I'll be honest, never learned it, worked up from network protocols, reached docker in terms of virtualization, and of course OS fundamentals.
But even in those 3 areas I haven't exhausted all the knowledge and features available.
So I'm just skeptical when someone is using k8s and hasn't mastered the fundamentals. How do they know whether they should be using a high level k8 feature or a low level os feature? Happened with docker a lot to me when I didn't know better, I was learning how to set memory limits on containers and reset policies instead of learning to do it on the OS level.
