Runc
runc is a CLI tool for spawning and running containers on Linux according to the OCI (Open Container Initiative) specification. It is the reference implementation of the OCI runtime specification and is used as the default low-level container runtime by Docker, containerd, Podman, and other container platforms. runc manages container lifecycle operations including creating, starting, pausing, resuming, killing, and deleting containers. It implements the OCI Runtime Specification and exposes a command-line interface that higher-level runtimes use to manage individual container instances. runc also supports checkpoint/restore via CRIU, rootless containers (no root privileges needed via user namespaces), cgroup v2, seccomp syscall filtering, AppArmor, SELinux, and Intel Memory Protection Extensions. The current stable release line is 1.3.x (runc 1.5.0 expected late April 2026).
