Sidekiq工作排队但没有在Heroku上处理

Question

Rails 5.2 redis 4.0.1 sidekiq 5.1.3

Heroku上的RedisToGo

Proc文件：

web: bundle exec puma -C config/puma.rb
worker: bundle exec sidekiq -e production -C config/sidekiq.yml

sidekiq.yml

development:
  :concurrency: 5
production:
  :concurrency: 6
:queues:
  - default

配置/初始化/ sidekiq.rb

if Rails.env.production?

  Sidekiq.configure_client do |config|
    config.redis = { url: ENV['REDISTOGO_URL'] || ENV['REDIS_URL'], size: 1 }
  end

  Sidekiq.configure_server do |config|
    pool_size = ENV['SIDEKIQ_DB_POOL'] || (Sidekiq.options[:concurrency] + 2)
    config.redis = { url: ENV['REDISTOGO_URL'] || ENV['REDIS_URL'], size: pool_size }

    Rails.application.config.after_initialize do
      Rails.logger.info("DB Connection Pool size for Sidekiq Server before disconnect is: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      ActiveRecord::Base.connection_pool.disconnect!

      ActiveSupport.on_load(:active_record) do
        db_config = Rails.application.config.database_configuration[Rails.env]
        db_config['reaping_frequency'] = ENV['DATABASE_REAP_FREQ'] || 10 # seconds
        db_config['pool'] = pool_size
        ActiveRecord::Base.establish_connection(db_config)
        Rails.logger.info("DB Connection Pool size for Sidekiq Server is now: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      end
    end
  end
end

我不知道为什么这份工作被困在队列里。这项工作对我当地的发展有效。

任何帮助表示赞赏。

更新！ 根据这里的评论是heroku ps的输出：

=== web (Free): bundle exec puma -C config/puma.rb (1)
web.1: up 2018/06/15 18:49:56 +0700 (~ 5s ago)

=== worker (Free): bundle exec sidekiq -q default (1)
worker.1: crashed 2018/06/15 18:49:51 +0700 (~ 10s ago)

似乎一名工人因某种原因而坠毁。

Answer 1

安装Heroku Postgres作为插件，然后将环境变量添加到您的项目中，一切都应该正常工作。 - https://elements.heroku.com/addons/heroku-postgresql

Answer 2

在与Heroku的技术支持人员交谈之后，事实证明我需要改变我对db yaml文件进行编码的方式。

我将其更改为以下内容：

production:
  url: <%= ENV['DATABASE_URL'] %>

这似乎解决了这个问题。
