## Overview

NGINX Gateway Fabric offers a way to update the control plane configuration dynamically without the need for a
restart. The control plane configuration is stored in the NginxGateway custom resource. This resource is created
during the installation of NGINX Gateway Fabric.
NGINX Gateway Fabric can dynamically update the control plane configuration without restarting. The control plane configuration is stored in the NginxGateway custom resource, created during the installation of NGINX Gateway Fabric.

If using manifests, the default name of the resource is `nginx-gateway-config`. If using Helm, the default name
of the resource is `<release-name>-config`. It is deployed in the same Namespace as the controller
(default `nginx-gateway`).
NginxGateway is deployed in the same namespace as the controller (Default: `nginx-gateway`). The resource's default name is based on your [installation method]({{<relref "/installation/installing-ngf">}}):

The control plane only watches this single instance of the custom resource. If the resource is invalid per the OpenAPI
schema, the Kubernetes API server will reject the changes. If the resource is deleted or deemed invalid by NGINX
Gateway Fabric, a warning Event is created in the `nginx-gateway` Namespace, and the default values will be used by
the control plane for its configuration. Additionally, the control plane updates the status of the resource (if it exists)
to reflect whether it is valid or not.
