Package request: pi-hole

[LinArcX]

https://github.com/pi-hole/pi-hole Arch package to get ideas how to package it: https://aur.archlinux.org/packages/pi-hole-server/

[boredom101]

I think I'll give this package a try.

[expipiplus1]

@boredom101 looking forward to it!

FWIW I've got pihole running quite nicely in docker from nix with

  docker-containers.pihole = {
    image = "pihole/pihole:latest";
    ports = [
      "${serverIP}:53:53/tcp"
      "${serverIP}:53:53/udp"
      "3080:80"
      "30443:443"
    ];
    volumes = [
      "/var/lib/pihole/:/etc/pihole/"
      "/var/lib/dnsmasq.d:/etc/dnsmasq.d/"
    ];
    environment = {
      ServerIP = serverIP;
    };
    extraDockerOptions = [
      "--cap-add=NET_ADMIN"
      "--dns=127.0.0.1"
      "--dns=1.1.1.1"
    ];
    workdir = "/var/lib/pihole/";
  };

@expipiplus1 Hi, thank you for your reply. But i don't have docker on my system. How to use it like a normal package in nixos?

[expipiplus1]

Hopefully this issue will help answer that very question, @LinArcX

@expipiplus1 It's not clear to me how to use that snippet you posted. Can you show me a complete example?

[lovesegfault]

Oh, I think it got renamed to https://nixos.org/nixpkgs/manual/#ssec-pkgs-dockerTools-buildImage

[expipiplus1]

The docker-containers module is a recent addition (last few months I think).

I also have an nginx virtualhost forwarding http to port 3080 for access to the pihole admin console.

Hope this helps

@boredom101 Did you end up making anything?

[matthiasbeyer]

Any updates here?

[ashkan-leo]

this would be an extremely valuable addition!

[nuxeh]

Any updates? I would consider assisting, or packaging this myself if not.

[ksevelyar]

Any updates? I would consider assisting, or packaging this myself if not.

Could you explain why you want pi-hole? Why you don't want to use plain dnsmasq? Is it dashboard or performance?

 services.dnsmasq.enable = true;
  services.dnsmasq.extraConfig = ''
    domain-needed
    bogus-priv
    no-resolv

    server=208.67.220.220
    server=8.8.4.4

    listen-address=::1,127.0.0.1,192.168.0.1
    bind-interfaces

    cache-size=10000
    log-queries
    log-facility=/tmp/ad-block.log
    local-ttl=300

    conf-file=/etc/nixos/assets/hosts-blocklists/domains.txt
    addn-hosts=/etc/nixos/assets/hosts-blocklists/hostnames.txt
  '';

Pi hole is a well established turnkey solution, which additionally provides monitoring and configuration as you say. I for one wasn't aware that it was so easy to configure dnsmasq to do the same thing so easily, albeit in a slightly less user friendly or visible way.

Really I think it comes down to the fact that people know about pi hole and want to install it on their NixOS system, if there's a package for it that's an advantage, surely?

[horkhork]

I came to a similar conclusion as ksevelyar. I've used pihole for quite a while and it is very nice, but it's got a lot of bells and whistles that aren't really necessary.

I'm in the process of switching to dnscrypt-proxy2, which looks like it will do the job of adblocking just as well as pihole.

I started started to create my own custom channel + derivation for wrapping https://github.com/DNSCrypt/dnscrypt-proxy/blob/master/utils/generate-domains-blacklists/generate-domains-blacklist.py to automate blacklist updates, and while it does work, it might be a bit too crufty to share at this point.

[nuxeh]

It's been a while, but I have the pi-hole tools (pihole and pihole-FTL) packaged and working, and the web interface running. Now I'm just working on the modules, and configuring it all to work as it should.

It's not the easiest project in the world to package, lots of hard-coded paths for the files it needs at runtime, many of which have a mysterious function that needs some research to find out what it's needed for, across quite a lot of bash scripts. Also a couple of small hurdles needed to be overcome to get FTL building with the currently packaged Nix build tools and libraries, and being able to have it spawned by systemd correctly at runtime.

When it's doing something useful, I'll put it on a branch/draft PR so that anyone who's interested can test it.

[JamieMagee]

@nuxeh Thank you for your effort in packaging pi-hole. Could you share your configuration so that others can continue to work on it?

[nuxeh]

@JamieMagee sure, I'll review it and point you to a branch in the next few days. I'm away at the moment and don't have access to my development computer until next week.

[JamieMagee]

@nuxeh Have you had a chance to create a branch for your work?

[nuxeh]

Hey @JamieMagee, apologies, I've had some difficulty getting a chance to look a this again, but here is a branch for the original work I did on it.

https://github.com/nuxeh/nixpkgs/tree/add-pi-hole

I was planning to upgrade all the packages, but they changed the pihole-FTL to using CMake recently, so that turned out to be a non-trivial change, and since I did a certain amount of testing with the 5.0 I thought it could be better to share it with that "working" version.

Here is a vm.nix for testing with nixos-shell:

{ config, pkgs, ... }:

{
  boot.kernelPackages = pkgs.linuxPackages_latest;
  services.openssh.enable = true;

  virtualisation.qemu.networkingOptions = [
    "-net nic,netdev=user.0,model=virtio"
    "-netdev user,id=user.0,hostfwd=tcp::8888-:80"
  ];

  services.pihole = {
    enable = true;
    interface = "eth0";
    webInterface = true;
  };

  networking.firewall.enable = false;
}

Which can be run with the following from a checked out nixpkgs tree:

NIX_PATH=nixpkgs=. nixos-shell

From there, you can access the port-forwarded web UI at http://localhost:8888/pihole/.

Generally regarding my original progress on this, I got the pihole-FTL service to build and run, and the web interface hosted with lighttpd, but after that point, since I haven't actually used pihole before, I wasn't very sure what a "working" install would look like, so I lost some momentum.

The pihole core is a bunch of bash scripts with hard-coded paths, I took a naive approach of attempting to patch all those paths, but somehow feel that there might be a better way to get it working.

Hope this helps!

Not stale. There is a PR in progress.

PSA: In addition to AdGuard Home, NixOS also has a module for blocky. Both seem like nice alternatives to Pi-hole.

[SgtPooki]

Thanks samhh for https://github.com/samhh/dotfiles/commit/8193c3e407306e6f41b291923e6d8be8db19e36a. I tried blocky and dnsmasq and as a NixOS noob I couldn't get them working, but your pihole in docker container .nix file worked flawlessly

https://github.com/TechnitiumSoftware/DnsServer is another alternative. It replaced Pi-hole and Unbound for me. I recently added a package and a module for it.
