pihole-unbound

Level up your network with cutting-edge tech. This Docker container effortlessly combines Pi-Hole and Unbound, giving you the ultimate privacy and performance combo in a single package. It's the future of network management, available today.

Note

Development for the development-v6 tag is currently on hold. The development-v6 tag uses Alpine Linux. If you're familiar with Alpine, we encourage you to check out the Dockerfile-Dev-V6 file. Your contributions are highly appreciated!

Supported Architectures

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

Simply pulling rlabinc/pihole-unbound: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
amd64	✅	linux/amd64
arm64	✅	linux/arm64
armhf	✅	linux/arm/v7
armel	✅	linux/arm/v6

Usage

Here are the commands you'll need:

docker run -d --name pihole-unbound \
  --name=pihole-unbound \
  -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` \
  --restart=always \
  rlabinc/pihole-unbound:latest

Docker Tags

The Docker tags supported by this image are:

Tag	Type	Status	Development	Description
latest	Stable		✅	Always latest release
2024.02.2-1.19.3	Stable		✅	Date-based release [Pi-hole Version-Unbound Version]
dev	Beta		✅	Similar to latest, but for the development branch (pushed occasionally)

Note: The development-v6 has been entirely redesigned from the ground up and contains many breaking changes, for more info regarding development-v6 visit here.

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.

Acknowledgements

The code in this image is heavily influenced by MatthewVance's unbound-docker with the help of chriscrowe's docker-pihole-unbound server Docker image configs, However, the upstream projects most certainly also deserve credit for making this all possible.
