I think one of the issues I had was trying to run pihole with podman on a raspberry pi. I could not get DNS requests to work by just mapping the right ports. I ended up just running with --net=host and it worked, I didn’t feel like debugging further.
I had other issues on my NAS but I don’t remember what it was, I have a lot of services on it, qBittorrent, Wireguard, Jellyfin, Jackett, netdata, prometheus, samba, syncthing, pihole (redundant), wsdd all in docker.
sqlboiler does this in Go
