My preferred way of running a standalone pihole on an atomic host instance.

run_pihole_docker.sh

NAME=pihole
TERM=xterm-256color
TAG='latest'
TZ="America/New_York"
DNS1=10.0.0.1
DNS2=10.0.0.1
IP=10.0.0.14

docker pull diginc/pi-hole:${TAG} &&
docker rm -f ${NAME}
#docker volume ls | awk '/pihole-/{ print $2 }' | xargs docker volume rm
docker run -d \
    --name ${NAME} \
    $(awk '/nameserver/{print "--dns",$2}' /etc/resolv.conf) \
    -v /run \
    -v "${NAME}-config:/etc/pihole/:Z" \
    -v "${NAME}-dnsmasq:/etc/dnsmasq.d/:Z" \
    -p 53:53/tcp -p 53:53/udp -p 80:80 \
    -e TZ="${TZ}" \
    -e ServerIP="${IP}" \
    -e DNS1="${DNS1}" -e DNS2="${DNS2}" \
    -e LIGHTTPD_ENABLED=true \
    --restart=always \
    -e TERM=${TERM} \
    diginc/pi-hole:${TAG}


sleep 1
docker logs ${NAME} 2>/dev/null | grep 'password:'
