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.

Why not Docker?
Because podman :)
Points for the correct answer. I work on systems for spacecraft and podman is what we use on those for containerization (better option for a couple reasons)... but we literally just SAY docker to the suits, because that's what they've heard of. Which is why I said docker to this guy.
I heard of docker but I'm not really sure what it is, is it free? is it hard to set everything up? Can my computer handle it?
Docker and podman aren't too bad nowadays I don't think assuming you're not running something huge
(Podman is another tool that does the same thing as docker)
Docker and podman containers are basically like throwaway mini-vms that contain one application to ensure it will always run no matter where so long as the machine you're running them on can run docker
They can run CLI stuff just fine, I'm not sure about desktop apps someone smarter than me will probably tell you about that
Docker can absolutely run desktop apps.
FOSS lightweight ”virtual machine” (it’s not quite a VM but it’s similar conceptually. It’s much lighter on your system than a VM).
Easy to install, setting it up for your use case may take some coding if it isn’t common (bash scripting experience will help).
Docker and Podman are both free. Podman is the lighter weight, more FOSS, also slightly more DIY option, they are intercompatible - I work on systems for spacecraft and Podman is what we use on those because it's lighter weight. If you want to run something in docker, ChatGPT is actually pretty good at talking you through the specific setup (at least that's been my experience).
