Heroku San

Helpful rake tasks for Heroku.


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"


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

rake heroku:create_config

If this is a fresh project, heroku_san can create all the applications for you, and set the RACK_ENV.

rake all heroku:create heroku:rack_env


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.

Manipulate collaborators on all this project's apps (prompts for email address):

rake all heroku:share
rake all heroku:unshare

Need to add remotes for each app?

rake all heroku:remotes

A full list of tasks provided:

rake all                   # Select all Heroku apps for later command
rake console               # Opens a remote console
rake deploy[commit]        # Pushes the given commit, migrates and restarts (default: HEAD)
rake deploy:force[commit]  # Force-pushes the given commit, migrates and restarts (default: HEAD)
rake after_deploy          # Callback after deploys
rake before_deploy         # Callback before deploys
rake capture               # Captures a bundle on Heroku
rake heroku:apps           # Lists configured apps
rake heroku:create         # Creates the Heroku app
rake heroku:create_config  # Creates an example configuration file
rake heroku:gems           # Generate the Heroku gems manifest from gem dependencies
rake heroku:maintenance    # Enable maintenance mode
rake heroku:maintenance_off# Disable maintenance mode
rake heroku:push           # Pushes the given commit (default: HEAD)
rake heroku:push:force     # Force-pushes the given commit (default: HEAD)
rake heroku:remotes        # Add git remotes for all apps in this project
rake heroku:rack_env       # Add proper RACK_ENV to each application
rake heroku:rake[task]     # Runs a rake task remotely
rake heroku:share          # Adds a collaborator
rake heroku:unshare        # Removes a collaborator
rake logs                  # Shows the Heroku logs
rake migrate               # Migrates and restarts remote servers
rake restart               # Restarts remote servers

Frequently used tasks are not namespaced, everything else lives under heroku.
