In addition, if neither `kubernetes_version` nor `system_images` are configured in the `cluster.yml`, RKE will apply the default Kubernetes version for the specific version of RKE used to invoke `rke up`. The default Kubernetes version for each RKE version can be found in [the RKE release notes](https://github.com/rancher/rke/releases/). Having configured the `kubernetes_version`, ensure that any `system_images` configuration is absent from the `cluster.yml`, and then invoke `rke up` to upgrade Kubernetes.
