We are moving away from a Java based infrastructure to writing applications in Ruby on Rails. An important part of our former infrastructure was the ability to automatically deploy our software via the continuous integration server via a series of Ant tasks so we have been looking for a good way to do the same sort of thing with Rails code.
The established choice for Rails automated deployment seems to be Capistrano however there have been complaints about its speed and there seems to be a shift towards Mina which behaves differently under the hood.
Our intended development roadmap has us building a large number of small Rails projects all of which will need very similar deployment scripts so we also need a sensible way to manage the distribution of those scripts. We wrapped them in a gem which could simply be added to the project Gemfile and added a helper script which can set up a project and generate deployment new environments as needed.
We have made the gem public on our team github account with some instructions for use in the README and will be pushing updates as we add features and fix problems. If you find it useful, please let us know!
