运行 rake 任务以在 Heroku 上启动 Resque 工作线程

因此，我在 Heroku 上设置了 Resque 和 redis，这就是我的 resque.rake 文件的样子：

require 'resque/tasks'

task "resque:setup" => :environment do
  ENV['QUEUE'] = '*'
end

desc "Alias for resque:work (To run workers on Heroku)"
task "jobs:work" => "resque:work"

我运行了 heroku rake jobs:work 并让一名工作人员运行。这非常有效。我的后台工作正在完成。

然后我对代码做了一些更改，推送到heroku，仍然看到有一个工作线程在运行。然而，当作业被添加到队列中时，工作人员没有收到任何作业。所以我再次运行 heroku rake jobs:work ，它说我有两个工作人员正在运行，并且我的工作正在完成。

我的问题是为什么会发生这种情况？我每次推送到heroku 时都需要运行这个rake 任务吗？有没有办法自动执行此操作？另外，虽然我有两个工人在运行，但似乎只有一个在工作。有没有办法回到一个工人那里？

So I have Resque and redis to go set up on Heroku and this is what my resque.rake file looks like:

require 'resque/tasks'

task "resque:setup" => :environment do
  ENV['QUEUE'] = '*'
end

desc "Alias for resque:work (To run workers on Heroku)"
task "jobs:work" => "resque:work"

I ran heroku rake jobs:work and got one worker running. This worked perfectly. My background jobs were being completed.

Then I made some changes in my code, pushed to heroku, and still saw that I had one worker running. However, while jobs were being added to the queue, the worker was not receiving any jobs. So I ran heroku rake jobs:work again, it said I had two workers running, and my jobs were being completed.

My question is why did this happen? Do I need to run this rake task every time I push to heroku? Is there a way to automate this? Also, although I have two workers running, there seems to be only one that is working. Is there a way to get back to one worker?
