When the IP address of the node changed, Rancher lost connection to the node, so it will be unable to clean the node properly. See [Cleaning cluster nodes]({{< baseurl >}}/rancher/v2.x/en/faq/cleaning-cluster-nodes/) to clean the node.

### How can I add additional arguments/binds/environment variables to Kubernetes components in a Rancher Launched Kubernetes cluster?

For more information, see the [Extra Args, Extra Binds, and Extra Environment Variables]({{< baseurl >}}/rke/v0.1.x/en/config-options/services/services-extras/) in the RKE documentation or browse the [Example Cluster.ymls]({{< baseurl >}}/rke/v0.1.x/en/example-yamls/).
