A Docker Registry HTTP API is available to facilitate distribution of images to the docker engine<ref>https://docs.docker.com/registry/spec/api/</ref> with support for image verification, resumable push and pull operations and layer deduplication.

Docker Registries can be public or private. Two main public registries are [[Docker Hub]] and [[Docker Cloud]].
