Pihole + Unbound Docker Compose file

[email protected]

Hi friends.

I've been trying to find docker-compose.yaml for pihole+unbound so I can use pihole as both a recursive dns server and as local dns alongside Nginx Proxy Manager. But since v6 of pihole all the old files I could find don't work properly or at all.

Does anyone here use pihole+unbound in docker?

Thank you very much.

You seem knowledgeable. I have a question about this. I have ran this type of setup before. Every time, I ended up ditching unbound because it throws DNSSEC error. I have tried troubleshooting but it doesn’t work.

Is your ISP interfering?

[email protected]

Not as far as I know. I have never been throttled or anything ever. I have never seen any charges.

How well does that run in docker? I've always liked docker, but it seems to me that certain apps should touch metal than be containerized. Maybe I'm too old school.

I have all these services in docker as well (although not with the docker compose file here) and they run perfectly fine with a very low resource footprint.

I used to use a pihole+unbound single container docker image but technitium is just easier for me. Might be worth exploring other options like adguard home also.

It runs quite well; Docker's not a full fledged virtual machine so much as a virtualization layer. I also love the portability of running this in Docker. I rsync a backup of this and the Appdata folder every night. When or if this server fails, I can be up and running again in minutes on another machine.

I mean in terms of hijacking DNS. Might be worth a look.

How'd it work out?

0K that's cool. I love docker. I would like to upgrade to k8s but I haven't yet plumbed the depths of docker. I was just with the overhead of docker, since Pi-Hole/Unbound is a dedicated system, I thought maybe it'd get better thru put baked in. I wouldn't listen to me tho, I'm medicated.

I don’t think it happens because I have used NextDNS and the logs show my activity.

As an anecdote: I have one system (x86) with pi-hole and unbound in a docker, and a secondary raspberry pi with pi-hole running on bare metal. The docker system (although much more performant in general) has a lower latency as the raspberry bare metal install.

I do exactly the same thing for all three of these services! My implementation is on podman rather than docker, but basically the same deal.

I just went through my setup to verify dnssec settings in unbound to troubleshoot strange latency when removing random names while browsing. Did you verify the unbound certificate file was created and had the proper permissions? There are also a couple other configuration items in unbound related to dnssec that can be tweaked to improve the implementation.

Deleted the WireGuard and modified few other things in docker compose file and so far it's running fine without any errors. So far do good.
