Docker & Container Runtimes

What is Kubernetes? An intro for beginners

It’s easy to forget how new Kubernetes and containers are. Those of us who’ve already embraced them should remember we’re on the frontier. If you’re a regular reader of the CoreOS blog, you’re likely with us on that bleeding edge.

This post will be a little different than our usual. Its goal is to introduce Kubernetes to folks who aren’t on the frontier. That might be those in tech who work on the business side, or developers who have yet to make the leap into containers. To tell the tale, we’ll get a little help from everyone’s favorite frozen treat—ice cream.

Since then, our site has led to a significant increase in sales. Going on the web extended our reach from just a few brick-and-mortar locations to virtually any shippable address in America. People are hungry for ice cream, and to keep up with demand we need to scale.
