@@ -22,6 +22,7 @@ The following is a list of feature flags available in Rancher. If you've upgrade
- `continuous-delivery`: Allows Fleet GitOps to be disabled separately from Fleet. See [Continuous Delivery.](../../../how-to-guides/advanced-user-guides/enable-experimental-features/continuous-delivery.md) for more information.
- `fleet`: The Rancher provisioning framework in v2.6 and later requires Fleet. The flag will be automatically enabled when you upgrade, even if you disabled this flag in an earlier version of Rancher. See [Continuous Delivery with Fleet](../../../integrations-in-rancher/fleet/fleet.md) for more information.
- `harvester`: Manages access to the Virtualization Management page, where users can navigate directly to Harvester clusters and access the Harvester UI. See [Harvester Integration Overview](../../../integrations-in-rancher/harvester/overview.md) for more information.
- `imperative-api-extension`: Enables Rancher's [extension API server](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/apiserver-aggregation/) to register new APIs to Kubernetes. This flag is enabled by default. See the [Extension API Server](../../../api/extension-apiserver.md) page for more information.
- `istio-virtual-service-ui`: Enables a [visual interface](../../../how-to-guides/advanced-user-guides/enable-experimental-features/istio-traffic-management-features.md) to create, read, update, and delete Istio virtual services and destination rules, which are Istio traffic management features.
- `legacy`: Enables a set of features from 2.5.x and earlier, that are slowly being phased out in favor of newer implementations. These are a mix of deprecated features as well as features that will eventually be available to newer versions. This flag is disabled by default on new Rancher installations. If you're upgrading from a previous version of Rancher, this flag is enabled.
- `managed-system-upgrade-controller`: Enables the installation of the system-upgrade-controller app in downstream RKE2/K3s clusters, currently limited to imported clusters and the local cluster, with plans to expand support to node-driver clusters.
