help CNCF Distribution FAQ

Is CNCF Distribution a Linux distribution?

No, CNCF Distribution refers to the open source registry project behind container image distribution, not a full Linux operating system. It grew out of Docker Distribution and is tied to registry workflows for container images.

What problem does CNCF Distribution solve for Kubernetes users?

It provides the registry-side mechanics for storing and serving container images that Kubernetes clusters later pull. In a typical setup, kubelet pulls images from registries that implement the OCI Distribution-style API.

How is CNCF Distribution related to Docker Registry?

The project is closely related to Docker Registry v2, the registry implementation many teams used before OCI terminology became standard. That is why developers often encounter it in paths or repos named distribution.

Is CNCF Distribution the same thing as Helm or containerd?

No, Helm packages Kubernetes manifests, and containerd runs and manages containers on nodes. CNCF Distribution is about registry storage and transfer of images, which is a different layer of the container stack.
