# Kubernetes controllers configuration

A $[prodname] [Kubernetes controllers](../component-resources/kube-controllers/configuration.mdx) configuration resource (`KubeControllersConfiguration`) represents configuration options for the $[prodname] Kubernetes controllers.
A $[prodname] Kubernetes controllers configuration resource (`KubeControllersConfiguration`) configures the controllers that run inside the `$[imageNames.kubeControllers]` container. These controllers monitor the Kubernetes API and reconcile cluster state with the $[prodname] datastore.

The `$[imageNames.kubeControllers]` container can run the following controllers; each is enabled by including a corresponding block under `spec.controllers`, and disabled by omitting the block.

- **Node controller** — garbage collects IP addresses, cleans up $[prodname] node data when Kubernetes nodes are removed, and optionally creates and syncs host endpoints for each node.
- **Federated services controller** — watches Kubernetes services and endpoints locally and across all remote clusters defined through [RemoteClusterConfigurations](remoteclusterconfiguration.mdx), and programs Kubernetes endpoints for any locally-configured service that specifies a federation selector annotation. See [Configuring federated services](../../multicluster/services-controller.mdx) for the usage guide.
- **Load balancer controller** — manages IPAM for Services of type `LoadBalancer`.
