Hello, trying to just do 
kubectl get nodes
on a cluster created by 
k3d
. The command 
kubectl cluster-info
hangs with no output and no clear indication as to what is wrong. I'll paste some diagnostics now. The command used to create the cluster was 
k3d cluster create k8s
Copy code
$ k3d node list
NAME               ROLE           CLUSTER   STATUS
k3d-k8s-server-0   server         k8s       running
k3d-k8s-serverlb   loadbalancer   k8s       running

$ docker ps
