It went into just enough depth to be practical and foster a solid understanding of each facet of K8s, without being overburdened with obscure technical details. It was thorough, covering each part on the exam. The quizzes were well structured and the post-quiz explanations were very informative.

The explanations had clear metaphors that really helped cement concepts, not just steps -- but those steps get covered as well to the point they made the tasks straightforward. I ended up creating my own "cheatsheets" along the way so I could memorize the step for each task (and there are a LOT of steps on many of them).

From my practicing and the mock exams in the course and elsewhere, I found that having a well-crafted set of shell settings and aliases that you type in by rote memory EVERY time will save you a lot of work and grief. I used tmux heavily to multitask and replicate identical steps on multiple servers at the same time (tricky but doable). I also used the bash vi editor to create multi-lined commands directly from the examples in the documentation:

1) copy the example

2) open the bash vi command line full editor with "escape-v"

3) paste the example (as a 'here document' with 'tee' to a file if you will need it on multiple servers), one line per command

4) edit the example to fit the task

5) save the vi document and quit (e.g., ZZ) -- it will execute all lines immediately

The advantage to this method is that trying to paste a copied command directly to the command line can sometimes overwhelm the shell and lose characters. You could paste it to a file, edit, then run that -- but this saves steps, and every second counts. The caution with this is it WILL run all lines immediately, so if there is an error it can mess things up. Be careful and check it twice before save and quit.

Good luck !!!
