Capistrano task to ask confirmation before deploying to production

gistfile1.rb

task :ask_production_confirmation do
  set(:confirmed) do
    puts <<-WARN

    ========================================================================

      WARNING: You're about to perform actions on production server(s)
      Please confirm that all your intentions are kind and friendly

    ========================================================================

    WARN
    answer = Capistrano::CLI.ui.ask "  Are you sure you want to continue? (Y) "
    if answer == 'Y' then true else false end
  end

  unless fetch(:confirmed)
    puts "\nDeploy cancelled!"
    exit
  end
end

before 'production', :ask_production_confirmation

This isn't compatible with Capistrano 3.0?

@gonace this is:

      set :confirmed, proc {
        puts <<-WARN

    ========================================================================
          WARNING: You're about to overwrite the production database
    ========================================================================

        WARN
        ask :answer, "Are you sure you want to continue? Type 'overwrite'"
        if fetch(:answer)== 'overwrite' then true else false end
      }.call

      unless fetch(:confirmed)
        puts "\nCancelled!"
        exit
      end

      run_locally do
        ask('bubu', 'bobo')
        with rails_env: :development do
          rake 'db:data:dump'
        end
      end

Nice work BTW
