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).

Add a Project to StackForge

Request a Core Group in Gerrit

StackForge uses Gerrit for group management. The first step in creating a StackForge project is to request a group in Gerrit called your-project-name-core. Members of this team will have permissions to approve code changes to your project, and to add other Gerrit users to the group.

You can request Gerrit groups by opening a bug at https://bugs.launchpad.net/openstack-ci/+filebug (make sure to mention the Gerrit name or E-mail address of at least one initial member).

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 openstack-infra/config/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 openstack-infra/config/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 openstack-infra/config/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: quantal
    tarball-site: tarballs.openstack.org

    jobs:
      - python-jobs
      - gate-{name}-pyflakes
      - gate-{name}-pylint

List of jobs included to the python-jobs jobs group is located in openstack-infra/config/modules/openstack_project/files/jenkins_job_builder/config/python-jobs.yaml.

If you aren't ready to run any gate tests 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 openstack-infra/config/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-pyflakes
      - gate-project-name-pep8
      - gate-project-name-docs
      - gate-project-name-python26
      - gate-project-name-python27
  gate:
    - gate-project-name-pep8
    - gate-project-name-pyflakes
    - gate-project-name-docs
    - gate-project-name-python26
    - gate-project-name-python27
  post:
    - project-name-coverage
    - project-name-docs
    - project-name-branch-tarball
  publish:
    - project-name-docs

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.

Configure StackForge Project to use GerritBot

To have GerritBot send Gerrit events for your project to a Freenode IRC channel edit openstack-infra/config/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/libra
      - stackforge/python-reddwarfclient
      - stackforge/reddwarf
      - 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 <<EOF
[gerrit]
host=review.openstack.org
port=29418
project=stackforge/project-name.git
EOF
git review -s
git add .gitreview
git commit -m 'Add .gitreview file.'
git review
