Description=Puma Rack Server
# Puma supports systemd's `Type=notify` and watchdog service
# monitoring, if the [sd_notify](https://github.com/agis/ruby-sdnotify) gem is installed,
# as of Puma 5.1 or later.
# On earlier versions of Puma or JRuby, change this to `Type=simple` and remove
# the `WatchdogSec` line.
[Service]
Type=simple
# If your Puma process locks up, systemd's watchdog will restart it within seconds.
#WatchdogSec=10
