NetworkPolicy From Memory. No Mistakes.

Tue, 31 Mar 2026 22:08:02 -0400

Cert exam incoming. Been drilling hard — writing YAML from scratch, no peeking at docs.

Today I wrote all the NetworkPolicy patterns from memory. No mistakes. 🥹

NetworkPolicy is the one topic everyone says trips them up — the ingress/egress selector logic, podSelector scoping, default deny patterns. It clicked. Apparently all this hardcore study is sinking in way more than I thought.

That’s the difference between “I think I’m ready” and “I know I’m ready.” Sure, you can look things up on the exam — but why burn time when you already know exactly what resource you need and where every field goes?

I spent 20 years in semiconductor engineering.

Good salary. Somewhat stable career, lol. Respected field. Learned a lot. For a long time, that was enough. At some point it stopped being enough — probably further back than I care to admit, but here I am.

It wasn’t a dramatic moment or a single bad day. Just a slow realization that I had spent a long time being good at something I really didn’t want to keep doing.
