This is the simplest installation method as it only depends on Kubernetes on all worker nodes Recommended: Enable PodCIDR allocation (--allocate-node-cidrs) in the kube-controller-manager (recommended) Refer to the section Requirements for detailed instruction on how to prepare state propagation caused by Kubernetes events. If you do not want Cilium to store state in Kubernetes custom resources (CRDs). Requirements Make sure your Kubernetes environment is meeting the requirements:
