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.

Docker is not your average GUI text editor or video player. It is supposed to be a TUI-first container app, similar to Podman, Incus, etc. The GUI applet is something you can add for your convenience.
A container is somewhere between running on bare metal vs virtual machine, in the sense that it is an ephemeral, isolated system, running on the same kernel with minimal overhead.
Docker for Windows runs the whole Linux kernel in VM. Basically, now you're running a container inside a VM. That's a lot of overhead, if you understand what that means. And btw, the desktop app for Windows is available on Linux. It's just that you don't really need it.
