Currently the way to deploy your application in cloudbees @RUN was trough the cloudbees sdk or a maven plugin.
Now you will be able to do it with a Jenkins Plugin configured in your Jenkins job.
Currently it's not yet released but a build version is available here.
Have a look at this movie. Note it's a huge movie with some suspens : so take a pop corn box and be patient :-).
Sources are available here : https://github.com/olamy/cloudbees-deployer-plugin.
The plugin uses the cloudbess client api available here : https://github.com/cloudbees/cloudbees-api-client
Feel free to test it and report any issues or new features you'd like to see.
Thanks to cloudbees for the sponsorship of this developpement.
Have Fun and onward ! :-)
