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.
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.
