<p>I am a newbie in kubernetes clustering. I have a simple question.
I am in multiple kubernetes clustering. It seems multiple clusters are available in kubernetes. So "Multiple clustering" in kubernetes means:</p>

<blockquote>
  <ul>
  <li>It is physical multiple clusters which have their own master, nodes?</li>
  <li>Or it's kind of "logical" multiple clustering in one physical clustering?(with one master and nodes)?</li>
  </ul>
</blockquote>

<p>Would you like to teach me? Thanks.</p>

<p>It seems this has been answered by @<a href="https://stackoverflow.com/users/6716781/jonah-benton">Jonah Benton</a> and @<a href="https://stackoverflow.com/users/129570/oliver-charlesworth">Oliver Charlesworth</a> in the comments. Using <a href="https://kubernetes.io/docs/concepts/cluster-administration/federation/" rel="noreferrer">kubernetes cluster federation</a> means using multiple kubernetes clusters as though they were one. It is a set of distinct clusters acting as one, not a logical division within a single cluster. (Something like that idea of a logical division might resemble a <a href="https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/" rel="noreferrer">namespace</a>, which allows for working with a restricted 'part' of a cluster in terms of resource-allowance but a namespace isn't restricted to particular nodes.) In addition to the links provided, the kubernetes documentation also has resources for <a href="https://kubernetes.io/docs/tasks/federation/" rel="noreferrer">deploying to a cluster federation</a> and that page includes links for setting up a federation. </p>

<p>I guess you know this now as the question is a little old but I thought it would help to fill in an answer.</p>
