 >**NOTE**: [CustomResourceDefinitions](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) (CRDs) have been moved from `templates` to `crds` directory in the helm charts. To manage the lifecycle of the CRDs during install/upgrade, helm `pre-install` and `pre-upgrade` hook has been added. This hook will create a pod that runs only on **linux** nodes and deploys the CRDs in the Kubernetes cluster.
