Rust + Docker = Rocker🤘

Rocker is a minimal docker implementation for educational purposes inspired by gocker. Rocker uses linux kernel features (namespace, cgroup, chroot etc.) to isolate container processes and limit available resourses.

Usage

• Run a container

rocker run [OPTIONS] <image-name> <command>

OPTIONS:
        --cpus <cpus>
    -m, --mem <mem>
        --pids-limit <pids-limit>

• List running containers

rocker ps

• List images

rocker images

• Run a command in the existing container

rocker exec <container-id> <command>

• Delete an image

rocker rmi <image-hash>

Requisites

• libdbus (1.6 or higher)

$ cargo build
