2 Introducing Knative Serving

Serving is where I’m going to start you off in Knative, and the coming chapters will take you into a deeper dive on the major concepts and mechanisms. To begin with, I’ll spend this chapter getting you warmed up in two ways.

First, I’m going to actually use Knative. You’ll notice that I ducked and weaved around this in chapter 1. I did walk you through an example and that example was realistic. But it was also intended to whet your appetite for the whole book, and so necessarily, it needed to touch on a lot of points. A hypothetical example with diagrams and narrative is a quick way to do so.

But now, I’m going to put your fingers on a keyboard. We will use the kn CLI tool to deploy some software, change its settings, change its software, and finally, configure traffic. I won’t be doing any YAMLeering. We’ll be trying a purely interactive approach to Knative.
