We just completed the switch to Rancher where I work. 1200ish engineers, mostly on Macs. So far it's worked out pretty well..fewer hiccups than I expected.
not a personal attack on you, but it blows my mind how clueless the current generation of developers become after the docker phase.
Containers will only ever be on a linux kernel or VM? Never natively on ANY other OS? Only Linux containers exist?
Developers were more clueful about containers before Docker made them wildly popular?
In practice, yes.
The root of the problem was we had third party tools which were windows only.
Linux is not the only OS that has container like things. FreeBSD had jails years earlier, Solaris had something else which I don't remember any more, and for all I know macOS may have their own native equivalent as well.
Bear in mind that Apple introduced an official hypervisor framework a few releases ago, so they could be doing something similar for containers. It wouldn't be a bad idea. :)
There's always been a mythos of a true developer. Here's a rant from 1983 about how real programmers don't use Pascal. https://www.pbm.com/~lindahl/real.programmers.html
