initial release
• Release artifacts consist of ISOs and RPMs for each supported
installer
– Except Joid which is installed via git clone
• Documentation is published via read-the-docs

OPNFV Projects and Scenarios
• OPNFV feature projects are deployed and tested via “scenario”
• An OPNFV “scenario” is defined as:
– An installer. Currently:
• Apex
• Compass
• Fuel
• Joid
– A set of components. Typically:
• OpenStack
• An SDN controller
• One or more features
– A configuration

Milestone Overview
• Milestones 0 & 1 - Intent-to-Participate Window
– OPNFV projects, previously approved by the TSC, must
express their intent-to-participate between MS0 and MS1.
– In addition, projects must also complete and publish their
release plans by MS1.
• Milestone 2 - Test Case Documentation
– Projects are required to have their test cases documented in
the test case database

Milestone Overview
• Milestone 3 - Installer / OpenStack Integration
– Designed to establish foundation for feature project
development.
– Most critical milestone. Direct impact on feature
development and stabilization
Upstream Components
(OpenStack, ODL, etc.)

Milestone Overview
• Milestone 3 - Installer / OpenStack Integration (continued)
– This milestone may be deconstructed into multiple,
interdependent steps as follows
– Phase 0 -
• Installer / Openstack integration
• Functest / Openstack integration sufficient to support
health check
– Phase 1 (+ 3 weeks)
• Installers pass health check (nosdn)
– Phase 2 (+ 3 weeks)
• Installer + SDN controller passes health check

Milestone Overview
• Milestone 4 - Infrastructure Updates Completed
– Functest supports health check + smoke test
– AKA - test framework complete
– At this point we hope to be able to support feature development and
automated test in a stable environment
• Milestone 5 - Scenario integration
– All feature projects have completed integration with scenarios
• i.e., feature is deployed with a set of components, using a specific
installer, with a designated configuration

Milestone Overview
• Milestone 6 - test case implementation; preliminary
documentation; stable branch window opens
– Test cases documented in MS2 must be implemented
at this point
– Preliminary documentation requirement recently added
to reduce flailing at the end of the release period
• Directory structure
• Placeholder documents
– Stable branch window opens
• Milestone 7 - stable branch window closes

Milestone Overview
• Milestone 8 - Formal test execution completed
• Milestone 9 - JIRA bookkeeping updated
• Milestone 10 - Documentation completed
• Milestone 11 - Release
