kubernetes itself has not convenient way of doing specific stuff like 
creating the kubernetes cluster.

So there are other tools/distri around helping you with that.

Kubeadm

  • The official CNCF (https://www.cncf.io/) tool for provisioning Kubernetes clusters (variety of shapes and forms (e.g. single-node, multi-node, HA, self-hosted))
  • Most manual way to create and manage a cluster

Disadvantages

  • Plugins sind oftmals etwas schwierig zu aktivieren

microk8s

General

  • Created by Canonical (Ubuntu)
  • Runs on Linux
  • Runs only as snap
  • In the meantime it is also available for Windows/Mac
  • HA-Cluster

Production-Ready ?

  • Short answer: YES
Quote canonical (2020):

MicroK8s is a powerful, lightweight, reliable production-ready Kubernetes distribution. It is an enterprise-grade Kubernetes distribution that has a small disk and memory footprint while offering carefully selected add-ons out-the-box, such as Istio, Knative, Grafana, Cilium and more. Whether you are running a production environment or interested in exploring K8s, MicroK8s serves your needs.

Having a footprint, where kubernetes runs within docker 
and the applikations run within docker as docker containers
it is not suitable for production.
