Pi-hole with cloudflared DoH (DNS-Over-HTTPS)
This example provides a base setup for using Pi-hole with the cloudflared DoH service. More details on how to customize the installation and the compose file can be found in Docker Pi-hole documentation.

Configuration
.env
Before deploying this setup, you need to configure the following values in the .env file.
- TZ (time zone)
- PIHOLE_PW (admin password)
- PIHOLE_ROUTER_IP (only needed for activated conditional forwarding)
- PIHOLE_NETWORK_DOMAIN (only needed for activated conditional forwarding)
- PIHOLE_HOST_IP (IPv4 address of your Pi-hole - needs to be static)
- PIHOLE_HOST_IPV6 (IPv6 address of your Pi-hole - can be empty if you only use IPv4)
Conditional forwarding (optional, default: enabled)
If you would like to disable conditional forwarding, delete the environment variables starting with "CONDITIONAL_FORWARDING"
Container DNS (optional, default: disabled)
In the docker compose file, dns is added as a comment. To enable dns remove '#' in front of the following lines:
dns:
- 127.0.0.1 # "Sets your container's resolve settings to localhost so it can resolve DHCP hostnames [...]" - github.com/pi-hole/docker-pi-hole
- 1.1.1.1 # Backup server
Deploy with docker compose
When deploying this setup, the admin web interface will be available on port 8080 (e.g. http://localhost:8080/admin).
$ docker compose up -d
Starting cloudflared ... done
Starting pihole ... done
Expected result
Check containers are running and the port mapping:
$ docker ps

Navigate to http://localhost:8080
in your web browser to access the installed Pi-hole web interface.
Stop the containers with
$ docker compose down
# To delete all data run:
$ docker compose down -v
Troubleshooting
- Starting / Stopping pihole-FTL loop:
Sometimes, it can happen that there occurs a problem starting pihole-FTL. I personally had this issue when adding this line to the shared volumes:
- "/pihole/pihole.log:/var/log/pihole.log"
To fix this issue, I found this issue,
which suggested adding an empty file (touch /pihole/pihole.log
) to prevent it from creating a directory.
The directory would not allow starting pihole-FTL and result in something like this:
# Starting pihole-FTL (no-daemon) as root
# Stopping pihole-FTL
...
If you created an empty file, you may also check the ownership to prevent permission problems.

- Environment variables are version-dependent
Environment variables like "CONDIIONAL_FORWARDING*" and "DNS1" are deprecated and replaced by e.g. "REV_SERVER*" and "PIHOLE_DNS" in version 5.8+. Current information about environment variables can be found here: https://github.com/pi-hole/docker-pi-hole
