# RKE2

This flavor uses RKE2 for the kubernetes distribution. By default it configures the cluster
with the [CIS profile](https://docs.rke2.io/security/hardening_guide#rke2-configuration):
> Using the generic cis profile will ensure that the cluster passes the CIS benchmark (rke2-cis-1.XX-profile-hardened) associated with the Kubernetes version that RKE2 is running. For example, RKE2 v1.28.XX with the profile: cis will pass the rke2-cis-1.7-profile-hardened in Rancher.
```admonish warning
Until [this upstream PR](https://github.com/rancher-sandbox/cluster-api-provider-rke2/pull/301) is merged, CIS profile enabling
will not work for RKE2 versions >= v1.29.
```
