Heroku San

Helpful rake tasks for Heroku.

Build Status Code Climate Gemnasium


Rails 3+

Add this to your Gemfile:

  group :development do
    gem 'heroku_san'

Rails 2

To install add the following to config/environment.rb:

  config.gem 'heroku_san'

Rake tasks are not automatically loaded from gems, so you’ll need to add the following to your Rakefile:

    require 'heroku_san/tasks'
  rescue LoadError
    STDERR.puts "Run `rake gems:install` to install heroku_san"


Update your Gemfile:

  group :development do
    gem 'heroku_san'

Update your Rakefile:

  require "bundler/setup"
    require "heroku_san"
    config_file = File.join(File.expand_path(File.dirname(__FILE__)), 'config', 'heroku.yml')
    HerokuSan.project =, :deploy => HerokuSan::Deploy::Sinatra)
    load "heroku_san/tasks.rb"
  rescue LoadError
    # The gem shouldn't be installed in a production environment


In config/heroku.yml you will need to add the Heroku apps that you would like to attach to this project. You can generate this file by running:

Rails 3+

  rails generate heroku_san

Everything else

  rake heroku:create_config

Customize the file for your project. If this is a fresh project, heroku_san can create all the applications for you, and set each one's RACK_ENV.

  rake all heroku:create heroku:rack_env

Configure your Heroku apps according to config/heroku.yml by running:

  rake all heroku:config


After configuring your Heroku apps you can use rake tasks to control the apps.

  rake production deploy

A rake task with the shorthand name of each app is now available and adds that server to the list that subsequent commands will execute on. Because this list is additive, you can easily select which servers to run a command on.

  rake demo staging restart

A special rake task 'all' is created that causes any further commands to execute on all Heroku apps.

  rake all restart

Need to add remotes for each app?

rake all heroku:remotes

A full list of tasks provided:

  rake heroku:addons                # Install addons for the application.
  rake heroku:addons:local          # List configured addons, without installing them
  rake heroku:apps                  # Lists configured apps
  rake heroku:apps:local            # Lists configured apps without hitting heroku
  rake heroku:config                # Add config:vars to each application.
  rake heroku:config:list           # Lists config variables as set on Heroku
  rake heroku:config:list:local     # Lists local config variables without setting them
  rake heroku:config:rack_env       # Add proper RACK_ENV to each application

  rake heroku:rake[task]            # Runs a rake task remotely
  rake heroku:remotes               # Add git remotes for all apps in this project
  rake heroku:restart               # Restarts remote servers
  rake heroku:shell                 # Opens a bash shell within app
  rake heroku:stage:all             # Select all Heroku apps for later command
