So DNS Black-holing is not new obviously, and what stands out as the go to solution? Pihole probably… and yeah thats what im using because hey its a popular choice. Though I am running it in docker. Combining that with Unbound (also in docker), and configuring outbound DNS to use DNS over TLS, with a few additional minor tweaks, but otherwise mostly standard configuration on both.

Wondering what you guys might be using, and if you are using Pihole and/or Unbound if you have any tips on configuration.

Happy to share my config if there is interest.

    If you don’t mind DM’ing me or dropping it in a comment here it would be greatly appreciated! The docker engine isn’t something entirely new to me so i’m a bit skeptical into thinking that i missed something but always happy to compare with others, actually Docker is what pushed me to switch fully to Linux on my personal computers.

    Snippet from my docker-compose.yml:

      pihole:
        container_name: pihole
        hostname: pihole
        image: pihole/pihole:latest
        networks:
          main:
            ipv4_address: 172.18.0.25
        # For DHCP it is recommended to remove these ports and instead add: network_mode: "host"
        ports:
          - "53:53/tcp"
          - "53:53/udp"
          - "127.0.0.1:67:67/udp" # Only required if you are using Pi-hole as your DHCP server
          - "127.0.0.1:85:80/tcp"
          - "127.0.0.1:7643:443"
        environment:
          TZ: 'America/Vancouver'
          FTLCONF_webserver_api_password: 'insert-password-here'
          FTLCONF_dns_listeningMode: 'all'
        # Volumes store your data between container upgrades
        volumes:
          - './config/pihole/etc-pihole:/etc/pihole'
          - './config/pihole/etc-dnsmasq.d:/etc/dnsmasq.d'
          - '/etc/hosts:/etc/hosts:ro'
      #   https://github.com/pi-hole/docker-pi-hole#note-on-capabilities
        cap_add:
          - NET_ADMIN # Required if you are using Pi-hole as your DHCP server, else not needed
          - CAP_SYS_TIME
          - CAP_SYS_NICE
          - CAP_CHOWN
          - CAP_NET_BIND_SERVICE
          - CAP_NET_RAW
          - CAP_NET_ADMIN
        restart: unless-stopped
        labels:
          - "traefik.enable=true"
          - "traefik.http.routers.pihole.rule=Host(`pihole.my.domain`)"
          - "traefik.http.routers.pihole.entrypoints=https"
          - "traefik.http.routers.pihole.tls=true"
          - "traefik.http.services.pihole.loadbalancer.server.port=80"
          - "traefik.http.routers.pihole.middlewares=fail2ban@file"
     unbound:
       image: alpinelinux/unbound
       container_name: unbound
       hostname: unbound
        networks:
          main:
            ipv4_address: 172.18.0.26
       ports:
         - "127.0.0.1:5334:5335"
       volumes:
         - ./config/unbound/:/var/lib/unbound/
         - ./config/unbound/unbound.conf:/etc/unbound/unbound.conf
         - ./config/unbound/unbound.conf.d/:/etc/unbound/unbound.conf.d/
         - ./config/unbound/log/unbound.log:/var/log/unbound/unbound.log
       restart: unless-stopped
    

    Edit: After re-reading the Unbound github and their documentation it seems i may have missed some volume mounts that are key to the function of Unbound, i’ll definitely have to dive deeper into it.

      I am relatively new to docker as well tbh. I did a lot with virtualization and a lot with linux and never bothered, but I totally get the use case now ha. just an FYI, if you use docker on Windows it runs slower as it has to leverage the Windows subsystem Linux (WSL) and a slightly different docker engine (forget which one). So linux is your best bet. If you do want to use a full VM I found Qemu to be the best option for least resource usage.
