This enables the OS to be treated as a Kubernetes resource, monitored by the

quick installation procedure. The default settings will store all required state using Kubernetes custom resource definitions (CRDs). 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:

it can be declar- ative based on a source of truth. Based on a reconciliation loop, the GitOps controller makes changes to the cluster by deploying new instances, once those changes have been committed by the GitOps controller. What’s powerful about this method is that you no longer have to wait for the CI/CD process to finish before detecting and correcting drift. The GitOps controller acts as both These components include the source controller, the Kustomize controller, the Helm controller, the notification controller, and the image automation controller. Flux was born out of the best practices
