I have a cluster with 1 master ans 1 node on raspberry

My issue is that i cannot have the ready status :

root@master:~# kubectl get nodes

NAME STATUS ROLES AGE VERSION

master NotReady master 37m v1.17.0

raspberrypi NotReady 36m v1.17.0

When i run : kubectl get nodes

i have :

Ready False Sun, 15 Dec 2019 15:48:11 +0100 Sun, 15 Dec 2019 15:07:12 +0100 KubeletNotReady runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized. WARNING: CPU hardcapping unsupported

And : journalctl -u kubelet

Struggling having my cluster working, can anyone help on whats going wrong ?

Thanks
