PiHole on Docker

Hi,

in order to execute a pihole within a docker environment, I found this script from pi-hole repo very usefull. All you have to do is to adjust the ServerIP option

#!/bin/bash

# https://github.com/pi-hole/docker-pi-hole/blob/master/README.md

PIHOLE_BASE="${PIHOLE_BASE:-$(pwd)}"
[[ -d "$PIHOLE_BASE" ]] || mkdir -p "$PIHOLE_BASE" || { echo "Couldn't create storage directory: $PIHOLE_BASE"; exit 1; }

# Note: ServerIP should be replaced with your external ip.
docker run -d \
    --name pihole \
    -p 53:53/tcp -p 53:53/udp \
    -p 1080:80 \
    -p 10443:443 \
    -e TZ="Europei/Berlin" \
    -v "${PIHOLE_BASE}/etc-pihole/:/etc/pihole/" \
    -v "${PIHOLE_BASE}/etc-dnsmasq.d/:/etc/dnsmasq.d/" \
    --dns=127.0.0.1 --dns=1.1.1.1 \
    --restart=unless-stopped \
    --hostname pi.hole \
    -e VIRTUAL_HOST="pi.hole" \
    -e PROXY_LOCATION="pi.hole" \
    -e ServerIP="192.168.1.7" \
    pihole/pihole:latest

printf 'Starting up pihole container '
for i in $(seq 1 20); do
    if [ "$(docker inspect -f "{{.State.Status}}" pihole)" == "running" ] ; then
        printf ' OK'
        echo -e "\n$(docker logs pihole 2> /dev/null | grep 'password:') for your pi-hole: https://${IP}/admin/"
        exit 0
    else
        sleep 3
        printf '.'
    fi

    if [ $i -eq 20 ] ; then
        echo -e "\nTimed out waiting for Pi-hole start, consult your container logs for more info (\`docker logs pihole\`)"
        exit 1
    fi
done;

I’ve modified the ./etc-pihole/pyhole-FTL.conf and configured the following:

DBFILE=
MAXDBDAYS=0
DBINTERVAL=0
PRIVACYLEVEL=0

This is to ensure the db file doesnt grow to gigabytes and slowdown your DNS latency.
