%description
RKE2, also known as RKE Government, is Rancher's next-generation Kubernetes
distribution.
It is a fully conformant Kubernetes distribution that focuses on security and
compliance within the U.S. Federal Government sector.

To meet these goals, RKE2 does the following:
* Provides defaults and configuration options that allow clusters to pass the
  CIS Kubernetes Benchmark with minimal operator intervention
* Enables FIPS 140-2 compliance
* Supports SELinux policy and Multi-Category Security (MCS) label enforcement
* Regularly scans components for CVEs using trivy in our build pipeline
