# /etc/init/sidekiq.conf - Sidekiq config
# source: https://github.com/mperham/sidekiq/blob/master/examples/upstart/sidekiq.conf

# 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 manage sidekiq with:
#   sudo start sidekiq index=0
#   sudo stop sidekiq index=0
#   sudo status sidekiq index=0
#
# Hack Upstart's reload command to 'quiet' Sidekiq:
#
#   sudo reload sidekiq index=0
#
# or use the service command:
#   sudo service sidekiq {start,stop,restart,status}
#

description "Sidekiq Background Worker"

# This script is not meant to start on bootup, workers.conf
# will start all sidekiq instances explicitly when it starts.
#start on runlevel [2345]
#stop on runlevel [06]

# TERM is sent by sidekiqctl when stopping sidekiq. Without declaring these as
# normal exit codes, it just respawns.

# Older versions of Upstart might not support the reload command and need
# this commented out.

# Upstart waits 5 seconds by default to kill the a process. Increase timeout to
# give sidekiq process enough time to exit.
