The question is well-written, and the explanation is comprehensive. I'm ready to tackle this on the exam. Although, I do wonder if the Nginx pod will be able to do any cool special effects with the gVisor runtime. Maybe it'll make the Nginx logo spin or something.

Haha, gVisor, sounds like some kind of superhero sidekick. I bet it can stop a bullet with its bare hands! Alright, let's give this a try and see if my Nginx pod can do some fancy moves too.

The steps look clear, but I'm a bit concerned about the gVisor runtime. I haven't worked with it before. I'll need to research more about its capabilities and any potential gotchas.
