We tries to deploy k0s in linode (akamai). The vpc in linode seems to do source/dest check (and operates in layer 3), which means that kube-router does not work. to work around this we added a vlan (layer 2), which give the node a second interface, eth1.

Kubelet ended up using the ip of eth0, so we tried to use the privateInterface option in the k0sctl config.

For the controller, it picked up the ip address of eth1 as expected, but the worker nodes did not append --node-ip to kubelet, which led to node to node config not working.

Should privateInterface set --node-ip as an extra arg for kubelet?

setting the privateAddress did appear to work.
