Show HN: Kern – container and resource runtime in a 1.5 MB binary, no daemon
41points
I built kern because I needed a fast, zero-daemon tool to set CPU/RAM limits and run isolated tasks without the overhead of Docker. It's a single 1.5MB Rust binary using OCI images, cgroup v2, and namespaces. Boxes start in ~3.5ms. It's not a Kubernetes CRI or a microVM, just a standalone container and resource runtime for CLI and agents.
