containert

containert serves as a simple container runtime tool designed for educational purposes. It executes binary files in secure, isolated settings using Linux cgroups and namespaces.

Usage

Run the program with the following command:

containert --binary_path [path/to/binary] --rootfs [path/to/rootfs]

• binary_path: Path to the binary you want to run in the container.
• rootfs: Path to the root filesystem for the container.

Example: (I extracted the rootfs for an ubuntu docker image)

containert --binary_path /bin/bash --rootfs ubuntu/rootfs
root@ubuntu-linux-22-04-desktop:/# ls
bin  boot  dev  etc  home  lib  lost+found  media  mnt  opt  proc  root  run  sbin  snap  srv  swap.img  sys  tmp  usr  var
