A tiny container runtime written in Rust. The idea is to support a minimal isolated containers without using existing runtimes.

Feature	Description	State
Chroot	Change the root directory	✅
Mounts	Mount files and directories to container	✅
Namespaces	Isolation of various resources	✅
Cgroups v2	Resource limitations, etc	TODO
Hooks	Add custom processing during container creation	TODO

Usage

container-run 

USAGE:
    container run --fsroot <FSROOT> <APP> [ARGUMENTS]...

ARGS:
    <APP>             Specify the path to the application to run
    <ARGUMENTS>...    Arguments to be passed to the app

OPTIONS:
    -f, --fsroot <FSROOT>    Specify the root directory path
    -h, --help               Print help information

Create and run a container

$ mkdir alpine-rootfs
# use docker to export alpine into the rootfs directory
$ docker export $(docker create alpine) | tar -C alpine-rootfs -xvf -

Then you can run applications inside the container:

cargo build && sudo ./target/debug/container run -f alpine-rootfs sh
