vhaudiquet 479dfb79d0 refactor(rootfs): split the entry cache into cache.rs
The cache stopped being an implementation detail of the rootfs
lifecycle: entry naming, the advisory lock, digest freshness,
provisioned-layer pointers, and extraction-to-scratch are a store
in their own right. cache.rs now owns RootfsCache's paths, pointers
and extraction products; rootfs.rs keeps the lifecycle API
(PrepareRequest, PreparedRootfs, prepare, prepare_provisioned).
resolve_source moves next to its inputs in distro. Pure movement -
naming still derives its extension from the URL, next commit
changes that.

ecrou

a small microVM runtime based on libkrun

Try ecrou in the terminal

Installation

ecrou is available as a strictly confined snap:

sudo snap install ecrou
sudo snap connect ecrou:kvm

Usage

$ ecrou run -it ubuntu
root@ecrou-vm-m2glhl:/# 

Embed ecrou into your project

ecrou is both a library and a tiny CLI frontend around it. The library is embeddable into any project, allowing to use microVMs easily.

Rust

ecrou is a Rust library, which can just be called:

use ecrou::vm::RunOptions;
use ecrou::NoProgress;

fn main() -> ecrou::Result<std::process::ExitCode> {
    let code = ecrou::vm::run(
        &RunOptions {
            image: "ubuntu:resolute".into(),
            command: vec!["uname".into(), "-a".into()],
            ..RunOptions::default()
        },
        &NoProgress,
    )?;
    Ok(std::process::ExitCode::from(code.clamp(0, 255) as u8))
}
