using the cilium-etcd-operator. The cilium-etcd-operator replaces the requirement for an external kvstore. You can learn more about it in the sec�on What is the cilium-etcd-operator? It is suitable for small 1.9 Linux kernel >= 4.9 Kubernetes in CNI mode Running kube-dns/coredns (When using the etcd-operator installa�on method) Mounted BPF filesystem mounted on all worker nodes Enable PodCIDR alloca�on Deploy Cilium + cilium-etcd-operator The following all-in-one YAML will deploy all required components to bring up Cilium including an etcd cluster managed by the cilium-etcd-operator.
