If I have servers with two IPs (one public and one private) how do I tell k3s to use the private interface for all inter-node communication? Is setting

--flannel-iface

all I need?

yes I also suggest to specify

node-ip

,

node-external-ip

and

bind-address

(this one only on the server node)

I'll look into those tomorrow. Thanks!

if you want to listen on all interfaces

bind-address

is

0.0.0.0

by default so you don't have to configure it.

Uh, wut?

INSTALL_K3s_VERSION

is wrong you have to specify

v1.25.2+k3s1

Ah, documentation wasn't clear, thanks. Also that could error better. 🤣
