I would buy the book. Just translate all "new language" concepts into well known concepts from networking and system administration. It would be best seller.

If I would only have a penny for each time I wasted hours trying to figure out what something in "modern IT" is, just to figure out that I already knew what it is, but it was well hidden under layers of newspeak...

This[0] is my take on something like that, but I'm no k8s expert -- the post documents my first contact with k8s and what/how I understood these concepts, from a sysadmin/SWE perspective.

The book I read on K8S written by a core maintainer made is very clear.
