Upstart config for sidekiq workers

aperture-worker.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 aperture-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}
