Can't launch pods on worker

I'm getting these kubelet errors and calico/kube-proxy won't start on the worker.

  • Hi @tiffanyfay,

    Depending on the exercise you are on, there may have been several steps that eventually lead up to this behavior.

    What exercise are you currently working on and what steps did you run prior to this behavior? Were all prior steps successful? Any discrepancies between your outputs and the ones presented in the lab guide?

    Regards,
    -Chris
