## Kubernetes Version
The current default kubernetes version used by RKE is `v1.10.1-rancher1`.
There are two ways to select a kubernetes version:
- Using the kubernetes image defined in [System Images](#rke-system-images)
- Using the configuration option `kubernetes_version`
In case both are defined, the system images configuration will take precedence over `kuberntest_version`. Since the `kubernetes_version` options was added mainly to be used by Rancher v2.0, it has a limited number of supported tags that can be found [here](https://github.com/rancher/types/blob/master/apis/management.cattle.io/v3/k8s_defaults.go#L14).
If a the version defined in `kuberntest_version` is not found ins this map, the default kubernretes version is used.
