Question

I have one ‘super’ repository in GitHub which will contain several applications I would like to deploy to Heroku. Here is an example of my repository.

/app
  /.git
  /website <-- would like to deploy this to Heroku

When I try to push using the following command:

$ git push heroku master

I get the following error:

Heroku push rejected, no Rails or Rack app detected.

How do I deploy a subdirectory to Heroku?

Answer 1

This can be accomplished by putting a config.ru in your root directory that tells Heroku where to find your app. For example, with Rails 3, try a config.ru like this in your root directory:

WEBSITE_SUBDIR = 'website'
require "#{WEBSITE_SUBDIR}/config/environment"
run YourApplicationName::Application

And on Rails 2.x, you’ll need something like this:

WEBSITE_SUBDIR = 'website'
require "#{WEBSITE_SUBDIR}/config/environment"
use Rails::Rack::LogTailer
use Rails::Rack::Static
run ActionController::Dispatcher.new
