"Sure, just pasting the panic stack trace would help" - Sorry I don't know how to do this. Any help, appreciate.

The log just stops at panic: runtime error: index out of range [0] with length 0? That's strange, usually there is a "stack trace" after it (showing source file and line number where the panic happened). Would you please re-run it with LOG_CALLER=short so that the source code file and line number will show for every log lines? Thanks!!

My 100% bad, LOG_CALLER was not implemented in this project, it's now done in commit 482d1ba; would you mind please re-trying by pulling docker pull qmcgaw/dns:v2.0.0-beta and just reporting back with your logs? 🙏 No need for the docker inspect 😉 Thanks!!

You can set LOG_CALLER=short for it to log the file name + line number for every log line.

Oh never mind, 2024-01-24 17:25:49 is the date printed by your interface, not by the internal logger, so LOG_CALLER won't make a difference. Can you try running in a terminal docker logs <container-name-or-id> and report the output? The panic message (multiple lines) is probably hidden by the interface you're using, but it should be there when checking the log file with docker logs 🤔 Thank you!

Hi
Ok, I will try that and report back (still have windows VM installed).
Anyway I already have it running on a VM running Alpine Linux. (Also have tried on Ubuntu and Centos - on both with beta version also get panic error) , on all that I tried beta version the only one that run ok is Alpine Linux.

That's surprising, feel free to share the docker logs from these as well if you can 😉 Thanks again

Feeling even guiltier now 😄
I could reproduce the bug locally, and it indeed did not print the panic stack trace which is strange (my guess is it's because it's in a source file specific to *nix, there is the same file for windows as well)
Anyway, the bug was coming from empty lines in /etc/resolv.conf (the file containing nameserver information), and on some systems there was no empty lines so it would work fine. This is fixed in 6233499 Thank you so much for taking the time to answer all my previous silly questions 😄
