Custom Rake Tasks

You can create Custom Rake Tasks to automate frequently used commands. As an example, add the following into lib/tasks/fly.rake to reduce the number of keystrokes it takes to launch a console:

namespace :fly do
  task :ssh do
    sh 'fly ssh console'
  end

  task :console do
    sh 'fly ssh console -C "app/bin/rails console"'
  end

  task :dbconsole do
    sh 'fly ssh console -C "app/bin/rails dbconsole"'
  end
end

You can run these tasks with bin/rails fly:ssh, bin/rails fly:console, and bin/rails fly:dbconsole respectively.
