A simple capistrano setup that Auto-creates git tags on deploy, and supports multiple deployment environments

capistrano_create_git_tags.rb

task :production do
  # :deployment variable should match task name
  set :deployment, 'production'
  set :deploy_to, "/home/user/www/#{application}"
  set :branch, "master"
  find_and_execute_task("deploy:tags:schedule_creation")
end

task :staging do
  # :deployment variable should match task name
  set :deployment, 'staging'
  set :deploy_to, "/home/user/www/staging/#{application}"
  set :branch, "master"
  find_and_execute_task("deploy:tags:schedule_creation")
end

namespace :deploy do
	namespace :tags do
		task :schedule_creation do
			after "deploy", "deploy:tags:create"
		end
		
		task :skip do
			set :skip_tag_creation, true
		end
		
		desc "Automatically create a git tag in the form 'deploy_yyyy_mm_dd_hh_mm'"
		task :create do
			if self[:skip_tag_creation]
				logger.info("skipping tag creation") 
			else
				tag_name = Time.now.strftime("deploy_%Y_%m_%d_%H_%M")
				
				system "git tag -a -m 'Deployment on #{deployment}' #{tag_name}"
				
				system "git push origin #{tag_name}"
				if $? != 0
					raise "Pushing tag to origin failed"
				end
			end
		end
	end
end

Hey! thanks for such a piece of code! I've used it to build http://github.com/Zorros/zorros-deploy
