We have setup an instance in labs that ships with Gerrit/Zuul and has its job defined in Jenkins Job Builder. It can be used as a playground area to test changes we are not confident enough in deploying straight to production.
We have a bunch of instances in the wmflabs integration project. The instances in the integration project have their own puppet master on integration-puppetmaster01.integration.eqiad.wmflabs.
Puppet manifests are applied to install Gerrit, Jenkins and Zuul with appropriate settings.
Note: Gerrit is installed via the Debian package unlike production which is using a custom war.
A web proxy is setup in front of the instance. The URL entry points are:
Gerrit is set to development mode so anyone can log in as any user.
To login :
- browse to http://gerrit-test.wmflabs.org/gerrit
- Click Sign In at the top right (it may be Become depending on the gerrit UI you use)
- Click on a name or number
You should now be logged in.
- Head to your settings at http://gerrit-test.wmflabs.org/gerrit/#/settings/ and add a custom ssh public key.
Gotcha: you will probably need to be added to a Gerrit group. The full list of admins is at http://gerrit-test.wmflabs.org/gerrit/#/admin/groups/1,members
Cloning repo and URL Edit
The repositories are available using http://gerrit-test.wmflabs.org/gerrit
Full list of projects: http://gerrit-test.wmflabs.org/gerrit/#/admin/projects/
git clone http://gerrit-test.wmflabs.org/gerrit/mediawiki/core git clone http://gerrit-test.wmflabs.org/gerrit/mediawiki/core/vendor git clone http://gerrit-test.wmflabs.org/gerrit/mediawiki/extensions/FirstExtension git clone http://gerrit-test.wmflabs.org/gerrit/mediawiki/extensions/SecondExtension
They are not the real repositories but dummy ones meant for testing. The
.gitreview files might be correct.
Create an account in Jenkins http://http://gerrit-jenkins.wmflabs.org/signup with a unique password and a valid email address. Then you will have to ask to be granted write access on the instance. A list of users is at http://http://gerrit-jenkins.wmflabs.org/asynchPeople/ or you can ping hashar.
Creating jobs Edit
Simply create a new JJB ini file as detailed on CI/JJB.
The jobs are very simple.
Note we might be missing some plugins on the labs instance.
Zuul is configured via the puppet class
We run a different version than the one in production which is in integration/zuul.git in the labs branch. It has a few specific commits which are force pushed by hashar from time to time. You probably do not want to mess with it.
To have any idea of the commit difference you can:
git clone ssh://gerrit.wikimedia.org:29418/integration/zuul.git cd zuul git log origin/master...wikimedia/labs
The triple dot find the common ancestor.
Just like in production, Zuul logs are in
