Running Pi-Hole
- Now that Docker is installed, run the following commands to setup the Pi-Hole Docker container and run it
# create working directories
mkdir /home/$USER/docker/pihole -p && mkdir /home/$USER/docker/pihole/dnsmasq.d -p
# run the pihole docker container
docker run -d --name=pihole -e TZ=America/New_York -e WEBPASSWORD=password -v /home/$USER/docker/pihole/:/etc/pihole -v /home/$USER/docker/pihole/dnsmasq.d:/etc/dnsmasq.d -p 80:80 -p 53:53/tcp -p 53:53/udp --restart=unless-stopped pihole/pihole - Once the Pi-Hole container is downloaded and running, open a web browser and navigate to http://DNSorIP/admin
