ruby-getting-started's Introduction

ruby-getting-started

A barebones Rails app, which can easily be deployed to Heroku.

This application supports the Getting Started on Heroku with Ruby article - check it out.

Running Locally

Make sure you have Ruby installed. Also, install the Heroku CLI (formerly known as the Heroku Toolbelt).

$ git clone [email protected]:heroku/ruby-getting-started.git
$ cd ruby-getting-started
$ bundle install
$ bundle exec rake db:create db:migrate
$ heroku local

Your app should now be running on localhost:5000.

Deploying to Heroku

Using resources for this example app counts towards your usage. Delete your app and database as soon as you are done experimenting to control costs.

By default, apps use Eco dynos if you are subscribed to Eco. Otherwise, it defaults to Basic dynos. The Eco dynos plan is shared across all Eco dynos in your account and is recommended if you plan on deploying many small apps to Heroku. Learn more about our low-cost plans here.

Eligible students can apply for platform credits through our new Heroku for GitHub Students program.

Ensure you're in the correct directory:

$ ls
Gemfile		Procfile	Rakefile	app.json	config		db		log		public		tmp
Gemfile.lock	README.md	app		bin		config.ru	lib		package.json	test		vendor

You should see a Gemfile file. Then run:

$ heroku create
$ git push heroku main
$ heroku run rake db:migrate
$ heroku open

ruby-getting-started's Issues

ruby 2.3.5 while heruko site asks for ruby 2.3.4

On the into Heroku asks for ruby 2.3.4: https://devcenter.heroku.com/articles/getting-started-with-ruby#introduction

Could you please sync the docs and the repo? It was a small waste of time that could be avoided.
Thanks!

Update from Ruby 2.6.6 to 2.6.8 (or 2.7)

This project is using Ruby 2.6.6, however the latest 2.6 release is 2.6.8, as mentioned in the build output when using this repo:

remote:        There is a more recent Ruby version available for you to use:        
remote:                
remote:        2.6.8        
remote:        
remote:        The latest version will include security and bug fixes. We always recommend        
remote:        running the latest version of your minor release.        
remote:                
remote:        Please upgrade your Ruby version.        
remote:                
remote:        For all available Ruby versions see:        
remote:          https://devcenter.heroku.com/articles/ruby-support#supported-runtimes

For bonus points, this repo could be updated to Ruby 2.7 :-)

Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED) excluded from capture: DSN not set

Whenever deploying my Rails 5 app to Heroku I get the following error:

D, [2017-07-24T21:05:01.214198 #524] DEBUG -- : Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED) excluded from capture: DSN not set

Procfile

web: bundle exec puma -C config/puma.rb
worker: bundle exec sidekiq -c 5 -v

config/initializers/redis.rb

require 'redis'

uri = URI.parse Settings.redis.host
redis = Redis.new host: uri.host, port: uri.port, password: uri.password

config/initializers/sidekiq.rb

Sidekiq.configure_server do |config|
    config.redis = { url: Settings.redis.host }
end

Sidekiq.configure_client do |config|
    config.redis = { url: Settings.redis.host }
end
    
# Perform Sidekiq jobs immediately in development,
# so you don't have to run a separate process.
# You'll also benefit from code reloading.
if Rails.env.development?
    require 'sidekiq/testing'
    Sidekiq::Testing.inline!
end

Settings.redis.host equals 'redis://localhost:6379/' in development and my RedisToGo URL in production.
