# This example file is based on https://github.com/mperham/sidekiq/tree/main/examples/systemd
# To run this as a system service copy file into /lib/systemd/system (Ubuntu).
# scp sidekiq.service root@host_ip:/lib/systemd/system
# Then run:
# - systemctl enable sidekiq
# - systemctl {start,stop,restart} sidekiq
#
# This file corresponds to a single Sidekiq process. Add multiple copies
# to run multiple processes (sidekiq-1, sidekiq-2, etc).
#
# Use `journalctl -u sidekiq -rn 100` to view the last 100 lines of log output.
