Kubernetes uses the container software found on the machines under the hood. When, for instance, we install Kubernetes on Fedora's CoreOS, it will detect that Docker is available and use the Docker engine for managing the containers.

Configuring Kubernetes with SELinux support

Installing Kubernetes can be a daunting task, and several methods exist, ranging from single-node playground deployments up to commercially supported installations. One of the well-documented installation methods on the Kubernetes website is to use kubeadm for bootstrapping Kubernetes clusters.
