Linux is preety complex system too, you know, with millions lines of code and gazillion moving parts. It's probably safe to say that no one alive, including Linus himself, ever read all the codebase required for running a base linux system serving Apache with a static site. And yet we do.
Anyone who know how to code well can learn how to pack containers and run them within a kubernetes cluster in a way that will work reliably, even if those containers do nothing except serving pure html text files over port 80, and in fact the whole cluster is waste of money and it is not required and not helping a thing. It will serve the content just fine. No nukes will be hurt during the operation, don't worry.
If this is your criterium, sure. That's nice and simple and for much the same way that physics cows are perfectly spherical - this isn't how real life happens and I suspect you have enough life experience to know that this is the case.
Ironically your example is a good one, because tools like Kubernetes are what enables the proverbial cows of deploying services in heterogeneous clusters of COTS hardware to be interpreted as being spherical in the sense that they are only contained processes that execute somewhere.
And the irony is that you might seriously argue that being forced to waste time modeling cow in higher detail than a sphere is necessary or even required.
Your comment reads like stating "I am right and deep down you know that too", and that is less than pleasing.
However I have come to respect that many people are different. These are often the same people who insist on buying a new phone, never mind that they haven't understood a millionth of the old one yet.
The hammer will only suffice in the eyes of those who only envision problems that resemble nails.
But there's more to operations than occasionally hammering on a single nail.
