You might put that giant wall of text in a thread next time

container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: cni plugin not initialized

Did you disable flannel?

Are you missing vxlan support in your kernel?

sorry about that the giant wall of text

No i didnt disable flannel. not sure what that is

I should note that the node status was ready until I tried to add a worker node onto the cluster

I don’t see the other node in the cluster

Do they both have the same hostname or something?

or are you trying to run k3s twice on the same node?

what do the k3s service logs say on that node?

No, I have two Pynq and they have different hostnames. But I had turned off one of the devices.

I realized I was using the wrong IP address for my master and thats why I was not seeing the worker node. Not sure if thats the reason why I was having the notready state. However I changed the IP address and now I see both the master and worker node present and status is ready

Thank you for your help
