Capistrano Deployment Tags
This plugin to Capistrano will add timestamped and latest Git tags at each deployment, automatically. It is intended to be used with the multistage recipe and will tag each release by environment. You can, however, use it without multistage simply by setting :branch and :stage in your recipe.
What It Does
Simply: it makes it so you can track your deployments from Git. If I were to issue the command:
cap production deploy
This would result in one new git tag with the environment and timestamp:
It would also result in moving or creating this tag:
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.
capistrano-deploytags is available on rubygems.org. You can install it from there with:
gem install capistrano-deploytags
If you use Bundler, be sure to add the gem to your Gemfile.
In your Capistrano
config/deploy.rb you should add:
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.
This plugin is released under the BSD two clause license which is available in both the Ruby Gem and the source repository.
