I'm trying to install k3s on a raspberry pi running dietpi (https://dietpi.com), using an external mysql database for datastorage. k3s is installed and looks ok, but for some reason it can't resolve the name of the mysql server. The network uses mdns for local names, so the mysql server is identified by

emrys.local

, which (after a few hickups with missing nss libraries and configuration) seems to resolve fine for everything else on the system, but k3s refuses to resolve it. Does k3s do direct DNS lookups? Is there a way to get it to resolve mdns names?

mdsns does not work in golang

Ah, that's too bad. Was not planning on running a DNS server, and maintaining hosts file when using DHCP isn't really a great option either. Guess I'll have to take a step back and have a think. Thanks for the reply.

on home networks there is frequently one built in to your DHCP server, if you’re using dnsmasq or something

Yeah, there used to be one in my linksys router, but I recently switched to a mesh thingy which doesn't. This is only for a homelab.

if the binary is built with cgo enabled.

I'm guessing k3s isn't? 🙂

it is, because we build in sqlite (which is c) but because we do a static build (so as to be portable across distros) we use the pure go resolver

Ok, thanks. I'll have to consider my options another day, todays homelab sessions can't fit a full makeover of name resolution in the network 😄
