Hello I am very new to rancher and kubernetes.
I have a rancher server 2.4.4 and added a cluster node (running RedHat Atomic OS) using below command
sudo docker run -d --privileged --restart=unless-stopped --net=host -v /etc/kubernetes:/etc/kubernetes -v /var/run:/var/run rancher/rancher-agent:v2.4.4 --server https:// --token --ca-checksum --etcd --controlplane --worker.
After that when i tried to deploy a simple hello-world app and getting bellow error
“kube-system Warning FailedCreatePodSandBox coredns-7c5566588d-vzgqx (combined from similar events): Failed to create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container “b6f5d18da314215755b5d5111ec58a277ad244469665cc21d785d37ac953084d” network for pod “coredns-7c5566588d-vzgqx”: networkPlugin cni failed to set up pod “coredns-7c5566588d-vzgqx_kube-system” network: stat /var/lib/calico/nodename: no such file or directory: check that the calico/node container is running and has mounted /var/lib/calico/”
I have checked the cluster node and didnot see any flannel interface created.
All Pods on the system
