 This module installs and configures [Kubernetes](https://kubernetes.io/) which is an open-source system for automating deployment, scaling, and management of containerized applications. For efficient management and discovery, containers that make up an application are grouped into logical units.
 
 To bootstrap a Kubernetes cluster in a secure and extensible way, this module uses the [kubeadm](https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/) toolkit.
