Netbird Support/Discussion Thread

Integrate netbird with uci

@NemYr

I'm playing a bit with netbird, and I feel like the netbird package lacks configuration customization.
Thats why I modified it a bit to have a /etc/config/netbird configuration file so you can actually tune it a bit, here are the files for thoses who are interested in the same feature:

The service file in /etc/init.d/netbird:

#!/bin/sh /etc/rc.common

START=90
STOP=10
USE_PROCD=1

handle_netbird_instance() {
	local section="$1"

	config_get_bool enabled "$section" 'enabled' 0
	if [ $enabled -le 0 ]; then
		return 1
	fi
	
	config_get_bool allow_server_ssh "$section" 'allow_server_ssh' 0
	config_get daemon_addr "$section" daemon_addr
	config_get config "$section" config
	config_get log_level "$section" log_level
	config_get log_file "$section" log_file
	config_get management_url "$section" management_url

	allow_server_ssh_value="false"
	if [ ${allow_server_ssh} -gt 0 ]; then 
		allow_server_ssh_value="true"
	fi

	config_filename="${config:-/etc/netbird/config.${section}.json}"

	[ -f "${config_filename}" ] && sed 's/"ServerSSHAllowed"\s*:[^,]*/"ServerSSHAllowed": '"${allow_server_ssh_value}"'/' "${config_filename}"

	procd_open_instance "$section"
	procd_set_param command /usr/bin/netbird
	procd_append_param command service run
	procd_append_param command --config "${config_filename}"
	procd_append_param command --log-level "${log_level:-info}"
	procd_append_param command --daemon-addr "${daemon_addr:-unix:///var/run/${section}.sock}"
	procd_append_param command --log-file "${log_file:-syslog}"
	procd_append_param command --management-url "${management_url:-https://api.netbird.io:443}"
	procd_set_param pidfile /var/run/netbird.pid
	procd_close_instance

	return 0
}

handle_netbird_triggers() {
	local section="$1"

	config_get_bool enabled "$1" 'enabled' 0
	if [ $enabled -le 0 ]; then
		return 1
	fi

	config_get trigger_iface "$section" trigger_iface
	if [ -z "$trigger_iface" ]; then
		return 1
	fi

	procd_add_interface_trigger "interface.*" "$trigger_iface" /etc/init.d/netbird restart
}

service_triggers() {
	config_load 'netbird'
	config_foreach handle_netbird_triggers netbird
}

start_service() {
	config_load 'netbird'
	config_foreach handle_netbird_instance netbird
}

The configuration file in /etc/config/netbird:

#config netbird netbird
#    option enabled '1'
#    option allow_server_ssh '0'
#    option daemon_addr 'unix:///var/run/netbird.sock'
#    option config '/etc/netbird/config.json'
#    option log_level 'info'
#    option log_file 'syslog'
#    option management_url 'https://api.netbird.io:443'
#    option trigger_iface 'wan'
