I am trying to deploy a basic JRuby on Rails app to EC2 using Rubber. I am following this guide and the only difference is that I'm using JRuby.
Is this possible? Can I use one of the provided templates (for example complete_passenger_postgresql) with JRuby?
I see that the rubber-ruby.yml file has a line where you can specify the ruby_version. Do I need to specify that I want to use JRuby?
Is there a different template that I should be using?
At the moment I am getting the following error when I try the command 'cap rubber:create_staging'
