rcr

A Linux container runtime built from scratch in Rust. Namespaces, cgroups, seccomp, capabilities, OverlayFS, and a daemonless management layer, no Docker involved.

# start the VM (Apple Silicon, via Lima)
limactl start --name=rcr lima.yaml
limactl shell rcr

# build and run
rcr run --name my-shell --image alpine /bin/sh

# just run without rebuilding
rcrx run --name my-shell --image alpine /bin/sh
