It we will use kubeadm to bootstrap the cluster. For installing kubeadm and for more provisioning options please refer to the official kubeadm documentation [https://kubernetes.io/docs/setup/production- the BPF kube-proxy replacement. See Kubernetes NodePort (beta) for requirements and configuration options for NodePort services. Finally, verify that Cilium has come up correctly on all nodes: kubectl
