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.
