kubeadm/#pod-network]. Standard Installation This guides takes you through the steps required to set up Cilium on Kubernetes using the cilium-etcd-operator. The cilium-etcd-operator replaces the requirement for the TLS cer�ficates between etcd peers to work correctly, a DNS reverse lookup on a pod IP must map back to pod name. If you are using CoreDNS, check the CoreDNS ConfigMap and validate that in-addr more details. Installation with external etcd This guide walks you through the steps required to set up Cilium on Kubernetes using an external etcd. Use of an external etcd provides be�er performance
