title: What does Kubernetes actually do?
body: <p><a href="https://github.com/kubernetes/kubernetes" rel="noreferrer">Kubernetes</a> is billed as a container cluster "scheduler/orchestrator", but I have no idea what this means. After reading the Kubernetes site and (vague) GitHub wiki, the best I can tell is that its somehow figures out what VMs are available/capable of running your Docker container, and then deploys them there. But that is just my guess, and I haven't seen any concrete verbiage in their documentation to support that.</p>
  
  <p><strong>So what is Kubernetes, <em>exactly</em>, and what are some <em>specific</em> problems that it solves?</strong></p>
