# This sample rc script eliminate the need to use sysutils/py-supervisor to
# run NetBox as a system service. Only www/py-gunicorn is needed as a WSGI.
#
# Of course a working HTTP server like Apache/nginx is still required to make
# use of the gunicorn WSGI.

#
# PROVIDE: netbox
# REQUIRE: DAEMON
# KEYWORD: shutdown
#
# Add the following line to /etc/rc.conf.local or /etc/rc.conf
# to enable netbox:
#
# netbox_enable (bool):			Set to NO by default.
#					Set it to YES to enable netbox.
# netbox_use_config (bool):		Set to NO by default.
#					If set, read the configuration parameter from file defined in
#					"netbox_config" instead using rc variables.
# netbox_config (str):			Default to "%%LOCALBASE%%/etc/${name}.conf.py}"
#					Config file for gunicorn's netbox config file
# netbox_command (str):			Default to "%%LOCALBASE%%/bin/gunicorn"
#					Path to gunicorn to run netbox
# netbox_bind (str):    		Default to "localhost:8001"
#					Interface and port to bind to
# netbox_workers (int):			Default to "5"
#					Number of gunicorn workers
# netbox_threads (int):			Default to "3"
#					Number of worker threads per handling request
# netbox_timeout (int):			Default to "120"
#					Worker timeout for gunicorn
# netbox_max_requests (int):		Default to "5000"
#					Maximum number of requests a worker process will process before respawning
# netbox_max_requests_jitter (int):	Default to "500"
#					Maximum number jitter to add to "netbox_max_requests"
# netbox_extra_args (str):		Not set by default
#					Extra arguments that are passed to gunicorn
