Am I missing something? There seems to be very little substance here: No link to the presentation itself, only slides that lay a very ordinary introduction. Mentioning GitHub stars may have been the first red flag
There is a link to the presentation but yeah, there's not much substance in it either, a lot of nuance is skipped over, to the point where I'd consider it just wrong in places.
Some examples:
"Service object - Grouping object that gives you a stable IP (virtual IP) for the pods that have a certain LABEL": yes, you can use a Service to give your service a "stable IP", but that's just one type of Service; and yes, you can use a Service to target pods with a certain label, but selectors can do more than just that. (Also, what is a "virtual IP"?)
"Containers (Docker)" containers != docker
"Containers in a pod share the same IP address (localhost) and port space" this bit has been cribbed from "Kubernetes in action" (chapter 3 "Understanding how containers share the same IP and port space
": "they share the same IP address and port space") but for some reason they've inserted the "(localhost)" bit which is incorrect.
You can probably find better introductions on YouTube. The k8s docs are also quite understandable in themselves.
fair enough, but nothing actually clicked for me personally until I got my hands dirty, and actually used it....then all the components made sense......I tried to give a sense of it in the presentation....
