One Click Deployment with Jenkins - PHP Unconference 2011

The document discusses one click deployment with Jenkins. It describes setting up a Jenkins build server to run continuous integration and deployment for PHP projects. The build server runs tests with PHPUnit and checks code quality with tools like PHPMD on every commit. Successful builds trigger deployment to staging and production servers, allowing developers to deploy fixes and changes with a single click in minutes.
