Repository files navigation

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

It basically is a tiny version of docker, it uses neithercontainerd norrunc. Only a set of the Linux 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)

Here is the list of blog posts I've written about vessel:

1. Build Containers From Scratch in Go (Part 1: Namespaces)
2. To be continued...

go get -u github.com/0xc0d/vessel

Usage:  vessel [command]Available Commands:  exec        Run a command inside a existing Container.  help        Help about any command  images      List local images  ps          List Containers  run         Run a command inside a new Container.

Run/bin/sh inalpine:latest

vessel run alpine /bin/shvessel run alpine # same as above due to alpine default command

Restart Nginx service inside a container with ID: 123456789123

vessel exec 1234567879123 systemctrl restart nginx

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