Kubernetes Inside Story:

“We had 13 other names we couldn’t get past Google’s legal department. It was the last day, and I had to pick something. I was driving in to work, and I thought, ‘Well, [the technology] is like driving a container ship. What would the helmsman be called?’ So I tried to find something exotic. I had no idea what the Greek for that was. I had to look it up.”
