Hi,

I have Node-Red running in Alpine with init script= like this:

#!/sbin/openrc-run
NODE_USER=3D"root"
EXEC=3D"n= ode-red"
depend(){
=C2=A0 =C2=A0 =C2=A0 =C2=A0 need net
=C2= =A0 =C2=A0 =C2=A0 =C2=A0 need mosquitto
=C2=A0 =C2=A0 =C2=A0 =C2=A0 need= logger
}
start() {
=C2=A0 =C2=A0 =C2=A0 =C2=A0 ebegin "Start= ing Node RED"
=C2=A0 =C2=A0 =C2=A0 =C2=A0 start-stop-daemon --start= -b -u "${NODE_USER}" --quiet --exec "${EXEC}"
=C2= =A0 =C2=A0 =C2=A0 =C2=A0 eend $?
}
stop() {
=C2=A0 =C2=A0 =C2=A0 = =C2=A0 ebegin "Stopping Node RED"
=C2=A0 =C2=A0 =C2=A0 =C2=A0 = start-stop-daemon --stop --quiet --exec "${EXEC}"
=C2=A0 =C2= =A0 =C2=A0 =C2=A0 eend $?
}

Node red by = default output logs to console.

start-stop-daemon has=C2=A0--stdo= ut and=C2=A0--stdout-logger, but people on the internet seem to prefer pipe= to logger binary. "> /var/log/some.log 2>&1""=C2= =A0=C2=A0

Is it an outdated method or which way is preferr= ed?

I want to redirect logs in such a way=C2=A0that:

- = file is /var/log/node-red.log or /var/log/node-red/log.log

- file= is automatically rotated.

What would be the best = way to achieve this?

Thanks for=C2=A0your help!
