NullifyNetwork

I'll preface this by saying this post is just for me, it's for Alpine Linux and specific to one use case where I need a static file webserver but want to reconfigure the domains occasionally.

You can set up self-reloading config if you have a script that watches for file changes to the conf files. Just apk add inotify-tools and then create a script like this in /etc/inotify/nginx-reload.sh and make it chmod u+x nginx-reload.sh:-

#!/bin/bash

set -e

while true; do
    while inotifywait /var/www -e modify --include '.*\.conf'; do
        nginx -s reload
    done
done

You then need to set this up to run on startup using openrc. Put the following in /etc/init.d/nginxreload and again, chmod it u+x:-

#!/sbin/openrc-run

name="Nginx Reloader"
command="/etc/inotify/nginx-reload.sh"
command_args=""
command_user="root"
command_background=true
pidfile="/etc/inotify/nginx-reload.pid"

depend() {
        need net localmount
}

Now run:-

rc-update add nginxreload default
service nginxreload start

And any edits to the conf files specified result in nginx reloading its configuration.
