Hi all,
I landed here (via Google) with the same error. Does the error prevent K8s from working correctly? I find the networking driver from Weaveworks to work better with arm boards than Flannel. I'd also recommend using a stock OS over Hypriot. I wrote a guide you guys may enjoy:

I'm in the process of testing it all out on the Tinkerboard. I think it'll work fine once past this error and gives a sense of purpose to the cluster.
Regards,
Alex
