# 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)

      ps          List Containers

      run         Run a command inside a new Container.

## Examples

    vessel run alpine # same as above due to alpine default command

## Notice

vessel, obviously, is not a production ready container manager tool.
