This will run both Pi-hole and cloudflared at the same time.
cloudflared uses DNS-over-HTTPS, so no one could peak into what you resolved.
Note: we will install Docker Compose from PIP3 because it is newer than apt.
# Install Docker
curl -sSL https://get.docker.com | sh
sudo systemctl enable docker
sudo systemctl start docker
sudo usermod -aG docker pi
# Install Docker Compose
sudo apt update
sudo apt install python3-pip
sudo pip3 install docker-compose
# Cache a version of cloudflared just in case if no DNS is available
cd external
curl -LO https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64.deb
# Reboot
sudo rebootUpdate the .env file with corresponding settings.
Run Pi-hole in Docker Compose.
docker-compose up --detach
docker-compose logs # to see the default random passworddocker-compose exec pihole pihole -a -pYou will need dig which can be installed from dnsutils.
sudo apt install dnsutils
dig github.com @localhostAlthough Gravity Database is updated on Pi-hole start, to update-on-demand, run:
docker-compose exec pihole pihole updateGravityThere is a sync file which help synchronizing configuration between Pi-holes thru scp. Please make sure SSH keys are properly set through ~/.ssh/authorized_keys.
Modify pihole.service to point to the correct directory.
chmod +x service
sudo ln -s /home/pi/repos/pihole/pihole.service /etc/systemd/system/pihole.service
sudo systemctl enable pihole
sudo systemctl start piholeTo update Pi-hole, modify /etc/crontab to reboot, or restart the Docker Compose service on a schedule. When the service is started, it will pull the latest pihole/pihole image and rebuild cloudflared with latest version.
