Pihole + Unbound + Hyperlocal

IMPORTANT: When using this Docker image, please report any bugs or suggestions to this repository directly.

Overview

Pihole + Unbound + Hyperlocal

Introduction

Pi-hole:

Pi-hole is a DNS sinkhole that protects your devices from unwanted content, without installing any client-side software.

Unbound:

Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards.

Hyperlocal:

To spare the initial DNS query to the DNS-Root-Servers by Unbound, we provide Unbound with an appropriate configuration. With each Pi-hole update, the DNS-Root-Zone (root.hints) is also updated.

Prerequisites

Install Docker
Install Docker-Compose
Download the repository to your favored directory

First startup

Copy example.env to .env and change the parameters

cp example.env .env
vi .env

Start the container

docker-compose up -d

Check the logs

docker-compose logs -f

resolv.conf

If you get the following error

pihole  | Starting unbound
pihole  |   [✗] DNS resolution is currently unavailable

uncomment the following line in the docker-compose.yaml

#- ./resolv.conf:/etc/resolv.conf

and restart the container

docker-compose up -d --force-recreate

Testing

docker exec -it pihole-unbound bash
dig github.com @127.0.0.1 +short
dig sigfail.verteiltesysteme.net @127.0.0.1 | grep status 
dig sigok.verteiltesysteme.net @127.0.0.1 | grep status

First dig should show an IP address
Second dig should show status: SERVFAIL
Last dig should show status: NOERROR

DNS problems

If you are running other docker containers on the same host and cannot use name resolution within these containers, you have to modify /etc/resolvconf.conf on your host system and uncomment the following:

# If you run a local name server, you should uncomment the below line and
# configure your subscribers configuration files below.
name_servers=127.0.0.1

Write the changes to your resolv.conf:

sudo resolvconf -u
