By default, Kubernetes clusters require certificates and Rancher launched Kubernetes clusters have certificates automatically generated for them.
> **Note:** Even though the RKE CLI can use custom certificates for the Kubernetes cluster components, Rancher currently doesn't allow the ability to upload these in Rancher Launched Kubernetes clusters.
