 Instead of using the Rancher UI to choose Kubernetes options for the cluster, advanced users can create an RKE config file. Using a config file allows you to set any of the [options available]({{< baseurl >}}/rke/v0.1.x/en/config-options/) in an RKE installation.
 
 - To edit an RKE config file directly from the Rancher UI, click **Edit as YAML**.
 - To read from an existing RKE file, click **Read from File**.

 The [Kubernetes Controller Manager](https://kubernetes.io/docs/reference/command-line-tools-reference/kube-controller-manager/) service is the component responsible for running Kubernetes main control loops. The controller manager monitors the cluster desired state through the Kubernetes API server and makes the necessary changes to the current state to reach the desired state.
