How do you add a worker dyno to a Heroku project?

Question

How do you add a Worker dyno to a Heroku app? Their help system includes some information: https://devcenter.heroku.com/articles/background-jobs-queueing including the instruction to use the command line to scale your app: ``` $ heroku ps:scale web=1 worker=5 ``` This returns the response that workers are not defined. The UI also has a page for adjusting resources: But it does not include the option to add workers.

Accepted Answer

You need to have a worker in your Procfile and then worker dyno settings will appear in UI.

Just add

```
worker: command_to_run_your_worker
```

to your Procfile and after that you will be able to scale workers.
