My deploy failed, saying "No Procfile found." What should I do?
The Procfile should list process types and the commands associated with them. For example, if you’re running a Rails app with one Sidekiq worker process, you might have the following Procfile:
1 2 web: bundle exec rails server -b 0.0.0.0 -p $PORT worker: bundle exec sidekiq
This will deploy two sets of containers (“services”) for your app, one for the web process and another for the worker. These services may be scaled independently.
