07-bootstrapping-etcd Slightly Confuses Me

[Kvaara]

Hello!

This isn't that big of a deal but I'm confused about the seventh lab. The first paragraph says: "In this lab you will bootstrap a three node etcd cluster and configure it for high availability and secure remote access." But in reality, if I'm not mistaken, the steps show you how to setup a single node etcd cluster running on the server/controller.

So, just that I understand correctly, am I implicitly required to do those steps for the other two nodes (node-0 and node-1) as well?
