A couple of guys from Heroku gave a talk tonight at DC Python and it looked like a good solution for running small sites. However, I was disappointed that set up was more difficult on Ubuntu 10.04 than turn key installers on Windows and Mac OS X. The set up instructions required a few modifications to work properly.
sudo apt-add-repository 'deb http://toolbelt.herokuapp.com/ubuntu ./'
curl https://toolbelt.herokuapp.com/apt/release.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install heroku-toolbelt
sudo apt-get install ruby libopenssl-ruby ruby1.8-dev
sudo apt-get install libreadline-ruby
Type "heroku" at the command line to check that the installation is working properly.
