Currently have nice long docker compose file that hosts my PiHole V6 container (along with a bunch of other containers) however, reason i ask this question is because whenever I go to pull an updated image and recreate the container I experience about 20 minutes of no DNS resolution which to my knowledge is due to the NTP clock being out of sync.
What’s the best way to host a DNS sinkhole/resolver that can mitigate this issue?
Was thinking of utilizing Proxmox & LXC but I suspect I’ll get the same experience.
Update: Turns out PiHole doesn’t support two instances, I got both of them on separate devices also set the 2nd DNS server in my routers WAN & LAN DNS settings which did in fact split DNS between both instances however, I lost access to my routers web-ui, my Traefik instance & reverse proxies died and I lost all internet access.
So, don’t do what I did.
Update 2: So everything I said in my first update let’s disregard that, turns out I had my router forcing all DNS to PiHole server 1 which caused my issues mentioned above.
Two servers appears to work!
How do I use nixos for docker? I’ve tried before but what I want is to be able to pull docker compose from a git and deploy it. I haven’t been able to find an easy way to do that on docker
Most of the time you don’t need docker. NixOS isolates runtimes.
That being said, you could use nix to build the docker container, and then run it using the built-in oci-container options.
