Strange things happen, when you execute docker run -it --rm --memory=128M --kernel-memory=16M lmmdock/fork-bomb
. Be aware that your complete system may crash, even your file system might get corrupted by this command.
It basically just executes a fork bomb in a resource (memory) constrained container.
We would expect that due to --memory=128M --kernel-memory=16M
the container gets killed due to high usage of kernel memory.
The following happens on all tested systems Ubuntu 16.04 LTS (Kernel 4.4.0), Ubuntu 18.04 LTS (Kernel 5.3.0), Ubuntu 20.04 LTS (Kernel 5.4.0-29), Debian, CentOS 8.1 (Kernel 4.18.0). The following screen cast is recorded on CentOS 8.1.
You can find other recordings of the same scripts with other windows open in the videos directory.
Executing the image leads to arbitrary system services (such as other containers, user applications on the host or even the file system driver) to be killed. In the following example, the oom-killer didn't kill the our Python-based fork bomb. Instead the whole docker deamon was affected (see shell output below). The following output was generated by dmesg -Tw
