%description
k3s is a container orchestration system for automating application
deployment, scaling, and management. It is a Kubernetes-compliant
distribution that differs from the original Kubernetes (colloquially
"k8s") in that:

  * Legacy, alpha, or non-default features are removed.
  * Most in-tree plugins (cloud providers and storage plugins) were
    removed, since they can be replaced with out-of-tree addons.
  * sqlite3 is the default storage mechanism.
    etcd3 is still available, but not the default.
  * There is a new launcher that handles a lot of the complexity of
    TLS and options.
