webmachine-ruby with Unicorn on Heroku

A very basic webmachine-ruby example app running with Unicorn/Rack on Heroku

Once the Heroku toolbelt is installed in your development environment, run the following:

$ bundle install
$ foreman start
10:14:22 web.1  | started with pid 50172
10:14:23 web.1  | I, [2013-02-01T10:14:23.144259 #50172]  INFO -- : listening on addr=0.0.0.0:5000 fd=11
10:14:23 web.1  | I, [2013-02-01T10:14:23.144360 #50172]  INFO -- : worker=0 spawning...
10:14:23 web.1  | I, [2013-02-01T10:14:23.145088 #50172]  INFO -- : master process ready
10:14:23 web.1  | I, [2013-02-01T10:14:23.145844 #50173]  INFO -- : worker=0 spawned pid=50173
10:14:23 web.1  | I, [2013-02-01T10:14:23.146181 #50173]  INFO -- : Refreshing Gem list
10:14:23 web.1  | I, [2013-02-01T10:14:23.242999 #50173]  INFO -- : worker=0 ready

You should see "hi" on localhost:5000 (or whatever port your app was started on)

To deploy to heroku:

$ heroku create
$ git push heroku master

That's it!
