Increase worker dyno on Heroku to use with Sidekiq

Question

I have been operating under 0 workers, but need to increase the speed at which I'm processing background tasks. I am using Sidekiq for all of my background workers.

When I increase the worker dyno count to 1, I keep getting this error in my heroku logs:

dont know how to build task 'jobs:work'

From researching this, it seems like the issue is that heroku worker dynos are reliant on delayed_job and I am not using delayed_job anywhere.

If I install delayed_job, what will I have to change to get sidekiq to work? Or do I even need delayed_job?

Answer 1

Update your projects Procfile to specify sidekiq for the worker:

web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
worker: bundle exec sidekiq

Then redeploy your application.

I think Heroku defaults to trying to run delayed_job if you don't specify the worker in your Procfile.
