I am trying to follow docs to setup a one node Kubernetes cluster with Centos 7.
kubeadm init will return no error but kubectl get nodes will return:
NAME STATUS AGE VERSION
[MY_IP] NotReady 22s v1.6.4
system log repeats:
Jun 6 16:21:48 localhost kubelet: W0606 16:21:48.064388 11520 cni.go:157] Unable to update cni config: No networks found in /etc/cni/net.d
Jun 6 16:21:48 localhost kubelet: E0606 16:21:48.064537 11520 kubelet.go:2067] Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
I can only find info about this in Kubernetes github logs but they talk about a bug and I haven't found a workaround. Thanks
Looks like you need a pod network. Have you completed step 3 in the guide here? If you install one of the network overlays (listed at https://kubernetes.io/docs/concepts/cluster-administration/addons/), you should be good to go.
you can run this command
kubectl create -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel-rbac.yml
