Crazy Ivan (CI) is simplest possible continuous integration tool.
Create a directory where your projects will live $ mkdir /var/continuous-integration Place some project(s) in that directory $ cd /var/continuous-integration $ git clone git://github.com/edward/active_merchant.git Set up continuous integration for each project $ crazy_ivan setup # creates example ci scripts in # each project (see How this works) $ crazy_ivan setup # creates the ci directory, and # creates a configuration file, # sets a cron job to run crazy_ivan Manually run it once to check everything is ok $ cd /var/continuous-integration $ crazy_ivan /var/www/ci # the test reports path should be # accessible via your web server $ open /var/www/ci/index.html # or check it through your browser Set a cron job to run it every 15 minutes $ echo "0,15,30,45 * * * * cd /var/continuous-integration; crazy_ivan /var/www/ci" > ci.cron $ crontab ci.cron Note that you don’t want this running too frequently; having overlapping runs is possible and would be bad. (Functionality to have this run as a web-hook is planned.)
How this works
* crazy_ivan is executed periodically by cron * crazy_ivan looks in directories one level deeper than where it’s been called => asked to run in /projects /shopify looks in each /liquid of these dirs /active_merchant ========> /active_shipping => within each directory, it expects four executable scripts to execute at the /: /shopify /.ci/update version test conclusion * crazy_ivan first executes `update` and captures the output: #!/usr/bin/env bash git pull # Whatever your application # needs to do to update your # source from a repository * crazy_ivan then exectutes `version` and captures the output: #!/usr/bin/env bash #!/usr/bin/env ruby -wKU # Get a version hash/fingerprint/id puts `git show`[/^commit (.+)$/, 1] # from your version control system # # (Note that this will be truncated # to fit within a filename length.) * crazy_ivan then executes `test` and captures the output: #!/usr/bin/env bash rake db:migrate # This task prepares the application rake test # for running tests, then runs them * At each of these three steps, the output is repackaged into a .json file to be consumed in the directory holding the static html. * crazy_ivan then executes `conclusion`, passing it the same results packaged in the .json file used in the static html view.
