   Ubuntu Jammy distributions currently.

.. zuul:rolevar:: ensure_kubernetes_microk8s_channel
   :default: latest/stable

.. zuul:rolevar:: kubernetes_runtime
   :default: docker

   Which kubernetes runtime to use for minikube; values are ``docker``,
   ``cri-o`` or ``podman``. For any other values the
   ``ensure_kubernetes_minikube_*`` options will be used instead. Please
   note that only some combinations of profiles and distros might be
   valid.
