Kubernetes is like if someone snorted a bunch of HTTP RFCs and then decided to half-ass an operating system in an all-night bender. And then a (distributed!) propaganda machine convinced ever middle manager ever to use it.
There are two ways to look at it. It's all been purely built up via propaganda, or there is actual merit in the tool. Ironically, it's a meta-game because propaganda supports each of those views.
But personally, I think it's silly to say Kubernetes has more of a propaganda issue than any other <insert big name framework>. There are "purists" like any other tool. However, I don't let them bother me so much that I just throw the baby out with the bathwater.
I think people are just tired of arguing with people who think you need, say, an entire cluster orchestration system, and a renderer inside your renderer just to serve up some web pages. It's a lot easier to just tell people to use "boring technology". The ones who get it, get it.
Just between us, you do understand the point of an illustrative example, right? In this case, the person above me said you could have an immune system. I don't believe that's really true anymore. We've moved past it.
