 # Try Ozone With Kubernetes
 
+Ozone is designed to work well under Kubernetes. This document provides a guide for deploying and experimenting with Ozone on K8s, using MiniKube or a self-hosted Kubernetes cluster.

-* kubectl

 ### Deploy the Services
 The `kubernetes/examples` directory of the Ozone distribution contains Kubernetes deployment resource files for multiple use cases. By default the Kubernetes resource files are configured to use the [apache/ozone](https://hub.docker.com/r/apache/ozone) image from Docker Hub.
