Setting up an isolated container based on a Docker image filesystem (which is by default [busybox](https://hub.docker.com/_/busybox)) is the goal of the work.

The article Linux containers in a few lines of code served as the foundation for the container source code.

• Filesystem, processes and network interfaces isolated from the host system.
• The filesystem is persistent and stored as .img file (ext4)

sudo make rootfs
sudo make compile
sudo make run

Use the sudo for every make command.

Makefile is configured to create rootfs.img file from busybox image, change if needed.

• make rootfs

  Create new rootfs.img file. This file has to exist for the container to run.

• make compile

  Compile the container source, creating ./container file

• make run

  This runs two actions one after another:

  • make shell

    Runs /bin/sh in the container.

  • make restore

    Restore procfs, remove rootfs.img mount and loop.
