In the CKA course , under the networking section there are topics about implementation about NAT and stuff and the video says that we have discussed this before , and videos dont seem to follow that . under which course can u find these videos ??
A basic Linux course or tutorial will have these sorts of topics. We won’t delve much into topics like NAT, although it’s not that complex; it just isn’t used much in Kubernetes networking, which are “bridged”.
You may want to pause your CKA journey a bit to cover the basics, since CKA sort of assumes that you know a bit about networks, addresses, DNS, and how these things fit together. Our basic DevOps course covers a lot of these concepts, at least to the depth you’ll need for CKA. And there are similar courses and tutorials all across the internet as well.
