pihole-bind9 is a Docker container to run Pi-Hole & Bind on the same container.

Supported Architectures

We utilise the docker buildx for multi-platform awareness. More information is available from docker here.

Simply pulling rlabinc/pihole-bind9:latest should retrieve the correct image for your arch, but you can also pull specific arch images via --platform.

The architectures supported by this image are:

Architecture Available Platform
x86-64 ✅ linux/amd64
arm64 ✅ linux/arm64
armhf ✅ linux/arm/v7
armv6 ✅ linux/arm/v6
i386 ✅ linux/386

Usage

Here are the commands you'll need:

docker run -d --name pihole-bind9 \
  --name=pihole-bind \
  -e TZ=Europe/London `#optional` \
  -p 53:53/tcp -p 53:53/udp \
  -p 80:80/tcp `#Pi-hole web interface port` \
  -e WEBPASSWORD='qwerty123' `#better to use single quotes` \
  -e DNSSEC_VALIDATE=auto \
  --restart=always \
  rlabinc/pihole-bind9:latest

Docker Tags

The Docker tags supported by this image are:

Tag Type
latest Stable
date Stable
dev Beta

Note: Date tag images aren't the same as the official ones, they're based on the build date.

Installing on Ubuntu

Modern releases of Ubuntu (17.10+) include systemd-resolved which is configured by default to implement a caching DNS stub resolver. This will prevent pi-hole from listening on port 53. The stub resolver should be disabled with: sudo sed -r -i.orig 's/#?DNSStubListener=yes/DNSStubListener=no/g' /etc/systemd/resolved.conf

This will not change the nameserver settings, which point to the stub resolver thus preventing DNS resolution. Change the /etc/resolv.conf symlink to point to /run/systemd/resolve/resolv.conf, which is automatically updated to follow the system's netplan: sudo sh -c 'rm /etc/resolv.conf && ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf' After making these changes, you should restart systemd-resolved using systemctl restart systemd-resolved

Once pi-hole is installed, you'll want to configure your clients to use it (see here). If you used the symlink above, your docker host will either use whatever is served by DHCP, or whatever static setting you've configured. If you want to explicitly set your docker host's nameservers you can edit the netplan(s) found at /etc/netplan, then run sudo netplan apply. Example netplan:

network:
    ethernets:
        ens160:
            dhcp4: true
            dhcp4-overrides:
                use-dns: false
            nameservers:
                addresses: [127.0.0.1]
    version: 2

Note that it is also possible to disable systemd-resolved entirely. However, this can cause problems with name resolution in vpns (see bug report). It also disables the functionality of netplan since systemd-resolved is used as the default renderer (see man netplan). If you choose to disable the service, you will need to manually set the nameservers, for example by creating a new /etc/resolv.conf.

Users of older Ubuntu releases (circa 17.04) will need to disable dnsmasq.

Parameters

Container images are configured using parameters passed at runtime (such as those above).

Parameter Function
-e TZ=Europe/London Specify a timezone to use EG Europe/London.
-p 53:53/tcp -p 53:53/udp Default DNS port to use.
-p 80:80/tcp Specify Pi-hole web interface port.
-e WEBPASSWORD='qwerty123' Specify Pi-hole web interface password. It is better to use single quotes.
-e DNSSEC_VALIDATE=auto This variable defines the DNSSEC validation in Bind.
--restart=always To make sure "It's Always DNS" does not happen.

This Docker container supports both Pi-hole official Docker container all environment variables available here & cytopia's docker-bind Docker container all environment variables available here.

Acknowledgements

The code in this image is heavily influenced by cytopia's docker-bind server Docker image configs, However, the upstream projects most certainly also deserve credit for making this all possible.
