CI Joe
Joe is a Continuous Integration server that'll run your tests on demand and report their pass/fail status.
Because knowing is half the battle.
Quickstart
RubyGems:
$ gem install cijoe
$ git clone git://github.com/you/yourrepo.git
$ cijoe yourrepo
Boom. Navigate to http://localhost:4567 to see Joe in action.
Check cijoe -h for other options.
Basically you need to run cijoe and hand it the path to a git
repo. Make sure this isn't a shared repo: Joe needs to own it.
Joe looks for various git config settings in the repo you hand it. For
instance, you can tell Joe what command to run by setting
cijoe.runner:
$ git config --add cijoe.runner "rake -s test:units"
Joe doesn't care about Ruby, Python, or whatever. As long as the runner returns a non-zero exit status on fail and a zero on success, everyone is happy.
Need to do some massaging of your repo before the tests run, like
maybe swapping in a new database.yml? No problem - Joe will try to
run .git/hooks/after-reset if it exists before each build phase.
Do it in there. Just make sure it's executable.
Want to notify IRC or email on test pass or failure? Joe will run
.git/hooks/build-failed or .git/hooks/build-worked if they exist
and are executable on build pass / fail. They're just shell scripts -
put whatever you want in there.
Tip: your repo's HEAD will point to the commit used to run the
build. Pull any metadata you want out of that scro.
** WARNING ** Do not run this against a git repo that has unpushed commits, as this will do a hard reset against the github remote and wipe out unpushed changes.
Other Branches
Want joe to run against a branch other than master? No problem:
$ git config --add cijoe.branch deploy
Queueing
Joe runs just one build at the time. If you expect concurrent push's to your repo and want joe to build each in a kind of queue, just set:
$ git config --add cijoe.buildqueue true
Joe will save requests while another build runs. If more than one push hits joe, he just picks the last after finishing the prior.
Campfire
Campfire notification is included, because it's what we use. Want Joe
notify your Campfire? Put this in your repo's .git/config:
[campfire]
token = abcd1234
subdomain = whatever
room = Awesomeness
ssl = false
Or do it the old fashion way:
$ cd yourrepo
$ git config --add campfire.token abcd1234
$ git config --add campfire.subdomain github
etc.
Checkin' Status
Want to see how your build's doing without any of this fancy UI crap? Ping Joe for the lowdown:
curl http://localhost:4567/ping
Joe will return 200 OK if all is quiet on the Western Front. If
Joe's busy building or your last build failed, you'll get 412 PRECONDITION FAILED.
Multiple Projects
Want CI for multiple projects? Just start multiple instances of Joe!
He can run on any port - try cijoe -h for more options.
If you're using Passenger, see this blog post.
HTTP Auth
Worried about people triggering your builds? Setup HTTP auth:
$ git config --add cijoe.user chris
$ git config --add cijoe.pass secret
GitHub Integration
Any POST to Joe will trigger a build. If you are hiding Joe behind HTTP auth, that's okay - GitHub knows how to authenticate properly.
You can find the Post-Receive option under the 'Service Hooks' subtab of your project's "Admin" tab.
Daemonize
Want to run Joe as a daemon? Use nohup:
$ nohup cijoe -p 4444 repo &
