A simple Capistrano 3 solution may be:

namespace :rails do
  desc "Run the console on a remote server."
  task :console do
    on roles(:app) do |h|
      execute_interactively "RAILS_ENV=#{fetch(:rails_env)} bundle exec rails console", h.user
    end
  end

  def execute_interactively(command, user)
    info "Connecting with #{user}@#{host}"
    cmd = "ssh #{user}@#{host} -p 22 -t 'cd #{fetch(:deploy_to)}/current && #{command}'"
    exec cmd
  end
end

Then you can call it say, on staging, with: cap staging rails:console. Have fun!
