Why is Docker a good example in understanding Open Standards?

• A. Because Docker is the only container technology
• B. Because Docker prohibits cross-tool interoperability
• C. Because Docker has been instrumental in the creation of Open Standards and Open Contributions
• D. Because Docker is a hardware standard

Answer: (C)

Open standards are publicly defined specifications that let different tools and platforms work together. Docker is a good example because it helped popularize container technology and, in doing so, spurred the creation of open specifications for containers. The Open Container Initiative, formed with Docker and other contributors, standardizes the container image format and the runtime interface. With these open specs, runtimes like runc, containerd, and CRI-O can run the same images, and tooling across the ecosystem remains interoperable, showing how open standards enable portability and collaboration. The other statements miss the mark: there are many container technologies, Docker does not block interoperability, and it isn’t a hardware standard.
