# OpenShift and OADP Feature Gates

## FeatureGate

FeatureGate is a cluster-wide configuration resource that controls the activation of specific features in the platform.

The default enabled or disabled features in a given OpenShift version can be found in:
- [OpenShift API](https://github.com/openshift/api/blob/master/features/features.go). If there is an upstream feature not mentioned in the OpenShift it will follow upstream, listed below. In general, all the same features enabled as [upstream in the corresponding release](https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/#feature-gates-for-alpha-or-beta-features).
- [Versioned Kube Features](https://github.com/openshift/kubernetes/blob/master/pkg/features/versioned_kube_features.go), which also includes [Kube Features](https://github.com/openshift/kubernetes/blob/master/pkg/features/kube_features.go)

## FeatureGate CRD

Modify the FeatureGate CRD to control specific features in the cluster.

To enable a feature gate, add it to the enabled list. This ensures the feature is activated and its behavior is enforced.
