Managing and deploying a Rails application can be enough drive anyone to drink. There is an entire world of knowledge and skills to master. There are eleventy different decisions to fathom and make. And even when you have learned those skills and made those decisions, there are many tedious and error-prone steps to perform just to get a server in working condition. But it does not have to be this way. Moonshine, an open source marriage of Capistrano and Puppet, allows you to forget your deployment troubles. Moonshine encapsulates knowledge for building and managing servers, has opinions about the decisions you need to make, and automates the pain and tedium of manual configuration away. In short, you can enjoy a drink at your leisure, instead of being driven to it. This presentation will inform users of all levels about the complexities of deployment along with solutions that work.
