An introduction to Kubernetes

If you have been thinking about looking at containers, then you would have come across Kubernetes at some point on your travels, so before we enable it within our Docker desktop installation, let's take a moment to look at how Kubernetes started life.

Kubernetes, pronounced koo-ber-net-eez, originates from the Greek name given to a helmsman or captain of a ship.

The method of shortening the name adopted by the Kubernetes team is called a numeronym and was devised in the 80s, and is still used today. See https://en.wikipedia.org/wiki/Numeronym for more information.
