Resolution ran before the cache was consulted, so every run of alpine:3.23, ubuntu or any floating alias hit the CDN or changelogs.ubuntu.com, and an offline run of a cached image died in resolution instead of booting. The boot path now asks the cache first: an alias boots the newest cached entry of its distro, within the series or the edge flavor it floats in, and resolves upstream only on a miss; pull and --no-cache still resolve upstream. Exactly-named references (Ubuntu YY.MM, known codename, Alpine X.Y.Z) resolve offline on every path; resolve_source folds into the policy, which lives with the cache it consults.
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))
}
