Pi-Hole and Unbound with Docker

IMPORTANT: Either use this locally or with a VPN. This project is not meant to be used on a public server.

Setup

1. Start with a new Ubuntu 22 server.
2. Close all ports except 22 TCP for SSH, 53 TCP/UDP for DNS and 80 TCP for the web interface.
3. Install Docker.
4. Run sudo sed -r -i.orig 's/#?DNSStubListener=yes/DNSStubListener=no/g' /etc/systemd/resolved.conf, sudo sh -c 'rm /etc/resolv.conf && ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf' and sudo systemctl restart systemd-resolved.
5. Clone this repository to /srv/pihole-unbound.
6. Run sudo docker-compose up -d in the cloned directory.
7. Get your web interface password with sudo docker logs pihole | grep random.
8. Check if everything is working by browsing to http://<your-ip>/admin and entering the password from the last step.

Update

cd /srv/pihole-unbound && sudo docker-compose down -t 120 && sudo docker-compose pull && sudo docker-compose up -d --remove-orphans && sudo docker image prune
