This blog explains how to run Kubernetes on a cluster, specifically focusing on using Vagrant for simplicity. It starts with setting up the Kubernetes cluster and then shows how to run a Docker container in Kubernetes using the `kubectl run` command. The example uses the `arungupta/couchbase` image as a pre-configured Docker container for Couchbase. The blog covers topics such as creating a replication controller, checking pod status, and exposing the Couchbase Web Console through a new service. The goal is to demonstrate how to deploy and manage a Couchbase application on a Kubernetes cluster.
