On a single node k3s install that doesnt have any network interfaces (at times) is there a best set of steps for the install (to keeps things running)?
Right now I have made a fake dummy interface and given it a default route, but I feel like there must be a better way?
And/or is there a better network then flannel I should use? I tried calico, since it claims it will make its own default route for you, but it installed a LOT of pods and this is on a small COTS system that is very limited, so I really love K3s little foot print and dont want the extra stuff.
Another thing I tried was making a interface (that doesn’t really do anything) hold a default route with a low metric, so if the real interface with DHCP ever comes up, it will be the default route.

yeah, that’s the best way to do it. You need a dummy interface with a high-cost default route for kube-proxy to work properly
