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.

I consider myself to be pretty okay at Linux - I'm no pro but I've been daily driving Linux for 10+ years, can troubleshoot most things, I've installed Arch from scratch without the installer script, I can setup and maintain NixOS without much trouble, I can automate stuff with Bash etc. But I still don't understand Docker even a little bit. I don't know why but I just can't get my head around it. I've even searched for the "Explain Docker to me as if I'm five years old" type of guides and I still just bounce of it.
You are not on your own, I just can't get my head around docker either on paper it make sense but it seems just enough of a difference to melt something in my brain. Added to the fact that docker fucks around with firewall rules thinking it's the only thing of importance on the system, breaking KVM networking in the process. It's just not something I trust to play well with others.
