This plugin to Capistrano will add tags for each deployment that you make to the project. It is intnded to be used with the multistage plugin and will tag each release by environment. Each successful deployment will result in a new tag as well as moving an existing tag that points to the last deployment.

What It Does

If I were to issue the command:

cap production deploy

This would result in one new git tag with the environment and timestamp:

production-2012.04.02-203155

It would also result in moving or creating this tag:

production-latest

These tags can be used for any number of useful things including generating statistics about deployments per day/week/year, tracking code size over a period of time, detecting Rails migrations, and probably a thousand other things I haven't thought of.

Usage

If you use Bundler, be sure to add the gem to your Gemfile. In your Capistrano config/deploy.rb you should add:

require 'capistrano_deploytags'

This will create two tasks, one that runs before deployment and one that runs after.

NOTE: You will be creating and pushing tags from the version of the code in the current checkout. This plugin needs to be run from a clean checkout of your codebase. You should be deploying from a clean checkout anyway, so in most cases this is not a restriction on how you already do things. The plugin will check if your code is clean and complain if it is not.
