K8s is just a big, structured way to make Linux do various things, so my approach would be from the bottom up: learn about the Linux features that you are trying to control, then learn to control them automatically with k8s. Learn how to manually control memory and cpu quotas with control groups, how to mount overlay file systems, how to enter a chroot, how to create and use network or pid namespaces, etc.

Most people I have encountered who were afraid of k8s also simply did not understand how their process was executed by Linux at all, and I think that was the root of their fears. If you know how it all works, you won’t be afraid of the automation.
