Containers

A simple container runtime written in rust! Just for fun

Status:

How to use

Run the script setuproot.sh. This will donwload an alpine linux image, and setup the directorty structure needed. The executable must be run as root.

Running a contianer

The run subcommand will create a new container

Example: ./containers run /bin/bash Containers will output their ID (just the PID of the init process)

Executing a command in an already running container

The exec subcommand executes the following command in an existing container. Specify the contaienr by PID.

Example: ./containers exec 213 /bin/bash

TODO

• Properly isolate the filesystem
• Isolate the network
• Drop capabilities so that root in the container is powerless
• Add cgroups to restrict containers resource access
