Heroku migration to Cedar - "ERROR: No application configured, nothing to run"

I am trying to migrate my old Heroku Ruby on Rails application from Bamboo to Cedar stack. I am using Ruby 1.8.7, Rails 2.3.11 and Postgres database.

I do everything as described on https://devcenter.heroku.com/articles/cedar-migration but by application start I get the message in heroku log:

"ERROR: No application configured, nothing to run"

My Procfile:

web: bundle exec puma -C config/puma.rb

config/puma.rb:

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
port        ENV['PORT']     || 3000
environment ENV['RACK_ENV'] || 'development'

on_worker_boot do
  # Worker specific setup for Rails 4.1+
  # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
  ActiveRecord::Base.establish_connection
end

Gemfile:

source 'http://rubygems.org'
ruby '1.8.7'
gem 'rake', '~> 0.8.3'
gem 'rails', '2.3.11'
gem 'puma'
gem 'pg', '0.14.1'
gem 'rdoc'

Rakefile:

# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require(File.join(File.dirname(__FILE__), 'config', 'boot'))

require 'rake'
require 'rake/testtask'
require 'rdoc/task'
require 'tasks/rails'

Local bundle install works fine. I invoke command like this on the server:

$ heroku buildpack:set https://github.com/heroku/heroku-buildpack-ruby#legacy-ruby-1.8.7

After pushing commit to Heroku and performing successful database migration I am still getting logs:

Edit 1:

Малъ, thank you for your answer. I performed all of the steps you recommend up to point 8. Then I pushed changes to Heroku. Logs are now like that:

Then I try to updating rack version in Gemfile to 1.1.0, invoked

$ bundle update rack

and uploaded sources once again. Logs:

Now I don't know completely how I could deal with that.

Edit 2:

I noticed that the sed command failed and didn't changed vendor/rails/actionpack/lib/action_controller.rb so I've added lacking line to it:

gem 'rack', '~> 1.4.0'

Current logs:

Edit 3:

I forgot to delete the line with rack 1.1.0 version in vendor/rails/actionpack/lib/action_controller.rb. Now application is up and works like a charm. Малъ, you are my salvator! Big thanks.

Solution

  • I've done some steps to run my Rails 2.3 app on heroku cedar-10 stack. Unfortunately it will be also removed soon, in such way the heroku support answered. So:

    1. Upgrade or downgrade rubygems to 1.4.2, it is required to run rake freeze:

      $ gem update --system 1.4.2

    2. Add rake into Gemfile. and bundle setup.

    3. According the manual, you have to at first freeze Rails gems into /vendor folder:

      $ rake rails:freeze:gems

    4. Modify file: vendor/rails/actionpack/lib/action_controller.rb to support rack 1.4.0 version:

      $ sed "s/gem 'rack', '~> 1.1.0'/gem 'rack', '~> 1.4.0'/" -i vendor/rails/actionpack/lib/action_controller.rb

    5. Add rack 1.4.0, and puma 2.3.2 gems to Gemfile, and remove rails gem from it, then bundle setup again:

      gem 'rack', '~> 1.4.0'
gem 'puma', '~> 2.3.2'

      NOTE: the config/puma.rb is also not needed anymore.

    6. Change Procfile to run puma via rackup:

      $ cat Procfile
web: bundle exec rackup -s puma -p ${PORT:-3000} -E ${RACK_ENV:-development}

    7. Add config.ru to run Rails app from rackup:

      $ cat config.ru
# RAILS_ROOT/config.ru
require "config/environment"

use Rails::Rack::LogTailer
use Rails::Rack::Static
run ActionController::Dispatcher.new

    8. Add the changed and newly added files into git, and push changes to heroku.

    9. Since the heroku uses PostgreSQL in production by default, create MySQL db instance, of course if you plan to use it, accoriding the manual:

      $ heroku addons:add cleardb:ignite
-----> Adding cleardb to sharp-mountain-4005... done, v18 (free)

$ heroku config | grep CLEARDB_DATABASE_URL
CLEARDB_DATABASE_URL => mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true

$ heroku config:set DATABASE_URL='mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true'
