Node stuck in NotReady state

VinayakPandey

While creating cluster with kind, nodes are stuck in NotReady state with following message

KubeletNotReady runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: cni plugin not initialized

kube-proxy pod was crashing because of
server.go:495] open /proc/sys/net/netfilter/nf_conntrack_max: permission denied

upgrading kind to 0.11.1 fixed the issue

Hi @VinayakPandey, I'm glad you were able to solve the issue!

Many things gets fixed when updating the versions. A similar issue is described here:

https://kubernetes.io/docs/tasks/administer-cluster/migrating-from-dockershim/troubleshooting-cni-plugin-related-errors/

In that case the solution included to upgrade the plugins to the latest version.

Regards,
Luis.
