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 |
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
$ 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
