What do we have to understand for the exam when it comes down to probes?
So, first of all, understand the purpose of the readiness, startup, and liveness probes.
Then practice how to configure them in a pod definition.
It's actually relatively easy to find a starting point for configuring such a pod.
And the corresponding probes, by having a look at the Kubernetes documentation.
We can usually just copy-paste a good starting point from there.
And then, just to understand the runtime behavior of those probes deeply, I would say potentially
try to introduce failure conditions and see the runtime effects of such a probe.
So, for example, you could configure a liveness probe and then introduce a problem with the
running process of your application.
And what the liveness probe should take care of is to restart the application.
See what actions are being taken by those probes at runtime.
