sidekiq.conf

# /etc/init/sidekiq.conf - Sidekiq config
# This example config should work with Ubuntu 12.04+. It
# allows you to manage multiple Sidekiq instances with
# Upstart, Ubuntu's native service management tool.
#
# See workers.conf for how to manage all Sidekiq instances at once.
#
# Save this config as /etc/init/sidekiq.conf then mange sidekiq with:
# sudo start sidekiq index=0
# sudo stop sidekiq index=0
# sudo status sidekiq index=0
#
# or use the service command:
# sudo service sidekiq {start,stop,restart,status}
#
