Following is what about dashboard says regarding Dynos:
For the time being, I only need two dynos: web & resque, and I do not need the third one: worker. How can I get rid of it, or is it something default by Heroku, and I'm not allowed to remove it.
If I can't remove it, is there a way that what I'm doing on resque dyno, can I get the same results through woker dyno?
The worker
dyno type is likely being provided by your buildpack. See the output of your deployment:
remote: Procfile declares types -> clock, sidekiq, web
remote: Default types for buildpack -> console, rake, worker
I believe you would have to change what buildpack you are using to remove the worker
dyno type.
