I have a Kubernetes worker node status not ready. I am using two Ubuntn machines. One master and one worker node. I have added flannel by sudo kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml on the master node after sudo kubeadm init --pod-network-cidr=10.244.0.0/16 .

Information I got from the master node:

From the worker node, I got:

As it says, container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized Also, worker node says Unable to update cni config" err="no networks found in /etc/cni/net.d Should them be the reasons?

Also this is what I got by ps -ef | grep kubelet on the master and worker node
