A run blocked on the cache-entry flock was silent: the wait went to the log sink, which renders nowhere by default, so the CLI read as a hang. The Progress trait gains message() - a status line outside the counted-operation protocol, defaulting to a no-op so existing sinks keep compiling - and the flock wait reports what it is waiting for. The CLI renders messages on the active bar and spins one up when no operation is active.
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))
}
