Adguard Home on Alpine Linux

The official installation method of Adguard Home doesn’t work on Alpine Linux, due to absence of Systemd. However, it’s pretty simple to run it with OpenRC:

1. wget the Adguard archive (from Github), extract to /opt/AdGuardHome

2. add this to /etc/init.d/AdguardHome

   #!/sbin/openrc-run
   #
   # openrc service-script for AdGuardHome
   #
   # place in /etc/init.d/
   # start on boot: "rc-update add adguardhome"
   # control service: "service adguardhome <start|stop|restart|status|checkconfig>"
   #

   pidfile="/run/$RC_SVCNAME.pid"
   command="/opt/AdGuardHome/AdGuardHome"
   command_args="-s run"
   command_background=true
   
   extra_commands="checkconfig"
   
   depend() {
     need net
     provide dns
     after firewall
   }
   
   checkconfig() {
     "$command" --check-config || return 1
   }
   
   stop() {
     if [ "${RC_CMD}" = "restart" ] ; then
       checkconfig || return 1
     fi
   
     ebegin "Stopping $RC_SVCNAME"
     start-stop-daemon --stop --exec "$command" \
       --pidfile "$pidfile" --quiet
     eend $?
   }
   

3. Start the service and enable at boot
   rc-update add adguardhome
rc-service start adguardhome
