Ruby and Rails Packaging to Production
This document discusses packaging Ruby and Rails applications for production. It covers using system packages versus gems, configuration management tools like Chef and Puppet, creating Debian packages, packaging gems, build servers, pain points like outdated Rubygems packages, and ideas for deeper Bundler integration and packaging gems by default. Overall it presents strategies for deploying Ruby applications as system packages for production servers.

- #54 \n
- #55 tools\nnot usual to &#x201C;build&#x201D; stuff on production servers\nplatforms offer easy ways to make binary/system packages\nruby is probably missing that. Nobody is caring\n

- #64 cloud IaaS and VMs help a lot\nbricklayer\nlaunchpad\nCI servers (hudson, bamboo, teamcity, ...)\n\n
- #65 - Watch git repositories\n- Build snapshots for each commit\n- Watch for tags testing_1.2.3 and stable_1.2.3\n- Promote packages to a ftp server (which runs reprepro or any other debian repository tool)\n- Has a rest API\n- Has cocoa-like web interface wrote with cappuccino framework\n- Batteries are included except redis server\n\n\n

- #67 - Lauchpad generate binaries out of your source as long as your application is already ready to be packaged\n- Build packages for multiple archs\n- Host the package in a repository called PPA\n- Developed and open source by canonical\n
