OCI Runtime Spec - CI/CD Glossary Definition
The OCI runtime spec is the Open Container Initiative standard defining how a container is configured and run from a filesystem bundle, including the config.json schema. It is what makes images portable across runtimes like runc and crun.
Why it matters
Because images follow the OCI image spec and runtimes follow the OCI runtime spec, an image built in CI by BuildKit runs identically under containerd, CRI-O, or Podman in production.
