The cluster administration overview is for anyone creating or administering a Kubernetes cluster. It assumes some familiarity with core Kubernetes concepts.
See the guides in Picking the Right Solution for examples of how to plan, set up, and configure Kubernetes clusters. The solutions listed in this article are called distros.
Before choosing a guide, here are some considerations:
Note: Not all distros are actively maintained. Choose distros which have been tested with a recent version of Kubernetes.
