history
Project history and usage
crun is a fast, low-memory OCI container runtime written in C. It is a system package rather than an application framework: users and higher-level tools call it to create and manage containers from OCI runtime bundles.
Project history
The official README frames crun as an alternative implementation of the OCI runtime specification. Its rationale is that a low-level container runtime benefits from being written in C, and that crun can also be used as a library instead of only as an external process.
The public tag history begins with 0.4 in 2019, reaches 1.0 in 2021, and continues through frequent 1.x releases. Recent release notes show steady work on security hardening, cgroups, mount handling, CRIU integration, krun integration, idmapped mounts, and runtime compatibility.
Adoption history
crun is distributed broadly through Linux and source package ecosystems, including Alpine, Debian, Fedora/DNF, Nix, pacman, Ubuntu, zypper, and Homebrew. Its broad packaging footprint reflects its role as a drop-in OCI runtime option for systems using container engines such as Podman.
How it is used
crun is used where OCI runtime compatibility, startup latency, small memory footprint, and C library integration matter. The README compares it with runc, highlights faster startup and lower memory usage, and documents build dependencies across Fedora, RHEL, Ubuntu, Alpine, and openSUSE Tumbleweed.
Package users generally do not invoke crun for application logic; they install it so container engines and scripts can select it as the OCI runtime. Build-time options such as shared libraries and static Nix builds matter for distribution maintainers.
Why package nerds care
crun is important to package history because it made the OCI runtime layer more diverse than the Go-based runc default. Its C implementation, library mode, reproducible static build path through Nix, and heavy distro packaging make it a low-level dependency that package maintainers care about for performance, hardening, and container stack composition.
Timeline
- 2019: 0.4 public tag
- 2021: 1.0 release
- 2025: 1.25 and 1.26 releases add hardening and CRIU-related changes
- 2026: 1.28 release
Related projects
- crun implements the Open Containers Initiative runtime specification and is commonly discussed alongside runc, Podman, CRIU, libkrun/krun, Nix, and Linux cgroup/systemd integration.
