CRUN
Lightweight C OCI runtime as a runc alternative
GPL-2.0
ABOUT
runc works, but each container process costs more memory than a C runtime needs. On packed inference nodes that tax adds up. crun implements the OCI runtime spec with a smaller footprint so Podman, CRI-O, and Kubernetes can start more sandboxes per host.
INSTALL
brew install crunINTEGRATION GUIDE
1. Swap runc for a lighter OCI runtime on dense model-serving nodes
2. Run Podman or CRI-O with crun to cut per-container memory
3. Start OCI bundles directly when debugging a failed GPU container
4. Compare runc vs crun start time for short-lived training sidecars
