Kumade 熊手 Build Status

Kumade is a command-line program for deploying to Heroku. It aims to provide most of what you want. Unlike other Heroku deploy gems, it is well-tested.


Development is happening very fast, and the internals are in constant flux. The public API is constant (e.g. kumade production will work), but you may have to rebase against master a couple times before your pull request can be merged.

What does Kumade do?

Before deploying, Kumade ensures the git repo is clean. After that, it packages assets using Jammit and/or More, commits them, and pushes to origin. Then it force pushes to the correct Heroku remote and runs rake db:migrate on the Heroku app.

If any step fails, it immediately prints an error and stops the deploy process.


In your Gemfile:

gem 'kumade'


kumade will deploy to any Heroku remote in the repo. For example, if you have a remote named "staging":

$ bundle exec kumade staging

To run in pretend mode, which prints what would be done without actually doing any of it:

$ bundle exec kumade staging -p

The default is to deploy to staging:

# equivalent to "bundle exec kumade staging"
$ bundle exec kumade


Kumade auto-generates a deploy:ENV task for every Heroku environment.

# in your Rakefile:
require 'kumade'

$ rake deploy:staging

If you use rake tasks, you can't pass in options (like -p/--pretend).

Does it support the Cedar stack?

Yes. Kumade will automatically detect if your app is running on Cedar.


Tested against:

  • MRI 1.8.7
  • MRI 1.9.2
  • REE 1.8.7

Miscellaneous Features

Want to run a task before bundling your assets on deploy? In your Rails app's rake tasks, drop in:

namespace :kumade do
  task :before_asset_compilation do
    puts "This runs before assets are committed and pushed to the remote"

You can hook in any custom code you want to run there before deploying!

What's with the name?

Kumade (pronunciation here) means "bamboo rake" in Japanese.
