Still don't understand the use-case
A lot of these technologies (including Docker) are supposedly to simplify managing infrastructure.
In my experience all they do is take a lot of previous manual work and create a huge burden elsewhere.
I'm not convinced the learning curve and management of a K8s cluster really has as many advantages as people who use it like to think. I mean it involves a metric fuckton of work, months of learning how to use it, and nowhere to hide when it all goes wrong.
At least some of the manual management methods used previously were more tried and tested. They need to focus on usability, rather than telling the 1% who think it's amazing about how great it is - they are already the converted.
