I tried following the instructions here in order to create a static website on Heroku’s Cedar stack.

I have put the site up here.

When I try to push the app (using “git push heroku master”), I get the following error:

Kushs-MacBook-Air:hgtr kushpatel$ git push heroku master
Counting objects: 7, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (7/7), done.
Writing objects: 100% (7/7), 1.29 KiB, done.
Total 7 (delta 1), reused 0 (delta 0)

-----> Heroku receiving push
-----> Removing .DS_Store files
 !     Heroku push rejected, no Cedar-supported app detected

To git@heroku.com:gentle-warrior-1301.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:gentle-warrior-1301.git'

Any help is greatly appreciated. I am on the latest ruby/rack/heroku

    The instructions are for Bamboo stack which would have had Rack installed – the Cedar stack is entirely empty so you need to have rack installed.

    You need to add a Gemfile with

    source :rubygems

gem 'rack'

    bundle it and then add the Gemfile and Gemfile.lock to git and repush.
