unable to nslookup inside docker container

[CaptainTrex]

I can't get it working no matter what. I am using Technitium DNS server docker container on Fedora 41 and working perfectly for the devices on LAN. But all of my docker containers can not nslookup untill I add "Host IP:53:53" in technitium docker compose file.

Thanks for the post. This is really a docker networking issue that comes for UDP based protocols. Its best if you run your DNS server docker container in "host" network mode and then use your host's IP as DNS for all clients/containers.
