Multiple clusters in kubernetes

Question

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:

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

Would you like to teach me? Thanks.

It seems this has been answered by @Jonah Benton and @Oliver Charlesworth in the comments. Using kubernetes cluster federation 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 namespace, 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 deploying to a cluster federation and that page includes links for setting up a federation.

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