Pi-Hole & Cloudflared DoH (DNS-over-HTTPS) Docker

This docker image is now offically supported by the Docker-Sponsored Open Source program and should now be built whenever Pi-Hole updates.

Even though the last commit on this repository may be old, unless stated so, this project is still being mantained. No commits just mean that there is nothing for me to update.

DONT USE YOUR OWN PIHOLE DOCKER COMPOSE, OTHERWISE DoH WILL NOT BE CONFIGURED

After install, please restore your backup to the new pihole installation.

Do not mess up with the DNS settings in the new pihole installation, otherwise your DoH might not work.

---

This docker completes this tutorial (https://docs.pi-hole.net/guides/dns/cloudflared/) and uses it to install DoH on a new pihole installation (https://hub.docker.com/r/pihole/pihole). No matter the age of this docker, it should work, unless, pihole changes their repo, docker-compose.yml, or if cloudflared changes their config layout, or if they change their cloudflared download link. If for some reason it fails to work, please contact me using the contact info at the end of this README.
