The Calico CNI plugin creates the default network interface that every pod will be created with. Since we had stored the kubeadm join command, I will execute the same on my worker nodes to join the Kubernetes cluster: The above command will only start the kubelet service so we must manually enable it to auto-start after every reboot on all the worker nodes: Now check the status of kubernetes cluster on the controller node: The status of controller node and all other worker nodes are Ready so all seems good. Unless you have a specific reason for running an earlier To keep things simple, the role of a network plugin is to set up the network connectivity so Pods running on different nodes in the cluster can communicate with each other. net/bridge/bridge-nf-call-iptables sysctl to 1 to ensure that the iptables proxy functions you've created the add-on, you can update it with your custom settings. cni-metrics-helper-policy.json.
