:title: StackForge StackForge ########## StackForge is the way that OpenStack related projects can consume and make use of the OpenStack project infrastructure. This includes Gerrit code review, Jenkins continuous integration, GitHub repository mirroring, and various small things like IRC bots, pypi uploads, RTFD updates. Projects should make use of StackForge if they want to run their project with Gerrit code review and have a trunk gated by Jenkins. StackForge projects are expected to be self sufficient when it comes to configuring Gerrit/Jenkins/Zuul etc. The openstack-infra team can provide assistance as resources allow, but should not be relied on. What StackForge is not: * Official endorsement of a project by OpenStack. * Access to a GitHub organization (StackForge projects are mirrored to GitHub, this is all the GitHub org is used for). * A guarantee of eventual OpenStack incubation (Though it is a good first step in that process as it exposes the project to the OpenStack way of doing things). Audience ******** The focus of StackForge is to provide a place for OpenStack contributors to maintain related unofficial projects using the same tools and procedures as they employ when working on official OpenStack projects, to make it easier for other OpenStack developers to contribute effort to those projects and in some cases to ease a project's path to incubation and official integration. As such, the target audience for this document is current OpenStack developers who are assumed to already be familiar with how changes are uploaded and reviewed within OpenStack projects. As an introduction to OpenStack contribution, it is recommend to first read https://wiki.openstack.org/wiki/How_To_Contribute and in particular the https://wiki.openstack.org/wiki/Gerrit_Workflow article linked from it. Add a Project to StackForge *************************** Create a new StackForge Project with Puppet =========================================== OpenStack uses Puppet and a management script to create Gerrit projects with simple changes to the openstack-infra/config repository. To start make sure you have cloned the openstack-infra/config repository ``git clone https://github.com/openstack-infra/config``. First you need to add your StackForge project to the master project list. Edit ``modules/openstack_project/templates/review.projects.yaml.erb`` and add a new section for your project at the end of the file. It should look something like:: - project: stackforge/project-name description: Latest and greatest cloud stuff. upstream: git://github.com/awesumsauce/project-name.git The description will set the project description on the GitHub StackForge mirror, and the upstream should point at an existing repository which can be used to preseed Gerrit with an initial commit history. Both of these are optional. Note that the current tools assume that the upstream repo will have a master branch. The next step is to add a Gerrit ACL config file. Edit ``modules/openstack_project/files/gerrit/acls/stackforge/project-name.config`` and make it look like:: [access "refs/heads/*"] label-Code-Review = -2..+2 group project-name-core label-Approved = +0..+1 group project-name-core workInProgress = group project-name-core [access "refs/tags/*"] create = group project-name-core pushTag = group project-name-core [receive] requireChangeId = true requireContributorAgreement = true [submit] mergeContent = true The access sections in the example ACL grant the project's core group approval privileges and the ability so set/un-set WIP status on changes, as well as the ability to push tags. The other sections set some required options for Gerrit to function normally (enforcing presence of a Change-Id in commits and allowing changes to be merged). This example also expects contributors to agree to a standard OpenStack CLA, join the OpenStack Foundation and submit contact information (this feature can be disabled by setting requireContributorAgreement to false). That is all that is necessary to add a StackForge project to Gerrit; however, this project isn't very useful until we setup Jenkins jobs for it and configure Zuul to run those jobs. Continue reading to configure these additional tools. Add Jenkins Jobs to StackForge Projects ======================================= In the same openstack-infra/config repository (and in the same change if you like) we need to edit additional files to setup Jenkins jobs and Zuul for the new StackForge project. If you are interested in using the standard python Jenkins jobs (docs, pep8, python 2.6 and 2.7 unittests, and coverage), edit ``modules/openstack_project/files/jenkins_job_builder/config/projects.yaml`` and add a new section for your project at the end of the file. It should look something like:: - project: name: project-name github-org: stackforge node: precise tarball-site: tarballs.openstack.org jobs: - python-jobs List of jobs included to the ``python-jobs`` jobs group is located in ``modules/openstack_project/files/jenkins_job_builder/config/python-jobs.yaml``. For document publication there's also a publisher job template for the popular `Read the Docs`_ documentation hosting service, which can be used by specifying the ``rtfd-id`` for the project (obtained from your readthedocs.org account) and then adding the ``hook-{name}-rtfd`` template to the jobs list:: - project: name: project-name github-org: stackforge node: precise rtfd-id: 7095 tarball-site: tarballs.openstack.org jobs: - python-jobs - hook-{name}-rtfd .. _Read the Docs: https://readthedocs.org/ If you aren't ready to run any gate tests or other project-specific jobs yet, you don't need to edit ``projects.yaml``. Now that we have Jenkins jobs we need to tell Zuul to run them when appropriate. Edit ``modules/openstack_project/files/zuul/layout.yaml`` and add a new section for your project at the end of the file. It should look something like:: - name: stackforge/project-name check: - gate-project-name-docs - gate-project-name-pep8 - gate-project-name-python26 - gate-project-name-python27 gate: - gate-project-name-docs - gate-project-name-pep8 - gate-project-name-python26 - gate-project-name-python27 post: - project-name-branch-tarball - project-name-coverage - hook-project-name-rtfd If you aren't ready to run any gate tests yet and did not configure python-jobs in project.yaml, it should look like this instead:: - name: stackforge/project-name check: - gate-noop gate: - gate-noop That concludes the bare minimum openstack-infra/config changes necessary to add a project to StackForge. You can commit these changes and submit them to review.openstack.org at this point, or you can wait a little longer and add your project to GerritBot first. Request an Initial Gerrit Core Group Member =========================================== StackForge uses Gerrit for group management. After the change to create your StackForge project has merged, request an initial member for the Gerrit group configured in your ACL (probably something like ``your-project-name-core``). Members of this team will have permissions to approve code changes to your project as defined in your ACL, and to add other Gerrit users to the group. You can request an initial Gerrit group member by opening a bug at https://bugs.launchpad.net/openstack-ci/+filebug (make sure to mention the Gerrit full name or E-mail address of your initial member). See https://wiki.openstack.org/wiki/Project_Group_Management for details on project group management. Configure StackForge Project to use GerritBot ============================================= To have GerritBot send Gerrit events for your project to a Freenode IRC channel edit ``modules/gerritbot/files/gerritbot_channel_config.yaml``. If you want to configure GerritBot to leave alerts in a channel GerritBot has always joined just add your project to the project list for that channel:: stackforge-dev: events: - patchset-created - change-merged - x-vrif-minus-2 projects: - stackforge/foo - stackforge/python-fooclient - stackforge/project-name branches: - master If you want to join GerritBot to a new channel add a new section to the end of this file that looks like:: project-name-dev: events: - patchset-created - change-merged - x-vrif-minus-2 projects: - stackforge/project-name branches: - master And thats it. At this point you will want to submit these edits as a change to review.openstack.org. Add .gitreview file to project ============================== If the new project you have added has a specified upstream you will need to add a ``.gitreview`` file to the project once it has been created. This new file will allow you to use ``git review``. The basic process is clone from stackforge, add file, push to Gerrit, review and approve.:: git clone https://github.com/stackforge/project-name cd project-name git checkout -b add-gitreview cat > .gitreview <
