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.

Nothing too shabby, but still. To run it you need docker, and after that just type

docker run -it --rm --log-driver none --read-only --net none --cap-drop=ALL --security-opt=no-new-privileges defnotgustavom/pixfire4

...and you will be greeted with a little, small, very pixelated bonfire.

"Why docker and not just a simple command?"

Mostly because of those two flags: --read-only and --net none. Can't get better than this. :^)

This also came up while in a self-learning process, but I don't want to "flex" it here.

What is the original size of the program before docker?

edit: Also the docker sandbox is not perfect for running unsafe programs. You could still have programs slow down your entire system by taking as many resources as possible. eg. forkbombs.

Doesn't docker have a flag for limiting system usage? Like max mem, cores/threads etc? I swear I remember using something like this before.

Linux has ulimit so I assume docker does aswell
