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.

Does it use the same "containers are really just running in a Linux VM" approach as Docker Desktop on macOS?

  unless you run osx on a Linux kernel, it will always be so. not a personal attack on you, but it blows my mind how clueless the current generation of developers become after the docker phase.

    I don't understand this comment on any level. 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?

      “Only Linux containers exist?“ In practice, yes.
      - maccard 2y ago
        Windows containers absolutely exist in practice.

        Yeah, but how often are they needed?
        maccard 2y ago
        My last job we ran very significant public workloads on windows containers. I don’t know the number of requests but it’s a multi million user application all around the world.

        Interesting; I may be biased because I've been involved in helping teams containerize as part of a cloud migration and only one or two cases has there been a real 'need', basically for running a Windows service that was eventually retired in favour of a lambda triggered by consuming a message in a queue.

        We were waaaaay too big to fit in lambda layers. Our containers were 8GB when I left, and that was using all sorts of tricks on the host infra to share data between running containers. The root of the problem was we had third party tools which were windows only.

    > unless you run osx on a Linux kernel, it will always be so 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. :)

    personal attack or not, you could have just left that last bit off and had a good comment. 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 https://www.pbm.com/~lindahl/real.programmers.html Kids these days...
