Capistrano Fast Deploy

A couple Capistrano tweaks to speed up deploys:

  • All changes occur in current folder, git clones directly to this folder and uses reset to deploy.
  • Symlinks in deploy:finalize_update all happen in one ssh connection
  • Rollback uses git as well

This overrides the following default capistrano tasks:

  • deploy:update_code - Uses git reset instead of the standard :scm and :deploy_viaproviders.
  • deploy:finalize_update - Concatenates all symlink commands from shared_children into a single ssh command. Also adds support for mapped_shared_children` so you can add additional symlinks like this:
set :mapped_shared_children, {
  'config/database.yml' => 'config/database.yml'
}
  • deploy:create_symlink - This is now a no-op, there are no longer individual release directories.
  • deploy:rollback, deploy:rollback:repo, deploy:rollback:cleanup - Goes back to the previous place that HEAD was pointing (HEAD@{1}). You don't want to do this if you go and monkey around with your current folder manually.
  • deploy:create_symlink - This is now a no-op, there are no longer individual release directories.

Installation

Add this line to your application's Gemfile:

gem 'capistrano-fast_deploy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-fast_deploy

Usage

Add the following to your deploy.rb:

require 'capistrano/fast_deploy'

Upgrading an existing project

It should just work automatically. deploy:update_code will "unsymlink" your current directory. After that you can safely delete your releases folder if you like.
