Graduating to Jenkins CI for Ruby(-on-Rails) Teams
7 likes6,205 views
The document summarizes a presentation given at the 2011 Jenkins User Conference in New York City about using Jenkins for continuous integration for Ruby on Rails projects. It discusses setting up Jenkins on low-cost virtual servers, configuring jobs for development builds, deployments, and cron jobs, and using plugins to integrate with version control systems and automate tasks. It also promotes the Jenkins client Ruby gem for programmatically controlling Jenkins.
