But it isn't a new thing on Linux. lxc, vserver, openvz, and other projects also do what zones and jails do. Docker is not the same.

- quesera 12y agoThat's fair, I was writing imprecisely. The functionality has existed (at least primitively) on Linux for some time, but culturally Linux admins have been more drawn to HW level virtualization instead. OS-level virtualization has been a part of the FreeBSD and Solaris cultures for much longer. Another fair argument is that Docker does such a good job at abstracting the configuration and management of OS-level virtualization that it truly changes things. Maybe. But if that's true, it means that Linux admins have ignored this hugely useful technology because it was hidden behind an impenetrable wall of text-based configuration.
