Container

This is a very simple container made using C language and based on Namespaces and Cgourps

Instalation

You need to install a Cgroup tool before

sudo apt-get install libcgroup1 cgroup-tools

Run your Container

Before runing your container you should build a new root files system for your container Run the following command in your prompt for building a new root

python3 build-root.py

NB: this command may take much time to run

To run your container, run and execute the container.c file using the following commands

gcc -o container container.c
sudo ./container hostname # hostname is an Argument

if you dont have gcc installed run the following commands

sudo apt update
sudo apt install gcc

Test your Container

Memory limit test

For testing the memory limit of your container you can run and execute hungry.c file in the the container's shell

gcc -o hungry hungry.c
./hungry

Or you can run the python script hungry.py using the following command

python3 hungry.py

NB: Sometimes the memory can exceed the limits because the swap memory not set to 0, to fix this problem run the following command

sudo echo 0 > /sys/fs/cgroup/memory/your_new_cgroup/memory.swappiness
