Docker Pi-Hole for ARMv7

A Docker container built on Debian to run pi-hole ad filter

Original x86 GitHub repository: https://github.com/lp-lab/dockerPiHole

Environment variables

This container accepts a number of variables passed by Docker command line via -e switch

Variable	Default value	Description
ServerIP	NONE - REQUIRED	The IP address of the pi-hole container
ADMIN_PASS	NONE - REQUIRED	The admin password for the pi-hole web interface
DNS1	8.8.8.8 - Google	Primary DNS
DNS2	8.8.4.4 - Google	Secondary DNS

docker run -p 53:53 -p 53:53/udp -p 80:80 -d --name pihole -e ADMIN_PASS="reallysecurepassword" -e DNS1="10.0.0.1" -e DNS2="10.0.0.2" -e ServerIP="10.0.0.3" lplab/pihole:latest

Running Docker Pi-Hole

The bare minimum to run this container is:

docker run -p 53:53 -p 53:53/udp -p 80:80 -d --name pihole -e ADMIN_PASS="reallysecurepassword" -e ServerIP="IP.ADDRESS.OF.CONTAINER" lplab/pihole:latest

it will start the container and automatically update the blocked domain list.

Volume mounts

Starting with version 2.0.2, even /var/log is automatically binded to a docker volume, so there's no need to mount it from command line

Starting with version 2.0.0 of this container, released on June 16th 2017, pihole-FTL uses a sqlite DB to store queries, located on /etc/pihole directory, so the container now automatically creates a volume to store this directory, there's no need to mount any file in /etc/pihole and can be safely removed from the command line

There are some useful volume mounts, passed via -v switch to the Docker command line:

• -v /etc/localtime:/etc/localtime:ro
• -v /etc/timezone:/etc/timezone:ro

to allow the container to use your system timezone, for query graph renders.

• -v /srv/pihole/etc/hosts:/etc/hosts

for manual adding of certain hostname.

Always remember to mkdir/touch directory and files before the container startup or Docker will create directory for every mount.

Upgrades

To upgrade download the new version from Docker's hub

docker pull lplab/pihole:latest

then stop the running container

docker rm -f pihole

and restart the new pihole using the same command line as above.
