Where I can find CNI parameter passed to kubelet service… What mean /opt/cni/bin/ and /etc/cni/net.d/ these two path… these two path help to identify CNI plugin details but How we can navigate to this path from kubelet service…

Hi @Basavraj Nilkanthe it will be kubeadm-flags.env

cat /var/lib/kubelet/kubeadm-flags.env
KUBELET_KUBEADM_ARGS="--network-plugin=cni --pod-infra-container-image=<http://k8s.gcr.io/pause:3.4.1|k8s.gcr.io/pause:3.4.1>"

By default kubelet will read the cni configuration from /etc/cni/net.d/

okay these are standard path for kubelet service to read CNI plugins
