    Yawn. IBM/AIX's WPARs & LPARs, Sun/Solaris' dynamic system domains & zones, BSD jails. How many times are we going to pat ourselves on the back for reinventing the wheel?

      Most of those are shared kernel, though, which is very much what you want to avoid if security is a primary goal.

        Docker is a shared kernel.

          Yes, and this article is about Docker Desktop running it in a VM with its own kernel.

            Running all the containers with a shared kernel...

            Yeah, if you are going to run Linux software on Mac or Windows then you'll need a VM. But security is not the reason for a VM.
