What software did Docker Inc donate to the Open Container Initiative, marking the first OCI open standard?

• A. RunC
• B. containerd
• C. crun
• D. LXC

Answer: (A)

The key idea is that OCI’s first standard focused on the runtime interface and a reference implementation. Docker contributed RunC as the initial project to serve as that reference runtime, demonstrating how containers should be executed according to the OCI runtime specification. RunC is a lightweight, low-level tool that actually spawns and runs containers, which is why it was chosen as the first standard’s reference implementation. Containerd, crun, and LXC are related in the broader container ecosystem but did not represent the first OCI standard donation. Containerd is a container management daemon that sits above the runtime, crun is another OCI-compliant runtime, and LXC is an older container technology not tied to the OCI’s inaugural donation.
