Containers and Kubernetes are 90% about raising the barriers of entry to IT (as all professions do) by making something so complex and abstract that only a small percentage of extant IT people can understand it all. Not personally complaining, because I can comprehend it all just fine.
This was inevitable and it really began when you saw helpdesk-level jobs requiring CS degrees which means they de facto required calculus. I don’t know about you but I never did even a little bit of calculus when I was working helpdesk. Or even arithmetic for that matter.
The other 10% is that containerization is the hot new tech that is going! To solve! All our problems! And of course it doesn’t and never will because though they do have their uses, I’ve been in IT a long time and no tech ever solves all of anyone’s problems and often, as containers do, they create loads more that then have to be solved with other tools.
Containers are really about the pseudo-professionalization of IT and wall-building, not about the tech itself. They are designed to keep IT white (or make it whiter), to corporatize it, and to make sure the non-college crowd has fewer paths of entry into the field. Sad to see but it was inevitable.
