# vessel
A tiny educational-purpose project to create containers, written in Go.

It basically is a tiny version of docker, it uses neither [containerd](https://containerd.io/) nor [runc](https://github.com/opencontainers/runc). Only a set of the Linux features.

## Features
Vessel supports:
* __Control Groups__ for resource restriction (CPU, Memory, Swap, PIDs)
* __Namespace__ for global system resources isolation (Mount, UTS, Network, IPS, PID)
* __Union File System__ for branches to be overlaid in a single coherent file system. (OverlayFS)
