# add docker gpg key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# add docker software repository
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
# install docker
sudo apt install docker-ce docker-compose containerd.io -y
# enable and start docker service
sudo systemctl enable docker && sudo systemctl start docker
# add the current user to the docker group
sudo usermod -aG docker $USER
# reauthenticate for the new group membership to take effect
su - $USER
# edit resolvd config
sudo nano /etc/systemd/resolved.conf
03. Uncomment the line starting with DNSStubListener= and set the value to no
DNSStubListener=no
04. Press CTRL+O, Enter, CTRL+X to write the changes to resolved.conf
05. Continue with the following commands to restart systemd-resolve to free up port 53

Running Pi-Hole
--------------------------------------------------------------------
01. 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
02. Once the Pi-Hole container is downloaded and running, open a web browser and navigate to http://DNSorIP/admin
