Rails, Sidekiq, Redis on Heroku - something wrong

Question

I have a problem with my Rails app.

App based on Ruby on Rails with Sidekiq, Redis and deployed on Heroku. I don't know why my worker doesn't work on Heroku. I think something is wrong in my settings.

config/initializers/sidekiq.rb

Sidekiq.configure_server do |config|
  config.redis = { url: 'redis://localhost:6379/0' }
  schedule_file = "config/sidekiq.yml"
  if File.exists?(schedule_file)
    Sidekiq::Cron::Job.load_from_hash YAML.load_file(schedule_file)
  end
end

Sidekiq.configure_client do |config|
  config.redis = { url: 'redis://localhost:6379/0' }
end

workers/my_worker.rb

class MyWorker

  include Sidekiq::Worker

  def perform
    ......
  end
end

config/sidekiq.yml

my_photos:
  cron: "30 3 */2 * *"
  class: "MyWorker"
  queue: default

Procfile

web: bundle exec rails server -p $PORT
worker: bundle exec sidekiq -e production

application.rb includes line:

config.active_job.queue_adapter = :sidekiq

I have installed Redis To Go on Heroku.

Heroku config:

REDISTOGO_URL: redis://redistogo:2085d9ff......
REDIS_PROVIDER: REDISTOGO_URL
.
.
.

Everything works fine on localhost development and production mode (worker too) but on Heroku worker doesn't work well.

Some errors:

Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)

heroku ps in console displays:

=== web (Free): bundle exec rails server -p $PORT (1)
web.1: up 2019/09/18 16:57:03 +0200

=== worker (Free): bundle exec sidekiq -e production (1)
worker.1: crashed 2019/09/18 17:27:42 +0200

Yes, I restarted Heroku.

***

Heroku logs after change config.redis to ENV['REDISTOGO_URL'] in sidekiq.rb

ricks · Accepted Answer

John is correct, Sidekiq 6 requires at least Redis 4, but Redis To Go has not updated from version 3.

Instead of downgrading to meet the requirements of Redis To Go i would recommended moving dependencies.

Since you are using Heroku, two popular alternatives are Heroku Redis and Redis Cloud.

Since Redis 4 was released 2.5 years ago and Redis 5 is already released, its safe to say that Redis To Go is falling behind and you should strongly consider moving to a dependency that gets updated more frequently.

Neglecting to do so will be more difficult in the long run.

John Coote · Answer

Seems to be a versioning issue:

Sidekiq 6 requires Redis 4, but RedisToGo as provided by Heroku is still using Redis 3.x I stepped around the problem by specifying in my Gemfile:

gem 'sidekiq', '5.2.7'
