What is the purpose of the Open Container Initiative's Distribution Specification?

• A. Defines a specification on the open standards and API protocols for distribution of content
• B. Defines how to write container images to a filesystem
• C. Specifies network policy for Kubernetes
• D. Defines storage interface for CSI

Answer: (A)

The distribution specification in OCI defines how container images and related artifacts are distributed between registries and clients using a common API and data formats. It standardizes how you push and pull images, how blobs and manifests are addressed and retrieved (content-addressable by digest), how manifest lists reference multiple architectures, and how authentication and authorization are handled with registries. Because of this standard, tools and registries from different vendors can interoperate, enabling seamless image distribution across diverse environments. This is not about writing images to a filesystem (that relates to the image layout/spec), nor about Kubernetes network policies, nor about the storage interface for CSI.
