I just went through this dance last week :) Check out: http://docs.heroku.com/constraints#git-submodules
Also here's the quick and easy way to install extensions that play well w/ Heroku: $ git clone git://github.com/saturnflyer/radiant-vhost-extension.git vendor/extensions/vhost and optionally/when available: $ rake radiant:extensions:<extension_name>:update $ rake radiant:extensions:<extension_name>:install then push to Heroku! $ git push heroku master $ heroku db:push Hope that helps!
