From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

As I understand it, the problem that both Nix and Docker try to solve is "How do I bundle and run this application in such a way that its dependencies are explicitly specified and don't interfere with anything installed on the host system".
They have different approaches, but I think that goal is the same?
That's Nix, not NixOS.
I also wouldn't be too sure on that "explicit" part for Docker. It's somewhat isolated, sure, but everything but explicit: you can download arbitrary data from wherever you like.
No, containers further isolate the network and hardware interaction of the process etc
Unless it has changed recently, Docker is not intended to be a security layer as far as I know.
