Overview

So far, we’ve been unleashing chaos on our applications and networking. That’s been very enlightening, at least to me. But there is still a lot that we should and that we can do.

One big topic that we haven’t touched yet is related to nodes.

• What happens if there is something wrong with the nodes of our cluster?
• What happens if suddenly all the applications running in a node disappear?
• What happens if a node goes down or if it’s destroyed?

Those are the subjects we’ll explore in this section. We’re going to try to figure out how to create chaos that will generate issues related to nodes of our cluster.

In the next lesson, we will be provided with a gist that contains all the commands for this chapter.
