Deploying Sidekiq on Ubuntu - Production

sidekiq-manager.conf

# /etc/init/sidekiq-manager.conf - manage a set of Sidekiqs

# 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 sidekiq.conf for how to manage a single Sidekiq instance.
#
# Use "stop workers" to stop all Sidekiq instances.
# Use "start workers" to start all instances.
# Use "restart workers" to restart all instances.
# Crazy, right?

# Set this to the number of Sidekiq processes you want

# /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 app=/path/to/app index=0
#   sudo stop sidekiq app=/path/to/app  index=0
#   sudo status sidekiq app=/path/to/app index=0
#
# or use the service command:
#   sudo service sidekiq {start,stop,restart,status}
