pihole-doh

Docker Compose-based Pi-Hole deployment for getting up and running with DNS Over HTTPS. Spins up two containers:

  1. An instance of cloudflared (image provided by crazymax/cloudflared) for proxying DNS lookups to DNS Over HTTPS servers provided by Cloudflare (1.1.1.1) and Quad9 (9.9.9.9). The proxy handles DNS queries on port 5053, though this is only exposed on the local Docker network.
  2. A pi-hole instance (official image pi-hole/docker-pi-hole) configured to use the above DoH proxy as its upstream.

Running

Prerequisites

  1. Docker installed and running
  2. Docker Compose installed
  3. Make installed

Commands

Start

make rebuild # Builds and starts the containers

Pi-Hole’s web interface should now be accessible at http://localhost:5550.

To test that the Pi-Hole’s DNS server is working, run nslookup google.com 127.0.0.1. You should get a response back.

Stop

make stop # Stops the containers

Other

If you'd rather not use the provided make targets, you can also run as a standard Compose application via docker-compose up -d, etc. You can interact with the containers using docker-compose or docker as well, of course.

Host Ports

The cloudflared ports are not exposed on the host. Pi-Hole’s web interface is exposed on a port controlled by the PIHOLE_WEB_PORT environment variable in your local shell. DNS queries into the Pi-Hole go to port 53.

Persistence

Pi-Hole writes its persistence data to ./etc-pihole and ./etc-dnsmasq. To reset the instance between runs, delete these directories.

Configuration

PIHOLE_WEB_PORT

Default: 5550

Set this environment variable in your local shell to change the port where Pi-Hole's web interface can be accessed.

Pi-Hole Web Password

Pi-Hole generates a new web interface password when it starts up, by default. To set a static password that won't change between runs, add a docker-compose.override.yml file to the root of the repository with the following contents:

version: "3"
services:
  pihole:
    environment:
      WEBPASSWORD: 'your_password_here'
